From d4aed002145bb9c4d8bf9a80af3e9f3198c421fa Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Wed, 12 Jun 2019 15:23:19 -0700 Subject: [PATCH] panfrost/mfbd: Handle rendering to linear mipmap In anticipation of more general mipmapping support, we implemented support for rendering to linear mipmaps (a very simple case).
