Broadcom Wireless chips support

SaveTheRbtz · #1 November 16th, 2008, 21:38

I have notebook running freebsd-current and with broadcom wi-fi on board
PH34R# uname -a
FreeBSD PH34R 8.0-CURRENT FreeBSD 8.0-CURRENT #6: Fri Nov 14 00:21:58 MSK 2008 savetherbtz@PH34R:/usr/obj/usr/src/sys/PH34R.8 i386

PH34R# pciconf -lv | grep BCM43
device = 'BCM4310 broadcom wireless 1490 (dell)'

wireless currently running via ndis

Will there be support for this wireless chipset in future?

graudeejs · #2 November 17th, 2008, 00:55

I very much doubt.
Broadcom aren't willing to give drivers to free community

Kitche · #3 November 17th, 2008, 01:19

I m pretty sure that drivers would be ported sometime from OpenBSD but highly doubt it will be officially Broadcom.

try this driver

prudhvi · #5 November 17th, 2008, 20:02

Hi, Paradox

Your driver is working like charm

I tried it on 7.0-RELEASE will give it a short in 8-CURRENT today

Thanks

richardpl · #6 November 18th, 2008, 00:33

It will not work on CURRENT because of VAP aka multi-BSS

paradox · #7 November 18th, 2008, 09:03

>prudhvi
driver not mine
i take it from perforce repository
my be iam write own driver

Today I've tried dragonflybsd bwi drivers on my HP 6715s laptop... But it didn't worked out with my card =(
First of all in pciconf my card listens as
device = 'BCM4310 broadcom wireless 1490 (dell)'
but has BCM4312's id:
bwi0@pci0:48:0:0: class=0x028000 card=0x1371103c chip=0x431214e4 rev=0x02 hdr=0x00

Back to driver:
My card isn't in supported macs revisions list... So i've got error something like "MAC rev 13 is not supported"
not a big deal, added to see if it helps.

# vi bwimac.c
static const uint8_t bwi_sup_macrev[] = { 2, 4, 5, 6, 7, 9, 10, 13 };
Now driver says "unsupported 11G PHY, rev 9"
This is worse, but I can give it a try:
# vi bwiphy.c
if (phyrev > 9) {
device_printf(sc->sc_dev, "unsupported 11G PHY, "
"rev %u\n", phyrev);
return ENXIO;
}
That time i've got "bwi0: can't initialize 0th TX ring"
And what i see in bwi_init_tx_ring64? (Yeah my card has 64bit bus)

static int
bwi_init_tx_ring64(struct bwi_softc *sc, int ring_idx)
{
/* TODO:64 */
return EOPNOTSUPP;
}
=(( I can't write it without knowledge of BWI_TXRX64_RINGINFO_ADDR_MASK, BWI_TXRX64_RINGINFO_FUNC_MASK and etc. values =(

full output of driver below

So there are couple of questions
1) to FreeBSD commiters: bwi driver is now in OpenBSD,NetBSD and even in DreganFlyBSD. Is there so big problem to port it?
2) to bcm hackers: does anybody know where i can get some kind of reversed engineered driver manual or some kind of helpsheet for firmware bits?

show me yr

is yr bsd 64bit? as example amd64

which platform the DF ?

SaveTheRbtz · #13 November 19th, 2008, 19:38

1) it'll be CURRENT in an hour.
2) i386

paradox · #14 November 19th, 2008, 19:56

too strange

SaveTheRbtz · #15 November 19th, 2008, 20:59

No, 64bit it's about bus space
bwi0: 64bit bus space
there are three kinds of bus space in BCM43xx: 30bit 32bit and 64bit

It's not connected with operating system arch in any way

allbanddxer · #16 November 19th, 2008, 22:46

This is so interesting that I should stumble on this bwi driver, I have been searching for a solution and gave a OpenBSD a try just because they had that driver, but I could not adjust to OpenBSD. I downloaded bwi.01.tar.bz2 that was posted by Paradox but I don't really know what to do with it. After I install it, how do I configure that module to start? Do I add bwi_enable="YES" in /boot/loader.conf... and then setup the network device like any other card? If it matters, I am using 7.0 Release i386.

SaveTheRbtz · #17 November 20th, 2008, 00:40

I've tried to compile driver against -current and as richardpl said it has some issues with new 80211 stack. So every one who is willing to try bwi need to downgrade to at least 7-STABLE

allbanddxer
# cd bwi.01
# make
# make install
# kldload bwi_v3
# kldload if_bwi

And can you tell model of ur BCM from
# pciconf -lv
?

Hey thanks for the install steps SaveTheRbtz, here is the output you requested.
bwi0@pci0:2:0:0: class=0x028000 card=0x033a1154 chip=0x431814e4 rev=0x02 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM43XX Broadcom 802.11b/g'

SaveTheRbtz · #19 November 20th, 2008, 01:12

Your card is in "known devices" list, so, if revision is right it should work just fine

Code:

	{ PCI_VENDOR_BROADCOM, 0x4301,"Broadcom BCM4301 802.11 Wireless Lan" },
	{ PCI_VENDOR_BROADCOM, 0x4307,"Broadcom BCM4307 802.11 Wireless Lan" },
	{ PCI_VENDOR_BROADCOM, 0x4311,"Broadcom BCM4311 802.11 Wireless Lan" },
	{ PCI_VENDOR_BROADCOM, 0x4312,"Broadcom BCM4312 802.11 Wireless Lan" },
	{ PCI_VENDOR_BROADCOM, 0x4320,"Broadcom BCM4306v1 802.11 Wireless Lan"},
	{ PCI_VENDOR_BROADCOM, 0x4321,"Broadcom BCM4306v2 802.11 Wireless Lan"},
	{ PCI_VENDOR_BROADCOM, 0x4325,"Broadcom BCM4306v3 802.11 Wireless Lan"},
	{ PCI_VENDOR_BROADCOM, 0x4324,"Broadcom BCM4309 802.11 Wireless Lan" },
	{ PCI_VENDOR_BROADCOM, 0x4318,"Broadcom BCM4318 802.11 Wireless Lan" },
	{ PCI_VENDOR_BROADCOM, 0x4319,"Broadcom BCM4319 802.11 Wireless Lan" }

Or he/she can download bwi from perforce (older files revisions, because latest one I tested are broken) and it have support for vap. Just open correct branch ;-)

For firmware: bwifw.ko use same one already posted

SaveTheRbtz · #24 November 20th, 2008, 18:39

If anyone needs... here is bwi_v4 firmware kernel module sources. (based on 4.80.53.0)
http://opticomspb.ru/~savetherbtz/fr...ifw_v4.tar.bz2
Specs for it can be found here:
http://bcm-v4.sipsolutions.net/

Does anybody want to write driver? =)
