Subject: [PATCH 3/3] drm/i915: Add format modifiers for Intel
Date: Tue,  2 May 2017 22:14:28 -0700	[thread overview]
Message-ID: <20170503051428.4734-3-ben@bwidawsk.net> (raw)
In-Reply-To: <20170503051428.4734-1-ben@bwidawsk.net>

This was based on a patch originally by Kristian. It has been modified
pretty heavily to use the new callbacks from the previous patch.

v2:
  - Add LINEAR and Yf modifiers to list (Ville)
  - Combine i8xx and i965 into one list of formats (Ville)
  - Allow 1010102 formats for Y/Yf tiled (Ville)

v3:
  - Handle cursor formats (Ville)
  - Put handling for LINEAR in the mod_support functions (Ville)

v4:
  - List each modifier explicitly in supported modifiers (Ville)
  - Handle the CURSOR plane (Ville)

v5:
  - Split out cursor and sprite handling (Ville)
