Subject: [PATCH 7/7] HPET: simplify initialization message
Date: Tue, 04 Oct 2005 14:42:04 +0200 (MEST) [thread overview]
Message-ID: <20051004124204.23057.29610.schnuffi@turing> (raw)
In-Reply-To: <20051004124126.23057.75614.schnuffi@turing>
From: Clemens Ladisch <clemens@ladisch.de>
When booting, display the timer frequency in Hertz instead of as tick
length in nanoseconds. Apart from saving a local variable, this makes
the message more easily comprehensible.
