Initialize state_entry_time to zero for all idle vcpus NOW() is not usable since xen time sub-system hasn''t been initialized yet. On my box, it gives a initial stamp ~60s due to local tsc stamp as zero and TSC count is started from power on. Then a negative value is added to runstate of that idle vcpu at schedule p...

Hi all, this patch series introduces stolen ticks accounting for Xen on ARM. Stolen ticks are clocksource ticks that have been "stolen" from the cpu, typically because Linux is running in a virtual machine and the vcpu has been descheduled. To account for these ticks we introduce CONFIG_PARAVIRT and pv_time_ops so that we can make use of:

...e[RUNSTATE_running]; + totaltime = idletime + v->runstate.time[RUNSTATE_runnable] + + v->runstate.time[RUNSTATE_blocked] + + v->runstate.time[RUNSTATE_offline]; if ( v->is_running ) idletime += NOW() - v->runstate.state_entry_time; ret = -EFAULT; - if ( copy_to_guest_offset(idletimes, i, &idletime, 1) ) + if ( copy_to_guest_offset(idletimes, i, &idletime, 1) ) + goto out; + if ( copy_to_guest_offset(totaltimes, i, &totaltime, 1) ) go...

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen

This patchset is for more paravirtualization on ia64/pv_ops. - paravirtualize fsys call (fsys.S) by multi compile - paravirtualize gate page (gate.S) by multi compile - support save/restore For this purpose, the followings needs to be paravirtualized - ar.itc instruction - sched_clock() This is because timer may changed before/after saving/restoring. For convenience the working full

This is my current set of updates to Xen for 2.6.24. This is largely a bugfix set, and a couple of them are also relevent to 2.6.23. These are in the pre-x86 merge form; I'll update them once the merge goes into git. Quick overview: - remove some dead code in arch/i386/mm/init.c - clean up some duplicate includes - when sending an IPI, yield the vcpu if the destination doesn't have

This patch set is for the next merge window. They are just enhancements of the already merged patches or ia64 porting from x86 paravirt techniques and that their quality is enough for merge. This patch set is for more paravirtualization on ia64/xen domU. This patch set does - remove existing warnings - paravirtualize fsys call (fsys.S) by multi compile - paravirtualize gate page (gate.S) by multi

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-git13 + patches-2.6.21-git7-070507-1.tar.gz (I think "unwinder" is the only patch which doesn't apply to git13, and the sched-clock patches are the only ones which this series actually needs). Changes since the last posting: - More netfront review and cleanup - Added ability to

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-git3 + ff patches-2.6.21-git3-070501-1.tar.gz. Changes since the last posting: - reviews of xenbus (me), netfront (hch, rusty, herbert xu) and blockfront (hch), with most comments addressed. Netfront review revealed a couple of real bugs, and the code for all three is looking cleaner
