Cover-letter for V2 of the series is at https://lists.ozlabs.org/pipermail/linuxppc-dev/2016-January/138054.html Changes in V3: Addressed review comments from Michael Neuling - Made commit message in 4/9 better reflect the patch - Removed overuse of #ifdef blocks and redundant condition in 5/9 - Split 6/8 in two to better prepare for 7,8,9 - Removed #ifdefs in 6/9 Changes in V4: - Addressed non ABI compliant ASM macros in 1/9 - Fixed build breakage due to changing #ifdefs in V3 (6/9) - Reordered some conditions in if statements Changes in V5: - Enchanced basic-asm.h to provide ABI independent macro as pointed out by Naveen Rao. - Tested for both BE and LE builds. Had to disable -flto from the selftests/powerpc Makefile as it didn't play well with the custom ASM. - Added some extra debugging output to the vmx_signal testcase - Fixed comments in testing code - Updated VSX test code to use GCC Altivec macros Cyril Bur (9): selftests/powerpc: Test the preservation of FPU and VMX regs across syscall selftests/powerpc: Test preservation of FPU and VMX regs across preemption selftests/powerpc: Test FPU and VMX regs in signal ucontext powerpc: Explicitly disable math features when copying thread powerpc: Restore FPU/VEC/VSX if previously used powerpc: Prepare for splitting giveup_{fpu,altivec,vsx} in two powerpc: Add the ability to save FPU without giving it up powerpc: Add the ability to save Altivec without giving it up powerpc: Add the ability to save VSX without giving it up arch/powerpc/include/asm/processor.h | 2 + arch/powerpc/include/asm/reg.h | 8 + arch/powerpc/include/asm/switch_to.h | 13 +- arch/powerpc/kernel/asm-offsets.c | 2 + arch/powerpc/kernel/entry_64.S | 21 +- arch/powerpc/kernel/fpu.S | 25 +-- arch/powerpc/kernel/ppc_ksyms.c | 4 - arch/powerpc/kernel/process.c | 168 +++++++++++++-- arch/powerpc/kernel/vector.S | 45 +--- tools/testing/selftests/powerpc/Makefile | 3 +- tools/testing/selftests/powerpc/basic_asm.h | 62 ++++++ tools/testing/selftests/powerpc/math/.gitignore | 6 + tools/testing/selftests/powerpc/math/Makefile | 21 ++ tools/testing/selftests/powerpc/math/fpu_asm.S | 197 +++++++++++++++++ tools/testing/selftests/powerpc/math/fpu_preempt.c | 113 ++++++++++ tools/testing/selftests/powerpc/math/fpu_signal.c | 135 ++++++++++++ tools/testing/selftests/powerpc/math/fpu_syscall.c | 90 ++++++++ tools/testing/selftests/powerpc/math/vmx_asm.S | 234 +++++++++++++++++++++ tools/testing/selftests/powerpc/math/vmx_preempt.c | 112 ++++++++++ tools/testing/selftests/powerpc/math/vmx_signal.c | 156 ++++++++++++++ tools/testing/selftests/powerpc/math/vmx_syscall.c | 91 ++++++++ 21 files changed, 1425 insertions(+), 83 deletions(-) create mode 100644 tools/testing/selftests/powerpc/basic_asm.h create mode 100644 tools/testing/selftests/powerpc/math/.gitignore create mode 100644 tools/testing/selftests/powerpc/math/Makefile create mode 100644 tools/testing/selftests/powerpc/math/fpu_asm.S create mode 100644 tools/testing/selftests/powerpc/math/fpu_preempt.c create mode 100644 tools/testing/selftests/powerpc/math/fpu_signal.c create mode 100644 tools/testing/selftests/powerpc/math/fpu_syscall.c create mode 100644 tools/testing/selftests/powerpc/math/vmx_asm.S create mode 100644 tools/testing/selftests/powerpc/math/vmx_preempt.c create mode 100644 tools/testing/selftests/powerpc/math/vmx_signal.c create mode 100644 tools/testing/selftests/powerpc/math/vmx_syscall.c -- 2.7.1 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
