From 21c863a695bfcb3c19ee1e1c84ecab67f49553eb Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Mon, 1 Jul 2019 09:44:40 -0700 Subject: [PATCH] panfrost/mfbd: Include codes for float framebuffers We see the hardware doesn't actually support float framebuffers in the native sense -- rather, it just allows higher bpp framebuffers and lets a blend shader / additional clear_color fields sort out the formats. This will be.. interesting.
