From 5563872dbfbf733ed56e1b367bc8944ca59b1c3e Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 9 Aug 2017 11:31:48 -0700 Subject: [PATCH] isl: Validate row pitch of stencil surfaces. Also, silence an obnoxious finishme that started occurring for all GL applications which use stencil after the i965 ISL conversion. v2: Check against 3DSTATE_STENCIL_BUFFER's pitch bits when using separate stencil, and 3DSTATE_DEPTH_BUFFER's bits when using combined depth-stencil.
