Subject: [PATCH v2 07/37] tracing: hrtimer: Take all clock bases and modes into account
Date: Sun, 22 Oct 2017 23:39:45 +0200 [thread overview]
Message-ID: <20171022214051.980036959@linutronix.de> (raw)
In-Reply-To: 20171022213938.940451689@linutronix.de
[-- Attachment #1: tracing--hrtimer--Take-all-bases-and-modes-into-account.patch --]
[-- Type: text/plain, Size: 1643 bytes --]
So far only CLOCK_MONOTONIC and CLOCK_REALTIME were taken into account as
well as HRTIMER_MODE_ABS/REL in hrtimer_init tracepoint. The query for
detecting timer mode ABS or REL is not valid, since the introduction of
HRTIMER_MODE_PINNED.
HRTIMER_MODE_PINNED is not evaluated in hrtimer_init() call. But for the
sake of completeness print all given modes.
