Another issue with the Apple T2 based 2018 controllers seem to be that they blow up (and shut the machine down) if there's a tag collision between the IO queue and the Admin queue. My suspicion is that they use our tags for their internal tracking and don't mix them with the queue id. They also seem to not like when tags go beyond the IO queue depth, ie 128 tags. This adds a quirk that marks tags 0..31 of the IO queue reserved Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Reviewed-by: Ming Lei <ming.lei@redhat.com> Acked-by: Keith Busch <keith.busch@intel.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> |
