2023-05-30hw/arm/smmuv3: Add knob to choose translation stage and enable stage-2Mostafa Saleh
As everything is in place, we can use a new system property to advertise which stage is supported and remove bad_ste from STE stage2 config. The property added arm-smmuv3.stage can have 3 values: - "1": Stage-1 only is advertised. - "2": Stage-2 only is advertised. If not passed or an unsupported value is passed, it will default to stage-1. Advertise VMID16. Don't try to decode CD, if stage-2 is configured.

2023-05-30hw/arm/smmuv3: Parse STE config for stage-2Mostafa Saleh
Parse stage-2 configuration from STE and populate it in SMMUS2Cfg. Validity of field values are checked when possible. Only AA64 tables are supported and Small Translation Tables (STT) are not supported. According to SMMUv3 UM(IHI0070E) "5.2 Stream Table Entry": All fields with an S2 prefix (with the exception of S2VMID) are IGNORED when stage-2 bypasses translation (Config[1] == 0). Which means that VMID can be used(for TLB tagging) even if stage-2 is bypassed, so we parse it unconditionally when S2P exists. Otherwise it is set to -1.(only S1P) As stall is not supported, if S2S is set the translation would abort. For S2R, we reuse the same code used for stage-1 with flag record_faults. However when nested translation is supported we would need to separate stage-1 and stage-2 faults. Fix wrong shift in STE_S2HD, STE_S2HA, STE_S2S.

2023-02-16hw/arm/smmuv3: Add GBPA registerMostafa Saleh
GBPA register can be used to globally abort all transactions. It is described in the SMMU manual in "6.3.14 SMMU_GBPA". ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to be zero(Do not abort incoming transactions). Other fields have default values of Use Incoming. If UPDATE is not set, the write is ignored. This is the only permitted behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure) As this patch adds a new state to the SMMU (GBPA), it is added in a new subsection for forward migration compatibility. GBPA is only migrated if its value is different from the reset value. It does this to be backward migration compatible if SW didn't write the register.

2022-12-15hw/arm: Convert TYPE_ARM_SMMUV3 to 3-phase resetPeter Maydell
Convert the TYPE_ARM_SMMUV3 device to 3-phase reset. The legacy reset method doesn't do anything that's invalid in the hold phase, so the conversion only requires changing it to a hold phase method, and using the 3-phase versions of the "save the parent reset method and chain to it" code.

2018-06-26hw/arm/smmuv3: Cache/invalidate config dataEric Auger
Let's cache config data to avoid fetching and parsing STE/CD structures on each translation. We invalidate them on data structure invalidation commands. We put in place a per-smmu mutex to protect the config cache. This will be useful too to protect the IOTLB cache. The caches can be accessed without BQL, ie. in IO dataplane. The same kind of mutex was put in place in the intel viommu.
