Subject: [PATCH v2 2/5] arm64: dts: ls1088a: add missing PMU node
Date: Mon, 26 Jul 2021 07:12:13 +0000 [thread overview]
Message-ID: <20210726071216.22711-3-matt@traverse.com.au> (raw)
In-Reply-To: <20210726071216.22711-1-matt@traverse.com.au>
The Performance Manager Unit was not described in the DTS
which meant performance event monitoring was not possible.
This was exposed by a change to the PMU handling in KVM
in 5.11-rc3 which now prevents a PMU being exposed to a
guest when the host does not provide one:
"KVM: arm64: Don't access PMCR_EL0 when no PMU is available"
Signed-off-by: Mathew McBride <matt@traverse.com.au>
