Subject: [PATCH 3/3] arm64: Kconfig: Add support for the Perf NMI
Date: Sat, 16 May 2020 20:48:57 +0800	[thread overview]
Message-ID: <20200516124857.75004-4-lecopzer@gmail.com> (raw)
In-Reply-To: <20200516124857.75004-1-lecopzer@gmail.com>

This is an extending function for Pseudo NMI that registering
Perf events interrupts as NMI.

It's helpful for sampling irq-off context when using perf.
