| 2024-11-07 | selftests/powerpc: Give all tests 2 minutes timeout | Michael Ellerman | |
| 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.

| 2024-05-17 | Merge tag 'powerpc-6.10-1' of ↵ | Linus Torvalds | |
| git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: - Enable BPF Kernel Functions (kfuncs) in the powerpc BPF JIT. - Allow per-process DEXCR (Dynamic Execution Control Register) settings via prctl, notably NPHIE which controls hashst/hashchk for ROP protection. - Install powerpc selftests in sub-directories. Note this changes the way run_kselftest.sh needs to be invoked for powerpc selftests. - Change fadump (Firmware Assisted Dump) to better handle memory add/remove. - Add support for passing additional parameters to the fadump kernel. - Add support for updating the kdump image on CPU/memory add/remove events. - Other small features, cleanups and fixes.

| 2024-04-29 | selftests/powerpc: make sub-folders buildable on their own | Madhavan Srinivasan | |
| 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 <maddy@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20240229093711.581230-3-maddy@linux.ibm.com | |||
| 2024-04-12 | selftests/powerpc/papr-vpd: Fix missing variable initialization | Nathan Lynch | |
| The "close handle without consuming VPD" testcase has inconsistent results because it fails to initialize the location code object it passes to ioctl() to create a VPD handle. Initialize the location code to the empty string as intended.

| 2024-02-05 | selftests/powerpc/papr_vpd: Check devfd before get_system_loc_code() | R Nageswara Sastry | |
| Calling get_system_loc_code before checking devfd and errno fails the test when the device is not available, the expected behaviour is a SKIP. Change the order of 'SKIP_IF_MSG' to correctly SKIP when the /dev/ papr-vpd device is not available. Test output before: Test FAILED on line 271 Test output after: [SKIP] Test skipped on line 266: /dev/papr-vpd not present Signed-off-by: R Nageswara Sastry <rnsastry@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20240131130859.14968-1-rnsastry@linux.ibm.com | |||
| 2023-12-13 | powerpc/selftests: Add test for papr-vpd | Nathan Lynch | |
| Add selftests for /dev/papr-vpd, exercising the common expected use cases: * Retrieve all VPD by passing an empty location code. * Retrieve the "system VPD" by passing a location code derived from DT root node properties, as done by the vpdupdate command. The tests also verify that certain intended properties of the driver hold: * Passing an unterminated location code to PAPR_VPD_CREATE_HANDLE gets EINVAL. * Passing a NULL location code pointer to PAPR_VPD_CREATE_HANDLE gets EFAULT. * Closing the device node without first issuing a PAPR_VPD_CREATE_HANDLE command to it succeeds. * Releasing a handle without first consuming any data from it succeeds. * Re-reading the contents of a handle returns the same data as the first time. Some minimal validation of the returned data is performed. The tests are skipped on systems where the papr-vpd driver does not initialize, making this useful only on PowerVM LPARs at this point.
