selftests/verification: Add selftests for deadline and stall monitors

2026-07-31T14:27:46+00:00

Add selftests to verify deadline monitors don't fail under expected conditions and the stall monitor report violations only when expected. Reviewed-by: Nam Cao Link: https://lore.kernel.org/r/20260723074534.43521-18-gmonaco@redhat.com Signed-off-by: Gabriele Monaco

selftests/verification: Rearrange the wwnr_printk test

2026-07-31T14:27:46+00:00

The wwnr_printk test expects no reactions in some situations, after fixing the bash assertion, the test is failing because expecting no reaction after a previous step had reactions is flaky without making sure all buffers are flushed. Wait for reactions to be over when expected by polling dmesg for an interval without any rv message. Also simplify the load function to stop loads as soon as a reaction occurs, this limits the number of lines to flush and makes tests overall faster and more stable.

selftests/verification: Fix wrong errexit assumption

2026-07-31T14:27:46+00:00

RV selftest rely on bash errexit (set -e) to terminate with error, when a step is expected to return false, the following syntax is used: ! cmd This however prevents the test from exiting when cmd is false (desired) but doesn't exit if cmd is true, since commands prefixed with ! are explicitly excluded from errexit. Use the syntax ! cmd || false Which ends up checking the exit value of ! cmd and supplies a false command for errexit to evaluate.

selftests/verification: Add initial RV tests

2025-11-11T12:18:55+00:00

Add a series of tests to validate the RV tracefs API and basic functionality. * available monitors: Check that all monitors (from the monitors folder) appear as available and have a description. Works with nested monitors. * enable/disable: Enable and disable all monitors and validate both the enabled file and the enabled_monitors. Check that enabling container monitors enables all nested monitors. * reactors: Set all reactors and validate the setting, also for nested monitors. * wwnr with printk: wwnr is broken on purpose, run it with a load and check that the printk reactor works. Also validate disabling reacting_on or monitoring_on prevents reactions. These tests use the ftracetest suite.
