Subject: Re: [PATCH v5 00/40] x86/resctrl: Move the resctrl filesystem code to
 /fs/resctrl

Hi James,

While you wait for folks to consider these changes, could you please take a look
at [1] from an Arm/MPAM perspective? My understanding is that Arm/MPAM also
requires assigning counters to do monitoring and [1] aims to create
a generic interface to do so. Is [1] something that Arm/MPAM can build on
or are there some changes that can be made before its inclusion to help 
with future MPAM support?

Thank you

Reinette
