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 Original V1: ------------ - Posted here at https://patchwork.ozlabs.org/patch/418583/ Anshuman Khandual (12): powerpc: Fix handling of DSCR related facility unavailable exception powerpc, process: Remove the unused extern dscr_default powerpc, offset: Change PACA_DSCR to PACA_DSCR_DEFAULT powerpc, dscr: Added some in-code documentation documentation, powerpc: Add documentation for DSCR support selftests, powerpc: Add test for system wide DSCR default selftests, powerpc: Add test for explicitly changing DSCR value selftests, powerpc: Add test for DSCR SPR numbers selftests, powerpc: Add test for DSCR value inheritence across fork selftests, powerpc: Add test for DSCR inheritence across fork & exec selftests, powerpc: Add test for all DSCR sysfs interfaces selftests, powerpc: Add thread based stress test for DSCR sysfs interfaces Documentation/powerpc/00-INDEX | 2 + Documentation/powerpc/dscr.txt | 83 ++++++++++++++ arch/powerpc/include/asm/processor.h | 9 ++ arch/powerpc/kernel/asm-offsets.c | 2 +- arch/powerpc/kernel/entry_64.S | 2 +- arch/powerpc/kernel/process.c | 2 - arch/powerpc/kernel/sysfs.c | 38 +++++++ arch/powerpc/kernel/tm.S | 4 +- arch/powerpc/kernel/traps.c | 45 +++++++- arch/powerpc/kvm/book3s_hv_rmhandlers.S | 2 +- tools/testing/selftests/powerpc/Makefile | 2 +- tools/testing/selftests/powerpc/dscr/Makefile | 19 ++++ tools/testing/selftests/powerpc/dscr/dscr.h | 120 ++++++++++++++++++++ .../selftests/powerpc/dscr/dscr_default_test.c | 121 +++++++++++++++++++++ .../selftests/powerpc/dscr/dscr_explicit_test.c | 72 ++++++++++++ .../powerpc/dscr/dscr_inherit_exec_test.c | 118 ++++++++++++++++++++ .../selftests/powerpc/dscr/dscr_inherit_test.c | 96 ++++++++++++++++ .../selftests/powerpc/dscr/dscr_sysfs_test.c | 89 +++++++++++++++ .../powerpc/dscr/dscr_sysfs_thread_test.c | 114 +++++++++++++++++++ .../selftests/powerpc/dscr/dscr_user_test.c | 62 +++++++++++ 20 files changed, 989 insertions(+), 13 deletions(-) create mode 100644 Documentation/powerpc/dscr.txt create mode 100644 tools/testing/selftests/powerpc/dscr/Makefile create mode 100644 tools/testing/selftests/powerpc/dscr/dscr.h create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_default_test.c create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_explicit_test.c create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_inherit_exec_test.c create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_inherit_test.c create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_sysfs_test.c create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_sysfs_thread_test.c create mode 100644 tools/testing/selftests/powerpc/dscr/dscr_user_test.c -- 1.9.3
