Hi all,

The rest of the driver can be found here: (no updated version - based on v3)

Does anyone know of a hosting platform that offers ARM machines that
have MPAM?

As far as I know there aren't any.

There is some MPAM support in the Orion Radxa board which is likely the
cheapest option. The MPAM acpi table isn't in the firmware though so
you'd need to load a custom table. James has this working.

I see there are Ampere systems on Oracle but I wasn't sure if those have
MPAM.

I'm getting a RISC-V QoS patch series ready (Ssqosid ext and CBQRI spec)
and I'd like to get a better understanding of how resctrl works on MPAM
in practice.

Thanks,
Drew

Thanks,
