[Intel-xe] [PATCH 03/10] drm/xe/oa: Add registers and GPU commands used by OA

Ashutosh Dixit ashutosh.dixit at intel.com
Tue Aug 8 01:31:52 UTC 2023


Add registers and GPU commands used by OA in subsequent patches. The xe oa
code programs OA units which generate performance data. The code also
submits command buffers to change hardware engine context images and
implement waits.
