Subject: [PATCH V6 0/7] perf/amd/iommu: Enable multi-IOMMU support
Date: Fri, 23 Dec 2016 20:38:43 +0700 [thread overview]
Message-ID: <1482500330-5606-1-git-send-email-Suravee.Suthikulpanit@amd.com> (raw)
From: Suravee Suthikulpanit <ssuthiku-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
This patch series modifies the existing IOMMU and Perf drivers to support
systems with multiple IOMMUs by allocating an amd_iommu PMU per IOMMU instance.
This allows users to specify performance events and filters separately for each
IOMMU.
This has been tested on the new family17h-based server w/ multiple IOMMUs.
Git branch containing this patch series is available here:
https://github.com/ssuthiku/linux.git perf-iommu-v6
Changes from V5 (https://lkml.org/lkml/2016/2/23/370)
* Rebased onto v4.9.
* Remove the patch which consolidates function delclarations since
we have not yet agreed on the appropriate place for the new header file.
