Re: [Xen-ia64-devel] SEDF scheduler

Hi Trisran,

The SEDF scheduler bugs are only xen/ia64.
To be precise, the SEDF scheduler source codes does not include bugs.
Because there are not the following functions, action of the SEDF 
scheduler becomes inaccuracy.

 - xen/ia64
  -- __HYPERVISOR_sched_op / do_sched_op()
  -- __HYPERVISOR_set_timer_op / do_set_timer_op()
 - kernel/dom0 & domU
  -- xen_idle() / EXPORT_SYMBOL(default_idle)
  -- stop_hz_timer()
  -- start_hz_timer()

Best regards,
 Kan
