drm/xe/xe2: Enable Priority Mem Read
Enable feature to allow memory reads to take a
priority memory path. This will reduce latency
on the read path, but may introduce read after
write (RAW) hazards as read and writes will no
longer be ordered.
To avoid RAW hazards, SW can use the MI_MEM_FENCE
command or any other MI command that generates
non posted memory writes. This will ensure data
is coherent in memory prior to execution of
commands which read data from memory.
No pattern identified in KMD that could lead to a
hazard.
v2: Modify commit message, enable priority mem
read feature for media, modify version range,
modify bspec detail (Matt Roper)
