vmx_add_host_load_msr() and vmx_add_guest_msr() share fair amount of code. Merge
them to simplify code maintenance.

There is a possibility that we set VPMU_CONTEXT_SAVE on VPMU context in
vpmu_load() and never clear it (because vpmu_save_force() will see

Add support for using NMIs as PMU interrupts to allow profiling hypervisor
when interrupts are disabled.
Most of processing is still performed by vpmu_do_interrupt(). However, since
certain operations are not NMI-safe we defer them to a softint that
vpmu_do_interrupt()
will schedule:
* For PV
Version 15 of PV(H) PMU patches.
Changes in v15:
* Rewrote vpmu_force_context_switch() to use continue_hypercall_on_cpu()
* Added vpmu_init initcall that will call vendor-specific init routines
* Added a lock to vpmu_struct to serialize pmu_init()/pmu_finish()
* Use SS instead of CS for DPL
Don't have the hypervisor update APIC_LVTPC when _it_ thinks the vector should
be updated. Instead, handle guest's APIC_LVTPC accesses and write what the guest
explicitly wanted.

Currently the quirk code for SandyBridge uses the VTd timeout value when
writing to an IGD register. This is the wrong timeout to use and, at
1000 msec, is much too large. Change this behavior by adding a new

Hi,
I am curious if Xen currently supports sharing hugepages between domains
(specifically ones originally allocated in Dom-0 and shared with a guest
r/w). I've seen some references to huge pages in the archives of this
list, but not in relation to the grant mechanism.
Also, can someone confirm

Originally the code allowed users to attach the same device more than
