spice-display should not call the ui/console.c functions dpy_cursor_define
and dpy_moues_set with the SimpleSpiceDisplay lock taken. That will cause
a deadlock, because the DisplayChangeListener callbacks will take the lock
again. It is also in general a bad idea to invoke generic callbacks with a
lock taken, because it can cause AB-BA deadlocks in the long run. The only
thing that requires care is that the cursor may disappear as soon as the
mutex is released, so you need an extra cursor_get/cursor_put pair.

The function job_cancel_async() will always cause an assert for blockjob
user resume. We set job->user_paused to false, and then call
job->driver->user_resume(). In the case of blockjobs, this is the
block_job_user_resume() function.
In that function, we assert that job.user_paused is set to true.
Unfortunately, right before calling this function, it has explicitly
been set to false.
The fix is pretty simple: set job->user_paused to false only after the
job user_resume() function has been called.

This is mandated by the ohci specification. It tells at 6.4.4 on page 104
that for transfer descriptors that are retired with an error the done
queue interrupt counter is cleared as if the interrupt delay field of the
descriptions were zero.
Before this change, error conditions were handled similarly to the
successful condition which is especially troublesome for control transfers.
Some drivers (e.g., the AmigaOS-one) as well as the example code in the
spec, set the setup stage with an interrupt delay of seven (which means no
interrupt). This is fine under normal conditions, because one usually
doesn't want to be notified about the completion of this stage. However, if
an error occurs in this stage, these drivers will not get notified with the
current implementation. The fix addresses this by following the spec more
closely. Also, otherwise, the ability to set interrupt delay to seven would
be useless.
Note that Linux drivers that I looked at don't seem to be affected as they
set six as the interrupt delay presumably for the reason that they won't
get notified otherwise.

- prep machine is a fictional machine, so has no specifications. Which
devices can be changed/added/removed without impact? Are interrupts
correctly mapped?
- prep firmware (OHW) has support only for IDE drives (no SCSI).
Booting from IDE has been broken approximatively 3 years ago, and nobody complained.
- OHW is limited on IDE boot to a specific set of OS loaders.
These operating systems are of the 2004 time frame.
- OHW can use -kernel. Linux kernel freezes a long time after PS/2 mouse
detection, and then screen becomes garbage. This was already broken in
QEMU v2.7, 2 years ago, and nobody complained.
On the other side:
- 40p is a real machine, so emulation can be checked against
hardware specifications
- OpenBIOS has support for SCSI block devices, including 40p LSI adapter
- OpenBIOS can start mostly all Linux kernels (including recent ones)
and recent operating system (like NetBSD 7.1.2)

This proposal introduces a new IRQ number space layout using static
numbers for all devices, depending on a device index, and a bitmap
allocator for the MSI IRQ numbers which are negotiated by the guest at
runtime.
As the VIO device model does not have a device index but a "reg"
property, we introduce a formula to compute an IRQ number from a "reg"
value. It should minimize most of the collisions.
The previous layout is kept in pre-3.1 machines raising the
'legacy_irq_allocation' machine class flag.
