Subject: [PATCH v2 00/13] x86/PMU: Xen PMU PV support
Date: Fri, 20 Sep 2013 05:41:59 -0400 [thread overview]
Message-ID: <1379670132-1748-1-git-send-email-boris.ostrovsky@oracle.com> (raw)
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.
