This file holds the UEFI build and evaluate instructions for RiscV Virt machine including a S-Mode EDK2 firmware and a StandaloneMm firmware which can be taken as a payload of the OpenSBI and run in a domain isolated by using the PMP/sPMP (re-used some Penglai code and put to OpenSBI).
We added MM service group in the RPMI spec https://docsgithub.google.com/document/d/18lupciraX5_EVtNS984apTTO3Sti6ln3BqMzgTSfYHEriscv-non-isa/riscv-rpmi, and evaluted the StandaloneMmPkg proejct based on the RPMI PoC mentioned here https://lists.riscv.org/g/tech-prsrpmi/message/59390.
How to build (Linux Environment)
...
Create a directory that would hold source code of the components.
- EDK2: https://github.com/yli147/edk2/tree/dev-standalonemm-mpxy-rpmiv3
- OpenSBI: https://github.com/Penglai-Enclaveyli147/opensbi/tree/dev-standalonemm-rpmimpxy-v3
- QMEU: https://github.com/yli147/qemu/commitstree/dev-standalonemm-rpmimpxy
Manually build
Compile QEMU
```
git clone https://github.com/yli147/qemu.git -b dev-standalonemm-rmpirpmi
export WORKDIR=`pwd`
cd qemu
./configure --target-list=riscv64-softmmu
make -j $(nproc)
```
...
```
cd $WORKDIR
