From f9dc1ebc0d5cc475b8729f2dc4f6dac8c83e52a1 Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Thu, 7 Mar 2019 04:42:49 +0000 Subject: [PATCH] panfrost: Determine framebuffer format bits late Again, these formats are only properly known at the time of fragment job emit. Rather than hardcoding the format, at least for MFBD we begin to construct the format bits on-demand. This cleans up the code, futureproofs for ES3 framebuffer formats, and should fix bugs regarding FBO colour swizzles.
