Applied, after a lot of restructuring. Also, would it be cleaner to set up the HPET to do direct FSB writes to a local APIC, rather than hijacking PIT ch0? There are some corner cases where we leave PIT ch0 enabled after boot. Do most HPET implementations support direct FSB interrupt delivery? -- Keir On 20/5/08 16:22, "Wei, Gang" <gang.wei@xxxxxxxxx> wrote: > Local APIC timer may stop at deep C state (C3/C4...) entry/exit. this > patch add the logic that use platform timer (HPET) to reenable local > APIC timer at C state entry/exit. > > Signed-off-by: Wei Gang <gang.wei@xxxxxxxxx> > Signed-off-by: Yu Ke <ke.yu@xxxxxxxxx> _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
