Hi All,

I am looking into simulating a system with an IOMMU.
I could not find any details about IOMMU in the official documentation.
Is there support for IOMMU in full system simulation (for x86, Arm or RISC-V)?
If not, are there any known open-source projects that provide this
functionality to GEM5?

Thank you in advance.
Best regards,
Chathura

Hi Chathura,

I don’t know the other ISAs, but Arm supports an IOMMU (SMMU in Arm terminology):

Kind Regards

Giacomo

Hi Giacomo,

Thank you very much for pointing this out.
I missed the reply since it was in my spam folder.
