From 80ec3552107ac16a836dbff4cf3c23fdd3256ee3 Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Mon, 28 Nov 2016 14:35:23 -0800 Subject: [PATCH] trace: Add an option for boot clock as trace clock Unlike monotonic clock, boot clock as a trace clock will account for time spent in suspend useful for tracing suspend/resume. This uses earlier introduced infrastructure for using the fast boot clock.
