Subject: [PATCH V2 00/12] POWER DSCR fixes, improvements, docs and tests
Date: Tue, 13 Jan 2015 15:52:28 +0530 [thread overview]
Message-ID: <1421144560-15901-1-git-send-email-khandual@linux.vnet.ibm.com> (raw)
This patch series has patches for POWER DSCR fixes, improvements,
in code documentaion, kernel support user documentation and selftest based
test cases. It has got five test cases which are derived from Anton's DSCR
test bucket which can be listed as follows.
(1) http://ozlabs.org/~anton/junkcode/dscr_default_test.c
(2) http://ozlabs.org/~anton/junkcode/dscr_explicit_test.c
(3) http://ozlabs.org/~anton/junkcode/dscr_inherit_exec_test.c
(4) http://ozlabs.org/~anton/junkcode/dscr_inherit_test.c
(5) http://ozlabs.org/~anton/junkcode/user_dscr_test.c
So the derivied test cases have Anton's copyright along with mine but the
commit message as of now has only my signed-off-by statement. As Anton
mentioned before he would put his signed-off-by after reviewing these
modified test cases.
NOTE1: Anton's original inherit exec test expected the child to have system
default DSCR value instead of the inherited DSCR value from it's parent.
But looks like thats not the case when we execute the test, it always
inherits it's parent's DSCR value over the exec call as well. So I have
changed the test program assuming its correct to have the inherited DSCR
value in the fork/execed child program. Please let me know if thats not
correct and I am missing something there.
NOTE2: The selftests/powerpc/.gitignore will be added and will get updated
through a different patch series related to ptrace instead of this one.
Changes in V2:
-------------
- Updated the thread struct DSCR value inside mtspr facility exception path
- Modified the in code documentation to follow the kernel-doc format
- Added seven selftest based DSCR related test cases under powerpc
