selftests/powerpc: Give all tests 2 minutes timeout

2024-11-07T11:36:30Z

Each of the powerpc selftests runs with a timeout of 2 minutes by default (see tools/testing/selftests/powerpc/harness.c). But when tests are run with run_kselftest.sh it uses a timeout of 45 seconds, meaning some tests run OK standalone but fail when run with the test runner. So tell run_kselftest.sh to give each test 130 seconds, that should allow the tests to complete, or be killed by the powerpc test harness after 2 minutes. If for some reason the harness fails, or for the few tests that don't use the harness, the 130 second timeout should catch them if they get stuck.

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

2024-04-29T13:54:42Z

Build breaks when executing make with run_tests for sub-folders under powerpc. This is because, CFLAGS and GIT_VERSION macros are defined 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 remove the CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile since the same is definied in flags.mk Signed-off-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Link: https://msgid.link/20240229093711.581230-3-maddy@linux.ibm.com

selftests/powerpc: Re-order *FLAGS to follow lib.mk

2024-04-29T13:51:16Z

In some powerpc/ sub-folder Makefiles, CFLAGS are defined before lib.mk include. Clean it up by re-ordering the flags to follow after the mk include. This is needed to support sub-folders in powerpc/ buildable on its own.

powerpc/pseries: Move mm/book3s64/vphn.c under platforms/pseries/

2019-07-04T12:23:38Z

hcall_vphn() is specific to pseries and will be used in a subsequent patch. So, move it to a more appropriate place under arch/powerpc/platforms/pseries. Also merge vphn.h into lppaca.h and update vphn selftest to use the new files. Signed-off-by: Naveen N. Rao Signed-off-by: Michael Ellerman

selftests/powerpc: Fix Makefiles for headers_install change

2018-09-28T05:07:45Z

Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") introduced a requirement that Makefiles more than one level below the selftests directory need to define top_srcdir, but it didn't update any of the powerpc Makefiles. This broke building all the powerpc selftests with eg: make[1]: Entering directory '/src/linux/tools/testing/selftests/powerpc' BUILD_TARGET=/src/linux/tools/testing/selftests/powerpc/alignment; mkdir -p $BUILD_TARGET; make OUTPUT=$BUILD_TARGET -k -C alignment all make[2]: Entering directory '/src/linux/tools/testing/selftests/powerpc/alignment' ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make[2]: *** No rule to make target '../../../../scripts/subarch.include'. make[2]: Failed to remake makefile '../../../../scripts/subarch.include'. Makefile:38: recipe for target 'alignment' failed Fix it by setting top_srcdir in the affected Makefiles.
