[Xen-devel] [PATCH v2 00/13] x86/PMU: Xen PMU PV support

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

Changes in v2:

* Xen symbols are exported as data structure (as opoosed to a set of formatted
strings in v1). Even though one symbol per hypercall is returned performance 
appears
to be acceptable: reading whole file from dom0 userland takes on average about
twice as long as reading /proc/kallsyms

* More cleanup of Intel VPMU code to simplify publicly exported structures

* There is an architecture-independent and x86-specific public include files 
(ARM
has a stub)

* General cleanup of public include files to make them more presentable (and
to make auto doc generation better)

* Setting of vcpu->is_running is now done on ARM in schedule_tail as well 
(making
changes to common/schedule.c architecture-independent). Note that this is not
tested since I don't have access to ARM hardware.

* PCPU ID of interrupted processor is now passed to PV guest


Linux patches will be updated later.

===================================================================
