Description:
Deploy EDK2 to run on 64-core CPU under RISC-V architecture, and successfully
boot to OS.
Implementation can be found on
https://github.com/AII-SDU/edk2-platforms/tree/devel-Sophgo/SG2042Pkg/Platform/Sophgo.
Current progress and status:
1.Adopted the scheme of separating OpenSBI and EDK2. It follows PEI less
design.
2.The startup process is roughly: ZSBL + FSBL + OpenSBI + EDK2 + GRUB + Linux
OS.
The boot medium is SD card, where ZSBL is loaded and executed by an
auxiliary MCU, performing initial initialization
operations such as DIMM initialization. FSBL then continues with further
initialization tasks. OpenSBI is used to
initialize the hardware platform and kernel. Additionally, we have upgraded
the OpenSBI from version V0.9 to V1.2 to
align with community progress. EDK2, running in S-mode, handles
configuration operations, primarily completing the
SD card driver in the DXE stage, while PCIe driver testing and follow-up
work are planned. GRUB2 is used to load the
operating system, facilitating subsequent operations.
Testing:
1.Test the project on Sophgo SG2042 EVB and be able to launch Linux OS
2.Test the project on Milk V Pioneer board and is able to boot into the UEFI
shell.
However, the SD card driver could not correctly recognize all partitions
and start Linux OS.
Current limitation:
1.PCIE driver is not currently supported.
2.MMU support
SG2042 (Xuantie C920) MMU can be enabled in SV39 mode. Introduce the PCD
variable
PcdForceNoMMU to disable MMU configuration. Currently, enabling MMU results
in a
timeout for reading data blocks from the SD card, So MMU is disabled by
default.
3.Clang toolchain support
Build the port using the CLANGDWARF toolchain (clang version 18.0.0). It is
able
to build successfully but the compiled binary was not fully work.
