Subject: [igt-dev] [PATCH i-g-t 2/3] lib/igt_kms: Add igt_reduce_format()
Date: Thu, 30 Jan 2020 17:12:28 +0200	[thread overview]
Message-ID: <20200130151229.984-2-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200130151229.984-1-ville.syrjala@linux.intel.com>

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

Add a helper to reduce a pixel format to a "base" format.
Ie. group all formats to some idea of classes based on the
bits per pixel + component sizes etc. ignoring any component ordering.
Let's us skip potentially redundant tests when all we might care
about is testing each format "class" the once.
