[Intel-gfx] [PATCH 0/8] Adding NV12 support for BXT display

[Vidya Srinivas]

This patch series is adding NV12 support for Broxton display after
rebasing on latest drm-intel-nightly. Initial series of the patches
can be found here:
https://lists.freedesktop.org/archives/intel-gfx/2015-May/066786.html

Feature has been currently tested with custom linux based test tool
IGT test development is under progress. Floating these patches for
initial review. These NV12 patches are dependent on Ville's patches
mentioned below.

Update from last rev:
Patches were initial reviewed last when floated but
currently there was a design change with respect to
- the way fb offset is handled
- the way rotation is handled
Rebase of the current NV12 patch series has been done as per the
current changes on drm-intel-nightly.

  drm/i915: Set scaler mode for NV12
  drm/i915: Update format_is_yuv() to include NV12
  drm/i915: Upscale scaler max scale for NV12
  drm/i915: Add NV12 as supported format for primary plane
  drm/i915: Add NV12 as supported format for sprite plane
  drm/i915: Add NV12 support to intel_framebuffer_init

Ville Syrjälä (2):
  drm/i915: Implement .get_format_info() hook for CCS
  SKL+ display engine can scan out certain kinds of compressed surfaces
    produced by the render engine. This involved telling the display
    engine the location of the color control surfae (CCS) which
    describes which parts of the main surface are compressed and which
    are not. The location of CCS is provided by userspace as just
    another plane with its own offset.
