Subject: [PATCH 0/3] [4.0] arm/arm64: Do not group hardware events from different PMUs
Date: Mon, 9 Mar 2015 12:43:05 +0000 [thread overview]
Message-ID: <1425904988-10452-1-git-send-email-a> (raw)
From: "Suzuki K. Poulose" <suzuki.poulose@arm.com>
This is a collection of fixes which denies grouping hardware events
from different PMUs. They also fix crashes triggered by perf_fuzzer
on Linux-4.0-rc2.
Pawel,
Similar fix is required in ARM CCN PMU driver. I didn't find it
straight forward to fix it there. Could you please take a look
into it ?
