[KERNEL][04 APR] skullcap-voodoo #11 [VoodooSnd v7,color,more...] i9010 for Captivate

This is a kernel based on GT-i9010 JL1 Armani source.

Compatible with 2.2 and 2.2.1 ROMS.

I ran the Andromeda 2.0 ROM (currently running Andromeda3) as my daily driver and liked the kernel the ROM came with (UrsaMinor) for speed, smoothness, and battery but had a couple issues, like in call volume, so I got inspired to contact the guys on TeamKomin, grab the 9010 source play with it. This kernel is what I ended up with. It's been working great for me for a while now so I figured I'd share it.

Normal disclaimer about you flashing at your own risk <here>.

Boosted in call volume

for either the help with source or the help with questions.
If I've missed anyone I apologize and will add you if you remind me.

I have had the best success with the UGJL2 modem here in the north eastern US. YMMV.

UPDATE: Thanks to perosredo for doing some testing of modems with the kernel. His results are here Modem Test Spreadsheet

Looks like JK4 will work nicely with the kernel as well, at least from a speed perspective. IMO GPS is still a little better with JL2 though.

I have a KB1 kernel working as well with similar tweaks that I might post as well if anyone is interesting in testing it.

One last thing I guess... I do this as a hobby, it's not my life.

Reserved cause everyone else does it.

V11:
SD card read ahead set to 4096 for speed improvement as found here

V10:
Voodoo sound v7

V9:
config changes for VPN support

V8:
Update for voodoo color and sharpness fix

V7:
Made some config tweaks for RFS file system for when lagfix is disabled

V6:
Updated to voodoo sound v6

V5:
Updated to support 3 pole headset calls (also 3.5 aux jack on car stereo )
Removed loading of FM radio. Thanks AdamOutler for catching that.

V4:
Updated to voodoo sound v5

V3:
enabled CONFIG_OABI_COMPAT for fugu tweaks compatability

Any chance this will see voodoo sound 5?

Yes for sure on the voodoo sound v5 and a maybe on the OC/UV.

Can't say I ever even thought about it, but I'll bump it from 5 to 10 in the next version. I assume the ROM you are running also supports it?

Just out of curiosity, how much testing was done prior to the first release?

I've been running it for about a month now personally on my dev and daily phone. Also built the new UrsaMinor kernel with the same source for TeamKomin and they have been testing.

So I guess some... but not the whole world.

perosredo said:

EDIT: And would you be able to comment on how afar apart the Armani base kernel is from say, the i9000?

Thanks.

Also, would you recommend going with JL2 over a i9000 based modem?

As for the comparison all I can give is my limited knowledge and opinion. The i9010 is almost identical hardware to the Captivate. So the base kernel code is closer to the Captivate than the i9000. An example of that would be there is no need to reorient the i9010 code for portrait like you have to in the i9000 code.

<snip>
JL2 is a 9000 modem, sorry for the confusion.

Maybe someone with more knowledge/advice will chime in as well.

looks nice, but why not voodoo sound 5?

Cause when I started it v4 was the latest. I'll take a look at v5 and see what I can do.

Version 4 of the kernel is in the 1st post now with voodoo sound v5.

Have fun.

So....any testing of the 10 point yet? I'd love to see a screen shot of all 10 of your fingers working on the screen at the same time.
