[PATCH 1/1] drm/amdkfd: Use real device for messages

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

 



kfd_chardev() doesn't provide much useful information in dev_... messages
on multi-GPU systems because there is only one KFD device, which doesn't
correspond to any particular GPU. Use the actual GPU device to indicate
the GPU that caused a message.
