Hello,
Is there any reason why the scaling min freq is not equal to the cpuinfo_min_freq?
By default the scaling min freq is set to 245760
However the cpu can go to 122880
I have manual set this and the phone seems to run fine, changing freq on demand as need and slowing back as it should
I tried editing the /init.qcom.post_boot.sh so it does it every time on boot up but it just overwrote the file with the default

I use overclock widget and it do the job (need root)
True, overclock widget sets it perfectly, lets hope this saves more battery
To check cpu running speed use system panel ..
I think that there's a reason cause they set the kernel to that frequency. Probably 122mhz is too low for gsm csmda radio activity or probably cause after some tests they saw that there was no difference in stand by between the two power consumption levels.
I got no problem when on idel setting the max cpu freq to the lowest speed possible
If there were not problems about it they would set it to 122Mhz. Maybe they solved some lags, who know what. But if it's at 245Mhz a reason exists.
Anyway.... I don't know too, I think only Sony Ericsson developers could tell something about this choice.
Probably so their crappy interface and built in demo apps can work
Have had no issues running this at boot time ( via root )
---------------------- snip ---------------
#!/system/bin/sh
echo 122880 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

i save this as "slow.sh"
then run
#sh slow.sh
now idle uses 122.88 mhz and saves alot of battery!

1. you need root
2. create file "slow.sh" with this entry ( can use notepad or whatever )
#!/system/bin/sh
echo 122880 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
save anywhere eg: /sddcard/slow.sh
3. open a terminal *ConnectBot works fine
4.
$su
#sh /sdcard/slow.sh
5. exit your terminal
note: you need to do this everytime you reboot your phone
I use Android System Info ( System / CPU tab ) to check the cpu usage

This modules are for people with stock kernels because they don't have 'smartass' or ondemandX' governors.
EASY ENGLISH:
Differences between this modules and build in stock kernels:
- allows to set max CPU freq when screen is off (to save battery),
- allows to set starting CPU freq when phone awakes (to speed up awake process),
- allows set/change almost all aspects of governor (to suite needs),
- should be a bit more responsive when parameters are well chosen for smartassv2 governor.
Each governor has some predefinied values - more info in "Available settings".
If governors works or not on other version then 4.0.2.A.0.42 let me know.
Start:
The goal was bring 'smartassv2' and 'ondemandX' governor to work with stock kernel on Neo V.
Most information is in my thread on 'XPERIA X8 Android Development': [Module] | X8 | X10 mini/pro | AX8_SMARTASS v002 | 'smartass' governor | [2011-07-19]
To remind:
SmartassV2 (informal description and comparison with the first smartass)
SmartassV2 is a governor (controls the frequency of the CPU at each give moment) which like the first smartass is generally based on the implementation of interactive with some major changes and the addition of a built in sleep profile (behaves a bit differently when screen is off vs. on).
The smartassV2 improves the very naive scheme which the first smartass had: The first smartass (with the values I set for the hero), would cap the max frequency at 352Mhz for sleep and when screen is on, would do the opposite and keep the frequency at 518Mhz or above. For sleep this was very effective but a bit crude and unclean, and there could be some cases where you would need processing power even when screen is off (something is updating and music is playing and etc.). For screen on, smartass1 was too quick to jump to the max available frequency and again would never go below the 518Mhz, so in a nutshell its was using "too high" frequencies.
SmartassV2, introduce (internally) an "ideal" frequency which is the frequency we are "aiming" for, in some sense. The way I see it is that the "ideal" frequency is a hint to the governor what is a good balance between performance and battery life. Now when screen is on, I set (on the hero) the ideal frequency to 518Mhz which will ensure nice responsiveness but limit unnecessary use of higher frequencies when they are not needed. When screen is off, I set the ideal frequency to 352Mhz (0 will disable the screen state tracking all together). From my testing this will "convince" the governor to spend most of the its time during sleep at the lowest available frequencies. Note, that both during sleep and when awake the entire frequency range (as defined by the "user" - i.e. selected with SetCPU) is used by smartassV2. For example, when the CPU is loaded heavily, the highest available frequency will be used regardless if screen is on or off.

ondemandX - ondemand governor code from latest linux (3.0 at the moment) source *plus* the suspend/wake logic described above. No further optimization is done.
Click to expand...
Click to collapse
Info:
- information about governors is here,
- more information about 'smartass' governor is here or here,
- how different governors work is explained here: [Q] SetCPU governors (explained).
Prerequisites:
- Neo V (if works on Neo - let me know),
- root,
- ondemandX should work on any version,
- smartass was compiled against 4.0.2.A.0.42 version, how run on other version will be explained in manuall installation section,
- desire to replace SetCPU - when used only for 'ScreenOff' profile.
Manual installation:
Unzip file
Run copy.cmd file - this should copy modules to /system/lib/modules
run adb shell or terminal - whatever you like and execute su
Code:
su
If you have 4.0.2.A.0.42 version proceed to step 6
For smartass governor you need to know address for 'kallsyms_lookup_name'
run following command:
Code:
cat /proc/kallsyms | grep kallsyms_lookup_name
result should be as follows:
Code:
80101aec T module_kallsyms_lookup_name
[SIZE="3"][B]801056f0[/B][/SIZE] T kallsyms_lookup_name
Bolded value (801056f0) is address which we need.
Optional step: lower min CPU freq:
Code:
echo 122880 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
Insert ondemandX module:
Code:
insmod /system/lib/modules/aneov_ondemandx.ko
in dmesg command should be line:
Code:
<6>[ 431.711517] aneov_ondemandX: module v001 for device Xperia Neo V loaded
Insert smartassV2 module:
for version 4.0.2.A.0.42 just run command:
Code:
insmod /system/lib/modules/aneov_smartass2.ko
in dmesg command should be line:
Code:
<6>[ 420.308380] aneov_smartass2: module v001 for device Xperia Neo V loaded
for other use 'address' and use following command:
Code:
insmod /system/lib/modules/aneov_smartass2.ko lookup_address=0x[B][COLOR="Red"]801056f0[/COLOR][/B]
in dmesg command should be line:
Code:
<6>[ 420.308380] aneov_smartass2: module v001 for device Xperia Neo V loaded
Now you can enable desired governor. Execute:
Code:
echo "smartassV2" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
for smartassV2 or
Code:
echo "ondemandX" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
for ondemandX governor.
Lower min cpu freq a bit:
Code:
echo 122880 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
Until you're sure that it works with your hardware, don't install it to hw_config.sh.
Available settings:
Will be added later
v001:
- just initial version fixed to work with Neo V.

Thank you!
On .62 firmware, I didn't have to specify lookup_address, since it didn't recognise that option, but it seems to work.
Also a good full article about governors:
http://forum.xda-developers.com/showpost.php?p=19846276&postcount=1
is there any chance to get this as a zip for cwm?
edit:yay! just put it manually into system/lib/modules and changed permissions and it works!

Also please see these commits for some changes to smartass2 (more stable) and working lulzactive
thread dead for more than 2 months...
Zed's dead. but no matter
OK- so I'm planning on installing the module on a different device. with the assumption that the smartassv2.ko drivers are all the same, i figure that only the specifics differ.
e.g. no /sys/lib folder exists in my system, though a /sys/modules folder does.
So, the plan is: i edit the script to point towards the valid directories; place the files in those noted directories (eg create a /sys/lib/modules folder); edit the "scanning_available_governors" to mention those governors; kick back and enjoy.
two things concern me. First, I checked the symsearch.ko file found references to the kallsyms, as well as to the general public license and ARMv7, but haven't found much info online as to what the driver does. since it mentions architecture that may or may not adhere to my device (samsung galaxy player 5),should I go ahead?
Second, OP mentioned:
"result should be as follows:
Code:
80101aec T module_kallsyms_lookup_name
801056f0 T kallsyms_lookup_name
Bolded value (801056f0) is address which we need."
the instructions following that line doesn't mention the kallsyms_lookup_name addy again. so what is the addy good for?
thanks!
Wow IT REALLY WORKED.
i have smartass V2 on My locked bootloader .
Thank you.
(Yes i know i am a gravedigger but more people have to see this.)
Just everyday i find one more reason for not to unlock my BL.
I have the best governor
Best tweaks.
OC is useless (it consumes battery and Destroyes the phone).
WHY THE HECK WOULD I WANT A CUSTOM ROM.
EDIT: Erm guys how do i install it with hw_config.sh
It may be a silly question, but after reading descriptions to both the badass and the smartass v2 governors, but I'm still not quite sure which one will provide better battery life overall.
SmartassV2 is the answer ;P
not working on miui 2.7.13 based on 4.0.4

It seems faster than CFQ to me.
It was developed mainly for SSD drives!

It is for .28 kernel
FOR 2.6.39 Kernel only! = e.g stock .21 , stock .28 , ANDROWOOK kernel and all roms/kernels based on Asus kernel source!!
WORKS with Asus TF300 too!

at first the scheduler is visible in setcpu, but after reboot it disappears, gonna test now in a single session without reboot, starting with some sqlite tests and playstore installations.

Typo corrected
Of course because module is not loaded after reboot.
Thats why I write to author of atp because his app can save governor after boot.
And i dont want edit init.rc because typo can kill my prime without unlocked bootloader.
Sio is mainly for user end ooint it's not for benchmarks...
first test results; no improvement in raw speed as all ready stated above.
did some updates on play store and experiencing lockups\anr as before.
currently using browser2ram but will disable it to test how browsing goes on content-rich websites!

Great idea though. This combines both concepts of noop and deadline. It does what noop does with basic in and out and organizes database accesses without any prioritization.

It is compiled against stock 2.6.39 kernel, if it runs on another onethan ok but you can have stability issues.
2.6.39 compared to 3.0 has different structure.
But ok if it run, than ok
This is great! Tried it on my rooted locked prime, the difference is huge when I tried to open a pdf with lots of images. Will test some more with other apps.
Let me know your opinion after testing!
It's my daily IO governor just right now.

Thanks.. but to be more efficient, I would like to have them separated.
1. User install my module pack. (extra_kernel_modules_*.zip)
2. User install init.d loader. (init.d_n_governor_installer.zip

I tried to use your flashable zip. It doesn't work, but I found that after I chmod 777 the 90module in the init.d folder it works flawlessly. So I think you need to add that set permissions to your script.

Fix....
I don't think the ntfs.ko is working right. I just formatted an sd card with ntfs to test it out after loading the module and it pulls it as a blank sdcard.
Will this work on an XT910? Is the kernel source any different from the 67.42.17.XT910S.SKT.en.KR?

don't blame the ntfs.ko, it's MotoBlur problem.(vold limitation)
You have to mount your NTFS partition manually.

Yeah, I realized that after I commented and was playing around some more. Motoblur is the one throwing the blank sd card issue, not the system itself.
So I think it's time to go back to playing. I'm loving the new governor.
does anyone have an init.d script they could throw up to run one of these on boot?

Q: How to load a cpufreq governor
I flashed the zips and have not been able to automatically pick the governor while in setcpu.
I loaded up terminal and did the commands you posted but those didnt work unless i substituted /system/lib for /system/bin. Doing that I can now select interactivex. I'd love for the init.d scripts to work so I dont have to fumble around with this every boot. My rom does have init.d support.
Is there a reason for the difference on my phone? I have a razr maxx and running the newest kernel from build 214 and on Arctic rom.
Thanks.

Thank you for this. I loaded both zips & init.d works perfectly for me on an OG Razr running the stock 211 rom/214 kernel combo. Everything is available to select & it all runs at boot. System Tuner Pro is what I use to select the governor/scheduler settings.

Thanks for the modules! They work perfectly. I was wondering if its possible for you to write a script/module that would support editing vsel values for undervolting the cpu. Would be really helpful in extending battery life.

export t3 variant to debugfs by faux123 (adb shell cat /sys/kernel/debug/t3_variant)
lowered panel min brightness to 8
ZRAM
enabled NFSv3&4
Check the compare links for the rest
Where is tha Changelog???
There will be no more changelogs.
Instead the download pages were outfitted with compare links to github for each download.
How to install?
Flash through recovery. #done.

What is tegra_mpdecision?
100% kernel based multi core decision! (should cpu1/2/3 be online or not, do we need the low-power/ninja core now?)
This replaces the stock nvidia hotplug solution.
Check /sys/kernel/tegra_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (20000)
delay = time between checks (130)
pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)
scroff_single_core = Force low-power mode if screen is off (1)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
min_cpus = min cpus to be online, cannot be < 1. Default: 1
max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4
idle_freq = a value against that will be checked if a core +/- is requested. (475000)
lpcpu_up_hsyteresis = minimum number of requests that have to be send in order to switch to low-power mode (4)
lpcpu_down_hsyteresis = minimum number of requests that have to be send in order to switch to g-mode (quadcore-mode). Overridden by a requested freq that is higher than the max supported lp-mode frequency. (2)
If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.
If any other cpu is above that value and a core down of that cpu is requested, nothing will happen. (otherwise it would now put down that cpu even though it is still working, which isn't what we want)
Hot plug thresholds (aka now it gets 'complicated')
This small formula calculates which value will be used: (number_of_cpus_online - 1) * 2
The result of this formula will be the nwns_threshold where a new cpu is hotplugged.
The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.
nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged
twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)
Example:
One cpu is online.
(1 - 1) * 2 = 0 ergo:
nwns_threshold_0 = cpu1 will be hotplugged at this value
((1 - 1) * 2) + 1 = 1
nwns_threshold_1 = cpu0 will be unplugged at this value
This will regulate when we switch to lp-mode, effectively replacing the quadcore g-mode core with the ninja lp-mode core.
Two cpus are online.
(2 - 1) * 2 = 2 ergo:
nwns_threshold_2 = cpu2 will be hotplugged at this value
((2 - 1) * 2) + 1 = 3
nwns_threshold_3 = cpu1 will be unplugged at this value
etc...
(all times are in ms)
If you want to see the mpdecision magic happening:
Code:
adb shell
cat /proc/kmsg | grep 'MPDEC'
mpdecision's input event boost, aka project butter
This will boost your min cpu speed if you touch the screen or press a button and gives you full control.
In those events the min cpu freq will be risen to a predefined value (look below) on every online cpu. This boosts overall reaction times and smoothness a lot. (works similar to the qcom mpdecision binary)
Configuration files:
[email protected]:/sys/kernel/tegra_mpdecision/conf # ls
boost_enabled
boost_freqs
boost_time
All of them work like the usual sysfs files, except one special case:
boost_freqs will list all frequencies from cpu 0 to cpu x. Cpu 3 and any following cpu will share one frequency.
To change those frequencies echo the cpu number + the frequency in khz. To change the boost freq of cpu3 (and 4,5,6,7,8, etc) the echo would look as follows:
Code:
echo "3 1026000" > /sys/kernel/tegra_mpdecision/conf/boost_freqs
for cpu0:
Code:
echo "0 1026000" > /sys/kernel/tegra_mpdecision/conf/boost_freqs
Defaults:
Code:
cat /sys/kernel/tegra_mpdecision/conf/boost_freqs
910000
910000
760000
620000
Recommended governor?
Ondemand.Why do I have no WLAN?
This kernel is too big for our boot.img with WLAN included into the kernel, so it is built as a module. That means it needs to be inserted into the kernel upon boot up, which needs to be automated for maximum comfort = userinit (init.d) support.
The zip adds init.d support to your ramdisk, if that fails for some reason the wlan module cannot be inserted.
if
Code:
adb shell lsmod
doesn't show this:
Code:
tun 14060 0 - Live 0x00000000
cifs 239646 0 - Live 0x00000000
bcmdhd 433083 0 - Live 0x00000000
Then init.d support is probably missing.
You can test it by going to /system/etc/init.d/ and executing 00wlan.
Code:
adb shell
su
. /system/etc/init.d/00wlan
Wait a few seconds and try to enable wifi and repeat the above lsmod command (should now show bcmdhd as live, you can execute 01cifs and 02tun too).
If WLAN now works, init.d support is missing.
You need to have busybox installed in order to be able to get init.d support going, this shouldn't be a problem for most people, since it is usually installed when rooting your phone anyway (and who does unlock but not root their phone? :/)
It does not matter if busybox is installed in /system/bin or /system/xbin, my script will detect the location upon flashing and patch the ramdisk accordingly.
If no busybox is found, the script will add init.d support to your ramdisk with the default location: /system/xbin/busybox. All you need to do is install busybox there and reboot your phone.

All AOSP roms work with Bricked
* Hello World *
What tweaks did you make to on-demand, if you don't mind me asking? The only thing I've noticed is that frequency switching seems to happen faster & more often.
Feel like flashing something tonight!

I tried flashing this a few times and it fails with each try.

I mostly adapted it to work with the lpcore while the screen is on and also with special power saving setting while the screen is off.
The 2 phase frequency was changed to accomplish that.
It also applies a powersave bias while screen is off.
Additionally I changed the settings to allow faster scaling with less load. (70% > freq incr)
Source is currently being uploaded, but since I kept the history intact it is taking ages. You can look it up there in more detail once the source is up

I guess because your recovery does not identify your device as 'grouper'.

Nothing wrong with the zipfile, maybe corrupted download? did you do md5 hash check before flash?
It's either your custom recovery or a corrupted download, period.
ps. Happy Flashing.

As long as it is AOSP you should be fine.
But just try it and report back, then we are all a bit more enlightened
