Subject: [PATCH] tests/intel/xe_vm: Always have at least 2 pages bound in hammer sections
Date: Tue, 9 Apr 2024 18:15:42 -0700 [thread overview]
Message-ID: <20240410011542.409087-1-matthew.brost@intel.com> (raw)
If the prefetch buffer is 2k or larger the hammer sections will prefetch
the next page, if the page is unbound a fault will occur. Account for
larger prefetchs by always having at least 2 pages bound for the hammer
thread.
