Subject: [PATCH 36/36] x86: KVM guest: kvm_get_tsc_khz: return khz, not lpj
Date: Sun, 14 Dec 2008 10:07:09 +0200 [thread overview]
Message-ID: <1229242029-13410-37-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1229242029-13410-1-git-send-email-avi@redhat.com>
From: Eduardo Habkost <ehabkost@redhat.com>
kvm_get_tsc_khz() currently returns the previously-calculated preset_lpj
value, but it is in loops-per-jiffy, not kHz. The current code works
correctly only when HZ=1000.
