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 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 from the public version on my git tree to this newest/cleaner version is a 15 min work ;) Sylvain ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

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.

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. Also, did you ever get a liteb board? If not send me your address and I will try again to get you one.
