Subject: [PATCH v6 0/7] x86,fs/resctrl: Pave the way for MPAM counter assignment
Date: Tue, 5 May 2026 16:57:34 +0100 [thread overview]
Message-ID: <20260505155741.3591201-1-ben.horgan@arm.com> (raw)
No functional changes from v5. Just comment and commit message changes based on
review comments. Changelogs in patches.
Description from a previous version's cover letter:
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 v7.1-rc2
