Re: [Announce] [12.13.01] kernel-plus 2.6.32.59 for Harmattan
 

This is one of my long term goals as well. After I (hopefully) figure out how to get either the TI compat-wireless stuff to work and/or latest backports for hostAP mode to work, BT4 LE would be next.

I have no experience backporting, but going to try. I have gotten much farther in getting TI-compat to compile. It seems to clash with some patches in the stock kernel. There are also things from kernels 2.6.37 and back that are needed. The official patches cannot just be simply applied due to Nokia's changes.

I have a spreadsheet and what I believe are the relevant patch files I'm working from.

Hopefully I learn something and can move onto BT4. I assume IRC will be helpful there from the bluez group.

Meantime, any links to the aforementioned work by others would be immensely useful. Research is easily done in spare time.

IIRC there was some useful info. here...
http://talk.maemo.org/showthread.php?t=85118
Plus I have email addresses of some folks associated with the work if that matters.

Re: [Announce] [12.13.01] kernel-plus 2.6.32.59 for Harmattan
 

Kernel binary, modules, and source updated to kernel-plus 2.6.32.61, pulling in the LTS incremental updates.

This is a bugfix release.

Aside: I can't seem to edit the title anymore!

Re: [Announce] [12.13.01] kernel-plus 2.6.32.59 for Harmattan
 

Next time just report the first post for mods to do it :)

Hey guys,
I'm having some problems with installing the new kernel...

I extracted all files to the right place, ran depmod and edited ubiboot.conf but after the kernel selection screen I get only a black screen...

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Thanks for your work, but when I link to /lib/modules/current and flash new kernel, my N9 stuck at nokia logo after reboot. Any ideas.
Thks

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Yes, confirmed.
There is something wrong there, maybe it's the modules (as the module directory is named differently than the image, maybe there's a typo?)

I'll compile it soon and try to find out where it goes wrong.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Allright, downloaded patches and applied on clean Harmattan PR1.3 kernel tree. Everything snaps down nicely, no hanging blocks or anything, good work there. :D

Configured, Compiled, Made modules, Trial run.
--> same as with Hurrians precompiled image, device goes to hung state.
Time to do a bit of debugging, but that's later. I'll have a good night's sleep before that :)

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Not a typo - the modules directory is named as it'd be after "make modules_install", but for consistency's sake, named the zImage differently ;)

One thing to note is that I noticed that the kernel would boot... irregularly on my device. Probably 1/6 tries instead of the 6/6 tries with the previous .59 release.

For now, I'd advise everyone to use the .59 binaries until the issue is resolved. .60 and .61 are large squashed backports, something might have broke in between.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Yes I noticed that when I built the kernel, that was just a first guess really. :)
(the device behaves similarily as if it could not load modules for example, it will run in a tight loop with no UI and no reaction to the world... that was the reason I thought it might be an uname issue...)


That well explains it. I tried only to boot it twice :)
So, I'll hook up my debugging console and check what's going on there, when I have some time to do it.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

I need that :) Can you give some info on a debugging console (I pray its USB/serial available on boottime) :) ?

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Serial port, available on the N9 when you remove the SIM tray and look at the PCB in the slot. There are small golden contacts in two rows near the edge of the PCB.

The first and second from the right when you hold the device screen facing up are GND and TxD, in that order. Tho one behind the TxD is RxD, but you only need that if you want to send data to the device, for seeing boot messages hooking up to the first row contacts is enough.

To connect to your computer you need a serial-1.8vTTL level shifter - USB adapter, like this for example: CP2102-USB-2-0-to-UART-TTL-Converter, they cost under 2 eur in Ebay.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

I started thinking about this, and the way I explained it is actually very badly, so I need to try to make some ascii art for you :D

Now, imagine that you are looking at the device from above, so that it is facing away from you, display side up but so that you see the "NOKIA" text upside down. I tried sketching it for you in the picture below. The simslot is marked with a dotted line inside the device.

The contacts marked "G" are GND, "T" is TxD from the device and "R" is RxD to the device. Other pins you do not care about when using the serial console.

Also, to get some use from the console you need to enable it to output the device boot messages. This can be done two ways;

• The first way is to set the device in R&D-mode, with the flags "--enable-rd-mode --set-rd-flags=serial-console".
  This works even if you are not using ubiboot.
• The second way is to set the serial console flags via ubiboot command line injection, putting for example string "G_OS2_INIT_CMDLINE_APPENDS="console=ttyS0,115200n 8" in your ubiboot.conf file.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Here's the kernel boot log now. It seems to hang on a panic pretty nicely there :D
For some reason it seems that the kernel cannot execute "/sbin/preinit_harmattan" even though it's right on there and has the execute permissions on?

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

I just noticed that it's not aegis-neutered...
I'll recompile it with aegis patches to go.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Allright, found it :D
uploading image soonest...

------------------------------

Edit: I was way too optimistic :(

Managed to boot past the first panic but it fails at later stage...
This requires a lot of effort to go thru I guess.

------------------------------

Edit: OK now it's looking better. :)
Had a mixup of modules so the correction I made actually helped.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Allright, here's my fresh image:

http://www.swagman.org/juice/ubiboot...-plus_29102013
(md5sum=521eca00a9102b7b8a7243a08fad3171)

I have now run fairly extensive tests with it (barring of course any long-time stability tests :D)

The kernel image is compatible with the modules from Hurrian's original kernel, so you need to just download the new zImage and drop it into your /boot/ & edit ubiboot.conf accordingly.

Fixes: aegis neutering and patching the task selection priority on process wakeup.

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Many thanks, it worked flawless. You so good :D

Sorry, would i ask the full feature of .61 plus?

Re: [Announce] [13.10.27] kernel-plus 2.6.32.61 for Harmattan
 

Security and bug fixes on top of Nokia's plain old 2.6.32.54, mostly.

2.6.32 is a long term support kernel, it should be getting patches for some time.

EDIT:
First post updated with new binaries. Thanks juiceme!

Re: [Announce] kernel-plus for Harmattan
 

Getting a bit confused with all those 'power' kernels out.
This one does not include the nat and/or exfat changes?

Could we (erm you) agree to see Hurrians kernel as the new 'kp' of Harmattan? And integrate all other mods by juiceme and NielDK and e-yes, coderus, jackburton, others, ....
Or maybe nominate juiceme also as maintainer?

Just to think about it again. Openly, and to discuss.

Re: [Announce] kernel-plus for Harmattan
 

@peterleinchen i never maintained any kernel changes ever ;)

I just want to see pali and freemangordon 2 kernel god will be in kernel plus...but they not, sad

Re: [Announce] kernel-plus for Harmattan
 

Well, the .61 that Hurrian just released is a good baseline to build on.
I'll be integrating the niceties on top of that soon.

What I'm thinking is that generally I don't use dropbox that much as a distribution channel so I'm propably going to make a section on Skeiron for the kernels and patches, would that be OK for everybody?

Re: [Announce] kernel-plus for Harmattan
 

AFAIK they are more onto the N900 kernel development...

Re: [Announce] kernel-plus for Harmattan
 

It does include NAT modules, following jackburton's config changes ;)
Just read that the leaked ExFAT kernel modules are GPL'd by Samsung - I'm going to go integrate those and rebuild now.

Sounds good to me.

Yes, I knew. So disappointed

Re: [Announce] kernel-plus for Harmattan
 

Is there something specifical that you'd like to see in N9 kernel, then?
(what makes you especially disappointed?)

No from now LOL
Because u r good enough

Re: [Announce] kernel-plus for Harmattan
 

As one more addition for the stable, is anyone still working on BT4.0 support?

Re: [Announce] kernel-plus for Harmattan
 

I don't have any BT4.0LE devices, but take a look at this:
(Tested on the latest kernel-plus)

BT4.0 Low Energy is apparently supported and functional on the N9. Can anyone investigate further?

Scratch that, a bit of Googling brought something up:
BT4.0LE apparently requires BlueZ 5.x, and the 3.5 kernel.
The Bluetooth kernel subsystem will need to be ported, and BlueZ patched.

Let's see what we get.

EDIT 2:
The difference between BlueZ 4.x and 5.x is massive.
About 0 of the patches still apply to 5.x.
This will be a huge piece of work.

Re: [Announce] kernel-plus for Harmattan
 

latest kernel doesn't come with nfsd support, does it?

Re: [Announce] kernel-plus for Harmattan
 

Not yet. This is just the base port, and the other stuff needs to be ported on top of that. Depending on how I have time I might do something this evening...

Re: [Announce] kernel-plus for Harmattan
 

Odd, I seem to recall BT4/LE being confirmed as completed for the N9, & even certified! :confused:

Re: [Announce] kernel-plus for Harmattan
 

I get conflicting reports. Some say it was being worked on and close to release, others say it was some internal, scrapped thing.

Try scanning for a BT4LE-only device with the N9 - I don't have any on hand, and can't test it.

Re: [Announce] kernel-plus for Harmattan
 

No N9 with me ATM, here's some old threads I could quickly find:

Re: [Announce] kernel-plus for Harmattan
 

can anyone compile opptimizer modules for new kernels?

Re: [Announce] kernel-plus for Harmattan
 

You're confused? That reminds of the time I first got my N900 and I saw that there was a 'power' kernel available. I thought, "Oh, Maemo runs on POWER. Where do I get the ARM build?" :D

I still cringe that it's named 'power'. I'm glad Hurrian went with the name 'kernel-plus' for Harmattan.

(Sorry for the OT post BTW, felt it had to be said :o)

Re: [Announce] kernel-plus for Harmattan
 

That's for the overclocking stuff, right?

I do not really like the idea, of course it is for everyone to decide for themselves but for me N9 is fast enough with normal clocking, and I would not want to try to overclock my device.

Re: [Announce] kernel-plus for Harmattan
 

A bit of overclocking does not harm and may give you a subjective feeling that it helps (run my N900 on 850MHz with some POWERSAVE_BIAS=53 to almost always not use that max frequency).

But even I agree to juiceme in general, it is the user that activates this. So I would like to see them in the "plus-kernel".


Sounds like we found a new home for kernel-plus (or 'plus-kernel' ;))!
Would that also include a repo (git, svn, ...) to keep it easier for all of you?
