linux-toradex.git/kernel/irq/refcount_interrupt_test.c, branch master Linux kernel for Apalis and Colibri modules irq: Add max local_interrupt_disable() nesting level kunit test case 2026-10-02T09:47:14+00:00 Boqun Feng boqun@kernel.org 2026-10-01T08:25:19+00:00 67e0eadd862616cb22145d6117b79b79c4ae48fe To confirm the max nesting level of local_interrupt_disable() works, a kunit test is added to the whole test suite. Note that when DEBUG_PREEMPT=y, it'll generate a warning which is expected.

To confirm the max nesting level of local_interrupt_disable() works, a
kunit test is added to the whole test suite.

Note that when DEBUG_PREEMPT=y, it'll generate a warning which is
expected.

irq: Add KUnit test for refcounted interrupt enable/disable 2026-08-10T08:50:18+00:00 Lyude Paul lyude@redhat.com 2026-08-04T16:14:28+00:00 07a88e2bcd5b5bd7881b2e12b6aad1897a7ee1de While making changes to the refcounted interrupt patch series, at some point on my local branch I broke something and ended up writing some kunit tests for testing refcounted interrupts as a result. So, let's include these tests now that we have refcounted interrupts.
