I'm interested if that counts.

I asked the same question on the DRM_FORMAT_XYUV thread, do we need to
wait for userspace to get new fourcc merged.


I'd say yes. Why would otherwise clutter headers which affect what other 
guys are doing for different drivers?


If it makes any difference for you I made KMS video output plug-in for 
VLC media player as part of my enablement of P01x formats. My plug-in 
didn't make it to any VLC release yet but you can find it in VLC master 
branch. Through my plug-in you can ask any fourcc for setting up KMS 
planes, then you'll need to find which VLC fourcc matches your KMS plane 
and tell VLC about it on commandline. If you have driver implementation 
of P010 format which I saw earlier in your patch you can compile VLC 
with P010 included in DRM headers and then you'll be able to watch 
videos using your new format. For P01x formats recompile is needed as 
their setup is different from other formats, packed formats should work 
without anything special.

Hi Alex,

For my patches there seems limited interest to get them merged before 
IGT support these modes..I'm not holding my breath for this.
