So I read what I could on 2.6 difference with 2.4, and it looked like my
easiest choice was to modify the bestcomm code to export a couple tables and
its API functions. I found that kallsyms has almost all of the functions I
needed to resolve (with 'T' next to them), but they were still not working.
I added EXPORT_MODULE(TaskBDReset) and similar declarations in the bestcomm
api code, but that still didn't do the trick for me. So what is the trick?
I think I'm on the right track, I can insmod a module that my driver needs,
see kallsyms get updated, and access the functions directly in my driver. I
hope I'm close to doing something similar with the bestcomm functions, can
anyone offer me some advice on what else I need to do?
Thanks.

Subject: Using bestcomm in an external module (MPC5200B to be exact)
I'm writing a driver for a TI codec attached to the MPC5200B PSC3 codec
lines on a Lite5200b. It's an external module, and I'd like to use Bestcomm
with it. I've already tried a bunch of horrible things to get it to work.
I could say it's close, but by close I mean the FEC still runs, my stuff
doesn't.
1. Can the Bestcomm I/F be used by an external module, or is the module
required to be built in if built-in drivers use Bestcomm? TasksInitAPI (no
so bad) and TasksLoadImage (yeah, bad) aren't really supposed to be called
more than once from what I've read, and the kernel loads them for ethernet
and ATA (no disk in my system if that matters).
2. If it can be used by an external module, how would I do it? I've tried
compiling the source into my module and replicating the initialization the
kernel does in addition to my own stuff. It's not too bad, though I don't
get any interrupts yet.
The LTIB from Freescale includes AIC23 and AC97 drivers that use Bestcomm.
I built my kernel with them set as modules, and they had the same unresolved
problems that my driver has on insmod, so I'm pessimistic. If someone could
put me out of my misery one way or another, I'd appreciate it.
Thanks.

Hi Andrey,
Thanks for the reply. I did notice that a few weeks ago and was waiting for
the patch state to be changed from "New" to "Accepted". Can you give me
more details on how you found out bestcomm won't be included in 2.6? The
latest downloadable LTIB from Freescale for the Lite5200b includes bestcomm
in several places, and the mpc52xx fec driver uses it, along with the ATA
driver that Sylvain provided a patch for.
As for http://www.246tNt.com/mpc52xx/, it's been coming up "page not found"
for me for those same few weeks when I've tried it off an on, and
www.246tNt.com just has a Welcome line in it.

Yes sorry about that ...
server crash ... hard ... we kinda lost a lot. Hopefully =20
gitbits.246tNt.com which host the bestcomm stuff is on another server.
I also have a newer / cleaner version of the patch. I've sent it to some
dev (Dale, Andrey & John) for comments (any news on that guys ? or are you
just fine with it ?)
But anyway, it's mainly internal cleanup and adapting drivers

The latest ltib isn't based on your latest but then again your latest
was never public:).
So is your git tree uptodate? If so then I will look at putting
together some patches to it. I have an ata update and also an ac97
driver. My goal is to have the best version in the public and ltib
just a copy of it.

Yes. What's in there and not in main streams adds quite a lot to
arch/ppc ... So
MPC5200 should be adapted to arch/powerpc first and then those changes.
And since
no-one did that yet and I haven't done it yet either ... (I must admit I

How can I help getting the mpc5200 migrated to the powerpc tree?
I should have some time to help with this.
After we get it migrated we can get the bestcomm code in and
the various drivers that use it.

and I will try again to get you one.
