From 90e2e96ea37745ae18a1ff7b322e3321731828e4 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 15 Jan 2020 15:07:56 +0100 Subject: [PATCH] drm/nouveau/gr/gp10b: Use gp100_grctx and gp100_gr_zbc gp10b doesn't have all the registers that gp102_gr_zbc wants to access, which causes IBUS MMIO faults to occur. Avoid this by using the gp100 variants of grctx and gr_zbc.
