From 8b43f4201129a5d11ebf314f9ae612289fd0994e Mon Sep 17 00:00:00 2001 From: Tapani Pälli Date: Thu, 5 Jan 2017 13:40:35 +0200 Subject: i965: call intel_prepare_render always when reading pixels MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently we do this only in the fallback code (when tiled memcpy version failed) but it needs to be done always so that we have correct read and write buffer in place. No regressions seen in CI.
