selftests/rseq: Revert "selftests/rseq: Add mm_numa_cid to test script"

2023-01-12T10:22:22+00:00

The mm_numa_cid related rseq patches from the series were not picked up into the tip tree, so enabling the mm_numa_cid test needs to be reverted. This reverts commit b344b8f2d88dbf095caf97ac57fd3645843fa70f.

selftests/rseq: Implement parametrized mm_cid test

2022-12-27T11:52:15+00:00

Adapt to the rseq.h API changes introduced by commits "selftests/rseq: : Template memory ordering and percpu access mode". Build a new param_test_mm_cid, param_test_mm_cid_benchmark, and param_test_mm_cid_compare_twice executables to test the new "mm_cid" rseq field.

rseq/selftests: Test MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ

2020-09-25T12:23:27+00:00

Based on Google-internal RSEQ work done by Paul Turner and Andrew Hunter. This patch adds a selftest for MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ. The test quite often fails without the previous patch in this patchset, but consistently passes with it.

rseq/selftests: Adapt number of threads to the number of detected cpus

2019-04-08T22:44:21+00:00

On smaller systems, running a test with 200 threads can take a long time on machines with smaller number of CPUs. Detect the number of online cpus at test runtime, and multiply that by 6 to have 6 rseq threads per cpu preempting each other.

rseq/selftests: Provide Makefile, scripts, gitignore

2018-06-06T09:58:35+00:00

A run_param_test.sh script runs many variants of the parametrizable tests. Wire up the rseq Makefile, add directory entry into MAINTAINERS file.
