How would you test it? xev ? Unfortunately during my last testing session some weeks ago the x-image was unusable (no input from touchscreen and broken keyboard-layout). I tried a fresh rebuild yesterday and it broke miserably on do_rootfs. Hopefully I'll find some time to investigate during week-end.

If 2.6.25 UDC works on PXA27x, there is nothing to do. If not, we should compare them. There are many new features in 2.6.25 (UDC, new wireless stack,...). Porting RP patches to 2.6.25 would be more productive than backporting new features to 2.6.24. Let's start with 2.6.25-rp as clone of 2.6.24-rp and comment out all failing patches with "REBASE or DROP" note. Then authors of patches will debug and fix it. > The underlying problem was linux-rp-2.6.23 in .dev had big issues with > suspend/resume.

One line reject fix for 2.6.23 or 2.6.25. Porting to 2.6.26 would require some work (GPIO code changes). I have no confirmation, that it works on akita or c7x0. Especially on C7x0 + CE-RH1, the driver is only my guess. > Anyway the 2.6.24 still needs some finishing: If you look at the > bottom of the linux-rp-2.6.24.bb you'll see there are no > mtd-module.patch for c7x0 but only for akita. Why? mtd-module.patch fixes MTD mapping of PROM, when compiled as module. I added it for machines, which were actually affected. Very minor issue, unless you want to use EN-JP dictionary database in PROM.

I personally suggested the move to 2.6.24, being desesperated by the *not resuming* device (SL-C860). Moreover Stanislav was working on Sharp remote control and the patches were only for 2.6.24. This one had also some minor glitches, like this pxa2xx_udc log I immediately noticed and reported to Richard Purdie. His opinion was "we can live with it", nobody having yet tested the usb functionality. Then some user started complaining about usb-ethernet (seems solved,isn't) and then the WPA renaming problem. I remember proposals to compile the crypt modules in kernel (hoping the size doesn't grow too much). Such things happen when too frequent changes to defconfig are done! Try mtn log --diff fo 2.6.23 and see what I mean. Anyway the 2.6.24 still needs some finishing: If you look at the bottom of the linux-rp-2.6.24.bb you'll see there are no mtd-module.patch for c7x0 but only for akita. Why?

Playing around with angstrom for a bit has highlighted a few things: Firstly the udc clock bug, which is now fixed in kernel 2.6.25 (Bug 4259), and a problem with WPA (bug 4180). I would like to tackle both to push the fixes into the standard distro. FYI I have read the wiki which details policy, but these questions apply to advice on where to start my patching work. I have currently got a building copy of angstrom (it is sooo much easier now guys, thanks so much!) Taking 4259 (pxa2xx_udc) This is fixed in 2.6.25 but I am guessing you won't want to bump the kernel version for this. If I backport the patch (might be easy, maybe not) would that be the best approach? I don't have a strong opinion on either option, but I would like at least 2 test reports from users of the chosen option (backport or 2.6.25). 2.6.24 was said to fix loads of stuff and turned out to be broken. regards, Koen ___ Angstrom-distro-devel mailing list Angstrom-distro-devel@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-devel
