[PATCH 07/21] drm/amd/display: move FPU associated DCN303 code to DML folder

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Dhillon, Jasdeep" <Jasdeep.Dhillon@xxxxxxx>

[Why & How]
As part of the FPU isolation work documented in
https://patchwork.freedesktop.org/series/93042/, isolate
code that uses FPU in DCN303 to DML, where all FPU code
should locate.
