2. AArch64 support. Linux driver uses VMSAv8-32 mode, while Xen driver enables Armv8 VMSAv8-64 mode to cover up to 40 bit input address. 3. Context bank (sets of page table) usage. In Xen, each context bank is mapped to one Xen domain. So, all devices being pass throughed to the same Xen domain share the same context bank. 4. IPMMU device tracking.

To do so, I made the following changes: - Configure SMMU to use 39 bit VA size and 40 bit PA size (4 KB page size) - Take the PGD pointer out of curr task_struct and pass it to the correct SMMU context bank PGD entry All other SMMU hardware configurations are the same as in arm-smmu.c. However, this leads to non-deterministic behavior. SMMU: System MMU . DVM support requires proper maintenace for system-wide page tables. ...

Aug 07, 2019 · ARM SMMU versions 1 and 2 The ARM SMMU specification outlines an IOMMU architecture for ARM processors, similar to Intel's VT-d. The SMMU mediates accesses to RAM by devices, and can translate addresses generated by DMA engines so as to correct them as the OS requires.

This series provides the support for turning on the arm-smmu's clocks/power domains using runtime pm. This is done using device links between smmu and client devices. The device link framework keeps the two devices in correct order for power-cycling across runtime PM or across system-wide PM. Dec 14, 2020 · Arm refers to a processor architecture, along with a large amount of intellectual property relating to microprocessor and microcontroller interfaces. Where consumer PCs tend to use x86-derived processors, or PowerPC, or MIPS, embedded electronics are most often implemented with Arm-core processors. The “core” of the processors are ....
