[KERNEL][DEV][ICS][TW-Only] M1 Kernel V5 [2012-06-19]

Hi All,

Who I Am: My name is Mauro Ribeiro I'm from Brazil and I HATE long walks its gets even worst if its on the beach. I have 15+ years of experience on Linux, 5+ on Java. I do work as a Network Admin for a Large Brazilian Company.

Why: It comes my time to help this nice community that gaved me so much.

What: Linux Kernel 3.0.15 based on Samsung sources with Speedmod Patch's.
This kernel DOES NOT HAVE MMC_CAP_ERASE so it SHOULD be safe.

Its basicly Speedmod K3-3 Kernel with A TON OF MODULES. There are modules for USB Ethernet, USB Sound, USB Serial and Much much more.

BE CAREFUL WHEN YOU LOAD MODULES, MODULES USES MEMORY AND MEMORY IS A PRECIOUS RESOURCE.

MODULES ARE AT: /data/local/modules

IF YOU DON'T KNOW HOW TO LOAD A MODULE THIS KERNEL IS NOT FOR YOU.

ITS NOT A DAILY DRIVER KERNEL HAS ALOT OF STUFF. ITS FOR TESTING.

Be patient when I say that I'm working on something, My computer is a P3 with 1 Gig of ram. So everything takes time and I have to work too.

I'm 100% open to sugestions. Wanna chat about this kernel? I'm mdrjr @ freenode! come on IRC and chat with me. Leave this topic for development only.
I'm always at #project-voodoo .. come and chat.
DON'T PM ME. COME AND CHAT

Attached file is a ZIP that SHOULD BE FLASHED THRU CWM!

kernels are at:
http://www.mdrjr.net/kernel

v5:
Now that modules aren't on initramfs anymore
We have USB Serial and USB Wifi adapters!
YAY!
Let your BackTrack / Wifi Sniffing go
Also, moved files from XDA to my Hosting.

v4:
Added some missing stuff.
Build another TON of modules.
To make kernel smaller and friendly on RAM. Modules from now on will be at /data/local/modules.

v3:
Fixed some errors most of the stuff is pre-built inside the kernel now.
Removed USB-Serial Support. Ask me if you need this back.

v2:
Some idiot (ME) forgot that hardcore disable's logging for his kernel I have it enabled now.
Enabled logging and more logging.

v1:
Samsung ICS update 3 + Speedmod Patch K3-3.
Compiled with a tons of modules
modded initramfs

PS: Sorry for the typo on the date or.. i'm posting from the future.

Thanks goes to:
Linux (Linus)
Google (Android)
Samsung (For the phone)
Francisco Franco (For his work that I stoled... sorry, just few lines of code I'm using on this kernel)
Speedmod (For releasing all his work too and making this possible)
Chainfire (Plenty of instructions around and his work for android is HUGE)
Supercurio (Greate guy talked couple of lines with him. And his awesome job on Sound/Video on android)
If I'm missing someone else.. PM and I'll give you credit.

You should not include the modules in the initramfs. The initramfs is always in memory, so this way the modules waste the precious RAM even if not loaded. It is better to have them on the large emmc partition.

BTW, the kernel's copyright license is GPL, a link to the binary should always be accompanied by a link to the source.

Its on the OP KERNEL IS SPEEDMOD KERNEL! Get the source from there. Its the same source.

And again on OP its a NOT A DAILY DRIVEN KERNEL. ITS FOR TESTING ONLY.

I don t know how to load a module...
I want anyway that the usb module for attach a fiio E 17 is loaded by default.
How to?

I don't know what Chipset your USB DAC uses ;( sorry.

Can't load module.

insmod says

'unknown symbol in module or invalid parameter'

Also I found this, it details what modules the Nook Colour Dev team took to enable usb DAC.
Looks like we're missing a module?

insmod /drv/snd-hwdep.ko
insmod /drv/snd-rawmidi.ko
insmod /drv/snd-usbmidi-lib.ko
insmod /drv/snd-usb-audio.ko

From this page



Also, @mdrjr where can I find you on freenode?

and Yes, I got that issue as well... rebuilding stuff now.

nice job

but too many logging may cause battery goes faster?

Yes.. it may cause battery and RAM usage.

Another xda dev pointed me to this dmesg output from an s3 when connecting a c media dac

This is something like we'll see on success.

Drivers are built-in on V3. You shouldn't need any modules to get it working.

I tried appending this code below in /system/etc/asound.conf

pcm.!default {
type plug
slave {
pcm "hw:1,0"
}
}

This is pretty much what others have been doing (same code to get USB devices working under linux)

And I tried various other ways of doing the same thing but ultimately got the output below each time :-( You can see I used a standard PCM 16bit stereo 44kHz wav file.



app_197@android:/sdcard # alsa_aplay -D plughw:1,0 test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

not sure if I'm missing something in asound.conf or if we're missing support in another library.


EDIT:

I've been poking around other sources that have USB audio support working.
One suggestion is that the order of module loading matters, and I wonder how we are affected since you compiled all the drivers into the kernel.
The drivers in order of insertion others are using are as follows
snd-hwdep.ko (this is part of speedmod kernel)
snd-rawmidi.ko
snd-usbmidi-lib.ko
snd-usb-audio.ko

Don't know about the order of these but pretty sure they're essential

snd-mixer-oss.ko
snd-pcm-oss.ko

Loading sequence does matter that's the main reason to leave it to kernel handle.
When you build modules as built-in kernel keeps the loaded all time at ram so you don't have to worry about loading.. its all there.

I'll check and see if snd-mixer-oss and snd-pcm-oss are there...

Meanwhile can you run alsa_aplay -D plughw:1,0 -vvv test.wav
and give us the output? getting that extra verbosity may help.
