From: Brad Love <redacted> [ Upstream commit 5f864cfbf59bfed2057bd214ce7fbf6ad420d54b ] The folowing AMD IOMMU are affected by the RiSC engine stall, requiring a reset to maintain continual operation. After being added to the broken_dev_id list the systems are functional long term. 0x1481 is the PCI ID for the IOMMU found on Starship/Matisse 0x1419 is the PCI ID for the IOMMU found on 15h (Models 10h-1fh) family 0x5a23 is the PCI ID for the IOMMU found on RD890S/RD990 Signed-off-by: Brad Love <redacted> Signed-off-by: Hans Verkuil <redacted> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org> --- drivers/media/pci/cx23885/cx23885-core.c | 9 +++++++++ 1 file changed, 9 insertions(+)
