Work in progress. The SMMU is what we use for device isolation, DMA
mapping. As for IRQ remapping, there isn't much to do there, as we only
inject virtual interrupts so far (GICv4 will change this, though A15
won't support it).
Thanks for the response.
Quick
question on SMMU for device isolation. Is this for isolation for
accesses from CPU cores to devices, or can SMMU also provide isolation
for DMA operations from the device to physical memory (like what IOMMU
provides) to safeguard against faulty writes ?_______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
