Subject: [PATCH v3 0/2] perf: measure page fault duration in perf trace
Date: Fri, 18 Nov 2016 01:21:36 +0100	[thread overview]
Message-ID: <20161118002138.29150-1-alexis.berlemont@gmail.com> (raw)

Hi,

Here is another attempt to make the perf-trace subcommand print the
page fault durations.

This solution is based on static tracepoints and it was necessary to
add 2 more tracepoints. I understood that adding tracepoints is a
questionable solution; I can try something else if someone has another
idea.

Alexis.
