Hi,
This is version 4 of a series of patches that I originally posted in:

Changes since version 3:
in patch part 1/5 and part 4/5
- Added stub functions for 'target_reset_irq_delivered' and
'target_get_irq_delivered'. Added registration functions
that are used by apic code to replace the stubs.
- Removed NULL pointer checks from update_irq().
in patch part 5/5
- A minor modification in hpet_timer_has_tick_backlog().
- Renamed the local variable 'irq_count' in hpet_timer() to
'period_count'.
- Driftfix-related fields in struct 'HPETTimer' are no longer
being initialized/reset in hpet_reset(). Added the function
hpet_timer_driftfix_reset() which is called when the guest
. sets the 'CFG_ENABLE' bit (overall enable)
in the General Configuration Register.
. sets the 'TN_ENABLE' bit (timer N interrupt enable)
in the Timer N Configuration and Capabilities Register.
Please review and please comment.
Regards,
Uli
