Hm, where do we have the canonical source for all these fourcc codes? I'm
asking since we have our own copy in the kernel as drm_fourcc.h, and that
one is part of the userspace ABI since we use it to pass around
framebuffer formats and format lists.
Just afraid to create long-term maintainance madness here with the
kernel's iron thou-shalt-not-break-userspace-ever rule ... Not likely
we'll ever accept srgb for framebuffers though.

Well, I wasn't ever in favour of using fourcc codes since they're just not standardized at all, highly redundant in some cases and also miss lots of stuff we actually need (like all the rgb formats). I also argued against them, but some people wanted them for whatever reason. And since I didn't want to argue for several years about the subject, I just gave in and made the drm pixel formats fourcss. But given that I just pulled the fourccs out of my ass, we can't really cross use them between different subsystems anyway. So if we just consider all the different fourcc namespaces totally distinct, we're not going to have any problems. Personally I can promise that I will _not_ be checking Mesa/whatever code for conflicting fourccs when I need to add a new one to drm_fourcc.h. There, now I've given fair warning and if things explode later it won't be my fault. However if someone wants to emulate the drm fourcc style for whatever reason, there is a distinct pattern how I cooked them up. Well, a few different patterns depending whether it's RGB,YUV,packed,planar etc. Cc'ing the heck out of this to get kernel people to hopefully notice. Maybe someone takes charge of this ...

[Mesa-dev] [PATCH] dri3, i915, i965: Add __DRI_IMAGE_FOURCC_SARGB8888
The __DRIimage createImageFromFds function takes a fourcc code, but there was
no fourcc code that match __DRI_IMAGE_FORMAT_SARGB8. This adds a define for
that format, adds a translation in DRI3 from __DRI_IMAGE_FORMAT_SARGB8 to
__DRI_IMAGE_FOURCC_SARGB and then adds translations *back* to
__IMAGE_FORMAT_SARGB8 in both the i915 and i965 drivers.
I'll refrain from comments on whether I think having two separate sets of
format defines in dri_interface.h is a good idea or not...
