Thanks

OK :), but basically what I said stands, there's no visible difference to the normal phone usage. Usually kernel features are something that you need extra functionality/applications to make use of.

Let's take a small steps at a time, and eventually (after a long time and huge workload ) a 3.x version might emerge :D

Props for Hurrian to do the hard part, I'm just enjoying being along for the ride....

Re: [Announce] kernel-plus for Harmattan

The newest build (first post) has been updated with CONFIG_WL12XX_SDIO_TEST=m.

/lib/modules/2.6.32.61-plus has also been pre-depmodded to avoid help thread user posts.

USB Ethernet client drivers, have been disabled - USB Host support on N9/50 looks like it's nonexistent, so to trim some fat, I'm removing them from the kernel image (some of them look like they're set to =y. Yikes!)

I'd also appreciate some "lsmod" dumps from N9 and N950s of different hardware revisions - pastebin them and PM them to me! I suspect some more drivers from Harmattan device prototypes still have configs enabled inside rm581_defconfig.

The source patches will be updated soon enough - I think I may have resolved the build errors encountered when CONFIG_OPPTIMIZER is enabled. Give me some more time.

That aside, as a dev I normally don't ask for contributions, but you may have heard about Typhoon Haiyan - the storm has pretty much smashed a large part of the more southern part of my country, and hundreds of thousands are in dire need of support rebuilding after the devastation. I'd appreciate it if you can put a beer or two's worth of $LC_MONETARY toward charities part of the relief efforts ;)

Thanks, I can confirm that now the patches compile cleanly ;)

Re: [Announce] kernel-plus for Harmattan

Could you please patch power kernel with these :)

OK, to get packet injection complete (mac80211 module), and to speedup injection, we need two patches to kernel/net/wireless/chan.c and kernel/net/mac80211/tx.c

Re: [Announce] kernel-plus for Harmattan

I'm on the road now but unless Hurrian is quicker to respond I'll patch those when I get home :)

Re: [Announce] kernel-plus for Harmattan

Patched, new kernel released ;)

This release includes major changes - see the first post for details!

We are slowly approaching equivalency to 2.6.34 series...

Re: [Announce] kernel-plus for Harmattan

Excellent efforts everyone! @Hurrian, how's your hand nowadays? :)

Re: [Announce] kernel-plus for Harmattan

Is there a git repo somewhere of kernel to track ?

Healed up just fine - a bit of scarring, but it's a lesson ;)

~~I think I'll add K+ v4 to my Github - it'll be there soon enough, once I diff and tag everything up nicely.~~

It's on GH - if anyone wants code added, you can fork it and send a pull request, or send me a patchfile.

The code on GitHub is ever-so-slightly newer than K+ 20131118, nothing major enough to warrant a new build though.

By the way, is /anyone/ working on getting a new GCC on top of Scratchbox? We'd eventually want to build the kernel in Thumb-2 mode, shrinking it by ~25% (2.6MB -> 1.9MB)
