[PATCH] dri: Rework planar image interface

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As discussed with Kristian on #wayland. Pushes the decision of components
into the dri driver giving it greater freedom to allow t to implement YUV
samplers in hardware, and which mode to use.

This interface will also allow drivers like SVGA to implement YUV surfaces
without the need to sub-allocate and instead send 3 seperate buffers
for each channel, currently not implemented.

This is only the dri interface and gallium dri state tracker parts of the
changes needed to make this change work, I haven't done the intel parts
of them and I'll do these tomorrow or monday, I wanted to get the dri-
interface changes out as fast as possible for review.

I have tested these changes on SVGA with the previus patch series I sent
out (mines the last one), and everything seem to work just as before.

Cheers, Jakob.
