Subject: [PATCHv2 0/3] [4.0] arm/arm64: Do not group hardware events from different PMUs
Date: Tue, 17 Mar 2015 18:14:57 +0000 [thread overview]
Message-ID: <1426616100-31628-1-git-send-email-suzuki.poulose@arm.com> (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.
This series hasn't changed since V1, except for better commit messages.
Similar fixes are required in ARM-CCN PMU driver and is not straight forward
as these changes.

arm/pmu: Reject groups spanning multiple hardware PMUs
arm64/pmu: Reject groups spanning multiple HW PMUs
arm-cci: Reject groups spanning multiple HW PMUs
