RE: [Xen-devel] asterisk, ztdummy, and usb (and HZ = 100 under xen ???)

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

The x86 arch sets the kernel internal timer to 1000HZ by default, but
xen seems to set it to 100HZ (2.4 default).

The ztdummy driver makes the assumption that under 2.6, HZ = 1000, but
this isn't the case under xen which is probably the cause of all my
problems.

Is there a problem with me changing this, or is there a dynamic way to
change this???

Thanks

James
