Subject: [patch 14/17] MIPS : export hpt frequency for trace_clock.
Date: Wed, 12 Nov 2008 18:16:05 -0500 [thread overview]
Message-ID: <20081112232300.510951002@polymtl.ca> (raw)
In-Reply-To: 20081112231551.473569400@polymtl.ca
[-- Attachment #1: mips-export-hpt-frequency-for-trace-clock.patch --]
[-- Type: text/plain, Size: 1393 bytes --]
Trace_clock needs to export the hpt frequency to modules (e.g. LTTng).
