Subject: [PATCH] PCI: Mark AMD Navi14 GPU ATS as broken
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Observed unexpected GPU hang during runpm stress test on 0x7341 rev 0x00. Further debugging shows broken ATS is related.

Disable ATS on this part. Similar issues on other devices:

a2da5d8cc0b0 ("PCI: Mark AMD Raven iGPU ATS as broken in some platforms") 45beb31d3afb ("PCI: Mark AMD Navi10 GPU rev 0x00 ATS as broken") 5e89cd303e3a ("PCI: Mark AMD Navi14 GPU rev 0xc5 ATS as broken")
