This series implements IOPMP specification v1.0.0-draft4 rapid-k model. 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
IOPMP takes a transaction which partially match an entry as a partially hit error. The transaction size is depending on source device, destination device and bus. Source device can send transaction information to IOPMP StreamSink. IOPMP will check partially hit with transaction information. If source device does not send transaction information, IOPMP will skip partially hit check. Changes for v3: - Remove iopmp_start_addr and iopmp_end_addr in MemTxAttrs - IOPMP: Get transaction_info from StreamSink instead of MemTxAttrs - ATCDMAC300: Convert ATCDMAC burst to AXI burst - ATCDMAC300: Send transaction_info to IOPMP StreamSink Ethan Chen (4): hw/core: Add config stream Add RISC-V IOPMP support hw/dma: Add Andes ATCDMAC300 support hw/riscv/virt: Add IOPMP support hw/core/Kconfig | 3 + hw/core/meson.build | 1 + hw/dma/Kconfig | 4 + hw/dma/atcdmac300.c | 566 ++++++++++ hw/dma/meson.build | 1 + hw/misc/Kconfig | 4 + hw/misc/meson.build | 1 + hw/misc/riscv_iopmp.c | 967 ++++++++++++++++++ hw/riscv/Kconfig | 2 + hw/riscv/virt.c | 72 +- include/hw/dma/atcdmac300.h | 180 ++++ include/hw/misc/riscv_iopmp.h | 342 +++++++ .../hw/misc/riscv_iopmp_transaction_info.h | 28 + include/hw/riscv/virt.h | 10 +- 14 files changed, 2178 insertions(+), 3 deletions(-) create mode 100644 hw/dma/atcdmac300.c create mode 100644 hw/misc/riscv_iopmp.c create mode 100644 include/hw/dma/atcdmac300.h create mode 100644 include/hw/misc/riscv_iopmp.h create mode 100644 include/hw/misc/riscv_iopmp_transaction_info.h -- 2.34.1
