Hi Evan, Thank you for sending the patch over! A small nitpick: the subject line could just say: Add quirk for AMD Navi 14 to disable ATS support Or something along these lines, as I am not sure how useful the ID and revision are in the subject, especially since the commit message explains in details what hardware is affected, etc. > 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. As this might be a candidate for a back-port to current stable and long-term kernels, does it have any "Fixes" tag we could include here for reference? If not, then it's OK. > Change-Id: I3d9d570bd473762e3bfbb251cf8abaf5af38ced9 I assume this is from some code review service like Gerrit? We usually as people to drop these when sending patches to be included in the kernel (so when sending patches upstream). Krzysztof
