Enhance the KVM ONE_REG capability within S390 to allow
getting/setting the following special cpu registers: clock comparator

Folks,
today we discussed the situation of a qemu crash (with coredump) and big guests.
Quite often the guest pages are not needed but make the core file pretty big.
The most appealing proposal that we had was to adopt the core file code in the

Marcelo, Gleb, Frederic,
sorry for spotting this so late. Here is a fix for a bug in kvm on s390

Gleb, Paolo,
here is a set of patches containing the floating interrupt controller
and the async page fault patches on top of them. (It took a bit
longer than expected)
Several changes since v4 of the async patches mostly to make life
migration possible:
- Please have a look at patch 5. This

This patch adds a floating irq controller as a kvm_device.
It will be necessary for migration of floating interrupts as well
Folks,
from time to time I update valgrind or qemu to work reasonably well
with KVM.
Now, newer KVMs have the ability to create subdevices of a KVM guest (e.g. an
in kernel
kvm interrupt controller) with the following ioctl:
#define KVM_CREATE_DEVICE _IOWR(KVMIO, 0xe0, struct

for the unconverted
use of hlist_for_each_entry_rcu, hlist_add_head_rcu, hlist_del_init_rcu
is necessary, though. They look fine to me since they are protected by
outer functions.
In addition, we should also discuss if a global srcu (for all guests) is
fine.

That's nice but did you try to measure the overhead
on some interrupt-intensive workloads
