Subject: [PATCH 0/5] Fix Arm system PMU hotplug issues
Date: Mon, 4 Feb 2019 17:09:03 +0000 [thread overview]
Message-ID: <cover.1549299188.git.robin.murphy@arm.com> (raw)
Hi all,
Following the report of a preemption-related bug in arm-cci, it turns
out there's a fair bit of cleaning up to do in this area. I've started
here with the Arm drivers that I'm fairly familiar with - I suspect the
hisi/qcom/xgene ones suffer from similar issues, but it's going to take
me a while longer to figure them out in detail.
Robin.
