Michael,
Prior to commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable
hotplug for pci bridges), PCI cards used to show up in the "device
tree" of OS X (System Information). E.g., on MountainLion I have:
Hardware -> PCI Cards:
Card Type Driver Installed Slot
*ethernet Ethernet Controller Yes PCI Slot 2
pci8086,2934 USB UHC Yes PCI Slot 29
ethernet:
Type: Ethernet Controller
Driver Installed: Yes
MSI: No
Bus: PCI
Slot PCI Slot 2
Vendor ID: 0x8086
Device ID: 0x100e
Subsystem Vendor ID: 0x1af4
Subsystem ID: 0x1100
Revision ID: 0x0003
Hardware -> Ethernet Cards
ethernet:
Type: Ethernet Controller
Bus: PCI
Slot PCI Slot 2
Vendor ID: 0x8086
Device ID: 0x100e
Subsystem Vendor ID: 0x1af4
Subsystem ID: 0x1100
Revision ID: 0x0003
BSD name: en0
Kext name: AppleIntel8254XEthernet.kext
Location: /System/Library/Extensions/...
Version: 3.1.1b1
After commit 99fd437dee468609de8218f0eb3b16621fb6a9c9, I get:
Hardware -> PCI Cards:
This computer doesn't contain any PCI cards. If you installed PCI
cards, make sure they're properly installed.
Hardware -> Ethernet Cards
ethernet:
Type: Ethernet Controller
Bus: PCI
Vendor ID: 0x8086
Device ID: 0x100e
Subsystem Vendor ID: 0x1af4
Subsystem ID: 0x1100
Revision ID: 0x0003
BSD name: en0
Kext name: AppleIntel8254XEthernet.kext
Location: /System/Library/Extensions/...
Version: 3.1.1b1
Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.
My command line is
bin/qemu-system-x86_64 -enable-kvm -m 2048 -cpu core2duo -M q35 \
-device isa-applesmc,osk="..." \
-usb -device usb-kbd -device usb-mouse \
-smbios file=./dmidecode.bin -kernel ./chameleon_boot \
-device ide-drive,bus=ide.2,drive=MacHDD \
-drive id=MacHDD,if=none,snapshot=on,file=./mac_10.8.img \
where "dmidecode.bin" is a custom SMBIOS table, "chameleon_boot" is
the stage-2 bootloader component of Chameleon, and on the kernel side
I have the irq-polarity patch we're currently talking about in a
separate thread
(http://lists.nongnu.org/archive/html/qemu-devel/2014-01/msg04252.html)
and also the monitor==mwait==NOP patch.
Any ideas or thoughts appreciated !
Thanks much,
--Gabriel
