Subject: [PATCH v3 i-g-t 0/1] tests/intel/xe_compute_preempt: Compute preemption check
Date: Wed, 10 Sep 2025 17:19:58 +0000 [thread overview]
Message-ID: <20250910171959.1852534-1-sobin.thomas@intel.com> (raw)
On platforms like PVC that lack walker mid-thread preemption, running
tests in forked threads can cause inconsistent states due to mid-
execution igt_skip calls. This patch adds a kernel preemption check
at the start of each subtest to ensure consistent behavior. If the
GPU lacks required preemption, the test is skipped gracefully.
v2: Moved compatibility check to igt_fixture per review.
v3: - Added thread group preemption and WMTP checks;
- Introduced enum flags for preemption types. [Zbigniew]
