Subject: [PATCH 3/3] drm/nouveau/pci: SOR crossbar quirk for 10b0:1b81
Date: Mon, 5 Feb 2018 02:22:56 +0100 [thread overview]
Message-ID: <20180205012256.2198-3-danilokrummrich@dk-develop.de> (raw)
In-Reply-To: <20180205012256.2198-1-danilokrummrich@dk-develop.de>
On Gainward GTX 1070 routing any other SOR than SOR-1 to macro link
'G' (outp index 7) causes failures:
[ 6.712111] nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 61c880 [ IBUS ]
[ 6.724888] nouveau 0000:01:00.0: disp: intr24 80000000
[ 8.716668] nouveau 0000:01:00.0: DRM: base-0: timeout
[ 10.716679] nouveau 0000:01:00.0: DRM: base-1: timeout
[ 63.511862] nouveau 0000:01:00.0: DRM: EVO timeout
As I'm not able to spot an issue in the driver, I suppose it's
firmware related.
Therefore to work around this issue skip crossbar routing for this
particular macro link and instead use identity mapping.
