Jean-Philippe Brucker 87f42391f6 iommu/arm-smmu-v3: Add support for Substream IDs ... At the moment, the SMMUv3 driver implements only one stage-1 or stage-2 page directory per device. However SMMUv3 allows more than one address space for some devices, by providing multiple stage-1 page directories. In addition to the Stream ID (SID), that identifies a device, we can now have Substream IDs (SSID) identifying an address space. In PCIe, SID is called Requester ID (RID) and SSID is called Process Address-Space ID (PASID). A complete stage-1 walk goes through the context descriptor table: Stream tables Ctx. Desc. tables Page tables +--------+ ,------->+-------+ ,------->+-------+ : : | : : | : : +--------+ | +-------+ | +-------+ SID->| STE |---' SSID->| CD |---' IOVA->| PTE |--> IPA +--------+ +-------+ +-------+ : : : : : : +--------+ +-------+ +-------+ Rewrite arm_smmu_write_ctx_desc() to modify context descriptor table entries. To keep things simple we only implement one level of context descriptor tables here, but as with stream and page tables, an SSID can be split to index multiple levels of tables.
