selftests/powerpc: Give all tests 2 minutes timeout

2024-11-07T11:36:30+00:00

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/ptrace: Convert to load/store doubles

2022-07-25T02:05:16+00:00

Some of the ptrace tests check the contents of floating pointer registers. Currently these use float, which is always 4 bytes, but the ptrace API supports saving/restoring 8 bytes per register, so switch to using doubles to exercise the code more fully.
