Starting subtest: buffer-size
Starting dynamic subtest: rcs-0-256K
(xe_oa:4458) CRITICAL: Test assertion failure function
test_non_zero_reason, file ../tests/intel/xe_oa.c:2509:
(xe_oa:4458) CRITICAL: Failed assertion: !(oa_status &
DRM_XE_OASTATUS_BUFFER_OVERFLOW)
Dynamic subtest rcs-0-256K failed.
