Each of these IO virtualization blocks consists of an Arm SMMUv3, a GIC-ITS and a NCI (network chip interconnect). SoC expansion blocks connect to the IO virtualization blocks via x4, x8 or x16 ports exposed by the system. A SoC expansion block implementation includes 2 UARTs, 2 DMA devices and 2 Memory nodes. In addition, Arm reference design platforms support Virtio-P9 device as part of the Rest of System (RoS). The Virtio-P9 device implements a subset of the Plan 9 file protocol over a virtio transport that enables accessing a shared directory on the host's filesystem from a running FVP platform. This patch series adds SSDT tables for various RD-N2 platforms such as RD-N2, RD-N2-Cfg1, and RD-N2-Cfg2 to describe the SoC expansion block devices - UARTs, and DMAs and the Virtio-P9 devices present on the platforms. The patches also add support for platform DXE driver to initialize the UARTs that are present in SoC expansion blocks. By default these UARTs are kept disabled and can be enabled with a Pcd - PcdIoVirtSocExpBlkUartEnable. This patch series is now a combination of two patch series [1] and [2] that added Virtio-P9 support and SoC expansion block (non-discoverable) IO block for RD-N2: [edk2-platforms][PATCH V1 0/2] Enable Virtio-P9 on RD-N2 platforms [edk2-platforms][PATCH V1 0/6] Add non-discoverable IO block for Rd-N2 [1] https://edk2.groups.io/g/devel/message/94936 [2] https://edk2.groups.io/g/devel/message/86646 Changes since v1: - Minor update to Virtio-P9 SSDT table: - Name of the DefinitionBlock() is set to SsdtRosVirtioP9.aml rather than SsdtRosVirtioP9Table.aml - Updates to SoC expansion block: - Removed IORT table for SoC expansion block and kept only the SSDT table for devices. - SSDT table now uses arithmetic operations to calculate the start and end addresses of the devices in QWordMemory() blocks. - The number of PCDs for UARTs and DMAs are now reduced as the addresses are now calculated within the SSDT table based on the SoC expansion block base address and device offsets. - Defined macros for Interrupt() block for various DMA nodes. - Removed the first patch of the series that added PCDs for SMMU: [PATCH V1 1/6] Platform/Sgi: add PCDs for SMMUv3 base address and in= terrupts - Added support for SoC expansion block on RD-N2-Cfg2 platform as well.
