d7228a58 - selftests/powerpc/dexcr: Add -no-pie to hashchk tests

Wed, 17 Apr 2024 11:23:17 +0000

selftests/powerpc/dexcr: Add -no-pie to hashchk testsThe hashchk tests want to verify that the hash key is changed over exec.It does so by calculating hashes at the same address across an exec.This is made simpler by disabling PIE functionality, so we canre-execute ourselves and be using the same addresses in the child.While -fno-pie is already added, -no-pie is also required.Fixes: bdb07f35a52f ("selftests/powerpc/dexcr: Add hashst/hashchk test")Signed-off-by: Benjamin Gray Signed-off-by: Michael Ellerman Link: https://msgid.link/20240417112325.728010-2-bgray@linux.ibm.com List of files: /linux-6.15/tools/testing/selftests/powerpc/dexcr/Makefile

108e5e68 - selftests/powerpc: make sub-folders buildable on their own

Thu, 29 Feb 2024 09:37:11 +0000

selftests/powerpc: make sub-folders buildable on their ownBuild breaks when executing make with run_tests for sub-foldersunder powerpc. This is because, CFLAGS and GIT_VERSION macros aredefined in Makefile of toplevel powerpc folder. make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/mm' gcc hugetlb_vs_thp_test.c ../harness.c ../utils.c -o /home/maddy/selftest_output//hugetlb_vs_thp_test hugetlb_vs_thp_test.c:6:10: fatal error: utils.h: No such file or directory 6 | #include "utils.h" | ^~~~~~~~~ compilation terminated.Fix this by adding the flags.mk in each sub-folder Makefile. Also removethe CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile sincethe same is definied in flags.mkSigned-off-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Link: https://msgid.link/20240229093711.581230-3-maddy@linux.ibm.com List of files: /linux-6.15/tools/testing/selftests/powerpc/dexcr/Makefile

Mon, 19 Jun 2023 07:36:28 +0000

selftests/powerpc/dexcr: Add DEXCR status utility lsdexcrAdd a utility 'lsdexcr' to print the current DEXCR status. Useful forquickly checking the status such as when debugging test failures orverifying the new default DEXCR does what you want (for userspace atleast). Example output: # ./lsdexcr uDEXCR: 04000000 (NPHIE) HDEXCR: 00000000 Effective: 04000000 (NPHIE) SBHE (0): clear (Speculative branch hint enable) IBRTPD (3): clear (Indirect branch recurrent target ...)
