Reinette,

It seems unlikley that I'll be able to close every open. But I'll
keep trying as you point them out.

I've just pushed an updated set of patches to:

  git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux.git resctrl_v65

Rebased to v6.5. Includes the module auto-load code discussed in
previous e-mail.

James: 

I'm now hoping for some feedback from ARM folks on whether this is a
useful direction. Is it possible to implement MPAM features on top of
this base architecture independent layer. If not, am I just missing
some simple extensions that you will need. Or is there some fundamental
problem that looks hard/impossible to resolve?

Babu:

Can you try this out on an AMD system. I think I covered most of the
existing AMD resctrl features, but I have no machine to test the code
on, so very likely there are bugs in these code paths.

I'd like to make any needed changes now, before I start breaking this
into reviewable bite-sized patches to avoid too much churn.
