From: Simon Guo <wei.guo.simon@xxxxxxxxx> This selftest suite is for PPC register ptrace functionality. It is also useful for Transaction Memory functionality verification.

The same for other TM instructions. - Correct while(ptr); loop without memory barrier. - Remove an invalid checking on TEXASR in tm-spd-spr.c. - Use FAIL_IF() as possible to indicate failure line conveniently. - Consolidate some asm code on GPR/FPR load/save into reg.h/reg.S - rebased to recent ppc git tree. Changes in V14: --------------- - Remove duplicated NT_PPC_xxx register macro in tools/testing/selftests/powerpc/ptrace/ptrace.h - Clean some coding style warning Changes in V13: --------------- - Remove Cc lines from changelog - Add more Signed-off-by lines of Simon Guo Changes in V12: --------------- - Revert change which is trying to incoporate following patch: [PATCH 3/5] powerpc: tm: Always use fp_state and vr_state to store live registers - Release share memory resource in all self test cases - Optimize tfhar usage in ptrace-tm-spr.c Changes in V11: --------------- - Rework based on following patch: [PATCH 3/5] powerpc: tm: Always use fp_state and vr_state to store live registers - Split EBB/PMU register ptrace implementation. - Clean some coding style warning - Added more shared memory based sync between parent and child during TM tests - Re worded some of the commit messages and cleaned them up - selftests/powerpc/ebb/reg.h has already moved as selftests/powerpc/reg.h Dropped the previous patch doing the same thing - Combined the definitions of SPRN_DSCR from dscr/ test cases - Fixed dscr/ test cases for new SPRN_DSCR_PRIV definition available 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 ------------- Anshuman Khandual
