I am a very beginner with this.The attachment is the diff between the
cm-kernel and modifications based on it.thx~!
Maybe helpful~

Are you saying you got the cm-kernel booting a 6.x radio using this patch?
Can you make a diff using
Code:
diff -urN
yes,i think so ; )
this is the diff file,but with local kernel project based on cm-kernel eclair
You 'think' so?
...
It would be nice to see new radio work with CM. Can you provide more details if you really got this to work?

Can you do a
Code:
diff -urN
so that we can apply it using
Code:
patch -p0 < diff.txt
source code i modified for porting it to new Radio,please check it first.
i will send my source code tonight(Beijing Time,now daytime),because i am working in my office.
my english is no so good, sorry ~~

When you create that diff file, instead of using 'diff -r ' can you use 'diff -urN'
Also, have you tried booting this?
i never worked on cm-kernel, but i think your patch will make your phone boot. but for the new radio, only these modification could not make the android layer working properly.
and i think you should not use cm-kernel as your start or base. Cyanogen didn't do much thing special at the kernel level, you could know this by viewing his git log or by a diff. and the modification and patches Cyanogen applied will become obstruction when you would do some serious work.
all the patches or modification Cyanogen applied to cm-kernel can be applied after we make a clean kernel good enough.
official source code is a better start. if you could work on official sources, we could work together since I have made a kernel .29 which can support aosp ROM, and working on kernel .32 and prepare to add some supports for HTC specified functions now.
i use android 2.1 using my boot.img with kernel i built and sanpei's system.img.
i just want to post some source code for who want to build the kernel for new radio,not
test too much. And i just make the cm-kernel boot up with new Radio,not do too much.
thx!
I have said now i can not post the diff. for I am in office,i'll post it when i am home.OK?

Sorry, I didnt see that you couldn't post the diff. Thanks youngzi.
I send the diff.patch between my source code and CM-kernel ,but i do not sure this can help you to do the work.hope this useful.thx~~
i send the diff user diff -urN, you can get it. but i do not know whether i do it in right way.~

Perfect. Thanks.
u r welcome : )
Could you post a working kernel? Just a boot.img-kernel would be fine...thanks
If you guys have a 6.x compatible CM kernel ready for testing, please alert me as I am willing to upgrade and have a go at testing it. if there are specific list of stuff i need to test, please include a list.

i send the kernel i built. u can try to make bootimage use this kernel
and this is very very unstable.
Im so sorry if this is in the wrong place but im a developer working on my first kernel and my question is only going to get some help by the most elite ROM dev's out there.
Ok so i got the BFS patch for the kernel im currently working on which is 2.6.32.9. Of course the patch is meant for a mainline kernel and not an Android kernel so i went through the patch file and applied the patch by hand, it was a pretty smooth process the diffs in the bfs patch were all the same code just wouldn't apply because all the line numbers were off. My first attempt bombed so i must have made some mistakes it was my first time patching by hand! Anyways took another crack and recompiled the kernel after every file patched so i could basically debug compiling problems well it all went smooth.
Heres the problem though, kernel compiles fine with out bfs checked, with it checked it compile a hell of alot of the kernel, but it eventually fails and it make no seance after my investigation of things. Here is my error
Code:
drivers/built-in.o: In function `mmc_wait_for_req':
lowmemorykiller.c:(.text+0xd2b3c): undefined reference to `wait_for_completion_io'
make: *** [.tmp_vmlinux1] Error 1
I found the decleration for wait_for_completion_io in kernel/sched.c the only thing i changed in sched.c was to at line 1 and it was basically to include sched_bfs.c, if the scheduler was seleted in the config, heres the patch stuff for sched, all i did was add the three lines to check if bfs was set in the config and then added the #endif at the bottom
Code:

At the end of sched.c it starts exporting the functions and wait!!!! the first function it exports looks like this!

*/

}

So maybe sched isnt exporting any functions anymore after the inclusion of sched_bfs.c into it? i dont know all i know it i didnt touch lowmemmory.c and im sooo close to getting BFS but this is boggling me!! Maybe there is a conflict in kernel options im not aware of? I turned off all c groups and the default scheduler.
I wont paste my .config here nothing annoys me more than that, heres a link to a gist of it on github (just like pastbin for thos not in the know lol) bfs enabled .config and here is my sched.c and my lowmemmorykiller.c! Any help would be awesome there are so many people patching bfs into there androif kernel so im hoping this is a common type of problem
EDIT if i remove the mmc drivers it finishes the compile, but i kind of need these have to sleep now ill experiment more, if neone has any ideas about what the heck is goin on id love to know
did you ever fix this? i ran into the same error. a quick google search got me this and it seems to be working. ill post later if it actually works.
edit: succesfully built tdm's gingerkernel with -ck patchset with this. working on bobzhome's kernel now
Sorry this is way late man!! I have been doing alot of hardware hacking as of late, my android stuff especially kernel modding has been pushed to the the side.
Anyways how did BFS turn out any speed improvements? Maybe ill see if I can patch it into cm9 if theres and good reason for that
I am getting this same error after adding bfs to my kernel.. the link you gave is 404. Any one who worked with bfs that can provide some insight, that would be greatly appreciated. Thanks

You can get BFS working adding these lines in <kernel-path>/kernel/sched_bfs.c

Hi All,
I am currently trying to compile kernel module for a local echo driver in ICS. I got success while trying the same in GB but doing so in ICS the echo driver is not get compiled to KO object
I got below errors while compiling

Hi all,
Today I've decided to build CM11 for my DIFRNCE DIT1010 tablet.
I'm trying to get started by building CWM first, since I'm new at this, and also because I figured I'll need that to flash CM in the end.
I know there's the clockworkmod builder website, I've tried that, but it apparently gave me a CWM for loganrelte aka Galaxy Ace 3.
And I also thought I wouldn't learn much by using that website. (sorry, I don't mean to slack off that great tool)
So I've been following the guide on xda-university, ran into some problems which I've been able to fix so far, but now I need help.
Running make -j4 recoveryimage starts off with: (I've translated this from Dutch)
Code:
/home/harm/bin/out/target/product/DIT1010/obj/APPS/SignatureTest_intermediates
find: ‘src’: no such file or directory

Code:

So I followed the link it gave me there, which tells me to "Follow the CM Build Guides for your device with the change explained below."
I've searched, but there are no build guides for my device.
Can anyone help me fixing my problem?
Thanks in advance.
Okay, so I've downloaded my kernel from http://crewrktablets.arctablet.com/?wpfb_dl=1473,
extracted it, and I've put the kernel.img in /home/harm/bin/device/DIFRNCE/DIT1010.
Now I get a different output:
Code:
build/core/tasks/kernel.mk:91: **********************************************************
build/core/tasks/kernel.mk:92: * Kernel source found, but no configuration was defined *

build/core/tasks/kernel.mk:94: * BoardConfig.mk file *
build/core/tasks/kernel.mk:95: **********************************************************
What's the TARGET_KERNEL_CONFIG variable? I believe it's a path to somewhere, but I don't know where to point it to?
I am trying to build some kernel modules for a Tronsmart MK808ii but Tronsmart have not provided the config (No proc/config.gz) after some messing about I have managed to get some kernel modules to load (I have the Init and Exit pointers in the right place). My first aim is to allow the device to read usb cdroms and iso files for which I need to load isofs.ko cdrom.ko and sr_mod.ko
Actually things go pretty well except there appears to be a misalignment between struct gendisk in the module and kernel. when the genhd driver dereferences gendisk->part0 i get an oops. Looking at the code the only definable length object before part0 seems to be disk_name
In order to be more precise about what's happening and to determine the relative alignment of structures between my kernel and the supplied one I need to be able to disassemble the original kernel which I've extracted from the eeprom - ony problem is that neither file nor objdump know what to do with this image, so I'm presupposing it has some sort of header on it so the bootloader can find the image. The Image starts with KRNL$
Does anyone have an idea of how vmlinux image can be extracted from this rom image?
