Please excuse the noobness of my question! But what does this kernel do that others don't? Does it make the 3D camera work in custom roms or? Again, please excuse my noobishness as it looks like everyone else on this thread knows what's going on and I don't

THANKS!!! :laugh:

It is a native built kernel, no cross compiling.
Using ARM processor to make ARM binaries.

Here is a recovery I've pieced together, based on TWRP 2.7.1.0 for shooteru, work for shooter. But selinux is not working, so no jb roms I think

TWRP 2.7.1.0_JCFunkMOD

jcfunk · Jul 26, 2014

twrp2.7.1.0_JCFunkMODv2.img

Here is an update to the recovery, removed more shooteru stuff.

Well, that was an adventure! I flashed your mod recovery, v1. Used rashr, good recommendation. I'm not used to twrp. So formatted to f2fs, it worked. But after that couldn't flash a Rom, because kernel(your b.t.mod) couldn't read SELinux contexts, whatever that means. Well, made mistake of wiping /system in the process. Had to flash mac kernel to be able to flash Rom. So until you got everything working, no more testing for me

selinux is used in jb and newer roms. Its a security thing. Just don't know why installers are not working.

Is the buttered toast kernel NOT configured for ksm?

F2fs version might not be, was a rush to put together, we will be releasing a more put together version

reviving this thread, as it seems the most appropriate place to post this.
I had forgotten how cool it is to see a kernel building on-phone, hadn't made a working chroot for my evo since getting it.
now that my desktop pc went kablooey, I dug out aide and put an ubuntu 14.04 chroot on the evo to keep myself entertained.
the ubuntu 14.04 updated udev whines about no devtmpfs, so I had to rebuild the kernel.
thus this post.
thanks jcfunk for reminding me phones can indeed build even if not as fast as x86 hardware. my old optimus v only OC'd to 806MHz single-core, the evo is much more effective (and armv7 ubuntu is easier to use than armel debian.)

Not really dead, updated source and working on getting to compile with 4.9
and since Ubuntu and linaro are together. The arm version is linaro's gcc. It's has a hell of a time errors in 3.0 kernel not in new kernels with same code. Don't know why.

by the way, if you hadn't seen, xserver xsdl on play (open source) for slick gui chrooting.

Really just use terminal chroot, will checkout the app. I truely believe a native build is better then cross compiled

i get a charge from building on device. plus it's a lot more useful than setting up my old Toshiba laptop with comparable specs to the evo.

that x server is pretty sick, once i got everything set up right in the chroot i can watch YouTube in chromium-browser even.
never had smooth streaming with a vnc.

Maybe you can post image or guide how to setup. I don't have time to figure it out. [emoji3]

basically open the xserver app, then in chroot

Code:

env DISPLAY=$(ifconfig | sed -En 's/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'):0 startxfce4&

to start xfce4 .
substitute other GUI startup at will for startxfce4. the rest of the mess is just to grab the local ip so you don't hafta type it in. //server doesn't like 127.0.0.1 #actually it's cool but was a buttwumpus to find simple directions for local X port forwarding from a non-running system (chroot)

u7se this for forwarding localhost:6000 over ssh:
kind of working but inconsistent, wifi most consistent

Code:

ssh -X -L 6000:localhost:6000 you@localhost "startxfce4 &"

in chroot terminal.
you is your user/root, startxfce4 can be swapped for your personal choice.
gotta add shmem lib from xserver github and tmpfs at /dev/shm for chromium.
devtmpfs on in kernel or find a usable way around udev.

easier to use terminal but i like gimp and stuff too.
shouldn't derail your thread too much....
should mention whatever arm-linux-gnueabihf- came with 14.04 compiled johnnyslt's kitkat mirage shooter kernel all friendly-like and no issues running it.

Not a derail good info for people to build on phone.

bigsupersquid · Jan 21, 2015

added ssh forwarding instructions for xserver above. no network connection needed.

Had problems, I'm using core Ubuntu img which didn't have xfce4 installed. Install and run your command, I get xserver running already.

it's the x server app running, mine says that when it connects anyway.
instead of xce4, dwm is ultra light, but you have to use key shortcuts to open anything. lxde seems to want bigger screen. gnome is heavy but i may try it anyway.... maybe compiz, it's open gl.
xfce works decent, that's why i installed it.
//whoops, had extra & at end of ssh line that broke it. ssh tunnel better'n net tunnel anyway.
today only wifi working, wtf.

Here is a test version, need people test and tell me if it's ok.
BT_JCFunkMOD-vTEST.zip

Here is a version without aroma installer. BT-RLS17.9_JCFunkMOD-test_no-aroma.zip
