Re: [PATCH] doc: gpu: Add document describing buffer exchange

stride ????

I think what's clear is:

- Per-plane property - In bytes - Offset between two consecutive rows

How that applies to weird YUV formats is the tricky question…

Btw. there was a fun argument whether the same modifier value could mean different things on different devices. There were also arguments that a certain modifier could reference additional implicit memory on the device - memory that can only be accessed by very specific devices.

I think AMLOGIC_FBC_LAYOUT_SCATTER was one of those.

A recent exmaple of this is [1].
