X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2cb8eeaf00efc037988910de17ffe592b23941a6;p=thirdparty%2Fkernel%2Fstable.git

Merge tag 'x86_cache_for_v6.18_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 resource control updates from Borislav Petkov:
 "Add support on AMD for assigning QoS bandwidth counters to resources
  (RMIDs) with the ability for those resources to be tracked by the
  counters as long as they're assigned to them.

  Previously, due to hw limitations, bandwidth counts from untracked
  resources would get lost when those resources are not tracked.

  Refactor the code and user interfaces to be able to also support
  other, similar features on ARM, for example"
