--Signature=_Fri__20_Apr_2007_19_54_44_+0800_z2EYpYx6uG5Mc7xD Content-Type: text/plain; charset=US-ASCII Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Will anybody object if I (or somebody else) commit this patch? http://people.freebsd.org/~ariff/test/k8_c1e.diff This should "fix" dead apic timer issues on latest AMD64 (Turion64 X2 mostly, or later revision) where C1 Enhanced (C1E) mode enabled. Without this, the only way to make the timer work is to disable APIC or even worst, to avoid executing HLT instruction (machdep.cpu_idle_hlt=3D0), smp or non-smp. It affect both i386 and amd64. See PR: i386/104678 for details. -- Ariff Abdullah FreeBSD ...
