Subject: [PATCH i-g-t 0/2] gem_wsim: fix batch premature completion
Date: Tue, 28 Jul 2026 12:26:57 +0200 [thread overview]
Message-ID: <20260728102659.316861-1-marcin.bernatowicz@linux.intel.com> (raw)
Fixes sporadic batch premature termination after sustained GPU workload
stress testing by hardening ticks_delta initialization/re-arming:
- initialize ticks_delta to ~0u in xe_spin
- reset ticks_delta to ~0u before fixed-duration batch submission
in gem_wsim
Marcin Bernatowicz (2):
lib/xe/xe_spin: initialize ticks_delta to ~0u
benchmarks/gem_wsim: re-arm ticks_delta before batch submission
