Q&A

Q: i have long charge time !
A: there is a driver to reduce charge current if battery temp goes high to prevent damage, if cpu temp goes high thermal driver will cut off freqs so it can reduce charge time, so monitor system for why temp is high specially on battery.

Q: can i turn intelli_thermal_2 off to get better performance?
A: we have 2 intelligent thermal control driver, if you turn it off the built-in driver will get online and control the temperature which is controlling temp during the boot till intelli_2 get online then you can have more control over it. i changed parameters from 80 & 90 degC to 72 & 75 degC for safer temp control (as a user requested ). so if you want get higher freq values at higher temperature you should get control of intelli_2. caution: reduce the temperature for long life.

Q: i can't get last_kmsg , there is no last_kmsg ?
A: actually there is a tunable parameters to let the kernel dump it at fails but you can use ADB and get live kmsg log at terminal by running "cat /proc/kmsg". it will show you live show
Code:
<3>[ 8624.446243 / 07-07 11:08:50.416] pre-check do_freq_control temp[47], 				limit_idx[14], 
<3>[ 8624.696399 / 07-07 11:08:50.666] pre-check do_freq_control temp[48], 				limit_idx[14], 
<3>[ 8624.946358 / 07-07 11:08:50.916] pre-check do_freq_control temp[47], 				limit_idx[14], 
<3>[ 8625.196421 / 07-07 11:08:51.166] pre-check do_freq_control temp[46], 				limit_idx[14], 
<3>[ 8625.446387 / 07-07 11:08:51.416] pre-check do_freq_control temp[46], 				limit_idx[14], 
<3>[ 8625.696374 / 07-07 11:08:51.666] pre-check do_freq_control temp[46], 				limit_idx[14],
if you want get log only for your desired parameters like temp you can limit it with "cat /proc/kmsg | grep temp"

Q: my device is always hot and max freq is decreasing to lower values?
A: depends on your config, decreasing max freq is due to thermal limitation ( protect your device from heat by decreasing max freq to produce less heat ... ).
you can find out which process using the cpu and cpu produced heat :
run "top -s cpu" in your android terminal or adb :
Code:
  PID PR CPU% S  #THR     VSS     RSS PCY UID      Name
22972  2  26% S    14 1362360K 135488K  bg u0_a23   android.process.media
 4432  0  24% S     4   9680K   2632K  fg media_rw /system/bin/sdcard
 4974  1   7% S    14 1354472K  69500K  fg system   com.android.settings
  361  2   3% S    18 191664K   6452K  fg system   /system/bin/surfaceflinger
22960  0   2% S    10 1716192K 198660K  bg u0_a38   com.android.gallery3d
23060  3   1% R     1   3068K   1288K  fg root     top
21534  0   1% S    20 1221608K  49832K  bg u0_a104  com.grarak.kerneladiutor
 3532  0   0% S   148 2023996K  93580K  fg system   system_server
 1134  0   0% D     1      0K      0K  fg root     mdss_fb0
in this case process.media is using much more that other processes , find out why it's running or end that process.

Q: i faced lag ! what can i do ?
A: depends on your config, but try ramp up thermal degC can prevent to throttle freq & cores (you will kill your device by heat )

Q: can i take my device temprature down ?
A: depends on your config, try lower down temprature degC limit to make throttle freq & core as soon as possible.
lower down max freq, you have not to kill performance at all try free up the ram from unwanted apps

Q: i have long charge time ?
A: i switched cpu_governor at charge process to have shortest ( ~ 1:20 ), monitor its rate at battery usage.( i've tested slim and alucard )

Q: what you mean by optimized build?
A: simple answer is i use GCC build flags in build process, google it.

Q: do you have any script for configuration?
A: actually i'm trying to build some script :
example: to drop cache and free up ram in scheduled time using: echo 2 > /proc/sys/vm/drop_caches
and some cool script from dorimanx
implementing stweak can fix all of these stuff

Q: why there is a build for slim governor and one for elementalx?
A: they have almost similar code, they can't live toghether or i can't make them.i'm working on it.

Q: do you have plan to build with separate toolchain, like uber-7,5 or linaro ?
A: it depends on users feedback, let's experience them, who cares

Q: do you support other variants like D852 and ... ?
A: as far as i can

Q: why kernel options not tuned?
A: i've planing to implement stweak to have control over sysfs

Q: what is your kernel config?
A: i satisfied if i have 0% or 1% during the night

Code:
   # My simple profile
   cpu alucard
   hotplug alucard
   gpu powersave
   i/o noop 1024
   screen
      	        232 237 256, saturation 75 (franco config)
   entropy
		read 512, write 256
   fsync off
   thermal
		core control off
		freq throttle 75, core throttle 72
		temp,core hysterecis 10

   # my smoothness profile
   cpu slim/elementalx
		down_differential 10
		input_enent_timeout 800
		sampling_down_factor 2
		ui/sampling_rate 15000
   hotplug alucard
		sample_rate 35%
   gpu msm-adreno
	   	simple algorithm laziness 3, ramp threshold 7
   screen same
   i/o fiops 1024
   entropy same
   fsync same
note: for better performance set same sample rate at cpu and hotplug

maximum compressor streams can change from 1~4 cpu
## enabling zram can drain battery faster, google zcache,zram,frontswap
## to enable 512 MiB zram copy these commands to your init.d script or run in terminal:
Code:
	swapoff /dev/block/zram0;
	echo "1" > /sys/block/zram0/reset;
	echo "lz4" > /sys/block/zram0/comp_algorithm;
	echo "2" > /sys/block/zram0/max_comp_streams;
	echo "512MB" > /sys/block/zram0/disksize;

	swapon /dev/block/zram0;
* Process reclaim implemented (i don't think it's working ...)
* EXT4 filesys updated
* Frandom implemented (10-50 times faster than what you get from Linux urandom)
* Disabled crc check
* memutils, memcpy, memmove optimization

## filename resolution
SLIM is for slim cpu_governor
ELEX is for elementalx cpu_governor
U7 is for UBERTC-7 toolchain
U5 is for UBERTC-5.3.x toolchain
L5 is for Linaro-5.3.x toolchain
OPT is for optimized with gcc build flags
STK is for no-optimization

you know i'd failed for fF400 with LP, i will try again, if you know anyone who build stock MM for F400 please introduce him/her to me,tnx
i should get sources,step by step during the time
