[PATCH 0/2] ARM SMMUv3 StreamID Implementation

Posted by Nabih Estefan 9 months, 1 week ago

This patch series modifies the ARM SMMUv3 to be able to work with an
implementation specific StreamID that does not match exactly the PCIe BDF.
The way to achieve this is by converting the smmu_get_sid and smmu_iommu_mr
functions to virtual functions that can be overridden by inheritance, making
sure the StreamID is consistently 32 bits and removing the hardcoding of the
SMMU_IDR1.SIDSIZE to 16 bits.

Roque Arcudia Hernandez (2):
  hw/arm/smmuv3: Check StreamIDs against SMMU_IDR1.SIDSIZE value
  hw/arm/smmu-common: Create virtual function for implementation defined
    StreamID
