[Intel-gfx] [PATCH 0/5] drm/i915; Support for COLOR_ENCODING and COLOR_RANGE props

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

While reviewing the COLOR_ENCODING/COLOR_RANGE props I decided that I
might as well implement them in i915. And here is the result.

With this the user can now select between BT.601 vs. BT.709, and
limited vs. full range on every platform where we currently have
YCbCr framebuffer support. I had to fix up GLK a bit more since it
wasn't actually doing the YCbCr->RGB conversion at all.

In order to unblock this further I also hacked together some userspace
support in the form of the XV_COLORSPACE port attribute in the intel
ddx. For that I needed to hack off the atomic requirement for these
properties. I don't think there's much point in restricting these 
to atomic anyway.

I've pushed the entire series (including Jyri's stuff with my hack) here:
git://github.com/vsyrjala/linux.git color_encoding_prop

And the intel ddx xv stuff is available here:
git://github.com/vsyrjala/xf86-video-intel.git xv_colorspace
