Using ndisgen to create loadable module w/ broadcom on Compaq R3000z

[Kelly Black]

Hello,

I have a compaq R300z (okay, I'm sorry already!)  running
freebsd-amd64 current. I recently tried to use ndisulator for the
built in broadcom wireless and used the 64 bit windows drivers to try
to generate a loadable module for the wireless device. I have had some
trouble generating the loadable module, though. I last updated world
and the kernel on Monday.

I've tried searching the freebsd-amd64 and freebsd-current lists, and
I've tried to search using google. So far I can't find anything to
help. Has anyone managed to get this beast working?  Any help would be
appreciated. I will paste an overview of what I've tried below:

Here is the device info:
root at localhost# pciconf -lvvv
none3 at pci2:2:0: class=0x028000 card=0x12f4103c chip=0x432014e4 rev=0x03 hdr=0x00
    vendor   = 'Broadcom Corporation'
    device   = 'BCM4306 802.11b/g Wireless LAN Controller'

Copies of the driver files that I am using can be found at
http://blackk.union.edu/~black/freebsd/BCMWL564.SYS
http://blackk.union.edu/~black/freebsd/netbc564.inf.ascii
This is a 64 bit driver, and the inf file was converted to ascii using iconv. 

Here is the message I get when I use ndisgen:
Compiling stub... done.
Linking loadable kernel module... /usr/bin/ld: windrv_stub.o:
relocation R_X86_64_32S can not be used when making a shared object;
recompile with -fPIC windrv_stub.o: could not read symbols: Bad value
linking failed. Exiting.

I read through the ndisgen script to try to figure out what it was
doing. I then did this (I added -fPIC):

/usr/bin/cc -D_KERNEL -DDRV_DATA_START=BCMWL564_SYS_drv_data_start
-DDRV_NAME=BC MWL564_SYS -DDRV_DATA_END=BCMWL564_SYS_drv_data_end -I.
/usr/share/misc/windrv_stub.c -data -symbolic  -c -o windrv_stub.o
-fPIC

/usr/bin/ld -Bshareable -d -warn-common -o BCMWL564_SYS.ko
windrv_stub.o windrv.o

/usr/bin/ld -r -d -warn-common -o BCMWL564_SYS.o windrv_stub.o windrv.o

(The files windrv_stub.o and others were created when ndisgen called
ndiscvt so I just left them alone.)

When I do this the file compiles and links with no error messages. It
creates a file called BCMWL564_SYS.ko. When I try to load the file
using kldload I get these messages:

kldload: can't load /tmp/broadcom/BCMWL564_SYS.ko: Exec format error

and from the console window:

kldload: Unsupported file type
kldload: unexpected relocation type 7
link_elf: symbol windrv_load undefined

Any ideas?


Sincerely,
Kel
