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.

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 (15): selftests/powerpc: Add more SPR numbers, TM & VMX instructions to 'reg.h' selftests/powerpc: Use the new SPRN_DSCR_PRIV definiton selftests/powerpc: Add ptrace tests for EBB selftests/powerpc: Add ptrace tests for GPR/FPR registers selftests/powerpc: Add ptrace tests for GPR/FPR registers in TM selftests/powerpc: Add ptrace tests for GPR/FPR registers in suspended TM selftests/powerpc: Add ptrace tests for TAR, PPR, DSCR registers selftests/powerpc: Add ptrace tests for TAR, PPR, DSCR in TM selftests/powerpc: Add ptrace tests for TAR, PPR, DSCR in suspended TM selftests/powerpc: Add ptrace tests for VSX, VMX registers selftests/powerpc: Add ptrace tests for VSX, VMX registers in TM selftests/powerpc: Add ptrace tests for VSX, VMX registers in suspended TM selftests/powerpc: Add ptrace tests for TM SPR registers selftests/powerpc: Add .gitignore file for ptrace executables selftests/powerpc: Fix a build issue tools/testing/selftests/powerpc/Makefile | 3 +- .../selftests/powerpc/context_switch/cp_abort.c | 6 +- tools/testing/selftests/powerpc/dscr/dscr.h | 10 +- tools/testing/selftests/powerpc/ptrace/.gitignore | 11 + tools/testing/selftests/powerpc/ptrace/Makefile | 13 + .../testing/selftests/powerpc/ptrace/ptrace-ebb.c | 188 +++++ .../testing/selftests/powerpc/ptrace/ptrace-ebb.h | 99 +++ .../testing/selftests/powerpc/ptrace/ptrace-gpr.c | 196 ++++++ .../testing/selftests/powerpc/ptrace/ptrace-gpr.h | 74 ++ .../testing/selftests/powerpc/ptrace/ptrace-tar.c | 159 +++++ .../testing/selftests/powerpc/ptrace/ptrace-tar.h | 50 ++ .../selftests/powerpc/ptrace/ptrace-tm-gpr.c | 296 ++++++++ .../selftests/powerpc/ptrace/ptrace-tm-spd-gpr.c | 324 +++++++++ .../selftests/powerpc/ptrace/ptrace-tm-spd-tar.c | 195 ++++++ .../selftests/powerpc/ptrace/ptrace-tm-spd-vsx.c | 219 ++++++ .../selftests/powerpc/ptrace/ptrace-tm-spr.c | 186 +++++ .../selftests/powerpc/ptrace/ptrace-tm-tar.c | 182 +++++ .../selftests/powerpc/ptrace/ptrace-tm-vsx.c | 206 ++++++ .../testing/selftests/powerpc/ptrace/ptrace-vsx.c | 140 ++++ .../testing/selftests/powerpc/ptrace/ptrace-vsx.h | 127 ++++ tools/testing/selftests/powerpc/ptrace/ptrace.S | 396 +++++++++++ tools/testing/selftests/powerpc/ptrace/ptrace.h | 771 +++++++++++++++++++++ tools/testing/selftests/powerpc/reg.h | 42 +- 23 files changed, 3880 insertions(+), 13 deletions(-) create mode 100644 tools/testing/selftests/powerpc/ptrace/.gitignore create mode 100644 tools/testing/selftests/powerpc/ptrace/Makefile create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-ebb.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-ebb.h create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-gpr.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-gpr.h create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tar.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tar.h create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-gpr.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-spd-gpr.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-spd-tar.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-spd-vsx.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-spr.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-tar.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-tm-vsx.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-vsx.c create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace-vsx.h create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace.S create mode 100644 tools/testing/selftests/powerpc/ptrace/ptrace.h -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
