wifi pci card issue in windows host.

[Dmitri Seletski]

Hello folks.
My goal is to make my pci based network card work under windows
guest.(obviously using windows drivers)

this is device i am interested in:
01:07.0 Network controller: Atheros Communications Inc. AR5416
802.11abgn Wireless PCI Adapter (rev 01)
    Subsystem: D-Link System Inc Device 3a6b
    Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+
Stepping- SERR+ FastB2B+ DisINTx-
    Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
    Latency: 168, Cache Line Size: 64 bytes
    Interrupt: pin A routed to IRQ 16
    Region 0: Memory at f9ff0000 (32-bit, non-prefetchable) [size=64K]
    Capabilities: [40] #00 [0000]
    Kernel driver in use: ath9k
    Kernel modules: ath9k

uname -a: Linux dimko 2.6.32 #4 SMP PREEMPT Thu Dec 17 02:45:45 GMT 2009
x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ AuthenticAMD GNU/Linux




below commands I have executed:
#echo "1186 3a6b" > /sys/bus/pci/drivers/pci-stub/new_id
#echo 0000:01:07.0 > /sys/bus/pci/devices/0000\:01\:07.0/driver/unbind
#echo 0000:01:07.0 > /sys/bus/pci/drivers/pci-stub/bind

last command gives:  "echo: write error: No such device"
I have "pci_stub" module loaded.

and part of dmesg:
"[ 8471.257299] wlan0: deauthenticating from 00:1e:58:b4:f6:83 by local
choice (reason=3)
[ 8471.537053] ath9k 0000:01:07.0: PCI INT A disabled"
Which i guess is ok.

than i load my guest with smth like: qemu xp32.img -pcidevice
host=01:07.0 -m 2048

I can see device in linux, i can even install driver for it, and there
are no other problems with that.
But device is not usable. Basically wireless device sees no networks,
even though my network has ESSID opened.
I was wondering if that previous "echo 0000:01:07.0 >
/sys/bus/pci/drivers/pci-stub/bind" failure can affect me?

Windows driver is freshly downloaded off dlink site. Access Point is

working, since i am connecting to it using native linux drivers.

Thanks in advance.

Unlikely you have an IOMMU in this box, so you won't really be able to
assign this device to the guest.

Can you show the output of lspci -nn -s 01:07.0 from the host?
