Subject: [igt-dev] [PATCH i-g-t 8/9] lib/igt_fb: Speed up format conversion for local memory
Date: Wed, 29 Jan 2020 20:16:00 +0200 [thread overview]
Message-ID: <20200129181601.15918-8-imre.deak@intel.com> (raw)
In-Reply-To: <20200129181601.15918-1-imre.deak@intel.com>
To speed up the conversion that needs to read from a dGFX local memory
use the same trick as what's used for GTT apertures and make a copy
first into system memory.
