Subject: [PATCH v2 00/12] arm_mpam: minor fixes at v7.2
Date: Thu, 17 Sep 2026 15:56:05 +0100	[thread overview]
Message-ID: <20260917145617.2202986-1-ben.horgan@arm.com> (raw)

Despite the subject this is still relevant at v7.3.  This series
addresses a few minor issues in the driver.  Since v1 I've added an
extra patch at the end to fix a leak and reworked the mbwu save/restore
fixes to avoid races by dropping the mon_sel lock in the middle.

Changelogs in patches

Based on v7.3-rc2

Ben Horgan (12):
  arm_mpam: Move MPAMF_ECR write helpers to allow reuse
  arm_mpam: Restore the error interrupt enable from mpam_cpu_online()
  arm_mpam: Set mpam_feat_msmon_mbwu_31counter when there are bandwidth
    counters
  arm_mpam: Add missing mon_sel locking in MBWU save and restore
  arm_mpam: Ensure MBWU counters are reset on restore
  arm_mpam: Use __ris_msmon_read() for saving MBWU state
  arm_mpam: Initialize all of struct mon_read in
    mpam_restore_mbwu_state()
  arm_mpam: resctrl: Correct check that existing class is L3
  arm_mpam: resctrl: Make read_mon_cdp_safe() self consistent
  arm_mpam: Don't loop forever if there is the maximum possible amount
    of PARTIDs
  arm_mpam: Switch to kvzmalloc_objs() for allocation of component cfg
  arm_mpam: resctrl: Don't stop early when tearing down a class
