Here is the download link for the latest release specification:
https://github.com/riscv-non-isa/riscv-iommu/releases/download/20260222/riscv-iommu.pdf
Alternatively, you can reference the GitHub repository:
https://github.com/riscv-non-isa/riscv-iommu
This specification includes both the IOMMU and HPM parts (sections 6.19 - 6.23).
