From: Alyssa Rosenzweig Date: Fri, 21 Aug 2020 20:22:10 +0000 (-0400) Subject: panfrost: Use pack for blit shaders X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5b3b2a6697900191ed86057373253c6bea9a83bc;p=mesa.git panfrost: Use pack for blit shaders This is quite a bit cleaner, I think, and validates the XML in preparation for moving over the main driver.
