[PATCH v1 0/4] x86,fs/resctrl: Pave the way for MPAM counter assignment

[Ben Horgan]

A little bit of preparatory work to get ready for MPAM counter
assignment. Resctrl gained support last year for counter assignment for AMD
machines supporting ABMC. Tighten a few things up, that weren't needed for
AMD, so that the MPAM driver can emulate ABMC and hence support counter
assignment.

Based on v7.0-rc1. The last patch [1] is only there to resolve the conflict
in the case that the mpam resctrl glue series [2] is merged first.

* arm_mpam: resctrl: Use new signature for resctrl_arch_is_evt_configurable()

Ben Horgan (4):
  x86,fs/resctrl: Make resctrl_arch_is_evt_configurable() aware of
    mbm_assign_mode
  fs/resctrl: Only show 'event_filter' files if events are configurable
  fs/resctrl: Disallow the software controller when mbm counters are
    assignable
  arm_mpam: resctrl: Use new signature for
    resctrl_arch_is_evt_configurable()
