The patch looks good to me. I'd wait for John to approve it as well.
Reviewed-by: Felix Kuehling <felix.kuehl...@amd.com>
John, if the patch looks good to you, please feel free to apply it to
amd-staging-drm-next in your time zone. We're in a hurry because this
fix is needed in the next ROCm release. If you believe reporting a fake
MEC2 version would cause problems for graphics, an alternative fix would
be to change kfd_gws_init to check the mec_fw_version on Arcturus.
Regards,
Felix
