This moves use_mm/unuse_mm from aio into mm, and optimizes atomic usage
there. Original patchset also exported use_mm/unuse_mm to modules, for
use by vhost, that bit will come in later when vhost is posted for
inclusion.
Michael S. Tsirkin (2):
mm: move use_mm/unuse_mm from aio.c to mm/
mm:
Anyone who wants to do copy to/from user from a kernel thread, needs
use_mm (like what fs/aio has). Move that into mm/, to make reusing and
exporting easier down the line, and make aio use it. Next intended
user, besides aio, will be vhost-net.

When mm switched to matches that of active mm, we don't need to
increment and then drop the mm count. In a simple benchmark this
happens in about 50% of time. Making that conditional reduces
contention on that cache line on SMP systems.

Hi all,
I have a strange problem with my bridges configuration. I have a
rhel5.4 host with kvm-83-105 package installed. This host has two
bridged interfaces defined to use with kvm guests:

ONBOOT=yes
TYPE=Bridge
IPADDR=172.26.50.14
NETMASK=255.255.255.240

irqfd/eventfd is the abstraction layer, it doesn't need to be reabstracted.
Not per se, but it needs to be interfaced. How do I register that
eventfd with the fastpath in Ira's rig? How do I signal the eventfd
(x86-ppc, and ppc-x86)?
The solution is, to delete
/etc/udev/rules.d/70-persistent-net.rules
in the guest and reboot. This is an autogenerated file, which stores the
mapping of MAC adresses to interface names. Since my MAC address changed, the
interface wasn't automatically added anymore.

Hi,

Hi,
I have question on i82557b emulation in kvm.
I have run a proprietary operating system (Pharlap OS) in kvm. Part of the job
has been porting driver for i8255x. During the job I discovered that kvm's
emulation doesn't support a RNR interrupt (it is disabled in the code).
Why is it

Commit 56aebc891674cd2d07b3f64183415697be200084 changed gdbstub in way
that debugging 32 or 16-bit guest code is no longer possible with qemu
for x86_64 guest CPUs. Since that commit, qemu only provides registers
sets for 64-bit, forcing current and foreseeable gdb to also switch its
architecture
Err, I'll take this one back for now pending some more discussion.
What we need more urgently is the writeback cache flag, which is now
implemented in qemu, patch following ASAP.

Hi!
Thank you for explaining.
Measurements of older versions of virtio proved that we can cancel this
timer and achieve better latency while not hurting throughput.
Well, I did try the patch Michael is suggesting here:
Hopefully the last regression of 4c0960c0: KVM_SET_GUEST_DEBUG requires
properly synchronized guest registers (on x86: eflags) on entry.

The output from the /sbin/ip utility has changed, adding two

depending on the last column being the interface name.
Change this from $NF to $5.
