@mautz: Let me tell you first, that you make me feel like a little boy, full of pleasure, testing new stuff almost every evening. Big Kudos to you!


So I wanted to share my current test settings with you, using v6 of the mautz kernel.

I recommend 2.0.4.* as sailfish version. In my opinion it is more stable than the proposed 2.0.1.11 at the first page of this thread. I upgraded my version with OTA to 2.0.4.14, but there is a new '2.0.4.13' image available here... http://images.devaamo.fi/sfe/hammerhead/beta5/

I had some very rare freezes/reboots with my old voltage table, so I went +5mV for the whole range. I might do some fine-tuning later. The device is rock stable now.

I use Alucard as hot-plug governor with default settings. I think I love that one. With the new v6 kernel I set [noop] as I/O scheduler. 'They' say, [noop] is good for battery life. Other option I might try is [fiops].

I did not touch the dimmer settings, neither 'doubletap2wake' or 'fastcharge'. 'Dt2w' might drain battery, and I see no need for 'fastcharge', using a QI charger.


Code:
# Max Frequency
/bin/echo "1728000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

# Alucard
echo "1" > /sys/kernel/alucard_hotplug/hotplug_enable

# voltage table (undervolt)
/bin/echo "680 680 730 740 760 770 780 800 810 855 870 900 950 1010" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

# simple gpu
/bin/echo "320000000" > /sys/class/kgsl/kgsl-3d0/max_gpuclk
/bin/echo "4" > /sys/module/msm_kgsl_core/parameters/simple_laziness
/bin/echo "7000" > /sys/module/msm_kgsl_core/parameters/simple_ramp_threshold
/bin/echo "simple" > /sys/class/kgsl/kgsl-3d0/pwrscale/trustzone/governor
/bin/echo "150000000" > /sys/devices/fdb00000.qcom,kgsl-3d0/kgsl/kgsl-3d0/min_pwrlevel

# set governor
/bin/echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

# set I/O scheduler
/bin/echo "noop" > /sys/block/mmcblk0/queue/scheduler
