Subject: [PATCH] Add RGBA64 texture cpp for vc4 driver.
Date: Wed, 31 Oct 2018 21:42:27 -0700	[thread overview]
Message-ID: <20181101044227.5517-1-nick.kreeger@gmail.com> (raw)

This patch is needed to help implement half-float texturing and
rendering for the vc4 driver in mesa. This small patch introduces the
cpp value for the RGBA64 texture. A future patch will include updates to
vc4_render_cl.c to handle HDR color stores.
