Kernel Patchs Download

[Ripley]

Where can I find the kernel patches for the zaurus?  Hmm...  more precisely to build the 3.5.3 OZ kernel (2.4.18-rmk7-pxa3-embedix).  Is there any place where the kernel developpers put their patches or is it spread around the world?  I'll have some time to put on the kernel (for the zaurus), but I don't want to reinvent the wheel...

Which device is this? Presumably the 5500 or 5600 seeing the kernel you want?

Let me know and I'll post the .bb file which gives the URLs and order to apply the patches.

Even better would be to setup an OpenEmbedded/BitBake system and then it'll do it all for you,

I have a 5600 and have acces to a 5500 at the job (I think, maybe it was swap with another 5600...)  I downloaded BitBake and tomorow, I'll setup my cross compiling env.  Is it better to have the gcc 2.95 or 3.3.3?  An ex-coworker build it for xscale (and srongArm) (available at arm.nihilisme.ca).

And what about the work in progress for the kernels, is there a "Central  Information Association" or everybody works in his little basement?

2.9.5 is required to build the 2.4.18 kernels, 3.xx is required to build *everything* else.

I actually think that 3.3.4 is the current default - just let it build itself and it will download and build what you need (though you may possibly need the 2.95 toolchain - I don't remember I'm afraid - it's downloadable from somewhere on openzaurus.org).

And what about the work in progress for the kernels, is there a "Central Information Association" or everybody works in his little basement?

Look on the OpenZaurus.org website - on the bottom right hand side there are links to the porting efforts for 2.6.x to the various platforms. There's also the mailing lists & IRC.

Does anyone know where to get the pxa patches for more recent kernels (2.4.31?)?  I also want to know why the pxa patches are not merge into the "standatd" kernel.

The 2.4.18 kernel is a little but old and I would like to try to have a more recent kernel.

2.4 is a dead end. I don't recommend hacking on it anymore. Better help us finishing 2.6. The most prominent reasons for the arm stuff not ended up in mainline is mainly that no one was interested in taking the great pains necessary to do it during 2.4. Some things were too intrusive anyway. Thanks to RMK and a lot of other contributors (including famous OZ kernel hacker Richard Purdie), 2.6.13 contains very good arm support, basic machine support for almost every Zaurus is included, it just needs finishing some drivers for a couple of models (including the 5600 and the 6000).

looking forward to a finished 2.6 and working OZ on the 6k.
  Any one tried 2gig sd or mmc on an OZ 2.6 based system yet?

[Ripley]

You're right, I'd better use my time on the 2.6 kernel.  I only have acces to a 5600 (and maybe a 6000 when it won't be used anymore/replaced at work).  So, the John Lenz' patches are the good starting point?  His webpage isn't update since june, is there more updates?  Is there another place to look for acive development information/bug tracking/... for the Zaurus kernel?

The #1 source is the OpenEmbedded meta data repository. This is where the most recent kernel patches which are not yet in mainline can be found. If you're serious with hacking on 2.6 for poodle, drop us a note to kernel-discuss@handhelds.org, openzaurus-devel@lists.sf.net, and if you have a chance, visit us on #oe in freenode IRC.

What are the nick of the guys working on poodle?  A guy there told me to wait for RP (isn't he working "only" on the sl-cxxx zaurus?).  I manage to install 2.6.13-mm3, but I can't realy poke around and I have some question about change fom 2.4 (like the mtd partitions change).

[Mickeyl]

RP is more or less your best bet. He mainly works on the SL-Cxxxx (as that's the only hardware he has), however, he is responsible for pushing lots of SharpSL general stuff into mainline, so he is in the position to comment on what's necessary to do and to comment on your patches. John Lenz works on poodle and collie, but he is never on IRC, you have to contact him via E-Mail. Dirk Opfer is the primary Sl-6000 kernel worker, he may comment on kernel issues as well. His nick is do13.
