Do we have a working patch for the latest 3.2 Wheezy kernel?

Hi guys,

today I wanted to compile a 3.2 kernel from the wheezy repo (3.2.23-1 to be precise). So, as usual I grabbed a patch
from here
https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/linux/archlinuxarm.patch
and tried to apply it ... with little success.

Somehow the patch seems to be quite outdated: still using boot_params instead of atag_offset, missing a lot of mach types, adding iConnect support although Debian seems to support it already (board-iconnect.c?) and a lot of other annoyances.

Am I missing something? Is there a better Debian patch somewhere or should I try to fix this one?

Edit: Ok, now I finally found davygravy's patch for 3.3.x
https://www.dropbox.com/sh/nwt2kbvetvgvroo/iUjYHep7VX/Kirkwood/kernel/patches
I'll check if that one will perform better with Debian's 3.2.

Vlad,

I ran into the same problem with that patch compiling 3.2.18. And I could not find any patch that works. So I went back to the Arch Linux ARRM July 2011 patch for goflex Net and goflex Home (it does not have the Pogoplug V4, though). It would be nice to have a good up-to-date patch for Wheezy we can all use!

I've attached the file here in case you want to take a look.

Update: I did not see you've already found one before posting :-)

Thanks, bodhi!
I totally agree that it would be nice to have a regularly updated working Wheezy patch, especially when Wheezy will officially become stable. I know that some people here are working to get 3.5 and 3.6 kernels working, which is surely a good thing, but not also shouldn't forget about people who want to use older but more stable kernels.

With davygravy's patch and the patch you attached we already have some basis to start with. I'll see, if I can find some spare time to try to create a proper Wheezy patch.

Kurlon has submitted this patch for 3.5.1:
https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/linux-kirkwood/archlinuxarm.patch

Attached patch is archlinuxarm_07_01_2011.patch (Goflex Home/Net only) with fixed NAND badblocks. Patched vanila 3.2.28 kernel builded and booted from sata.

Vlad,

I've tried Davy's patch with 3.2.26. The new machine types were rejects. Was that because 3.3 vs 3.2? Any idea why? thanks!

Regarding patch rejected the machine_types, l've figured out the reason: the code were just different enough that patch has problem reconcile the diffs so it rejected the file. I manually modify the machine types and it built pass that.

However, the build encountered other problems in davy's patch, I ended up modifying several of the kirwood devices setup files in order to build. And it did build OK now.

Hi bodhi,

does it also boot without

General setup -> Embedded System -> Enable
Patch physical to virtual translations at runtime -> Disable

and setting PHYS_OFFSET to 0x00?

Hi Vlad,

I have not tried that yet! I set these values so that I can use the same 3.2.x build on my other plugs, which still have Jeff's original UBoot on them. If you want to confirm that, I could rebuild another version without these parameters and try them?

Hi Vlad,

You got me curious, so I rebuilt 3.2.26 without these 3 parameters. It boots on my Dockstar which has Jeff's UBoot!!!

I wonder if somebody has sneaked in a patch to the 3.2.x kernel. Could you try to build your 3.2.x and confirm this?

@Vlad,

Update on the Dockstar booting with no L2 workaround: I found that the kernel boots only intermittenly only. But it does boot a few times among several tries! and it would not boot at all on the GoFlex Home.
