Subject: [PATCH v5 0/3] Cavium ARM64 uncore PMU support
Date: Wed, 17 May 2017 10:31:19 +0200 [thread overview]
Message-ID: <20170517083122.5050-1-jglauber@cavium.com> (raw)
Here is another attempt of adding support for some PMU counters on Cavium SOCs.
The major change is that I quit trying to merge the counters as it would
not fit with your requirements [1].
Another big change is that now the EDAC driver for the devices
carrying the PMU counters is upstream. I've added a simple callback
to the EDAC driver which owns the devices, so probing is much simpler now.
The driver still provides common "uncore" functions to avoid
code duplication and support adding more device PMUs (like L2 cache) in
the future.
