"WebWhen the value of the ENABLE bit is 1, ISTATUS indicates whether the timer condition is met. ISTATUS takes no account of the value of the IMASK bit. If the value of ISTATUS is 1 and the value of IMASK is 0 then the timer interrupt is asserted. When the value of the ENABLE bit is 0, the ISTATUS field is UNKNOWN. Access to this field is RO.

WebThe original timer slop value has not changed since the introduction of the Xen-aware Linux kernel code. This commit provides users an opportunity to tune timer performance given the refinements to hardware and the Xen event channel processing. It also mirrors a feature in the Xen hypervisor - the "timer_slop" Xen command line option.
