intel-iommu: Yet another BIOS workaround: Isoch DMAR unit with no TLB space
Asus decided to ship a BIOS which configures sound DMA to go via the dedicated IOMMU unit, but assigns precisely zero TLB entries to that unit. Which causes the whole thing to deadlock, including the DMA traffic on the _other_ IOMMU units. Nice one. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
