Subject: [PATCH i-g-t 4/4] tests/kms_color: New test for pipe level color management
Date: Mon,  1 Feb 2016 15:34:52 +0000	[thread overview]
Message-ID: <1454340892-21408-5-git-send-email-lionel.g.landwerlin@intel.com> (raw)
In-Reply-To: <1454340892-21408-1-git-send-email-lionel.g.landwerlin@intel.com>

This test enables testing of :

     * degamma LUTs
     * csc matrix
     * gamma LUTs
     * legacy gamma LUTs

v2: turn assert into require to skip on platform not supporting color
    management

v3: add invalid blob ids tests
