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.

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.

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.

Instead of calling the IOAPIC from the PIC, raise IOAPIC irqs via the ISA bus.
As a side effect, IOAPIC lines 16-23 are enabled.

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.

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,
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.

Searching for "inspiration" to convert another device to qdev, I got
