About

This is a follow up of the RISC-V IOMMU work after the base support was accepted upstream in QEMU.

The following features will be implemented:

• HPM (Hardware Performance Monitor: this feature was split from the base support before merging it

• riscv-iommu-sys platform device

• MSI support for the riscv-iommu-sys platform device

• Integrate the riscv-iommu-sys platform device in the ‘virt’ machine

Project Scope and Timelines

The project will take place during 2025.

Components and Repos

Upstream Qemu.

Stakeholders and Partners

Other QEMU for RISC-V contributors, including:

• RISE

  • @Daniel Barboza

• External

  • Alistair Francis (QEMU for RISC-V maintainer)

Dependencies

No dependencies.

Measure of Success

An accepted and tested design and implementation in 2025.

RISE Requirements

None (not accounting any of existing engineering investment against RISE resources).
