Subject: [PATCH V10 00/28] Add new powerpc specific ELF core notes
Date: Tue, 16 Feb 2016 14:29:30 +0530	[thread overview]
Message-ID: <1455613198-5113-1-git-send-email-khandual@linux.vnet.ibm.com> (raw)

	This patch series adds twelve new ELF core note sections which can
be used with existing ptrace request PTRACE_GETREGSET-SETREGSET for accessing
various transactional memory and other miscellaneous debug register sets on
powerpc platform.

Test Result (All tests pass on both BE and LE)
----------------------------------------------
ptrace-ebb		PASS
ptrace-gpr		PASS
ptrace-tm-gpr		PASS
ptrace-tm-spd-gpr	PASS
ptrace-tar		PASS
ptrace-tm-tar		PASS
ptrace-tm-spd-tar	PASS
ptrace-vsx		PASS

Changes in V10:
---------------
- Rebased against the latest mainline
- Fixed couple of build failures in the test cases related to aux vector

Changes in V9:
--------------
- Fixed static build check failure after tm_orig_msr got dropped
- Fixed asm volatile construct for used registers set
- Fixed EBB, VSX, VMX tests for LE
- Fixed TAR test which was failing because of system calls
- Added checks for PPC_FEATURE2_HTM aux feature in the tests
- Fixed copyright statements

Changes in V8:
--------------
- Split the misc register set into individual ELF core notes
- Implemented support for VSX register set (on and off TM)
- Implemented support for EBB register set
- Implemented review comments on previous versions
- Some code re-arrangements, re-writes and documentation
- Added comprehensive list of test cases into selftests

Changes in V7:
--------------
- Fixed a config directive in the MISC code
- Merged the two gitignore patches into a single one

Changes in V6:
--------------
- Added two git ignore patches for powerpc selftests
- Re-formatted all in-code function definitions in kernel-doc format

Changes in V5:
--------------
- Changed flush_tmregs_to_thread, so not to take into account self tracing
- Dropped the 3rd patch in the series which had merged two functions
- Fixed one build problem for the misc debug register patch
- Accommodated almost all the review comments from Suka on the 6th patch
- Minor changes to the self test program
- Changed commit messages for some of the patches

Changes in V4:
--------------
- Added one test program into the powerpc selftest bucket in this regard
- Split the 2nd patch in the previous series into four different patches
- Accommodated most of the review comments on the previous patch series
- Added a patch to merge functions __switch_to_tm and tm_reclaim_task

Changes in V3:
--------------
- Added two new error paths in every TM related get/set functions when regset
  support is not present on the system (ENODEV) or when the process does not
  have any transaction active (ENODATA) in the context
- Installed the active hooks for all the newly added regset core note types

Changes in V2:
--------------
- Removed all the power specific ptrace requests corresponding to new NT_PPC_*
  elf core note types. Now all the register sets can be accessed from ptrace
  through PTRACE_GETREGSET/PTRACE_SETREGSET using the individual NT_PPC* core
  note type instead
- Fixed couple of attribute values for REGSET_TM_CGPR register set
- Renamed flush_tmreg_to_thread as flush_tmregs_to_thread
- Fixed 32 bit checkpointed GPR support
- Changed commit messages accordingly
