Simply ask for a small window size. When the widgets don't fit in gtk

Each display gets its own tab. Tab switching continues to work like it

display is present as it will get ctrl-alt-2 assigned and the vtes are
shifted by one.
The vte tabs simply get the size of the vga tab then, with whatever
cols and lines are fitting in. I find this bahavior more useful than
resizing the qemu window all day long.

qapi: zero-initialize all QMP command parameters
In general QMP command parameter values are specified by consumers of the
QMP/HMP interface, but in the case of optional parameters these values may
be left uninitialized.
It is considered a bug for code to make use of optional parameters that have
not been flagged as being present by the marshalling code (via corresponding
has_<parameter> parameter), however our marshalling code will still pass
these uninitialized values on to the corresponding QMP function (to then
be ignored). Some compilers (clang in particular) consider this unsafe
however, and generate warnings as a result. As reported by Peter Maydell:
This is something clang's -fsanitize=undefined spotted. The
code generated by qapi-commands.py in qmp-marshal.c for
qmp_marshal_* functions where there are some optional
arguments looks like this:
bool has_force = false;
bool force;
mi = qmp_input_visitor_new_strict(QOBJECT(args));
v = qmp_input_get_visitor(mi);
visit_type_str(v, &device, "device", errp);
visit_start_optional(v, &has_force, "force", errp);
if (has_force) {
visit_type_bool(v, &force, "force", errp);
}
visit_end_optional(v, errp);
qmp_input_visitor_cleanup(mi);
if (error_is_set(errp)) {
goto out;
}
qmp_eject(device, has_force, force, errp);
In the case where has_force is false, we never initialize
force, but then we use it by passing it to qmp_eject.
I imagine we don't then actually use the value, but clang
complains in particular for 'bool' variables because the value
that ends up being loaded from memory for 'force' is not either
0 or 1 (being uninitialized stack contents).
Fix this by initializing all QMP command parameters to {0} in the
marshalling code prior to passing them on to the QMP functions.

The Python "except Foo as x" syntax was only introduced in
Python 2.6, but we aim to support Python 2.4 and later.
Use the old-style "except Foo, x" syntax instead, thus
fixing configure/compile on systems with older Python.
Character backend open hasn't been fully converted to the Error API.
Some opens fail without setting an error. qmp_chardev_add() needs to
detect when that happens, and set a generic error. Explain that in a
comment, and inline error_is_set() for clarity.
Using error_is_set(ERRP) to find out whether a function failed is
either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP
may be null, because errors go undetected when it is. It's fragile
when proving ERRP non-null involves a non-local argument. Else, it's
unnecessarily opaque (see commit 84d18f0).
The error_is_set(errp) in qemu_chr_new_from_opts() is merely fragile,
because the callers never pass a null errp argument.
Make the code more robust and more obviously correct: receive the
error in a local variable, then propagate it through the parameter.
char: Use return values instead of error_is_set(errp)
Using error_is_set(errp) to check whether a function call failed is
fragile: it breaks when errp is null. Check perfectly suitable return
values instead when possible. As far as I can tell, errp can't be
null there, but this is more robust and more obviously correct

s390x/kvm: hw debugging support via guest PER facility
This patch makes use of the hw debugging support in kvm (provided by the guest's
PER facility) on s390. It enables the following features, available using the
gdbserver:
- single-stepping
- hw breakpoints
- hw watchpoints
This patch allows to insert and remove sw breakpoints using the QEMU gdbserver
on s390 as well as to interrupt execution on a breakpoint hit when running
with KVM enabled.
Whenever a software breakpoint is inserted, common code calls kvm ioctl
KVM_UPDATE_GUEST_DEBUG. As this method's default on s390 is to return an error
if not implement, the insertion will fail. Therefore, KVM also has to be
updated in order to make use of software breakpoints.
When restoring the previously saved instruction in
kvm_arch_remove_sw_breakpoint(), we only restored one byte. Let's use
the sizeof() operator to make sure we restore the entire instruction.
While we are at it, let's remove the duplicate definitions of DIAG 501
and replace its size (used when reading/writing the instruction) with
a sizeof() operator to make the code self explaining and less error-prone.
Make use of the new s390 adapter irq routing support to enable real
in-kernel irqfds for virtio-ccw with adapter interrupts.
Note that s390 doesn't provide the common KVM_CAP_IRQCHIP capability, but
rather needs KVM_CAP_S390_IRQCHIP to be enabled. This is to ensure backward
compatibility.
Introduce a common parent class for both cases, where kvm and non-kvm
can hook up callbacks. This will be used by follow-on patches for
adapter registration and mapping.
We now always have a flic, regardless of whether we use kvm; the
non-kvm implementation just doesn't do anything.

ps2: set ps/2 output buffer size as the same as kernel
According to the PS/2 Mouse/Keyboard Protocol, the keyboard outupt buffer size
is 16 bytes. And the PS2_QUEUE_SIZE 256 was introduced in Qemu from the very
beginning.
When I started a redhat5.6 32bit guest, meanwhile tapped the keyboard as quickly as
possible, the screen would show me "i8042.c: No controller found". As a result,
I couldn't use the keyboard in the VNC client.
Previous discussion about the issue in maillist:
http://thread.gmane.org/gmane.comp.emulators.qemu/43294/focus=47180
This patch has been tested on redhat5.6 32-bit/suse11sp3 64-bit guests.
More easy meathod to reproduce:
1.boot a guest with libvirt.
2.connect to VNC client.
3.as you see the BIOS, bootloader, Linux booting, run the follow simply shell script:
for((i=0;i<10000000;i++)) do virsh send-key redhat5.6 KEY_A; done
Actual results:
dmesg show "i8042.c: No controller found." And the keyboard is out of work.
Every error source is checked separately. The second function is only
called when the first one succeeds. Both functions are free to pass
their argument to error_set(). Because error_set() asserts no error
has been set, this effectively means they must not be called with an
error set.
The qapi-generated code uses the error API differently:
// *errp was initialized to NULL somewhere up the call chain
frob(..., errp);
gnat(..., errp);
Errors accumulate in *errp: first error wins, subsequent errors get
dropped. To make this work, the second function does nothing when
called with an error set. Requires non-null errp, or else the second
function can't see the first one fail.
This usage has also bled into visitor tests, and two device model
object property getters rtc_get_date() and balloon_stats_get_all().
With the "accumulate" technique, you need fewer error checks in
callers, and buy that with an error check in every callee. Can be
nice.
However, mixing the two techniques is confusing. You can't use the
"accumulate" technique with functions designed for the "check
separately" technique. You can use the "check separately" technique
with functions designed for the "accumulate" technique, but then
error_set() can't catch you setting an error more than once.
Standardize on the "check separately" technique for now, because it's
overwhelmingly prevalent.

qapi-visit.py: Clean up a sloppy use of field prefix
generate_visit_struct_fields() generates the base type's struct member
name both with and without the field prefix. Harmless, because the
field prefix is always empty there: only unboxed complex members have
a prefix, and those can't have a base type.
qapi: Replace start_optional()/end_optional() by optional()
Semantics of end_optional() differ subtly from the other end_FOO()
callbacks: when start_FOO() succeeds, the matching end_FOO() gets
called regardless of what happens in between. end_optional() gets
called only when everything in between succeeds as well. Entirely
undocumented, like all of the visitor API.
The only user of Visitor Callback end_optional() never did anything,
and was removed in commit 9f9ab46.
I'm about to clean up error handling in the generated visitor code,
and end_optional() is in my way. No users mean no test cases, and
making non-trivial cleanup transformations without test cases doesn't
strike me as a good idea.
Drop end_optional(), and rename start_optional() to optional(). We
can always go back to a pair of callbacks when we have an actual need.
qapi: Normalize marshalling's visitor initialization and cleanup
Input and output marshalling functions do it differently. Change them
to work the same: initialize the I/O visitor, use it, clean it up,
initialize the dealloc visitor, use it, clean it up.
This delays dealloc visitor initialization in output marshalling
functions, and input visitor cleanup in input marshalling functions.
