This series implements IOPMP specification v1.0.0-draft4 rapid-k model:
https://github.com/riscv-non-isa/iopmp-spec/blob/main/riscv_iopmp_specification.pdf
When IOPMP is enabled, a DMA device ATCDMAC300 is added to RISC-V virt platform.
This DMA devce is connected to the IOPMP and has the functionalities required
by IOPMP, including:
- Support specify source-id (SID)
- Support asynchronous I/O to handle stall transcations
Ethan Chen (6):
exec/memory: Introduce the translate_size function within the IOMMU
class
system/physmem: IOMMU: Invoke the translate_size function if it is
implemented
exec/memattrs: Add iopmp source id to MemTxAttrs
Add RISC-V IOPMP support
hw/dma: Add Andes ATCDMAC300 support
hw/riscv/virt: Add IOPMP support
