[Bluez-devel] [ANN] Zaurus BlueZ kernel packages for ROM v3.10

[Bluez-devel] [ANN] Zaurus BlueZ kernel packages for ROM v3.10

[Stephen Crane]

Hi,
I don't want to preempt the official packager of the Zaurus BlueZ
distribution but I couldn't wait for Sharp to get around to distributing
the kernel source and needed to try out BlueZ on the new ROM.

So I built BlueZ kernel modules from a vanilla 2.4.18 plus Marcel's
2.4.18-mh6 patch-set and a bit of tweaking to the 2.4.6 kernel config
file. 

>>From cursory testing, they seem to be ok: bluecard_cs is successfully
loaded and the latest versions of hciconfig, hcitool and sdptool all
work fine. (However YMMV, no warranty, don't blame me if your Z catches
fire, etc.)

I've uploaded them to our anonymous ftp area, along with the PCMCIA
configuration files, bluetooth and bluetooth.conf. Get them from
ftp://rococosoft.com/pub/zaurus

Installation:
* unpack the tar-ball in the /home/root/modules/2.4.18-rmk7-pxa3-embedix
directory
* run depmod -ae
* install bluetooth and bluetooth.conf in /etc/pcmcia
* run /etc/rc.d/init.d/pcmcia restart

Cheers,
Steve

the current Zaurus packages are done by Joseph Ecker and the kernel
modules are based on the deprecated bluez-kernel-2.3 package. It seems
that it is really time to have up-to-date kernel modules for the Zaurus.
Frist I don't like Joseph last choise to put the userspace tools and the
kernel modules into one big package. I like to see the kernel stuff
seperated from the userspace tools. However I have no Zaurus, so I can't
help with that. But some time ago I put some scripts in the BlueZ kernel
CVS repository which makes it possible to compile and install the
Bluetooth modules outside the kernel source. Maybe you should take a
look at it and provide some easy to install ipk packages.

The OpenZaurus project will use a 2.4.19 in future and hopefully they
include my patch. Do anyone have details about this.

Regards

Marcel

Yeah me too. Particularly because it's much easier to build the
user-space tools with a cross-compiler.

I will think about doing this if I get some time. For now, I have
uploaded the latest basic user-space binaries separately to
ftp://rococosoft.com/pub/zaurus with instructions for installing them in
the right places. It would not be too hard to write packaging scripts
for them --- indeed this is something anyone could do using the
ipkg-build script; volunteers?

We only have 2 Zauruses here (one with the older Sharp ROM and the other
with the new one) so I can't try OpenZaurus :-(

I did it : http://fichiers.xgarreau.org/zaurus/bluez_2.4.18_arm.ipk

It installs the files in the right directories, make the symlinks, try to
guess what card it is and bring device up.

Please keep me informed of new builds so that i keep the package up to date.

Just remember : plug in the card before installing the ipk or the card won't
be recognized ;-)

Re: [Bluez-devel] [ANN] Zaurus BlueZ kernel packages for ROM v3.10

[Justin Karneges]

Hi,

I'm working towards easy Bluetooth on the Zaurus.  I have a bluez GUI tool and 
qtopia dialer plugin in the works.

However, getting bluez installed was never easy.  In the past, I was using the 
ipks available at bluez.sf.net, which were never very complete.

Today, I sought to remedy this, and tried cross compiling modules and the 
libs/utilities.  I ran into a heap of trouble, and then discovered this 
thread.  I'm glad someone else is looking into this stuff too. :)

My original goal was to get this working with kernel 2.4.6, but I'm not sure 
how realistic that is.  I didn't know about the new sharp ROM until today, 
which I have now installed.  I guess it is acceptable to work with this as a 
target, and considering it comes with kernel 2.4.18, it should make a lot of 
things easier.

Xavier's package looks good.  The only flaw I think is that it does not set up 
/etc/bluetooth.

I'd like to see some secrets shared.  Could Steve or Xavier respond to me here 
or on the list, so that we can make something more official?

Re: [Bluez-devel] [ANN] Zaurus BlueZ kernel packages for ROM v3.10

[Justin Karneges]

Ok, I thought of a few more things, so to jumpstart the discussion I'll say 
them now:

> > It installs the files in the right directories, make the symlinks, try to
> > guess what card it is and bring device up.

First, what is this about card detection during ipk install?  I didn't have a 
problem with that (I inserted my card after install), and IMO there should be 
no such detection in the installer if there is.

Second, rfcomm is missing.

Third, the /dev nodes are not created.  When they are, ensure that they can 
survive a reboot.

For the future, I think hcid should be run on install and on future bootups, 
as it is required to do anything useful.  I'm not sure about sdpd though (i 
admit i'm not up on what sdp does, can someone shed some light if this is 
needed?).  Whatever daemons are run should have proper pid accounting in 
/var, so that front-ends can access them.  For instance, my GUI that modifies 
/etc/bluetooth/hcid.conf will need a way to find hcid's pid so it can send 
HUP.

Then also pin handling:  There should be a /usr/bin/bluepin that does the 
following:
  - check to see if Qtopia is up.
  - if not, echo ERR.
  - else, call my qt btpin program (let's assume it is /usr/bin/btpin)

This way the pin should properly work even during the moment where hcid is 
running but qtopia is not fully booted yet.
  
I think this should do it.  Am I missing anything?

By the way, you may see my GUI package here:

  http://www.affinix.com/~justin/zaurus-bluetooth-0.6.tar.gz

It is rather old, but works.  Unfortunately, it seems the dialer part does not 
work on the new Sharp ROM.  Argh, I'll have to fix this ..

v3.10

I'm still interrested in packaging bluez core, libs and apps for the zaurus.
When all is compiled and ready to work, i'll make another package.

I thought card detection during ipk install was a good thing to be done, if
i'm the only one wanting it, it can be removed...

I'll put rfcomm and bluepin, as soon as they are available.

That's true...

> By the way, you may see my GUI package here:

This can be added in the utils package. I think we need a kernel package, a
libs package and a utils package. But it can be further discussed...

What I'd like is to have an official "zaurus bluetooth" CVS for all of this 
stuff, that can be periodically sync'ed with bluez.  Then we can generate 
packages however we wish.  Personally, I just want one package that has 
everything.  A newbie should be able to install the "Zaurus Bluetooth 
package" and be up and running, without touching the command line.

I'm willing to create builds too, as soon as I can figure out how to actually 
do it.  It seems I'm able to build the libs / utils by hand (running 
arm-linux-gcc on each file and taking what i need.  can't seem to use 
autotools correctly ...), but I've had no luck with building kernel modules 
(they just crash when used).  What is your secret?  Got any URLs?

Also, I think I found a bug in dtl1_cs and/or bluez itself:  the card cannot 
survive a suspend.  Turning off / on the Zaurus, or simply running "cardctl 
suspend ; cardctl resume" will leave the driver in an unusable state.  
Running "cardctl eject ; cardctl insert" fixes the problem.  I'm willing to 
hack on the driver and remedy this, if I could just figure out how to 
cross-compile the modules...

This bug happens with every PC Card | CF Card I've tested.

Justin,
You can cross-compile the user-space parts of BlueZ as follows:

export CC=arm-linux-gcc
export LD=arm-linux-ld
export NM=arm-linux-nm
export RANLIB=arm-linux-ranlib
export PATH=/opt/Embedix/tools/bin:$PATH
./configure --prefix=/opt/Embedix/tools/arm-linux --host=arm-linux
make

(This is how I do it anyway.)

I disagree about the need for an official Zaurus CVS. We can put the
scripts to build the Zaurus packages in the normal place (as is done for
the rpm spec files).

Excellent, Stephen. :)

What about the kernel modules?  By the way, is dtl1_cs meant to be separated 
from the kernel?  I didn't see it in 2.4.18 even after applying 
patch-2.4.18-mh7.

[Stephen Crane]

See http://www.holtmann.org/linux/bluetooth/dtl1.html

It was only merged in 2.4.20 and 2.5.30. Perhaps Marcel needs to provide
it in his BlueZ patch for 2.4.18 and 2.4.19?

Re: [Bluez-devel] [ANN] Zaurus BlueZ kernel packages for ROM v3.10

[Marcel Holtmann]

Hi,

this package is not longer maintained, because the driver is part of the
official kernel and it is also part of my kernel patches.

> It was only merged in 2.4.20 and 2.5.30. Perhaps Marcel needs to provide

The dtl1_cs driver was in these patches from the beginning. Look at the
changelog and search for "Support for Nokia Bluetooth cards".

Regards

Marcel

Well I have a sort of heath-robinson setup here which works (but I'm not
recommending it). If you have the bandwidth, download this:

ftp://rococosoft.com/pub/zaurus/linux-2.4.18-pxa3-embedix.tar.bz2

It is a kludged-together source tree which can't build the kernel (but
manages the modules we're interested).

You can get fairly recent binaries from that site as well (they're the
ones which Xavier used, AFAIR).

Hi Justin,

the two big parts with BlueZ are the kernel modules and the userspace
stuff. The kernel stuff is the essential and the most problematic part.
And I think that we should have a package which only contains the BlueZ
kernel modules. Maybe we need different builds from the same source for
Sharp Kernel 2.4.6, 2.4.18 and OpenZaurus Kernel 2.4.18, 2.4.19.

I don't have a Zaurus, so I can't help here. Who wants to volunteer for
the Zaurus kernel package maintainer?

The BlueZ CVS module "kernel" contains a build system for building the
BlueZ kernel modules outside a kernel source tree. I am willing to
extend this as needed.

This is a known problem, but I don't have a Zaurus and so I can't test
it. On my development machine is this working without any problems.

This would be nice, if indeed we can support this on 2.4.6.  Although, I 
believe the earlier Sharp ROM has similar suspending issues related to 
cardmgr (this is what Max told me in January).  For bluetooth to work 
reliably here, we may need to offer a cardmgr upgrade.

I would like to volunteer for this, when I get a build setup working (I will 
try Stephen's soon).

What extensions do you suppose are needed?

Do you have any hint about where it may be?  Maybe the Zaurus does not send 
appropriate signals to the driver that it is shutting down?  I'd like to look 
into this, but I need some direction first.  For instance, if it affects all 
drivers, not just dtl1_cs, then either all drivers have the same "bug", or 
the bug is in the bluez core, right?

What is significant about cardctl suspend?  This will break the driver also, 
and perhaps it easier to look into this than the full pda suspend.

let us first get a BlueZ kernel package, before we talk about updating
or replacing other daemons or tools.

I hope that you don't need any extensions. Have you tried it?

As I know, that happen to all cards with a special driver (dtl1_cs and
bluecard_cs) and I don't know why.

As soon as I am able to build the modules, is there any way I can help you 
assist in debugging this?  Maybe I can sprinkle some printfs around the 
suspend-handling code or elsewhere, and we can track down at what point the 
driver fails?

Laptops are affected as well, at least those using bc3c_cs...

the bt3c_cs is another story due the needed firmware load :(
