[PATCH v3 03/44] drm/nouveau/gr/gf100-: lose contents of global ctxbufs across suspend

From: Lyude Paul
Date: Tue Sep 19 2023 - 18:06:13 EST


From: Ben Skeggs <bskeggs@xxxxxxxxxx>

Some of these buffers are quite large, and there's no need to preserve
them across suspend.

Mark the contents as lost to speedup suspend/resume.
