Subject: [PATCH take2 2/3] unify PM-Timer messages
Date: Wed, 28 Jan 2009 12:52:24 +0900 [thread overview]
Message-ID: <497FD678.9000504@jp.fujitsu.com> (raw)
In-Reply-To: <497FD4F3.3080006@jp.fujitsu.com>
When LOCAL APIC was calibrated, the debug message is displayed as follows.
CPU0: Intel(R) Xeon(R) CPU 5110 @ 1.60GHz stepping 06
Using local APIC timer interrupts.
calibrating APIC timer ...
... lapic delta = 3773131
... PM timer delta = 812434
APIC calibration not consistent with PM Timer: 226ms instead of 100ms
APIC delta adjusted to PM-Timer: 1662420 (3773131)
TSC delta adjusted to PM-Timer: 159592409 (362220564)
..... delta 1662420
..... mult: 71411249
..... calibration result: 265987
..... CPU clock speed is 1595.0924 MHz.
..... host bus clock speed is 265.0987 MHz.
There are three type of PM-Timer (PM-Timer, PM Timer, and PM timer),
in this message. This patch unifies those messages to PM-Timer.
