+
+From: Evan Quan <evan.quan@amd.com>
+
+commit e8946a53e2a698c148b3b3ed732f43c7747fbeb6 upstream
+
+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:

+  45beb31d3afb ("PCI: Mark AMD Navi10 GPU rev 0x00 ATS as broken")
+  5e89cd303e3a ("PCI: Mark AMD Navi14 GPU rev 0xc5 ATS as broken")
