For ARM linux-user mode signal handlers, fill in the ucontext with
VFP register contents in the same way that the kernel does. We only
do this for v2 format sigframe (2.6.12 and above); this is actually
bug-for-bug compatible with the older kernels, which don't save and
restore VFP registers
The padding in the target_ucontext_v2 is defined by the size of
the target's sigset_t type, not the host's. (This bug only causes
problems when we start using the uc_regspace[] array to expose
VFP registers to userspace signal handlers.)

I'd like to disable bandwidth limit or make it very high,
Use int64_t all over to make values = 4g work.

There's no need to flush requests after vmstop
as vmstop does it for us automatically now.

Avoid sending out packets, and modifying
device state, when VM is stopped.
Add a bunch or assert statements to verify this does not happen.

I sent the exact same patches offline to some of the Cc'd,
there's been no change but they have been tested by Jason now.
I'll queue them up unless there are some comments.
What these patches do is arrive at a state where migrate to exec with vm
stopped produces a stable result.
With these
This makes ram block ordering under migration stable, ordered by offset.
This is especially useful for migration to exec, for debugging.

DMA into memory while VM is stopped makes it
hard to debug migration (consequitive saves
result in different files).
Fixing this completely is a large effort,
this patch does this for virtio-net.

Test 019 can be run with qcow2 and qed image formats. Replace the

I don't know the Linux SCSI stack, so some basic questions for you :).
With scsi-generic I can send SCSI commands to a device. How is bsg
different? The bsg code looks cleaner than sg but they both boil down
to issuing SCSI
Nick,
can we wait a bit with this series? With the threadlets currently
pending for inclusion I can get my rewrite of the generic-generic
to not abuse the qemu block layer out of the closet again, which
should simplify a lot of the things you're touching here.
This patch adds support for expiring passwords to vnc. It adds a new
vnc_display_pw_expire() function which specifies the time when the
password will expire.

protocol_client_auth_vnc() has two places where the auth can fail,
with identical code sending the reject message to the client.
Move the common code to the end of the function and make both
error paths jump there. No functional change.

This patch series adds new monitor commands to set and expire
the password:
set-password $protocol $secret
expire-password $protocol [ now | never | +secs | secs ]
The time when the password expires can be specified either relative
(+60 == password expires in 60 seconds from now) or absolute
I don't really see the point of this. It's implemented as a protocol,
and thus the bottom of the qemu protocol stack. So we might get SCSI
commands in from the guest, decode them, just to re-encode them again
and send them off to the network all inside qemu.
Do you have any performance numbers
This patch adds new set_password and expire_password monitor commands
which allows to change and expire the password for spice and vnc
connections. See the doc update patch chunk for details.

Traditionally, the linux stack is using SCSI status codes

A SCSI emulation should naturally return the SAM defined codes,
not the linux ones.

What happend to my comment that the iov and non-iov case should share
