Jan,
While the patch itself looks fine, IMO it would be better to move all of
the timer handling to userspace, except the performance critical parts,
since most of it is generic. Either periodic or one-shot timer, with:
- PIO or MMIO region returns remaining time for expiration.
- PIO or MMIO region programs the next event and timer mode.
Oversimplified of course (kvm_timer_ops was the first step in that
direction). I believe there will be a proposed HPET in-kernel driver.
I don't see what is the problem with partial components that Avi talks
about.
