RE: [Xen-users] ACPI HPET Timer - Works on standard Kernel - Broken onXen Kernel

["Robert Dunkley" <Robert@xxxxxxxxx>]

To answer my own question. Xen takes the hpet timer and hides it from Dom0 so this error is completely normal.

Subject: [Xen-users] ACPI HPET Timer - Works on standard Kernel - Broken onXen Kernel

 

I have an error in my dmesg system log about hpet not correctly enabling:

hpet_acpi_add: no address or irqs in _CRS

 

The same kernel without Xen enables it fine:

hpet0: at MMIO 0xfed00000 (virtual 0xffffffffff5fe000), IRQs 2, 8, 31

hpet0: 3 32-bit timers, 25000000 Hz

hpet_resources: 0xfed00000 is busy

 

Do I have to pass an additional boot option? (ACPI is already enabled) or is there something wrong with my Xen Kernel build? Anyone have any idea why the Xen kernel would break hpet support?

 

Thanks,

 

Rob
