Subject: [Intel-gfx] [PATCH 0/1] drm/i915/gt: Initialize reserved and unspecified MOCS indices
Date: Tue, 23 Jun 2020 10:29:56 +0530 [thread overview]
Message-ID: <20200623045957.1649059-1-ayaz.siddiqui@intel.com> (raw)
In order to avoid functional breakage of mis-programmed applications that
have grown to depend on unused MOCS entries, we are programming
those entries to be equal to fully cached ("L3 + LLC") entry.
These reserved and unspecified entries should not be used as they may be
changed to less performant variants with better coherency in the future
if more entries are needed.
I made some mistake in header of patch,Correcting that may leads to a
new entry in patchwork. Please follow
https://patchwork.freedesktop.org/patch/368699/?series=78012&rev=1
to get details of that discussion.
