Call For Review: Sonics Silicon Backplane(SSB) driver
Weongyo Jeong
I've written a Sonics Silicon Backplane driver which is widely used for
Broadcom Wireless driver that bwi(4) can use this driver though it has
its own routines in it.
I don't have any knowledge to write a bus driver like this so I'm not
sure my approach is correct. Please review!
You can download a driver at:

Hi there Weongyo!
I´d like to know .. will it compile under 8.0-RELEASE or -STABLE?
Should I try your module instead of bwi(4)?
And just in case you find it usefull, in ssb_pci.c, {
PCI_VENDOR_BROADCOM, 0x4315, "Unknown" }, is actually a 'Broadcom
Wireless b/g (BCM4315/BCM22062000)'. I have one .. here you´ll find my
pciconf -lcvb usinf bwi(4) with parado´s firmware:
http://pastebin.com/f1f40900c
#bwi0@pci0:12:0:0: class=0x028000 card=0x000b1028
chip=0x431514e4 rev=0x01 hdr=0x00
# vendor = 'Broadcom Corporation'
# device = 'Broadcom Wireless b/g (BCM4315/BCM22062000)'
# class = network
# cap 01[40] = powerspec 3 supports D0 D1 D2 D3 current D0
# cap 09[58] = vendor (length 120)
# cap 05[e8] = MSI supports 1 message, 64 bit
# cap 10[d0] = PCI-Express 1 endpoint max data 128(128) link x1(x1)
bwi0: PHY: type 5, rev 1, ver 6
bwi0: RF: manu 0x17f, type 0x2062, rev 2
Hope that help :)
Best Regards
Gonzalo

Yes it should be.
> Should I try your module instead of bwi(4)?
No. ssb driver is a kind of bus driver that it's not a wireless driver
so can not use. But I'm working on new driver (aka bwn(4)) for
replacing bwi(4) that it uses v4 firmware (latest firmware) and supports
more H/Ws. It's almost done that it works to associate with AP and
pings for RX/TX but not public yet. When it's available let you know
for testing. :-)

Good to know !
I´ll install FreeBSD 8.0 tomorrow and give your driver a go and as
soon as I have something, I´ll report back to you :)

That´s even better than I expected because bwi(4) simply doesn´t
support my hardware!
So what shoudl I do?
Load it alonside bwi(4)?
Just load it and see what I get on /var/log/messages and dmesg and report back?
And since you are writing a new driver, can I help to make it work
with ACPI from the get go?

One more thing can we add BCM4315 to the list of known devices. Please
see the attached patch.

Hi,
I have a 'Broadcom Wireless b/g (BCM4315/BCM22062000)' and I tested your
work. After loading the ssb kernel module, dmesg gives
ssb0: <Unknown> mem 0xf4000000-0xf4003fff irq 19 at device 0.0 on pci6
This card doesn't work with the bwi driver so I'm looking foward to test
your bwn driver.

Please wait until I'm ready. It'd not take long time.

Applied in my local tree. Thanks you for reporting.
