[PATCH] drm/amdgpu: Re-enable FRU check for most models v3

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

 



There are 2 VG20 SKUs that do not have the FRU on there, and trying to read
that will cause a hang. For now, check for the gaming SKU until a proper
fix can be implemented. This re-enables serial number reporting for
server cards

v2: Add ASIC check
v3: Don't default to true for pre-VG10
