[Nexus 7 Original Development] clemsyn:
MOD NOTE: IT APPEARS THIS KERNEL IS FOR 4.1.x ONLY. Flashing on 4.2 will result in bootloop. also, this kernel is unsupported by the OP, so thread is currently CLOSED

First and foremost, I would like to thank _motley for his kernel since this is based on his kernel. I chose his kernel because I have worked with him and IMO is the best kernel out there at the moment :). Second, I would like to thank pinoyto and secret for testing the kernels. Also thanks to Koush, Blades, faux123, pershoot, chatch15117, all the Gtab, Asus Transformer and Motorola Atrix users, and other devs that I may have missed. BIG THANKS to my beloved wife for watching the kids while I do this.

I call this kernel elite since the timings are pretty aggressive and voltage are decreased on the low side and increased on the high side. This kernel might not work on your device because of these so be sure that you have a backup and and that you are familiar on restoring your device.

The following are the difference with motley's kernel

1. JRCU is implemented

2. Lowest backlight setting set to 5 (save battery and better reading at night, if you have screen flicker issue it will be more noticable because of this so I suggest covering the ground pin of wifi)

3. Core voltage increased from 1200 to 1250mv on the high side to hit 1.7 frequency and 600 GPU but decreased from 950 to 900mv on the low side.

4. Increased CPU voltage to 1240mv for 1.7 frequency but allows decreased 750mv in low side

5. Increased GPU clock to 600 and pixclock increased (please let me know if you have problems on screen due to pixclock increase but so far no issues on testers)

6. Built using gcc 4.5.2 ( I know, I'm an oldie)

7. DVFS core table completely changed to allow max clock of host1x and pll_c and hit most max frequencies.

8. Enable Thermal_Sys to throttle at 68 (BTW, if you are using system tuner, the reading is +10 as per secret)

Added 484 GPU and 520 GPU. LMK how it goes.

UPDATED 09/23/2012

Releasing another 1.8ghzCPU and 650mhz GPU

Here are the differences with the last 650gpu

1. Used Linaro compiler

2. Increased 3d/2d bus, pll_c, and host1x for higher scores

3. Removed the pixclock overclock, This is running on default pixclock by Asus. This will limit the fps to 60 fps max, so old benchmarks will not score over 100 fps but will only max at 60. I suggest newer benchmarks like GL2.5 or Benchmark 2.0 ES Taiji...

4. EMC voltage decreased to 1.100 mv (Not sure if your device can handle this but pinoyto's device was fine with it)

*** SPECIAL RECOGNITION goes to PINOYTO for the first donation of this project. THANKS for rewarding my hard work!! ***

Thanks to masterg0g0 for 2nd donation ;)

Also thanks to all the testers of the 700mhz GPU.

This latest kernel comes with the 1.8ghz CPU and 700 GPU with 3 types of pixclocks.

First off is the max pixclock. This has the highest pixclock of all the kernels and will limit your fps to over 100 fps. The downside is the pink screen issue.

Second is the mid pixclock overclock. If you have a pink issue on the first one, try this. This will limit your fps to about 90 fps. The downside is you might still have a pink screen

Third is the NO pixclock overclock. This for sure will have no pink issue but will limit your fps to about 65 fps.

https://rapidshare.com/files/258377771/1.8ghz700gpuNOPIXOC.zip

Here are the changes made from this latest kernels

1. GPU increased to 700 gpu, vcore and vrail voltages increased

2. pll_c, host1x increased to accomodate the increase in GPU speed

3. Compiled using Linaro toolchain.

WARNING:

The timings in this kernel are very aggressive, voltages although within Nvidia limits are high. Please make sure you backup and be very familiar in recovering your device.
