Subject: Re: [PATCH 2/2] drm/nouveau: prevent NULL deref of gr in GETPARAM_GRAPH_UNITS
Date: Fri, 2 Oct 2026 14:18:32 -0300 [thread overview]
Message-ID: <20261002171838.282505-1-Capitain_Jack@yahoo.com> (raw)
In-Reply-To: <20260812-nouveau-nvkm-absent-subdev-null-deref-v1-2-7e057f6aeba0@gmail.com>
Hi Zhenhao,
Tested on an RTX 3060 (GA106) under nouveau without
firmware-nvidia-gsp, kernel 7.3-rc1.
Together with Jim Cromie's GET_ZCULL_INFO fix, this removes the second
oops (nvkm_gr_units+0x9) that kills kwin_wayland when NVK starts.
KWin then composites, and NVK refuses the device cleanly.
Details in my reply to Jim's patch.
Tested-by: Daniel Campos Ramos <Capitain_Jack@yahoo.com>
