Subject: drm/amd/display: Add Handling for gfxversion DcGfxBase
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2e193f5b1b4f638b47a177a6b4686cbb5cf75065;p=thirdparty%2Flinux.git

drm/amd/display: Add Handling for gfxversion DcGfxBase

[Why]
There is no way to set tiling in dml in the case that gfxversion is
DcGfxBase.

[How]
Where tiling is updated based on Gfx, add case for DcGfxBase and set
tiling to dml2_sw_linear.
