Sorry for the very late response to your proposal. Please find below the
first patch which will integrate the existing mce-test to LTP. I had just
done a sanity checking of building it. The following patch will still need:
1) Exclusive testing and sharing those results with the LTP community,
2) Comments for and rewriting of this patch for coding styles,
3) Sign off from Huang Ying <ying.huang@intel.com>, or, the concerned Authors,

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the

+MCE test suite HOWTO
+====================
+
+11 November 2008
+
+Huang Ying
+
+Section 4.2 (Test with kdump test driver) is based on the README of
+LTP kdump test case.
+
+Abstract
+--------
+
+This document explains the structure and design of MCE test suite, the
+kernel patch and user space tools needed for automatic tests, usage
+guide and how to add new test cases into test suite.
+
+0. Quick shortcut
+------------------
+- Get mcelog git version from
+git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git.
+and install in /usr/sbin (or rather first in your $PATH)
+
+git clone git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git
+cd mcelog
+make
+sudo make install
+
+- Get mce-inject git version from
+git://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git.
+
+git clone git://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git
+cd mce-inject
+make
+sudo make install
+
+- Run make test-simple
+This will do the basic tests, but not the more complicated kdump ones.
+For more information on those read below.
+
+1. Introduction
+---------------
+
+The MCE test suite is a collection of tools and test scripts for
+testing the Linux kernel MCE processing features. The goal is to cover
+most Linux kernel MCE processing code paths and features with
+automation tests.
+
+If you just want to start testing as quickly as possible, you can skip
+section 2 and section 3, and go section 4.1 directly.
+
+
+2. Structure
+------------
+
+The main intention behind the design is to re-use test cases amongst
+various test methods (represented as test drivers), such as kdump
+based, kernel MCE panic log (tolerant=3) based, etc.
+
+2.1 Test cases
+
+Test cases are grouped into test case classes. The test cases in one
+class share the similar triggering, result collecting and result
+verifying methods. They can be used in same set of test drivers. The
+interface of a test case class is a shell script, usually named as
+cases.sh under a sub-directory of cases/. The following command line
+option should be supported by the test case class shell script:
+
+cases.sh enumerate enumerate test cases in class, print test
+ case names to stdout
+cases.sh trigger trigger the test case
+cases.sh get_result get the result of test case
+cases.sh verify verify the result of test case, and print
+ the verify result to stdout
+
+When execute cases.sh [trigger|get_result|verify], the test case is
+specified via environment variable this_case, which must be one of the
+test case names returned by "cases.sh enumerate".
+
+Other environment variables are also used to pass some information
+from driver to test cases, such as:
+
+this_case name current test case
+driver name of test driver
+klog file name which holds kernel log during test
+KSRC_DIR (for gcov) kernel source code directory
+GCOV (for gcov) gcov collection method
+vmcore (for kdump) vmcore file name
+reboot (for kdump) indicate there is a reboot between test
+ case trigger and test case verify, some
+ context has been gone.
+
+Several test case classes are provided with the test suite. They are
+all based on mce-inject MCE software injection tool, and follows same
+structure.
+
+cases/soft-inj/<class name>/cases.sh Interface of the test case class
+cases/soft-inj/<class name>/data/ Directory contains data file for
+ mce-inject tool.
+cases/soft-inj/<class name>/refer/ Directory contains data file for
+ reference MCE records if necessary.
+
+For document of various test cases, please refer to doc/cases/*.
+
+2.2 Test drivers
+
+Test drivers drive the test procedure, its main structure is a loop
+over test case classes specified in configuration file. For each test
+case class, test driver loops over test cases returned by "cases.sh
+enumerate". And, for each test case, it calls "cases.sh" to trigger,
+get_result and verify the test case. Test driver also do some common
+work for test cases, such as kdump driver collects vmcore file, and
+invoking gcovdump command to get gcov data file.
+
+The interface of test driver is driver.sh, which is usually put in
+drivers/<driver_name>/ directory. The test configuration file should
+be used as the only command line parameter for driver.sh. Test case
+classes should be specified in test configuration file as CASES
+variable, details below.
+
+2.3 Test configuration file
+
+Test configuration file is a shell script to specify parameters for
+test drivers and test cases. It must be put in config/ directory. The
+parameters are represented as shell variables as follow:
+
+CASES Name of test case classes, separate by
+ white space.
+START_BACKGROUND Shell command to start a background process
+ during testing, used for random testing.*
+STOP_BACKGROUND Shell command to stop the background process
+ during testing.
+COREDIR (for kdump) directory contains Linux kernel crash core
+ dump after kdump.
+VMLINUX (for kdump, gcov) vmlinux of Linux kernel
+GCOV (for gcov) Enable GCOV if set none zero.
+KSRC_DIR (for gcov) Kernel source code directory
+
+* To test MCE processing under random environment, a background
+ process can be automatically run simultaneously during MCE
+ testing. The start/stop command is specified via START_BACKGROUND
+ and STOP_BACKGROUND.
+
+2.4 Test result
+
+After test, the general test result will go results/<driver_name>/result.
+The format of general test result is as follow:
+
+<test case name>:
+ Passed: item 1 description
+ Failed: item 2 description
+ ...
+ Passed: item n description
+
+One blank line is used to separate test cases.
+
+Additional test result for various test cases will go
+"results/<driver_name>/<case_name>/<xxx>. For in-package test case
+class, additional test results include:
+
+results/<driver_name>/soft-inject/<case_name>/klog
+ Kernel log during testing
+results/<driver_name>/soft-inject/<case_name>/mcelog
+ mcelog output during testing
+results/<driver_name>/soft-inject/<case_name>/mcelog_refer
+ mcelog output reference
+results/<driver_name>/soft-inject/<case_name>/mce_64.c.gcov (for gcov)
+ gcov output file
+
+
+3. Tools
+--------
+
+3.1 mce-inject
+
+mce-inject is a software MCE injection tool, which is based on Linux
+kernel software MCE injection mechanism. To inject a MCE into Linux
+kernel via mce-inject, a data file should be provided. The syntax is
+similar to the logging output by mcelog with some extensions.
+Please refer to the documentation of mce-inject for more information.
+
+The mce-inject program must be executable in $PATH.
+
+3.2 mcelog
+
+mcelog read /dev/mcelog and prints the stored machine check records to
+stdout. It is used by MCE test suite to verify MCE records generated
+by kernel is same as reference records, at most time, same as input
+records. The current git mcelog version is needed for MCE test suite to
+work properly. Please refer to document of mcelog for more
+information. The latest mcelog can be gotten via git snapshot from
+git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git.
+
+Note you need the git version of mcelog available in $PATH.
+
+3.3 readcore
+
+readcore read crash dump core file and output memory contents at
+specified virtual address with specified length or zero
+terminated. readcore is used to read some kernel information from
+/proc/kcore and kdump core file. The source code of readcore is put
+in tools/readcore. For more information about readcore please refer to
+README of readcore, which is in tools/readcore/README.
+
+3.4 gcovdump
+
+gcov is a test coverage tool, the original implementation is used for
+user space program only. LTP (Linux Test Project) provides the kernel
+gcov support. But MCE test involves panic or kdump, so gcovdump is
+developed to dump gcov data from kdump crash dump core. gcovdump has
+been merged by LTP cvs. For more information please refer to gcovdump
+document. The latest gcovdump can be gotten from cvs:
+http://ltp.cvs.sourceforge.net/viewvc/ltp/utils/analysis/gcov-kdump/.
+
+
+4. Usage Guide
+--------------
+
+4.1 Test with simple test driver
+
+4.1.1 Simple test driver
+
+The simple test driver just call cases.sh of test cases one by one in
+a loop. So it is not permitted for test cases to trigger real panic or
+reboot during test. For MCE testing, a special processing mode to just
+log everything in case of MCE is used for the simple test driver, it
+is enabled via set MCE parameter "tolerant=3" during
+testing. "tolerant" can be set via writing:
+ /sys/devices/system/machinecheck/machinecheck0/tolerant
+
+4.1.2 test instruction
+
+The following is the basic test instruction, for some additional
+features such as gcov support, please refer to corresponding
+instructions.
+
+a. Linux kernel and user space tools as follow should be installed
+
+ - A Linux kernel with MCE injection support. Latest Linux kernel
+ MCE injection patches can be found at:
+ git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-mce-2.6.git
+ - mce-inject tool (see 3.1)
+ - mcelog with proper version (see 3.2)
+
+b. Modify config/simple.conf or create a new test configuration
+ file. Refer to section 2.3 for more instruction about test
+ configuration file.
+
+c. Run "make". Carefully check for any errors.
+
+d. To be root and invoke simple test driver on test configuration file
+ as follow
+
+ drivers/simple/driver.sh config/simple.conf
+
+e. General test result will go results/simple/result. Test log will go
+ work/simple/log. Additional test results for various test cases
+ will go results/simple/<test case>/<xxx>. For more details about
+ in-package test case class, please refer to section 2.1.
+
+
+4.2 Test with kdump test driver
+
+4.2.1 kdump test driver
+
+The kdump test driver is based on the kdump test case in Linux Test
+Project, thank LTP for their excellent work!
+
+The kdump driver helps run tests which trigger crash/panic and
+generate result and report via kdump. The test scripts cycle through a
+series of crash/panic scenarios. Each test cycle does the following:
+
+a. Triggers a test case which triggers crash/panic (MCE with tolerant=1).
+b. Kdump kernel boots and saves a vmcore.
+c. System reboots to 1st kernel.
+d. Verifies test case, generate result and report.
+e. After a 1 to 2 minute delay, the next test case is run.
+
+4.2.2 test instruction
+
+Follow the steps to setup kdump test driver.
+
+The test driver is written for SuSE Linux Enterprise Server 10 (and
+onward releases), OpenSUSE, Fedora, Debian, as well as RedHat
+Enterprise Linux 5. Since KDUMP is supported by the above mentioned
+distro's the test driver was written and tested on them. Contribution
+towards supporting more distributions are welcome.
+
+a. Install Linux kernel with MCE injection support. Latest Linux
+ kernel MCE injection patches can be found at: FIXME url.
+
+b. Install these additional packages:
+
+ For SLES10 or OpenSUSE Distro:
+
+ * kernel-kdump
+ * kernel-source
+ * kexec-tools
+
+ For RHEL5 or Fedora distro:
+
+ * kexec-tools
+ * kernel-devel
+
+c. In addition to bzImage and modules of Linux kernel should be
+ installed on test machine, the vmlinux of Linux kernel should be
+ put on test machine and specified via VMLINUX in test configuration
+ file.
+
+d. Make sure the partition where the test driver is running has space
+ for the tests results and one vmcore file (size of physical
+ memory).
+
+e. Create a new test configuration file or use a existing one in
+ config/, such as kdump.conf. Note: not all test case classes can be
+ used with kdump test driver, see "important points" below.
+
+f. Run "make". Carefully check for any errors.
+
+g. To be root and run "drivers/kdump/driver.sh <conf>"
+
+h. After test is done, the test log of the last run of kdump driver will
+ be displayed on main console.
+
+Few Important points to remember:
+
+- kdump test driver request that a real panic should be triggered when
+ test case is triggered. So not all test case classes can be used
+ with kdump test driver, for example, all test case classes for
+ corrected MCE can not be used with kdump test driver.
+
+- If you need to stop the tests before all test cases have run, run
+ "crontab -r" and "killall driver.sh" within 1 minute after the 1st
+ kernel reboots. Then, if you'd like to carry on tests from that point
+ on, run:
+ rm work/kdump/stamps/setupped
+ drivers/kdump/driver.sh <conf>
+ If you'd like to start tests from the beginning, run:
+ make reset
+ drivers/kdump/driver.sh <conf>
+
+- If a failure occurs when booting the kdump kernel, you'll need to
+ manually reset the system so it reboots back to the 1st kernel and
+ continues on to the next test. For this reason, it's best to monitor
+ the tests from a console. If possible, setup a serial console (not a
+ must, any type of console setup will do). If using minicom, enable
+ saving of kernel messages displayed on minicom into a file, by
+ pressing ctrl+a+l on the console. Else, when it is observed that the
+ kdump kernel has failed to boot, manually copy the boot message into
+ a file to enable the debugging the cause of the hang.
+
+- The results are saved in results/kdump/result, which also shows
+ where you are in the test run. When the "Test run complete" entry
+ appears in that file, you're done. Verbose log can be found at
+ work/log.
+
+- The test machine would be unavailable for any other work during the
+ period of the test run.
+
+4.3 Gcov support
+
+Gcov is a test coverage tool. It can be used to discover untested
+parts of program, collect branch taken statistics to optimize program,
+etc. In MCE test suite, it is used to get test coverage, that is,
+which C statements are covered by each test case.
+
+Gcov support is optional, if you don't care about test coverage
+information, just skip this section.
+
+a. Make sure your kernel has gcov support. You can find lasted kernel
+ gcov patches from:
+ http://ltp.sourceforge.net/coverage/gcov.php
+
+ A README for kernel gcov can be found from:
+ http://ltp.sourceforge.net/coverage/gcov/readme.php
+
+ Notes: CONFIG_GCOV_ALL does not work for me. Add the line
+ EXTRA_CFLAGS += $(KBUILD_GCOV_FLAGS)
+ to the respective Makefiles are more stable. For example, this line
+ can be added into "linux/arch/x86/kernel/cpu/mcheck/Makefile"
+
+b. If you want to use gcov with kdump test driver, please install
+ gcovdump tool(see section 3.4). The latest gcovdump can be gotten
+ from cvs:
+ http://ltp.cvs.sourceforge.net/viewvc/ltp/utils/analysis/gcov-kdump/.
+
+c. Linux kernel source source code should be put on the test
+ machine. Its root directory should be specified in test
+ configuration file via KSRC_DIR.
+
+d. In addition to bzImage and modules of Linux kernel should be
+ installed on test machine, the vmlinux of Linux kernel should be
+ put on test machine and specified via VMLINUX of test configuration
+ file.
+
+e. Make sure gcov is available in your test system. It comes with gcc
+ package normally. If kdump test driver is used, a tool named
+ gcovdump is also needed to dump *.gcda from crash dump image.
+
+f. In test configuration file, make sure the following setting is
+ available:
+
+ # enable GCOV support
+ GCOV=1
+ # kernel source is needed to get gcov graph
+ KSRC_DIR=<kernel source directory>
+ VMLINUX=<vmlinux>
+
+g. After testing, *.c.gcov will be generated in test case result
+ directory, such as
+ results/kdump/soft-inj/non-panic/corrected/mce_64.c.gcov.
+
+h. To merge gcov graph data from several test cases, a tool named
+ gcov_merge.py in tools sub-directory can be used. For example,
+
+ tools/gcov_merge results/kdump/soft-inj/*/*/mce_64.c.gcov
+
+ Will output merged gcov graph from all test cases under
+ soft-inj. This can be used to check coverage of several test cases.
+
+4.4 tool
+
+Some tools are provided to help analyze test result.
+
+- tools/grep_result.sh
+
+ Grep from general test result (results/<driver_name>/result) in
+ terms of test case instead of line, because the result of one test
+ case may span several line.
+
+ Usage:
+ cat results/<driver_name>/result | tools/grep_result.sh <grep options>
+
+ Where <grep options> are same as options available to /bin/grep.
+
+
+5. Add test cases
+-----------------
+
+5.1 Add test case to in-package test class
+
+All in-package test classes use mce-inject software injection tool and
+follows same structure. The steps to add a new test case is as follow:
+
+a. Find an appropriate test case class to add your test case.
+
+b. Add a new mce-inject data file into to cases/soft-inj/<class name>/data/.
+
+c. If the reference mcelog is different from mce-inject input data
+ file, put that reference file into cases/soft-inj/<class_name>/refer/.
+
+d. In cases/soft-inj/<class name>/cases.sh, there are shell commands
+ "case" in shell functions get_result() and verify(). Add a branch
+ in each shell command "case" for your test case.
+
+5.2 Add test class
+
+To add a new test class, add a cases.sh under a sub-directory of
+cases/, and follow the test case class interface definition in section
+2.1. The general result output format should follow that in section
+2.4.

+To verify the result of MCE testing, the MCE record from kernel (via
+/dev/mcelog or panic information) should be compared with reference
+MCE record (for software inject error: the input MCE record). To
+compare MCE record, the following scheme is proposed:
+
+- Define a standard MCE record representation format. It should be
+ human readable, compatible with MCE parser in mce-inject, easy to
+ manipulate in shell (such as remove a field), easy to compare
+ (literally).
+
+ One MCE record is as follow:
+
+ CPU NUMBER
+ BANK NUMBER
+ TSC NUMBER
+ RIP NUMBER
+ ADDR NUMBER
+ MISC NUMBER
+ STATUS NUMBER
+ MCGSTATUS NUMBER
+
+ Multiple MCE records are separated by one empty line.
+
+- Enhance mce-inject or develop a new tool to convert from other
+ format to standard format.
+
+- Develop a new tool based on /usr/sbin/mcelog to output mce-inject
+ compatible MCE record. Because there may be different (uncompatible
+ version) /usr/sbin/mcelog on different machine.
+
+- During verifying, firstly convert various MCE recoards from kernel
+ and reference MCE records to standard format, then compare the
+ standard format MCE records in shell.

+MCE test suite
+---------------
+
+The MCE test suite is a collection of tools and test scripts for
+testing the Linux kernel MCE processing features. The goal is to cover
+most Linux kernel MCE processing code paths and features with
+automation tests.
+
+
+In the Package
+--------------
+
+Here is a short description of what is included in the package
+
+README
+ This document
+COPYING
+ GNU General Public License
+
+Makefile
+ Top level make file for MCE test suite
+
+drivers/*
+
+ Contains test drivers, which drive test procedure and do some
+ common works for test drivers. There is one directory for each
+ test driver, the user interface of a driver is the driver.sh
+ in corresponding directory, such as:
+ drivers/kdump/driver.sh
+ is user interface of kdump test driver.
+
+cases/*
+ Contains all test cases, which may be organized in
+ sub-directories, the interface of a class of test cases is a
+ shell script under cases/, such as:
+ cases/soft-inj/panic/cases.sh
+ is for test cases triggered by soft-inject and my cause system
+ panic during testing.
+
+config/*
+ Contains test configuration files, which specifies the
+ parameters for test driver, which test cases are used in test,
+ the parameters for test cases, etc.
+
+lib/*
+ Contains some shell scripts, in which some common shell
+ functions and variable definitions are defined to be used by
+ multiple test drivers or test cases.
+
+tools/*
+ Some tools used by MCE test suites.
+
+doc/*
+ Documentation for MCE test suites include howto and
+ descriptions of every test case.
+
+results/
+ When test is done, the test result will be placed in this
+ directory, test results for a specific test driver will be
+ placed in corresponding directory, such as test results of
+ kdump test driver will be placed in "results/kdump". General
+ test result is in results/$driver/result; additional results
+ of various cases may be in corresponding directory, for
+ example, files in
+ results/kdump/soft-inj/panic/fatal/
+ is for additional result for test case soft-inj/panic/fatal.
+
+work/
+ During test, some temporary file will be put in work
+ directory, temporary files for a specific test driver will be
+ placed in corresponding directory, such as temporary files of
+ kdump test driver will be placed in "work/kdump". Test log is
+ in work/$driver/log.
+
+bin/
+ Some tools used by test drivers or test cases will be
+ installed into this directory.
+
+Futher Information
+------------------
+
+For futher information about MCE test suite, please refer to documents
+in doc sub-directory.
+
+README.kdump: For testing via kdump. With kdump, a real panic
+ will triggered.

+These are some standalone test programs for various parts of the
+machine check code:
+
+To use ttable and tcases you need to specify a linux source tree
+with the mce improvements patchkit added with make LSRC=/path/to/linux
+or symlink the linux tree to ../linux
+
+The programs requiring kernel sources are not in the all make target.
+If you want to build them use make requireskernel after you
+set up the kernel sources or specified LSRC.
+
+tcases
+
+Simple tester of a few test cases by running the machine check grader code
+in user space. This is an alternative to the more complete coverage
+in the main mce-test test cases.
+
+Doesn't aim to be complete, but more a quick sanity check, that
+can be done without booting a kernel.
+
+ttable
+
+Generate a table of the output of the machine check grader. This gives
+an overview how all the status bits in the machine check architecture
+are processed. Note that a few bits are tested outside the grader
+and this doesn't apply to corrected machine check interrupts.
+
+Use make see to render the output using links -g (note this doesn't work
+with elinks as it is used on many distributions, in this case specify
+a different browser with make BROWSER=browserbinary see)
+
+tinjpage
+
+tinjpage is a coverage test for the hwpoison page recovery code
+in the kernel. It tests different cases by putting pages
+into different stages, triggering poison injection on them
+and verifies the results.
+
+tinjpage requires a kernel with MADV_POISON injection support and the
+hwpoison testkit, but doesn't require a kernel tree and can be built directly with
+make tinjpage
+
+A few of the test cases are timing dependent and might require adjustment
+to run successfully.
+
+tinjpage-working
+
+Old version of tinjpage that tests much less cases, but might be more reliable.
+
+tring
+
+Old unit test program for the ring buffer used in mca recovery.
+Not in default Makefile target.

Please also find the results attached.
Some inconsistencies:
1) GCOV is already built in the booted kernel, still the error message,
2) Absence of /sys/devices/system/machinecheck/ though the
kernel .config suggests that:
CONFIG_X86_MCE=y
# CONFIG_X86_MCE_NONFATAL is not set
CONFIG_X86_MCE_P4THERMAL=y
Is there something i am missing in the setup ?

mce-test needs at least Linux kernel 2.6.31-rc? and some additional
injection related patches from:
http://ftp.kernel.org/pub/linux/kernel/people/yhuang/mce/. We are
working on pushing these additional patches into 2.6.32.

Huang Ying

We do test with mce-test regularly. Do you need our results?
> 2) Comments for and rewriting of this patch for coding styles,
Where can I find the coding style guide for LTP? Are there "indent"
command line for LTP coding style? So we can do some coding style
conversion work automatically.

You can add that to the patch.

Sure. It should be absolutely fine. Wheneven you want to add/update,
just drop in a patch with the set of new results the patch would have
generated.

Can you please then provide this information inside mce-test/README, so
that users are exactly aware of:
1. Which kernel to pick up,
2. Which additional patches to apply,
3. Which config options to set,
before building and running these tests.
Once mainline stable releases are through, you can then again update
mce-test/README with similar information.
I would like people to start doing some testing with your present
mce-test as well. As suggested by Andi, please drop in:
1. a minimal patch which adds the tests(you want) to LTP,
2. update mce-test/README in the same patch with all the above
info,
3. attach test results against the patches you have dropped to ltp,

You are correct. Can you also post all exclusive and elaborate results
of the tests ?

No. we started to follow the Linux Kernel coding style as rectified

I have add these information into the HOWTO in mce-test/doc/howto.txt.
In README, there is a "pointer" to howto.txt in section test
instruction. Is it OK for you?

OK. I will update the document after upstream merging.

OK. I will do this.
I will check the coding style with checkpatch.pl. Do you have other
comments about the code?

I would prefer no wide scale reformattings for now, that will
impact any out of tree patches other people have and the benefits
would seem to be small.
The code is probably not fully compliant, but should be close enough to
kernel style (after all it was written by experienced kernel developers)

Lets see, how much your patch will impact. If necessary, i will make
some changes before check-in. But do remember to provide those info i
had asked for in your patch ;-)

Hi, Subrata,
This is the first version of patch. Please feed back your comments. Test results are attached with the mail too.
Best Regards,
Huang Ying
---------------------------------------------------------->
Integrate MCE test suite into LTP
mce-test is a collection of tools and test scripts for testing the
Linux kernel x86 MCE (Machine Check Exception) processing
features. This patch integrate that into LTP.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+MCE test suite HOWTO
+====================
+
+11 November 2008
+
+Huang Ying
+
+Section 4.2 (Test with kdump test driver) is based on the README of
+LTP kdump test case.
+
+Abstract
+--------
+
+This document explains the structure and design of MCE test suite, the
+kernel patch and user space tools needed for automatic tests, usage
+guide and how to add new test cases into test suite.
+
+0. Quick shortcut
+------------------
+
+- Install the Linux kernel with full MCE injection support, including
+ latest Linux kernel (2.6.31) and MCE injection enhancement patchset
+ in: http://ftp.kernel.org/pub/linux/kernel/people/yhuang/mce/. Make
+ sure following configuration options are enabled:
+
+ CONFIG_X86_MCE=y
+ CONFIG_X86_MCE_INTEL=y
+ CONFIG_X86_MCE_INJECT=y
+
+- Get mcelog git version from
+ git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git.
+ and install in /usr/sbin (or rather first in your $PATH)
+
+ git clone git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git
+ cd mcelog
+ make
+ sudo make install
+
+- Get mce-inject git version from
+ git://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git.
+
+ git clone git://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git
+ cd mce-inject
+ make
+ sudo make install
+
+- Run make test-simple
+ This will do the basic tests, but not the more complicated kdump ones.
+ For more information on those read below.
+
+1. Introduction
+---------------
+
+The MCE test suite is a collection of tools and test scripts for
+testing the Linux kernel MCE processing features. The goal is to cover
+most Linux kernel MCE processing code paths and features with
+automation tests.
+
+If you just want to start testing as quickly as possible, you can skip
+section 2 and section 3, and go section 4.1 directly.
+
+
+2. Structure
+------------
+
+The main intention behind the design is to re-use test cases amongst
+various test methods (represented as test drivers), such as kdump
+based, kernel MCE panic log (tolerant=3) based, etc.
+
+2.1 Test cases
+
+Test cases are grouped into test case classes. The test cases in one
+class share the similar triggering, result collecting and result
+verifying methods. They can be used in same set of test drivers. The
+interface of a test case class is a shell script, usually named as
+cases.sh under a sub-directory of cases/. The following command line
+option should be supported by the test case class shell script:
+
+cases.sh enumerate enumerate test cases in class, print test
+ case names to stdout
+cases.sh trigger trigger the test case
+cases.sh get_result get the result of test case
+cases.sh verify verify the result of test case, and print
+ the verify result to stdout
+
+When execute cases.sh [trigger|get_result|verify], the test case is
+specified via environment variable this_case, which must be one of the
+test case names returned by "cases.sh enumerate".
+
+Other environment variables are also used to pass some information
+from driver to test cases, such as:
+
+this_case name current test case
+driver name of test driver
+klog file name which holds kernel log during test
+KSRC_DIR (for gcov) kernel source code directory
+GCOV (for gcov) gcov collection method
+vmcore (for kdump) vmcore file name
+reboot (for kdump) indicate there is a reboot between test
+ case trigger and test case verify, some
+ context has been gone.
+
+Several test case classes are provided with the test suite. They are
+all based on mce-inject MCE software injection tool, and follows same
+structure.
+
+cases/soft-inj/<class name>/cases.sh Interface of the test case class
+cases/soft-inj/<class name>/data/ Directory contains data file for
+ mce-inject tool.
+cases/soft-inj/<class name>/refer/ Directory contains data file for
+ reference MCE records if necessary.
+
+For document of various test cases, please refer to doc/cases/*.
+
+2.2 Test drivers
+
+Test drivers drive the test procedure, its main structure is a loop
+over test case classes specified in configuration file. For each test
+case class, test driver loops over test cases returned by "cases.sh
+enumerate". And, for each test case, it calls "cases.sh" to trigger,
+get_result and verify the test case. Test driver also do some common
+work for test cases, such as kdump driver collects vmcore file, and
+invoking gcovdump command to get gcov data file.
+
+The interface of test driver is driver.sh, which is usually put in
+drivers/<driver_name>/ directory. The test configuration file should
+be used as the only command line parameter for driver.sh. Test case
+classes should be specified in test configuration file as CASES
+variable, details below.
+
+2.3 Test configuration file
+
+Test configuration file is a shell script to specify parameters for
+test drivers and test cases. It must be put in config/ directory. The
+parameters are represented as shell variables as follow:
+
+CASES Name of test case classes, separate by
+ white space.
+START_BACKGROUND Shell command to start a background process
+ during testing, used for random testing.*
+STOP_BACKGROUND Shell command to stop the background process
+ during testing.
+COREDIR (for kdump) directory contains Linux kernel crash core
+ dump after kdump.
+VMLINUX (for kdump, gcov) vmlinux of Linux kernel
+GCOV (for gcov) Enable GCOV if set none zero.
+KSRC_DIR (for gcov) Kernel source code directory
+
+* To test MCE processing under random environment, a background
+ process can be automatically run simultaneously during MCE
+ testing. The start/stop command is specified via START_BACKGROUND
+ and STOP_BACKGROUND.
+
+2.4 Test result
+
+After test, the general test result will go results/<driver_name>/result.
+The format of general test result is as follow:
+
+<test case name>:
+ Passed: item 1 description
+ Failed: item 2 description
+ ...
+ Passed: item n description
+
+One blank line is used to separate test cases.
+
+Additional test result for various test cases will go
+"results/<driver_name>/<case_name>/<xxx>. For in-package test case
+class, additional test results include:
+
+results/<driver_name>/soft-inject/<case_name>/klog
+ Kernel log during testing
+results/<driver_name>/soft-inject/<case_name>/mcelog
+ mcelog output during testing
+results/<driver_name>/soft-inject/<case_name>/mcelog_refer
+ mcelog output reference
+results/<driver_name>/soft-inject/<case_name>/mce_64.c.gcov (for gcov)
+ gcov output file
+
+
+3. Tools
+--------
+
+3.1 mce-inject
+
+mce-inject is a software MCE injection tool, which is based on Linux
+kernel software MCE injection mechanism. To inject a MCE into Linux
+kernel via mce-inject, a data file should be provided. The syntax is
+similar to the logging output by mcelog with some extensions.
+Please refer to the documentation of mce-inject for more information.
+
+The mce-inject program must be executable in $PATH.
+
+3.2 mcelog
+
+mcelog read /dev/mcelog and prints the stored machine check records to
+stdout. It is used by MCE test suite to verify MCE records generated
+by kernel is same as reference records, at most time, same as input
+records. The current git mcelog version is needed for MCE test suite to
+work properly. Please refer to document of mcelog for more
+information. The latest mcelog can be gotten via git snapshot from
+git://git.kernel.org/pub/scm/utils/cpu/mce/mcelog.git.
+
+Note you need the git version of mcelog available in $PATH.
+
+3.3 gcovdump
+
+gcov is a test coverage tool, the original implementation is used for
+user space program only. LTP (Linux Test Project) provides the kernel
+gcov support. But MCE test involves panic or kdump, so gcovdump is
+developed to dump gcov data from kdump crash dump core. gcovdump has
+been merged by LTP cvs. For more information please refer to gcovdump
+document. The latest gcovdump can be gotten from cvs:
+http://ltp.cvs.sourceforge.net/viewvc/ltp/utils/analysis/gcov-kdump/.
+
+
+4. Usage Guide
+--------------
+
+4.1 Test with simple test driver
+
+4.1.1 Simple test driver
+
+The simple test driver just call cases.sh of test cases one by one in
+a loop. So it is not permitted for test cases to trigger real panic or
+reboot during test. For MCE testing, a special processing mode to just
+log everything in case of MCE is used for the simple test driver, it
+is enabled via set MCE parameter "tolerant=3" during
+testing. "tolerant" can be set via writing:
+ /sys/devices/system/machinecheck/machinecheck0/tolerant
+
+4.1.2 test instruction
+
+The following is the basic test instruction, for some additional
+features such as gcov support, please refer to corresponding
+instructions.
+
+a. Linux kernel and user space tools as follow should be installed
+
+ - A Linux kernel with full MCE injection support (see 0)
+ - mce-inject tool (see 3.1)
+ - mcelog with proper version (see 3.2)
+
+b. Modify config/simple.conf or create a new test configuration
+ file. Refer to section 2.3 for more instruction about test
+ configuration file.
+
+c. Run "make". Carefully check for any errors.
+
+d. To be root and invoke simple test driver on test configuration file
+ as follow
+
+ drivers/simple/driver.sh config/simple.conf
+
+e. General test result will go results/simple/result. Test log will go
+ work/simple/log. Additional test results for various test cases
+ will go results/simple/<test case>/<xxx>. For more details about
+ in-package test case class, please refer to section 2.1.
+
+
+4.2 Test with kdump test driver
+
+4.2.1 kdump test driver
+
+The kdump test driver is based on the kdump test case in Linux Test
+Project, thank LTP for their excellent work!
+
+The kdump driver helps run tests which trigger crash/panic and
+generate result and report via kdump. The test scripts cycle through a
+series of crash/panic scenarios. Each test cycle does the following:
+
+a. Triggers a test case which triggers crash/panic (MCE with tolerant=1).
+b. Kdump kernel boots and saves a vmcore.
+c. System reboots to 1st kernel.
+d. Verifies test case, generate result and report.
+e. After a 1 to 2 minute delay, the next test case is run.
+
+4.2.2 test instruction
+
+Follow the steps to setup kdump test driver.
+
+The test driver is written for SuSE Linux Enterprise Server 10 (and
+onward releases), OpenSUSE, Fedora, Debian, as well as RedHat
+Enterprise Linux 5. Since KDUMP is supported by the above mentioned
+distro's the test driver was written and tested on them. Contribution
+towards supporting more distributions are welcome.
+
+a. Install Linux kernel with full MCE injection and KDUMP support. In
+ addition to MCE injection support in section 0, the following
+ configuration options should be enabled too:
+
+ CONFIG_KEXEC=y
+ CONFIG_CRASH_DUMP=y
+
+b. Install these additional packages:
+
+ For SLES10 or OpenSUSE Distro:
+
+ * kernel-kdump
+ * kernel-source
+ * kexec-tools
+
+ For RHEL5 or Fedora distro:
+
+ * kexec-tools
+ * kernel-devel
+
+c. In addition to bzImage and modules of Linux kernel should be
+ installed on test machine, the vmlinux of Linux kernel should be
+ put on test machine and specified via VMLINUX in test configuration
+ file.
+
+d. Make sure the partition where the test driver is running has space
+ for the tests results and one vmcore file (size of physical
+ memory).
+
+e. Create a new test configuration file or use a existing one in
+ config/, such as kdump.conf. Note: not all test case classes can be
+ used with kdump test driver, see "important points" below.
+
+f. Run "make". Carefully check for any errors.
+
+g. To be root and run "drivers/kdump/driver.sh <conf>"
+
+h. After test is done, the test log of the last run of kdump driver will
+ be displayed on main console.
+
+Few Important points to remember:
+
+- kdump test driver request that a real panic should be triggered when
+ test case is triggered. So not all test case classes can be used
+ with kdump test driver, for example, all test case classes for
+ corrected MCE can not be used with kdump test driver.
+
+- If you need to stop the tests before all test cases have run, run
+ "crontab -r" and "killall driver.sh" within 1 minute after the 1st
+ kernel reboots. Then, if you'd like to carry on tests from that point
+ on, run:
+ rm work/kdump/stamps/setupped
+ drivers/kdump/driver.sh <conf>
+ If you'd like to start tests from the beginning, run:
+ make reset
+ drivers/kdump/driver.sh <conf>
+
+- If a failure occurs when booting the kdump kernel, you'll need to
+ manually reset the system so it reboots back to the 1st kernel and
+ continues on to the next test. For this reason, it's best to monitor
+ the tests from a console. If possible, setup a serial console (not a
+ must, any type of console setup will do). If using minicom, enable
+ saving of kernel messages displayed on minicom into a file, by
+ pressing ctrl+a+l on the console. Else, when it is observed that the
+ kdump kernel has failed to boot, manually copy the boot message into
+ a file to enable the debugging the cause of the hang.
+
+- The results are saved in results/kdump/result, which also shows
+ where you are in the test run. When the "Test run complete" entry
+ appears in that file, you're done. Verbose log can be found at
+ work/log.
+
+- The test machine would be unavailable for any other work during the
+ period of the test run.
+
+4.3 Gcov support
+
+Gcov is a test coverage tool. It can be used to discover untested
+parts of program, collect branch taken statistics to optimize program,
+etc. In MCE test suite, it is used to get test coverage, that is,
+which C statements are covered by each test case.
+
+Gcov support is optional, if you don't care about test coverage
+information, just skip this section.
+
+a. Make sure your kernel has gcov support. You can find lasted kernel
+ gcov patches from:
+ http://ltp.sourceforge.net/coverage/gcov.php
+
+ A README for kernel gcov can be found from:
+ http://ltp.sourceforge.net/coverage/gcov/readme.php
+
+ Notes: CONFIG_GCOV_ALL does not work for me. Add the line
+ EXTRA_CFLAGS += $(KBUILD_GCOV_FLAGS)
+ to the respective Makefiles are more stable. For example, this line
+ can be added into "linux/arch/x86/kernel/cpu/mcheck/Makefile"
+
+b. If you want to use gcov with kdump test driver, please install
+ gcovdump tool(see section 3.4). The latest gcovdump can be gotten
+ from cvs:
+ http://ltp.cvs.sourceforge.net/viewvc/ltp/utils/analysis/gcov-kdump/.
+
+c. Linux kernel source source code should be put on the test
+ machine. Its root directory should be specified in test
+ configuration file via KSRC_DIR.
+
+d. In addition to bzImage and modules of Linux kernel should be
+ installed on test machine, the vmlinux of Linux kernel should be
+ put on test machine and specified via VMLINUX of test configuration
+ file.
+
+e. Make sure gcov is available in your test system. It comes with gcc
+ package normally. If kdump test driver is used, a tool named
+ gcovdump is also needed to dump *.gcda from crash dump image.
+
+f. In test configuration file, make sure the following setting is
+ available:
+
+ # enable GCOV support
+ GCOV=1
+ # kernel source is needed to get gcov graph
+ KSRC_DIR=<kernel source directory>
+ VMLINUX=<vmlinux>
+
+g. After testing, *.c.gcov will be generated in test case result
+ directory, such as
+ results/kdump/soft-inj/non-panic/corrected/mce_64.c.gcov.
+
+h. To merge gcov graph data from several test cases, a tool named
+ gcov_merge.py in tools sub-directory can be used. For example,
+
+ tools/gcov_merge results/kdump/soft-inj/*/*/mce_64.c.gcov
+
+ Will output merged gcov graph from all test cases under
+ soft-inj. This can be used to check coverage of several test cases.
+
+4.4 tool
+
+Some tools are provided to help analyze test result.
+
+- tools/grep_result.sh
+
+ Grep from general test result (results/<driver_name>/result) in
+ terms of test case instead of line, because the result of one test
+ case may span several line.
+
+ Usage:
+ cat results/<driver_name>/result | tools/grep_result.sh <grep options>
+
+ Where <grep options> are same as options available to /bin/grep.
+
+
+5. Add test cases
+-----------------
+
+5.1 Add test case to in-package test class
+
+All in-package test classes use mce-inject software injection tool and
+follows same structure. The steps to add a new test case is as follow:
+
+a. Find an appropriate test case class to add your test case.
+
+b. Add a new mce-inject data file into to cases/soft-inj/<class name>/data/.
+
+c. If the reference mcelog is different from mce-inject input data
+ file, put that reference file into cases/soft-inj/<class_name>/refer/.
+
+d. In cases/soft-inj/<class name>/cases.sh, there are shell commands
+ "case" in shell functions get_result() and verify(). Add a branch
+ in each shell command "case" for your test case.
+
+5.2 Add test class
+
+To add a new test class, add a cases.sh under a sub-directory of
+cases/, and follow the test case class interface definition in section
+2.1. The general result output format should follow that in section
+2.4.

+To verify the result of MCE testing, the MCE record from kernel (via
+/dev/mcelog or panic information) should be compared with reference
+MCE record (for software inject error: the input MCE record). To
+compare MCE record, the following scheme is proposed:
+
+- Define a standard MCE record representation format. It should be
+ human readable, compatible with MCE parser in mce-inject, easy to
+ manipulate in shell (such as remove a field), easy to compare
+ (literally).
+
+ One MCE record is as follow:
+
+ CPU NUMBER
+ BANK NUMBER
+ TSC NUMBER
+ RIP NUMBER
+ ADDR NUMBER
+ MISC NUMBER
+ STATUS NUMBER
+ MCGSTATUS NUMBER
+
+ Multiple MCE records are separated by one empty line.
+
+- Enhance mce-inject or develop a new tool to convert from other
+ format to standard format.
+
+- Develop a new tool based on /usr/sbin/mcelog to output mce-inject
+ compatible MCE record. Because there may be different (uncompatible
+ version) /usr/sbin/mcelog on different machine.
+
+- During verifying, firstly convert various MCE recoards from kernel
+ and reference MCE records to standard format, then compare the
+ standard format MCE records in shell.

+MCE test suite
+---------------
+
+The MCE test suite is a collection of tools and test scripts for
+testing the Linux kernel MCE processing features. The goal is to cover
+most Linux kernel MCE processing code paths and features with
+automation tests.
+
+
+In the Package
+--------------
+
+Here is a short description of what is included in the package
+
+README
+ This document
+
+COPYING
+ GNU General Public License
+
+Makefile
+ Top level make file for MCE test suite
+
+drivers/*
+ Contains test drivers, which drive test procedure and do some
+ common works for test drivers. There is one directory for each
+ test driver, the user interface of a driver is the driver.sh
+ in corresponding directory, such as:
+ drivers/kdump/driver.sh
+ is user interface of kdump test driver.
+
+cases/*
+ Contains all test cases, which may be organized in
+ sub-directories, the interface of a class of test cases is a
+ shell script under cases/, such as:
+ cases/soft-inj/panic/cases.sh
+ is for test cases triggered by soft-inject and my cause system
+ panic during testing.
+
+config/*
+ Contains test configuration files, which specifies the
+ parameters for test driver, which test cases are used in test,
+ the parameters for test cases, etc.
+
+tsrc/*
+ Some standalone test programs for various parts of the machine
+ check code.
+
+lib/*
+ Contains some shell scripts, in which some common shell
+ functions and variable definitions are defined to be used by
+ multiple test drivers or test cases.
+
+tools/*
+ Some tools used by MCE test suites.
+
+doc/*
+ Documentation for MCE test suites include howto and
+ descriptions of every test case.
+
+results/
+ When test is done, the test result will be placed in this
+ directory, test results for a specific test driver will be
+ placed in corresponding directory, such as test results of
+ kdump test driver will be placed in "results/kdump". General
+ test result is in results/$driver/result; additional results
+ of various cases may be in corresponding directory, for
+ example, files in
+ results/kdump/soft-inj/panic/fatal/
+ is for additional result for test case soft-inj/panic/fatal.
+
+work/
+ During test, some temporary file will be put in work
+ directory, temporary files for a specific test driver will be
+ placed in corresponding directory, such as temporary files of
+ kdump test driver will be placed in "work/kdump". Test log is
+ in work/$driver/log.
+
+bin/
+ Some tools used by test drivers or test cases will be
+ installed into this directory.
+
+
+Test Instruction
+----------------
+
+Please refer to corresponding section in doc/howto.txt.
+
+
+Futher Information
+------------------
+
+For futher information about MCE test suite, please refer to documents
+in doc sub-directory.
+
+doc/howto.txt: a more detailed HOWTO document
+
+doc/cases/*.txt: Description of every test case, including test
+ objective, code patch tested, reference and
+ expected results

+These are some standalone test programs for various parts of the
+machine check code:
+
+To use ttable and tcases you need to specify a linux source tree
+with the mce improvements patchkit added with make LSRC=/path/to/linux
+or symlink the linux tree to ../linux
+
+The programs requiring kernel sources are not in the all make target.
+If you want to build them use make requireskernel after you
+set up the kernel sources or specified LSRC.
+
+tcases
+
+Simple tester of a few test cases by running the machine check grader code
+in user space. This is an alternative to the more complete coverage
+in the main mce-test test cases.
+
+Doesn't aim to be complete, but more a quick sanity check, that
+can be done without booting a kernel.
+
+ttable
+
+Generate a table of the output of the machine check grader. This gives
+an overview how all the status bits in the machine check architecture
+are processed. Note that a few bits are tested outside the grader
+and this doesn't apply to corrected machine check interrupts.
+
+Use make see to render the output using links -g (note this doesn't work
+with elinks as it is used on many distributions, in this case specify
+a different browser with make BROWSER=browserbinary see)
+
+tinjpage
+
+tinjpage is a coverage test for the hwpoison page recovery code
+in the kernel. It tests different cases by putting pages
+into different stages, triggering poison injection on them
+and verifies the results.
+
+tinjpage requires a kernel with MADV_POISON injection support and the
+hwpoison testkit, but doesn't require a kernel tree and can be built directly with
+make tinjpage
+
+A few of the test cases are timing dependent and might require adjustment
+to run successfully.
+
+tinjpage-working
+
+Old version of tinjpage that tests much less cases, but might be more reliable.
+
+tring
+
+Old unit test program for the ring buffer used in mca recovery.
+Not in default Makefile target.
