Up to now "select without attention" was handled the same way as
"select with attention". According to
http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR53C9X.txt
select without ATN sends the CDB (Command Descriptor Block) directly,
whereas select with ATN sends one message phase byte
followed by 6, 10, or 12 command phase bytes.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu

Hello,
the real world issue is that the hardware allows sends up to 2600 bytes,
and for some reason FreeBSD sometimes sends frames larger than the
ethernet frame size (102+1460 is the maximum I have seen so far),
overflowing the on-stack tx buffer of the driver.
Independent of that, the code should avoid allowing the guest to
overwrite the stack.
This is a minimal patch to fix the issue (you could leave out the size
change of the buf array as well, networking still seems to work either
way). Obviously there are better ways to handle it, but a proper fix IMO
would involve first getting rid of the code duplication and given the
number of patches pending for that code I see no point in working on that now.

-watchdog NAME is now equivalent to -device NAME, except it treats
option argument '?' specially, and supports only one watchdog.
A side effect is that a device created with -watchdog may now receive
a different PCI address.
i6300esb is now available on any machine with a PCI bus, not just PCs.
ib700 is still PC only, but that could be changed easily.
The only remaining use of struct WatchdogTimerModel and
watchdog_add_model() is supporting '-watchdog ?'. Should be replaced
by searching device_info_list for watchdog devices when we can
identify them there.
Also fixes ib700 not to use vm_clock before it is initialized: in
wdt_ib700_init(), called from register_watchdogs(), which runs before
init_timers(). The bug made ib700_write_enable_reg() crash in

- you can't have load/save functions out of sync
- will allows us to have new interesting commands, like dump <device>, that

- Just now, the only added type is arrays, but we can add structures.
- Uses old load_state() function for loading old state.

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.
