Subject: [PATCH 0/2] arm64 SMMUv3 PMU driver with IORT support
Date: Fri,  4 Aug 2017 15:59:12 -0400	[thread overview]
Message-ID: <1501876754-1064-1-git-send-email-nleeder@codeaurora.org> (raw)

This adds a driver for the SMMUv3 PMU into the perf framework.
It includes an IORT update to support PM Counter Groups.

IORT has no mechanism for determining device names so PMUs
are named based on their physical address. 

Tested on Qualcomm QDF2400. perf_fuzzer ran for 4+ hours
with no failures.
