Level 15 interrupts are broadcast to all CPUs, each CPU can clear the
interrupt using the local Clear Pending register.
Update intbit_to_level table.
Don't try to raise level 0 interrupts.
Calculate pending interrupts based on the separate inputs from master
register. Setting or resetting the pending level isn't correct because of
overlap of levels.
Level 14 is always used for CPU timer interrupts, remove the property.

Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code. However,
get_fp_bit returns the bit number of the condition code, not a
bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)
Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

The ne2k is an ancient card that performs pretty terribly under QEMU. In many
modern OSes, there is no longer drivers available for the ne2k.
Switch the default network adapter to e1000. This card is more widely
suppported and performs rather well under QEMU. There may be very old OSes
that had a ne2k driver but not an e1000 driver but I think this is likely the
exception.
I think the average user is better served with an e1000 vs ne2k.

handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations. This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently. Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.
Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality. I have removed
such blocks for the appropriate targets in this patch.

kqemu introduces a number of restrictions on the i386 target. The worst is that
it prevents large memory from working in the default build.
Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on
the TSC as a time source which will not be reliable on a multiple processor
system in userspace. Since most modern processors are multicore, this severely
limits the utility of kqemu.
kvm is a viable alternative for people looking to accelerate qemu and has the
benefit of being supported by the upstream Linux kernel. If someone can
implement work arounds to remove the restrictions introduced by kqemu, I'm
happy to avoid and/or revert this patch.
N.B. kqemu will still function in the 0.11 series but this patch removes it from
the 0.12 series.
Paul, please Ack or Nack this patch.

Implement migration via unix sockets. While you can fake this using
exec and netcat, this involves forking another process and is
generally not very nice. By doing this directly in qemu, we can avoid
the copy through the external nc command. This is useful for
implementations (such as libvirt) that want to do "secure" migration;
we pipe the data on the sending side into the unix socket, libvirt
picks it up, encrypts it, and transports it, and then on the remote
side libvirt decrypts it, dumps it to another unix socket, and
feeds it into qemu.
The implementation is straightforward and looks very similar to
migration-exec.c and migration-tcp.c

A PC has its motherboard IRQ lines connected to both the PIC and IOAPIC.
Currently, qemu routes IRQs to the PIC which then calls the IOAPIC, an
incestuous arrangement. In order to clean this up, create a new ISA IRQ
abstraction, and have devices raise ISA IRQs (which in turn raise the i8259
IRQs as usual).

Hi,
After discussing the issue with Avi, Gleb and a couple others on irq,
we came to the conclusion that it is preferred to have QEMU request
features from the BIOS, rather than notifying the BIOS that it is
running on QEMU or KVM. This way memory ranges can change etc. and
an older BIOS will continue to work on newer QEMU if it receives the
info as a fw_cfg value.
This one also matches what qemu-kvm does for irq0override, except I
haven't made it configurable. I leave that as an exercise for whoever
would be interested in switching off irq0override.
Thanks,
Jes
Set irq0 override in fw_cfg, informing the BIOS that QEMU expects
override on irq0. This matches qemu-kvm, and will help sharing a
single BIOS binary.

When trying to do detached migration with exec, I found that
the monitor wouldn't always return in a timely manner. I
tracked this down to exec_start_outgoing_migration. It
appeared we were setting the fd to NONBLOCK'ing, but in
point of fact we weren't.
This bugfix should also go onto the stable 0.10 branch

Hi all,
currently the vga screen_dump code doesn't use the DisplayState
interface properly and tries to replace it temporarily while taking the
screenshot.
A better approach is to register a DisplayChangeListener, call
vga_hw_update, and finally write the ppm in the next call from dpy_update.
Testing is appreciated.

Hello,
currently when a 32 bpp cursor gets defined the result is all-black in
the areas that are not transparent (you'll get a 32 bpp cursor if you
use my previous patch to allow vmware_vga to use a 32 bpp framebuffer).
This is because the switch in sdl.c lacks a 32 bpp case.
The thing I am unsure about though is which byte is the unused one and
should be skipped, the first or the last - for the black-and-white
cursors I tested it doesn't make a difference...

Hello,
for what I can tell, there is no way for vmware_vga to work correctly
right now. It assumes that the framebuffer bits-per-pixel and the one
from the DisplaySurface are identical (it uses directly the VRAM from
vga.c), but it always assumes 3 bytes per pixel, which is never possible
with the current version of DisplaySurface.
Attached patch fixes that by using ds_get_bits_per_pixel.
This change allows to define helpers returning pointers.
This looks like a typo in original commit.
