Hi,
I'm testing OS X on the q35 tree, and it seems to work quite nicely
so far.
However, with the addition of "usb-ehci1" in the latest round of
updates, I've started experiencing hangs during OS X boot.
First, what works:
With the following command line (usb items on the last line):
bin/qemu-system-x86_64 -enable-kvm -m 2048 -cpu core2duo \
-M q35 -L q35-seabios/out -monitor stdio \
-device isa-applesmc,osk="our...<magic apple smc key>...Inc" \
-kernel ./Chameleon_RC5_Trunk_Binaries_r668/i386/boot \
-netdev user,id=hub0port0 -device e1000,netdev=hub0port0,id=eth0 \
-device ide-drive,bus=ide.0,drive=MacHDD \
-drive id=MacHDD,if=none,snapshot=on,file=./mac_10.6.img \
-device ich9-usb-uhci1 -device usb-kbd -device usb-mouse
I get a working OS X guest, with the following USB related bits in
'info qtree':
...
dev: gmch-pcihost, id ""
MCFG = 2952790016
irq 0
bus: pcie.0

dev: ich9-usb-uhci1, id ""

rombar = 1

command_serr_enable = on

dev: usb-kbd, id ""
port = <null>
full-path = on
addr 0.2, port 1, speed 12, name QEMU USB Keyboard, attached
...
If I replace:
-device ich9-usb-uhci1 -device usb-kbd -device usb-mouse
with the generic default:
-usb -device usb-kbd -device usb-mouse
I get a hang at boot time. OS X (SnowLeopard) prints the following
USB-related warning/error to its console:
USBF: 2.557 AppleUSBEHCI[0xffffff80056c5000]::CheckSleepCapability - controller

The following USB bits show up in 'info qtree':

Note how both the keyboard and mouse are now under 'ehci1', rather than
under one of the 'uhci' entries, e.g. uhci1 like in the working example
earlier on.
When I try to start with ehci1 only, with the following USB command line
items:
-device ich9-usb-ehci1 -device usb-kbd -device usb-mouse
I get an error from qemu:
speed mismatch trying to attach usb device QEMU USB Keyboard to bus usb-bus.0
The simple presence of EHCI1 as configured by "-device ich9-usb-ehci1"
will prevent OS X from booting (with the above-mentioned "controller will be
unloaded across sleep" warning). If added all by itself, it looks like
this in qtree:
...
dev: gmch-pcihost, id ""
MCFG = 2952790016
irq 0
bus: pcie.0
type PCI
dev: ich9-usb-ehci1, id ""
maxframes = 128
addr = 03.0
romfile = <null>
rombar = 1
multifunction = off
command_serr_enable = on
class USB controller, addr 00:03.0, pci id 8086:293a (sub 1af4:1100)
bar 0: mem at 0xfebf1000 [0xfebf1fff]
bus: usb-bus.0
type usb-bus
...
I don't know if/how I can tell '-device usb-kbd' to connect under usb-uhci1
specifically (in the case where both ehci1 and uhci[1-3] are present), so I
did not have a chance to try that.
I wonder what specifically about the way ehci1 is added to the device tree
make it not work properly on OS X -- any ideas for what may be wrong, or
what else I may try, would be much appreciated !
Thanks,

PS. For comparison with some real Apple hardware, here are the usb bits from
lspci on an old first-generation MacBookPro from 2006:
