Subject: [PATCH 0/2] arm64: perf: Add L2 cache events for ARMv8 PMuv3 and A53
Date: Thu, 20 Apr 2017 12:05:43 -0700	[thread overview]
Message-ID: <20170420190546.7453-1-f.fainelli@gmail.com> (raw)

Hi,

While investigating why there were no L2 cache events generated for a Cortex
A53-like PMU, it turned out that none of the L2 cache events were mapped.

This is also the case for ARMv8 PMUv3, which seems a little odd considering
they are defined.

Thanks!
