Hi Zhenneng,
+ some display folks
First of all, thanks a lot for your patch.
We had a similar patch in the past, but we had to revert it because we
cannot simply enable DCN for ARM-based systems. You can refer to this
commit message to get a better context:
https://gitlab.freedesktop.org/agd5f/linux/-/commit/c241ed2f0ea549c18cff62a3708b43846b84dae3
Before enabling ARM, we first need to isolate all FPU code in the DML
folder fully. You can read more about our strategy at the below link:
https://patchwork.freedesktop.org/series/93042/
And you can see some examples of this effort in the below links:
- https://patchwork.freedesktop.org/series/95504/
- https://patchwork.freedesktop.org/patch/455465/?series=94441&rev=3
- https://patchwork.freedesktop.org/series/98247/
Soon we will submit another series that isolate DCN302, but we still
need to isolate code from DCN20, DCN10, DCN303, and DCN301.
If you want to help us speed up this process, feel free to look at
DCN301 or DCN10.
Best Regards
Siqueira
