It is not > obvious to me how this also closes the other opens. 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. -Tony
