[Bluez-users] bt3c_cs time out - no firmware loaded?

[Krisztian Mark Szentes]

Hi

I have trouble with the 3COM Cardbus bluetooth card on a Powerbook Titanium (a 
powerpc notebook). I patched the 2.4.20 kernel with the mh-6 patch (and the 
benh patch which does not collide). I haven't found any hint on the list yet.

With a USB bluetooth adapter (hci_usb) everything works fine. I have a 
wonderful RFCOMM communication to a Nokia 6310 and I can get on the internet 
via GPRS.

When, however, using a 3COM Bluetooth adapter, I get 
connection timed out errors.
like:
tomcat:/home/m# hciconfig hci0 reset

or:

What's wrong? Am I supposed to use another bluefw executable?

[Bluez-users] bt3c_cs time out - no firmware loaded?

[produktivIT]

Hi

I have trouble with the 3COM Cardbus bluetooth card on a Powerbook Titanium 
(a powerpc notebook). I haven't found any hint on the list yet regarding 
my problem.

I use a Debian unstable system, I patched the 2.4.20 kernel with the mh-6 
patch (and the benh patch which does not collide). With a USB bluetooth 
adapter (hci_usb) everything works fine. I have a wonderful RFCOMM 
communication to a Nokia 6310 and I can get on the internet via GPRS.

However, using a 3COM Bluetooth adapter ("3COM Bluetooth Wireless PC Card, 
Version 2.0, 3CRWB6096, M/N: SL-1022, PN:10043851-01 Rev:AA), I get 
connection timed out errors.

Hmm, you should see bluefw messages before HCI dev 0 registered.
I guess you'd need to ping Marcel on that one.

is this a SMP enabled kernel? The driver have some problems if you run a
SMP kernel. Try to disable it.

I observed cardmgr to cause a line
cardmgr[xxx]: executing: 'modprobe bt3c_cs' line

I deleted the /sbin/bluefw symlink to /usr/sbin/bluefw to see if it gets 
invoked, which gives:
bt3c_cs: Failed to exec "/sbin/bluefw pccard 03f8".

in /proc/ioports bt3c_cs shows up at 000003f8-000003ff

if I manually call /usb/sbin/bluefw pccard 03f8 it gives no error; but it 
does not touch the /etc/bluetooth/firmware/BT3CPCC.bin file either.
I tried the bluez-bluefw both in version 1.0-1 and 0.9-2 (powerpc) and 
compiled 1.0 from source, but the firmware still does not even get 
touched, let alone loaded. And I get no bluefw messages in syslog.


Any hints?

Mark

P.S. The /sbin/bluefw symlink is not included in the Debian packages but 
the kernel module loads this and not /usr/sbin/bluefw.

No, single processor. powerpc.
# CONFIG_SMP is not set

I hope the card itself would work all right; but as far as I can tell the 
firmware does not get loaded. I hope this is not a powerpc arch problem.

I missed something in your previous mail :(

You're using a Powerbook and the 3Com is currently not supported on the
PowerPC architecture. The Kernel side of the driver should work fine
(not tested), but the bluefw have no code to load the firmware. Take a
look at the mailing list archive for this problem.

Marcel

Thanks, I found the relevant part (by Edd Dumbill):

"Second, the bad news, there's still x86-arch specific code in there, for
the bt3card stuff.  At least ppc does not have sys/io.h. " 

There must be some uniform way to access I/O of a Cardbus PC-Card on the 
more common arch plattforms. (I did not find any - perhaps there is 
none??) Ben, can you please have a look at the code? (Sent by separate 
mail.)

Greets

Mark
kind of astonished, I chose the 3COM card explicitly according to the BlueZ 
hardware compatibility list, I could also have chosen the Xircom or Anycom 
cards; they would probably have saved a lot of messing around.
Perhaps you could correct 
http://www.holtmann.org/linux/bluetooth/bt3c.html
in order to reflect the missing powerpc support.

Furthermore, you could also enhance the hardware support page by adding 
vendor co-operation information like linuxprinting.org does. I saw Anycom 
directly links to Marcel's homepage. A simple sorting of the list 
according to driver openness etc. would just suffice

If you search through the mailing list archive, you will find a posting
from Max that suggested the same thing. I included it into the list and
removed it the at same day, because I am not the person who should
decide which company is Linux friendly and which is not. Let the list
and the driver source code talk for themself. And you mention the Anycom
driver. I have this driver already finished over half a year ago, before
I got the rights to publish it under GPL.

Hrm... The problem isn't simple. You are just not supposed to tap IOs
that way from userland, especially since PPC arch doesn't have anything
like "PIO" instructions. The IO space of your card is actually mapped
somewhere in physical memory, that "somewhere" not beeing generally
available to userland.

Can you tell me more about the card ? Is it a 16 bits PCMCIA device or
is it a cardbus (PCI) one ? Why can't you tap the IOs solely from within
a kernel driver ?

Ben.

this is a 16 Bit PCMCIA card. We need to load the firmware from
userspace, because we can't distribute it within the kernel driver due
the legal issues. At the moment we don't even distribute the firmware
file with our userspace firmware loader program.

Can't you do some kind of ioctl or /proc entry to the card's driver
to pass it the firmware from userland and have the actual IO code in
the kernel ?

an ioctl is not possible at that time, because we need the firmware
loaded before we can initialise the Bluetooth HCI device. And I don't
want to use the /proc for this kind of stuff. We hopefully will have a
unified interface for this in 2.5 with request_firmware() call and the
sysfs. See current discussion on LKML.

Then a /proc entry or a temporary /dev entry will be the only sane
solution for 2.4 I'm afraid...

if you don't see any other solution to work around, this device will be
not supported on the PowerPC platform.

And probably many others...

direct IO port access is really an x86 thing... 

Note that if the cardbus bridge actually sits on the main PCI bus and uses
"legacy" PIO addresses, it is possible to do something, though I hate it ;)

You can call the sys_pciconfig_iobase syscall to retreive the physical base
address where the IO ports of a given PCI bus are mapped.

By passing that the bus number where the cardbus bridge lives on, you can
then use the resulting value to mmap /dev/mem and actually access those
IO ports.

When actually implementing inx/outx in userland, I strongly suggest you do
what the kernel does in asm/io.h for ld/st_le16, so you get byteswapped
access for 16 bits, and have proper eieio barriers.

That syscall should have the following syntax:

#define IOBASE_IO		2

syscall(200, IOBASE_IO, bus_number, 0);

Ben.

OK.

I am fed up with the card, I bought it almost year ago and hoped it would 
some time become easier to use. I chose it over the Xircom and Anycom 
parts because its antenna looked neat. In the meantime, I also bought a 
USB device which explicitely stated Linux compatibility on the 
manufacturer's web site (Epox).
I'm thinking about 

(1) asking 3COM for permission, or 
(2) returning it to 3COM's headquarters or 
(3) publicly destroying it and putting up a video or
(4) sell it to a modern slave (Windoze user) and donating the money to 
Debian

Marcel, can you give me a hint whom I should contact for (1)? 

Salut

Mark

P.S. Maybe I should do (1), (2), (3) AND (4)   :-))

I have not a PowerPC platform for testing, so I can't write any code at
the moment. But your proposal looks very ugly and I don't want to go
this way for 2.4. I will wait until the firmware stuff is accepted by
Linus and then try to port the current driver to the new architecture.

I got a contact at Cebit this year, but I never found the time to write
an email to him according the firmware stuff and the new card Version
3.0 (which is not working with this driver). You can contact him if you
like. His name is Brent Nixon (brent_nixon(at)3com.com).

It is quite ugly, though not as ugly as hard coding the IO ports like
some ppl do ;) It's also the only proper way to access the IO ports
from userland regardless which PCI host bus they are on. We added this
syscall for the sake of XFree initially.
