@juiceme, could you please load it up on your test N9 to see what's going on? Corresponding sources are at hurrian/kernel-plus-harmattan.

If it bombs somewhere related to mac80211/wl12xx, I'll revert the commits for now, if it's somewhere else guess I'll have to dig around a bit more.
I'm glad to do that, but unfortunately it has to wait over the weekend... I left my rig at my workpalce and will be able to get to it on monday morning

systemd requires the directory /sys/fs/cgroup as a mountpoint. It doesn't exist in the kernel (2.6.35). It can't be created with mkdir either because sysfs doesn't allow that. To create the directory this patch from the 2.6.36 kernel must be backported.

http://git.kernel.org/?p=linux/kerne...9dae0071bd11f3

The following kernel config options must be selected.
General setup --->[*] Control Group support
Device Drivers --->
Generic Driver Options --->[*] Maintain a devtmpfs filesystem to mount at /dev[*] Automount devtmpfs at /dev, after the kernel mounted the rootfs (NEW)
File systems --->
< > Kernel automounter support
<*> Kernel automounter version 4 support (also supports v3)

I can confirm the device just hangs there, propably it is the sys mount that it is after. (did not try to patch it yet)

EDIT: Posted. See Page 1.

Sources patched, building.
kernel-plus 2.6.32.61-plus v5 will be built from the old local source directory, with source published as a .patch (again, sadly)

Rest assured, I'll try to match the kernel source with the Git source next time.

Details for the next release:
  • systemd support [On Harmattan!]
    (cgroupfs: create /sys/fs/cgroup to mount cgroupfs on)
  • /proc/atags exported
    Anyone want to work on porting uboot to N9/50? Start with this!
  • CONFIG_KEXEC enabled as a requirement of atags export
  • sched: Tweak sched_latency and min_granularity
  • mutex: Improve the scalability of optimistic spinning
  • net: __alloc_skb() speedup
  • KSM is also enabled, but not by default. eglibc may need to be recompiled for MADV_*MERGEABLE support. Programs linking into eglibc may need to be rebuilt. Uh-oh.

Nokia internal dev stuff can boot off MMC, NAND or USB, IIRC.

You can see some remnants of this code on the N900.

Looking forward, and very happy with the progress speed on this kernel
One thing.
I think we should include kernel drivers for Prolific PL2303 USB-to-Serial port adapter in the kernel
I believe this could possibly enable the option for USB serial console. Not quite as good as Juice's 'real' serial, but, nevertheless, usefull.

Yes, when you have R&D mode active that is part of preinit that's executed.

That would be useful, more so if you can initialize the USBSERIAL device as early as possible in order to capture all possible glitches.

Hi

I am total noobie when it comes to this kernel stuff.

I have been following this thread from time to time and concluded that this probably isn't important for me as a basic user. I don't think that I would bee needing ExFAT or NTFS on my N9, I do get Injection from N900 days, but don't know if I need it either.

What I would be interested is that does this bring any performance/stability benefits? Besides Optimizer.

Really great to see that people are still working and tweaking the N9 under the hood. Thank you guys

Well, of the top-of -my-head, stuff that are there or might soon be;
- iptables with all targets including full NAT
- wlan AP mode
- BT low energy mode
- possible performance enchancements
- bug corrections (FUSE performance, anyone?)
- all fancy new devices
- USB host mode
- etc. etc.
