[PATCH V3] PCI: Add quirk for AMD Navi14 to disable ATS support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Unexpected GPU hang was observed during runpm stress test
on 0x7341 rev 0x00. Further debugging shows broken ATS is
related. Thus as a followup of commit 5e89cd303e3a ("PCI:
Mark AMD Navi14 GPU rev 0xc5 ATS as broken"), we disable
the ATS for the specific SKU also.
