From 00d4315d37ec736fccfee50a402fa2a929054bde Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Thu, 7 Jul 2016 23:46:28 -0400 Subject: [PATCH] st/mesa: return appropriate mesa format for ETC texture formats MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Even when the backend driver does not support ETC formats, we handle the decoding into an uncompressed backing texture. However as far as core mesa is concerned, it's an ETC texture and we should return the relevant ETC mesa format. This condition can get hit when using glTexStorage to create the texture object.
