Subject: [PATCH] drm/nouveau/fb/gp102-: cache scrubber binary on first load
References: bsc#1012628
Patch-mainline: 6.2.7
Git-commit: 1b9b4f922f96108da3bb5d87b2d603f5dfbc5650
[ Upstream commit 1b9b4f922f96108da3bb5d87b2d603f5dfbc5650 ]
During system shutdown nouveau might not be able to request firmware from
Userspace, which then leads to a regression preventing the system from
shutting down.
Cache the scrubber binary for this case.
Fixes: 0e44c21708761 ("drm/nouveau/flcn: new code to load+boot simple HS FWs (VPR scrubber)")
