Battery usage is a little better. Kernel is running smooth !

Thanks Faux !

Always comin out with the new hotness. New kernel plus new faux clock... man last night was a good night only thing missing was a new SelfKANG... anyways ill stop rambling.

Keep up the awesome devin amd thanks for bringing the latest and greatest technology to us

CyanogenMod 7 Open Beta build-02: Introducing advanced SMP optimization and battery saving techniques!

Amazing but true, CM7 actually suffers from TOO much performance, thus killing battery... I have optimize my kernel to address this issue.

My recommended Setting for CM7:

Ondemand Governor Default
Run @ 1.026 GHz
Set GPU I/O fraction to 50

You will NOT suffer any performance loss and the battery life will be excellent.... Enjoy have fun!

BTW, open beta is J-RCU only @ 1.56 GHz, DON'T BOTHER TO ASK for another version!

Version 0.2.3 (Beta Coming Soon, CM7 Alpha2+)

<01>
Added XZ Compression support to 2.6.35 kernel
Added XZ Compression support for kernel image
Added XZ Compression RAMDisk support (boot time)
Used the git implementation of SHA-1 to reduce boot time by 11%
Updated qdsp6v2 to block write until buffer is full
Updated trivial bug fix for SMP macro
Added newly optimized CRC32 Improves EVERYTHING that uses it including TCP/IP, File Systems etc...
Added newly optimized CRC32c improves EXT4 metadata performance and anything else which uses CRC32c
Patched msm_serial_hs_lite (better battery life)
Patched qdsp6v2 to fix unexpected power consumption (better battery life)
Patched mdp4_overlay to flush RGB pipe when solid fill mode is used (better battery life)
Patched clock-8x60 to add a lower gsbi_uart_clk entry to save power (better battery life)
Lowered Camera Flash limit from 30% to 10%
Tweaked conservative governor for better interactive performance (made default)
Lowered CPU Minimum Voltage (better battery life)
Gate smi_2x_axi_clk off when smi_clk is disabled (better battery life)
Fixed performance level computation for VCD (better performance)
Added local control of vpe_axi_clk and rot_axi_clk (better battery life)
Removed unnecessary checks from DMA engine (more efficient DMA Engine == performance)
ARM Patch: Use CTR for the I-cache line size on ARMv7 (better performance)
Enabled inline locks for ARM (performance)
CPU workqueue optimization (limit some workqueues to single thread)
patched qdsp6v2 to Set tx and rx flags based on current device
patched display to avoid staging up two pipes at same mixer_stage
<02>
Added GPU slumber (whenever screen is off, GPU is set to sleep)
Added idle wait support for SMP
Fixed AXI clock bug in GPU
Fixed L2 Cache Synchro bug
OnDemand made default

Love the open beta tests nice to have a lil experimenting on the cm side of things sense is cool but gets blah after a while. Conservitive is a lil laggy for me so im using on demand. Last beta was nice just flashed #2 and will report my experience with it later today but im likin it better so far

I love you daddy
Flashing now, will report back.

What command would I need to use to set GPU I/O fraction to 50? I prefer running scripts rather than the faux clock app.

Here you go!

echo "50" > /sys/devices/platform/kgsl/msm_kgsl/kgsl-3d0/io_fraction

have fun!

hey faux123, what is the new lowest allowable voltage value in your new kernel? thank you. would be great if you could lower it to 725mV if possible

800mv. That's the lowest for my kernels. I will experiment with lower voltages.. later on...

flashing, will report tomorrow
