Hi everyone, this kernel aims to be fast and stable and have good battery life. It should be what the infuse comes with.

Latest features:
- Compiled using codesourcery 2009 (will be updated to 2010 which brings optimizations and speed)

This kernel has/is:
- Works on all voodoo enabled roms
- Currently not included neldar's BackLightNotification 2.3
- Includes supercurio's Voodoo Sound v9
- Includes jhash3 function for performance and reliability
- Adjusted kernel HZ value to improve smoothness
- Properly working TinyRCU for better speed and efficiency
- Patched lowmemorykiller for compatibility with TinyRCU
- Modified Initramfs for performance
- BFQ is the default i/o scheduler (other i/o schedulers will be tested as time goes by)

If your keeping up with h8rift's rom Refuse(1.4 and up) then your using my kernel :)

Everyone else, the zip is for flashing via cwm and the tar is to flash via odin.

Note: I do own a infuse as of 06/17 but if you'd like to donate because of
my work, feel free to do so and thanks :)


SOURCE is UPDATED:
https://github.com/razor950/Defuse-Kernel

Changelog
V1.0
- Implemented tinyrcu and lowmemkiller
- Implemented neldar's BackLightNotification 2.3
- Kernel HZ is at 500
V1.1
- fixed video memory bug (this fixed ffc / video decoding)
V1.2
- implemented supercurio's voodoo sound
- added jhash3 function for speed and better reliability
v1.3

v1.4
- added ext4 patchset (LinuxBozo)
- implemented BFQ I/O scheduler and set it as default (LinuxBozo)
- minor compiler flags for optimization (still need to add to this)
- modified initramfs tweaked for performance (LinuxBozo)
- BLN is off for now due to it being too random with bugs (no eta when it'll be back)

Note: I do not have a infuse4g and I probably won't be getting one, I am a
T-mobile user but I will work on CM7 if I grab some donations :)
If you'd like to donate, just hit the donate to me button on the side.

Do you need enough donations to buy an Infuse before you start working on CM7, or are you gonna use some witchcraft to port it over without even having one if people donate some money to you?

If you need an Infuse and everyone starts to donate, I'd jump in to and donate some money. Or if you're able to do it with just donations and no phone, I may donate as well.

I do not ask for money to keep development going....

Donations would go straight to buying a infuse but I might be willing to just go out giving a certain amount of donations and I am not sure because I've never really asked to donate...


just to double check, is BLN working?

I am going to bed, i know h8rift tested it today and bln was working, I'll double check tomorrow...

it won't be a completely noticeable difference yet until more changes but BLN is nice (I'll check why its not working)

Only thing I can suggest is try latest refuse 1.4 rom and let me know if BLN works then.

Can't tell if I got it but benchmark is stuck at video decoding and won't move? Can someone tell me how to see if it flashed ok?

Ah alright.

And it looks like BLN is working for me! I just installed BLN and got a text, and the backlights lit up! Thanks a lot! You are the man!

I also got stuck at Video Decoding in the benchmark. Outside of that everything seems to be working fine so far.

Edit: Nevermind, it looks like the front facing camera is broken again. I was on the newest Infused rom and it worked there, but after flashing this kernel it doesn't work anymore. My phone froze after I tried taking a picture.

    I know there is a bln bug, if its the kernel or the bln software it is not known yet, I am not mad at getting bug comments but spammed about the same bug which I know is there becomes a bit too much, so please relax bln doesn't kill battery at all even if it were on 24/7.....

    at most it is just a annoyance and I am looking at it.

    here is a teaser of whats coming in a few :)

    hoofadoo took that picture and his one of the testers

    Testers have reported no issues and voodoo sound works fine...

    if the rom is a voodoo rom then yes, you can flash my kernel but if it isn't then you can not.

    I'm not trying to be rude, but this bug is definitely happening. I downloaded and flashed the kernel multiple times and still have the same issues. I'm only reporting it for the benefit of the developer. If bln is included in a kernel, it should work properly. Saying things like, "who uses bln anyways ", and "just be glad you have Voodoo" is not helping development. The problem has been reported by a few people in this thread and we're all just trying to help the dev out. He doesn't have the phone, so we're doing the testing, and as an experienced captivate user, I can respectfully say, bln is not working properly. The touchkeys time out after about five seconds or so, and shouldn't come on when touched while the screen is off. Once again, I'm not trying to be rude, I'm just saying what I've experienced with the kernel.
