From 323c91250682ac931941047f282a613c74b1ba26 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Tue, 15 Sep 2015 01:32:40 -0400 Subject: nv50,nvc0: detect underlying resource changes and update tic When updating texture buffers, we might end up replacing the whole buffer. Check that the tic address matches the resource address, and if not, update the tic and reupload it.
