Subject: VKMS: New plane formats
Date: Wed, 1 Sep 2021 17:19:03 -0300	[thread overview]
Message-ID: <d1ceaa32-e143-8d3c-4bfb-7b31673cc76c@gmail.com> (raw)

Hi,

I'm working to add new plane formats to vkms. But I don't know what 
should be the behavior in the situation that we received multiple planes 
with different formats from the users-space.

For example, if the user chooses:
- DRM_FORMAT_ARGB16161616 to the primary plane
- DRM_FORMAT_ARGB8888 to the cursor
- DRM_FORMAT_YUV42 to the overlay

What should be the output format that will be used to calculate the crc? 
DRM_FORMAT_ARGB16161616?

My idea was to convert all the planes to the primary, but I'm not sure 
if it is the right approach.

Best regards,
---
