Copy the dma-can-stall property into the fwspec structure.
Can't we just handle this as a regular device property? It's not part of the
actual IOMMU specifier, it doesn't need to be translated in any way, and
AFAICS it's used a grand total of once, in a slow path. Simply treating it
as the per-device property that it is should require zero additional code
for DT, and a simple device_add_properties() call for IORT.
TBH that appears to be true of pasid-num-bits as well.
Right I think that's better, thanks for the pointer. I'll take care of
pasid-num-bits too. The Huawei quirk (fake PCIe supporting stall) is a
little worse this way, but it should work.
Thanks Jean, I tested the following diff, it works with Huawei quirk.
Thanks
