Subject: [PATCH] nouveau: check gsp->rm as well as gsp pointer before gcx ready
Date: Thu, 1 Oct 2026 07:21:51 +1000 [thread overview]
Message-ID: <20260930212151.3926202-1-airlied@gmail.com> (raw)
From: Dave Airlie <airlied@redhat.com>
In turing systems where gsp exists, but can end up not being used,
we need to add a second check.
Fixes: cb4c7603678c ("drm/nouveau/gsp/r570: Add support for INTERNAL_GCX_ENTRY_PREREQUISITE")
