492c30af25 Make DMA bottom-half driven (v2)
The current DMA routines are driven by a call in main_loop_wait() after every
select.

This patch converts the DMA code to be driven by a constantly rescheduled
bottom half.  The advantage of using a scheduled bottom half is that we can
stop scheduling the bottom half when there no DMA channels are runnable.  This
means we can potentially detect this case and sleep longer in the main loop.

The only two architectures implementing DMA_run() are cris and i386.  For cris,
I converted it to a simple repeating bottom half.  I've only compile tested
this as cris does not seem to work on a 64-bit host.  It should be functionally
identical to the previous implementation so I expect it to work.

For x86, I've made sure to only fire the DMA bottom half if there is a DMA
channel that is runnable.  The effect of this is that unless you're using sb16
or a floppy disk, the DMA bottom half never fires.

You probably should test this malc.  My own benchmarks actually show slight
improvement by it's possible the change in timing could affect your demos.

Since v1, I've changed the code to use a BH instead of a timer.  cris at least
seems to depend on faster than 10ms polling.

1b435b1032 Make bottom halves more robust
Bottom halves are supposed to not complete until the next iteration of the main
loop.  This is very important to ensure that guests can not cause stack
overflows in the block driver code.  Right now, if you attempt to schedule a
bottom half within a bottom half callback, you will enter an infinite loop.

This patch uses the same logic that we use for the IOHandler loop to make the
bottom half processing robust in list manipulation while in a callback.

This patch also introduces idle scheduling for bottom halves.  qemu_bh_poll()
returns an indication of whether any bottom halves were successfully executed.
qemu_aio_wait() uses this to immediately return if a bottom half was executed
instead of waiting for a completion notification.

qemu_bh_schedule_idle() works around this by not reporting the callback has
run in the qemu_bh_poll loop.  qemu_aio_wait() probably needs some refactoring
but that would require a larger code audit.  idle scheduling seems like a good
compromise.

9f7965c7e9 Expand cache= option and use write-through caching by default
This patch changes the cache= option to accept none, writeback, or writethough
to control the host page cache behavior.  By default, writethrough caching is
now used which internally is implemented by using O_DSYNC to open the disk
images.  When using -snapshot, writeback is used by default since data integrity
it not at all an issue.

cache=none has the same behavior as cache=off previously.  The later syntax is
still supported by now deprecated.  I also cleaned up the O_DIRECT
implementation to avoid many of the #ifdefs.

negative error codes.  This is necessary to detect things like closed

It also removes unused code for QEMUFileFD write path.  Finally, it

475e427772 Switch the memory savevm handler to be "live"
This patch replaces the static memory savevm/loadvm handler with a "live" one.
This handler is used even if performing a non-live migration.

The key difference between this handler and the previous is that each page is
prefixed with the address of the page.  The QEMUFile rate limiting code, in
combination with the live migration dirty tracking bits, is used to determine
which pages should be sent and how many should be sent.

The live save code "converges" when the number of dirty pages reaches a fixed
amount.  Currently, this is 10 pages.  This is something that should eventually
be derived from whatever the bandwidth limitation is.

9366f41860 Introduce v3 of savevm protocol
The current savevm/loadvm protocol has some draw backs.  It does not support
the ability to do progressive saving which means it cannot be used for live
checkpointing or migration.  The sections sizes are 32-bit integers which
means that it will not function when using more than 4GB of memory for a guest.
It attempts to seek within the output file which means it cannot be streamed.
The current protocol also is pretty lax about how it supports forward
compatibility.  If a saved section version is greater than what the restore
code support, the restore code generally treats the saved data as being in
whatever version it supports.  This means that restoring a saved VM on an older
version of QEMU will likely result in silent guest failure.

This patch introduces a new version of the savevm protocol.  It has the
following features:

 * Support for progressive save of sections (for live checkpoint/migration)
 * An asynchronous API for doing save
 * Support for interleaving multiple progressive save sections
   (for future support of memory hot-add/storage migration)
 * Fully streaming format
 * Strong section version checking

03ff3ca30f Use common objects for qemu-img and qemu-nbd
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the
code.  It's ugly and causes us to have to build multiple object files for
linking against qemu and the tools.

This patch introduces a new file, qemu-tool.c which contains enough for
qemu-img, qemu-nbd, and QEMU to all share the same objects.

This also required getting qemu-nbd to be a bit more Windows friendly.  I also
changed the Windows block-raw to use normal IO instead of overlapping IO since
we don't actually do AIO yet on Windows.  I changed the various #if 0's to
 #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows.

After this patch, there are no longer any #ifdef's related to qemu-img and
qemu-nbd.

5d0c5750bb usb: Support for removing device by host addr, improved auto filter syntax (Max Krasnyansky)
This patch adds support for removing USB devices by host address.
Which is usefull for things like libvirtd because there is no easy way to
find guest USB address of the host device.
In other words you can now do:
   usb_add host:3.5
   ...
   usb_del host:3.5
Before the patch 'usb_del' did not support 'host:' notation.

----
Syntax for specifying auto connect filters has been improved.
Old syntax was
    host:bus.dev
    host:pid:vid
New syntax is
    host:auto:bus.dev[:pid:vid]
In both the cases any attribute can be set to "*".

New syntax is more flexible and lets you do things like
    host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */

It's now possible to remove auto filters. For example:
    usb_del host:auto:3.*:5533:*

Active filters are printed after all host devices in 'info usb' output.
Which now looks like this:

  Device 1.1, speed 480 Mb/s
    Hub: USB device 1d6b:0002, EHCI Host Controller
  Device 1.4, speed 480 Mb/s
    Class 00: USB device 1058:0704, External HDD
  Auto filters:
    Device 3.* ID *:*

baf35cb902 Use signalfd() to work around signal/select race
This patch introduces signalfd() to work around the signal/select race in
checking for AIO completions.  For platforms that don't support signalfd(), we
emulate it with threads.

There was a long discussion about this approach.  I don't believe there are any
fundamental problems with this approach and I believe eliminating the use of
signals is a good thing.

I've tested Windows and Linux using Windows and Linux guests.  I've also checked
for disk IO performance regressions.

563e3c6e6e Parallel Port Direction Fix
The direction bit in the control register should not be directly

set using PPWCONTROL. The kernel gives the following debug message.

    parport0 (ppdev0): use data_reverse for this!

More over setting the data pins to forward mode does not work,
perhaps a bug in the Linux PP driver. The right way to do this is
to use PPDATADIR to set the direction. The patch checks if the
user is toggling the direction bit, and invokes PPDATADIR to
do the job.

bcfad70fb0 add DisplayState->idle (Samuel Thibault)
Add idle field to DisplayState struct, so drivers can figure
the display is idle and take advantage of that.

The xen framebuffer driver will use this to communicate the
idle state to the guest, so it knows it can stop doing updates

5b08fc106d Handle terminating signals (Gerd Hoffmann)
This patch makes qemu handle signals better.  It sets the request_shutdown
flag, making the main_loop exit and qemu taking the usual exit route, with
atexit handlers being called and so on, instead of qemu just being killed
by the signal.

To avoid calling vm_start() from the signal handler main_loop() got an
additional check so qemu_system_shutdown_request() works even when the
vm is in stopped state.

4b096fc9ec husb: support for USB host device auto connect (Max Krasnyansky)
QEMU can now automatically grab host USB devices that match the filter.
For now I just extended 'host:X.Y' and 'host:VID:PID' syntax to handle
wildcards. So for example if you do something like
   usb_add host:5.*
QEMU will automatically grab any non-hub device with host address 5.*.

Same with the 'host:PID:*', we grab any device that matches PID.

Filtering itself is very generic so we can probably add more elaborate
syntax like 'host:BUS.ADDR:VID:PID'. So that we can do 'host:5.*:6000:*'.

Anyway, it's implemented using a periodic timer that scans host devices
and grabs those that match the filter. Timer is started when the first
filter is added.

We now keep the list of all host devices that we grabbed to make sure that
we do not grab the same device twice.

btw It's currently possible to grab the same host device more than once.
ie You can just do "usb_add host:1.1" more than once, which of course does
not work. So this patch fixes that issue too.

Along with auto disconnect patch that I send a minute ago the setup is very
seamless now. You can just allocate some usb ports to the VMs and plug/unplug
devices at any time.

1f3870ab24 husb: support for USB host device auto disconnect (Max Krasnyansky)
I got really annoyed by the fact that you have to manually do
usb_del in the monitor when host device is unplugged and decided
to fix it :)

Basically we now automatically remove guest USB device
when the actual host device is disconnected.

At first I've extended set_fd_handlerX() stuff to support checking
for exceptions on fds. But unfortunately usbfs code does not wake up
user-space process when device is removed, which means we need a
timer to periodically check if device is still there. So I removed
fd exception stuff and implemented it with the timer.

81174dae3f Upgrade emulated UART to 16550A (Stefano Stabellini)
This patch upgrades the emulated UART to 16550A, the code comes from
xen-unstable. The main improvement was introduced with the following patch and
subsequent email thread:

http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00129.html

The changes compared to previous version are:

- change clock_gettime to qemu_get_clock

- no token bucket anymore;

- fixed a small bug handling IRQs; this was the problem that prevented
kgdb to work over the serial (thanks to Jason Wessel for the help
spotting and reproducing this bug).

- many many style fixes;

- savevm version number increased;

- not including termios.h and sys/ioctl.h anymore, declaring static
constants in qemu-char.h instead;

This patch allows to display the "Password:" prompt if we use encrypted
disk with "-nographic" option.

It also modifies management of "-nographic" to not override user's
choices for "-serial", "-parallel" and "-monitor".

When qemu has to ask a password with "-nographic" with a multiplexed
serial interface, it forces the focus to the monitor and restore
original focus after.

279e694bc7 Attempt to detect unconnected ptys (Gerd Hoffman)
This patch moves the pty char device imlementation away from the generic
filehandle code.  It tries to detect as good as possible whenever there
is someone connected to the slave pty device and only send data down the
road in case someone is listening.  Unfortunaly we have to poll via
timer once in a while to check the status because we have to use read()
on the master pty to figure the status (returns -EIO when unconnected).

Poll intervall for an idle guest is one second, when the guest sends
data to the virtual device linked to the pty we check more frequently.

The point for all of this is to avoid qemu blocking and not responding
any more.  Writing to the master pty handle succeeds even when nobody is
connected to (and reading from) to the slave end of the pty.  The kernel
just bufferes the writes.  And as soon as the kernel buffer is full the
write() call blocks forever ...

1e72d3b7ad add format= to drive options (CVE-2008-2004)
It is possible for a guest with a raw formatted disk image to write a
header to that disk image describing another format (such as qcow2).
Stopping and subsequent restart of the guest will cause qemu to detect
that format, and could allow the guest to read any host file if qemu is
sufficiently privileged (typical in virt environments).

The patch defaults to existing behaviour (probing based on file contents),
so it still requires the mgmt app (e.g. libvirt xml) to pass a new
"format=raw" parameter for raw disk images.

Originally noted by Avi Kivity, patch from Chris Wright.

f442e08b41 Slowdown SDL while minimized
When SDL is invisible/minimized, there is no need to keep calling the
VGA refresh 33 times per second.  This patch reduces in that case the
rate to 2 times per second, which should be responsive enough for the
un-minimizing event.
