Subject: [igt-dev] [PATCH 4/4] xe_vm: Add mmap / munmap sections that split large pages
Date: Wed, 15 Mar 2023 19:32:50 -0700 [thread overview]
Message-ID: <20230316023250.4115730-5-matthew.brost@intel.com> (raw)
In-Reply-To: <20230316023250.4115730-1-matthew.brost@intel.com>
Splitting large pages involves using dma-resv slots for ordering, make
sure this works.
