Subject: [PATCH 33/33] perf tools: Allow TSC conversion on any arch
Date: Thu, 17 Jul 2014 13:12:35 -0300 [thread overview]
Message-ID: <1405613555-23380-34-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1405613555-23380-1-git-send-email-acme@kernel.org>
From: Adrian Hunter <adrian.hunter@intel.com>
It is possible to record a perf.data file on one architecture and
process it on another.
Consequently, TSC conversion functions need to be moved out of the arch
directory.
