  • Replace -no-virtio-balloon by -balloon ...
    7d4c3d53 
    We want to do (at least) two things to the virtio-balloon device:
suppress it, and control its PCI address.  Option -no-virtio-balloon
lets us do only the former.  To get the latter, replace
-no-virtio-balloon with

    -balloon none   disable balloon device
    -balloon virtio[,addr=str]
                    enable virtio balloon device (default)

Syntax suggested by Anthony Liguori.

    In order to parse multiple instances of the same param=value pair,
introduce get_next_param_value which can pass back to string parsing
position after reading a parameter value.

  • Add serial number support for virtio_blk ...
    bf011293 
    [brought forward to current qemu-kvm.git]

This patch implements the missing qemu logic to
interpret a '-drive .. serial=XYZ ..' flag for
a virtio_blk device.

The serial number string is contained in a
skeletal IDENTIFY DEVICE data structure and
this structure is made available to the guest
virtio_blk driver via pci i/o region 0.

  • net: Real fix for check_params users ...
    0aa7a205 
    OK, last try: 8e4416af broke -net socket, ffad4116 tried to fix it
but broke error reporting of invalid parameters. So this patch widely
reverts ffad4116 again and intead fixes those callers of check_params
that originally suffered from overwritten buffers by using separate
ones.

  • Create qemu-option.h ...
    d3f24367 
    This patch creates a new header file and the corresponding implementation file
for parsing of parameter strings for options (like used in -drive). Part of
this is code moved from vl.c (so qemu-img can use it later).

The idea is to have a data structure describing all accepted parameters. When
parsing a parameter string, the structure is copied and filled with the
parameter values.

  • augment info migrate with page status ...
    9f9e28cd 
    This patch augments info migrate output with status about:
* ram bytes remaining
* ram bytes transferred
* ram bytes total

This should be enough for management tools to realize
whether or not there is progress in migration. We can
add more information later on, if the need arrives

[v2: fixes bytes_transferred type]

  • Refactor how display drivers are selected ...
    993fbfdb 
    My previous commit, f92f8afe,  broke -vnc (spotted by Glauber Costa).  This
is because it's necessary to tell when the no special display parameters have
been passed and default to SDL or VNC appropriately.

This refactors the display selection logic to be less complicated which has
the effect of fixing the regression mentioned above.

  • Hardware convenience library ...
    1ad2134f 
    The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

  • net: Fix -net socket parameter checks ...
    ffad4116 
    My commit ea053add broke -net socket by
overwriting an intermediate buffer in the added check_param. Fix this
by switching check_param to automatic buffer allocation and release, ie.
callers no longer have to worry about providing a scratch buffer.

  • monitor: Rework API (Jan Kiszka) ...
    376253ec 
    Refactor the monitor API and prepare it for decoupled terminals:
term_print functions are renamed to monitor_* and all monitor services
gain a new parameter (mon) that will once refer to the monitor instance
the output is supposed to appear on. However, the argument remains
unused for now. All monitor command callbacks are also extended by a mon
parameter so that command handlers are able to pass an appropriate
reference to monitor output services.

For the case that monitor outputs so far happen without clearly
identifiable context, the global variable cur_mon is introduced that
shall once provide a pointer either to the current active monitor (while
processing commands) or to the default one. On the mid or long term,
those use case will be obsoleted so that this variable can be removed
again.

Due to the broad usage of the monitor interface, this patch mostly deals
with converting users of the monitor API. A few of them are already
extended to pass 'mon' from the command handler further down to internal
functions that invoke monitor_printf.

At this chance, monitor-related prototypes are moved from console.h to
a new monitor.h. The same is done for the readline API.

  • Stop VM on ENOSPC error. (Gleb Natapov) ...
    428c5705 
    This version of the patch adds new option "werror" to -drive flag.
Possible values are:

report    - report errors to a guest as IO errors
ignore    - continue as if nothing happened
stop      - stop VM on any error and retry last command on resume
enospc    - stop vm on ENOSPC error and retry last command on resume
            all other errors are reported to a guest.

Default is "report" to maintain current behaviour.

  • graphical_console_init change (Stefano Stabellini) ...
    3023f332 
    Patch 5/7

This patch changes the graphical_console_init function to return an
allocated DisplayState instead of a QEMUConsole.

This patch contains just the graphical_console_init change and few other
modifications mainly in console.c and vl.c.
It was necessary to move the display frontends (e.g. sdl and vnc)
initialization after machine->init in vl.c.

This patch does *not* include any required changes to any device, these
changes come with the following patches.

Patch 6/7

This patch changes the QEMUMachine init functions not to take a
DisplayState as an argument because is not needed any more;

In few places the graphic hardware initialization function was called
only if DisplayState was not NULL, now they are always called.
Apart from these cases, the rest are all mechanical substitutions.

Patch 7/7

This patch updates the graphic device code to use the new
graphical_console_init function.

As for the previous patch, in few places graphical_console_init was called
only if DisplayState was not NULL, now it is always called.
Apart from these cases, the rest are all mechanical substitutions.

  • add a -vga none cli option (Stefano Stabellini) ...
    c2b3b41a 
    currently there is no way to fully disable any graphic card device for
the PC architecture.
You can have no graphical output, thanks to -nographic, but you would
have the VGA device connected to your PCI bus anyway.
There is already a convenient -vga option to choose between std, cirrus
and vmware; this patch add the new option "none" to select no graphic
card at all.

  • Add -rtc-td-hack option to fix time drift with RTC on Windows (Gleb Natapov) ...
    73822ec8 
    After my last patch to fix interrupt coalescing was rejected
on the basis that it is too intrusive we decided to make the
fix much more localized and only fix the problem for RTC time
source. Unfortunately it is impossible to fix the problem entirely
inside RTC code like Andrzej proposed since Windows reads RTC
register C more then once on each time interrupt so it is impossible
to count reliably how many interrupt windows actually handled.
Proposed solution is localized to I386 target and is disabled by
default. To enable it "-rtc-td-hack" flag should be used.
