Subject: [PATCH 31/32] tracing: Make tracing_set_clock() non-static
Date: Mon, 26 Jun 2017 17:49:32 -0500 [thread overview]
Message-ID: <b135424dff05fbc8e4679b5b322f265a95f60193.1498510759.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1498510759.git.tom.zanussi@linux.intel.com>
In-Reply-To: <cover.1498510759.git.tom.zanussi@linux.intel.com>
Allow tracing code outside of trace.c to access tracing_set_clock().
Some applications may require a particular clock in order to function
properly, such as latency calculations.
Also, add an accessor returning the current clock string.
