[v4,0/5] Support alpha blending in MTK display driver

Message

Hsiao Chien Sung via B4 Relay July 17, 2024, 5:24 a.m. UTC

Support "Pre-multiplied" and "None" blend mode on MediaTek's chips by
adding correct blend mode property when the planes init.
Before this patch, only the "Coverage" mode (default) is supported.

For the whole series, applied to mediatek-drm-next [1], thanks.

I am seeing broken colors on an MT8173 Chromebook with next-20240912,
which goes away if I git-revert this series (commits 1f66fe62cc09
eb17c5909481 a3f7f7ef4bfe 59e9d9de25f0 4225d5d5e779).

To illustrate, I took a picture [1] of some color mixing diagrams from
Wikipedia [2]. Do you have an idea of what goes wrong?

(I'm busy with too many things so I don't want to debug it now...)

Hi, Jason:

Please help to fix this issue.
Otherwise, I would revert this series.

Thank you for your feedback. I apologize for the delay in my response;
I was just notified of your email by my colleague.

Based on the provided pictures, it appears that this issue is related
to the way the MT8173 chip handles alpha channel (ARGB -> RGBA), which
differes from the behavior of later chips.

We will either submit a new fix ASAP or revert this series as a first
step.

Hi Alper,

I think that's a platform issue because it works find in my MT8188
platform, but I don't have any MT8173 platform.

Can you help me test the fix patch in your MT8173 platform?
I'll provide a fix patch in 2 weeks via Google Chat.

Regards,
Jason-JH.Lin

I replied over Google Chat, but to make it clear for others on the
mailing list: Yes, I'll try to test patches when you send them.

Jason, Two weeks is a bit too late as CK already picked your series: reverting
and reapplying creates noise in the commit log, and when this can be avoided it
should be avoided.

Since upstream is broken, please understand that this fix should be developed
with *highest* priority (so, as immediate as possible).

Thanks,
Angelo
