[PATCH v2 08/11] drm/amd/display: Move FPU associated DCN30 code to DML folder
Qingqing Zhuo
qingqing.zhuo at amd.com
Fri May 13 21:16:48 UTC 2022
From: Jasdeep Dhillon <jdhillon at amd.com>
[why & how]
As part of the FPU isolation work documented in
https://patchwork.freedesktop.org/series/93042/, isolate
code that uses FPU in DCN30 to DML, where all FPU code
should locate.
