From a651bc027d5ed4150bb5240fc9f46a6ca569f665 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 11 Mar 2016 21:26:31 -0500 Subject: [PATCH] nvc0: fix blit triangle size to fully cover FB's > 8192x8192 The idea is that a single triangle will cover the whole area being drawn, allowing the blit shader to do its work. However the max fb size is 16384x16384, which means that the triangle we draw needs to be twice that in order to cover the whole area fully. Increase the size of the triangle to 32768x32768. This fixes a number of dEQP tests that were failing because a blit was involved which would miss some of the resulting texture.
