RAMDISK.TAR a few issue's to resolve. - Sony Ericsson XPERIA X10 Mini

I have noticed that developers here like to shove VM and Cpu setting into the init.delta.sh file.
The problem with this is compatibility.. for example using the smart ass govender with these settings...
echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 90 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
echo 30 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/down_differential
echo 500000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
echo 122880 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 614400 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Will most definitely cause issue's where the frequency will get stuck.
Why not make it possible to rather edit these value's externally.
as these can also be called from hw_config.sh there by causing less problems when users try to make 3'rd party changes.

I'd like to tally your CPU freqs + volt settings

I've always found undervolting does wonders for phone battery life.
I'd like to record everyone's settings at
192mhz
384
540
702
810
918
1025
1188
If you could post your lowest stable voltages for some or all of these frequencies we should be able to figure out a recommended underclock profile.
I like your idea!

im using Kernel tuner also
any settings you want me to try ?
I'll wait for a consensus before suggesting anything but you lower to mid freqs seem a bit high I think.

I experienced an infinite boot yesterday, i had to put a new rom+kernel , may the undervolting have caused this? i just put everything back and im going to try the same settings and see what happens, could you point out which freqs i could lower the voltage on?

Takes lots of trial and error.
Use CPU Tweaks to adjust. Set it to re apply on boot completed. Not with init.d script. It won't reapply next boot if it detected a lockup last boot. I was thinking the 700-972 range was a bit high.

I think 810-972 could be 50mV lower across the board.

Still not the lowest possible voltages, but completely stable....
Edit : reworked voltages, still stable
Might be possible to lower voltage for a few single freq, but the next -12,5 @ all makes it crashing ( on my phone)
Edit 2: Had a few reboots, could be too low (@ ~1000 MHz ?) , +12,5 lets See how it works

I tried these settings and it was extremely unstable :/ coulnt open a single app... im on the pacman rom with buttered toast 14.1...
i get a reboot every time i apply the settings. could it be that the kernel doesnt support undervolting? any other settings ?

Due to how chips work what with error correction and all it's probably best to go +25mV or +37mV from the crash frequency. If you notice lags during rendering of the sense fly in after unlock, that's the error correction engaging, back off the undervolt a bit. The problem is there are easy too many frequencies. We need someone to produce a kernel build with 7 slots not the stock 20 or however many there are.

How to get better performance in games (root required)

I just wanted to share a few tricks i learned to get graphics-intensive games to run much more smoothly. These commands should be run in android terminal emulator as root, in adb shell as root, or ran as a script with any script-running app with root privileges
All of the following is only temporary and will be reset to normal after a reboot
Code:
stop mpdecision
stops the hotplugging binary used to turn on/off extra cpus we want this gone because we want to specify which cpus are online ourselves
Code:
echo 1 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu2/online
echo 1 > /sys/devices/system/cpu/cpu3/online
turns on the other cpu cores (you probably don't need all 3 extra cores on, just turning cpu1 online makes a big difference)
Code:
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
sets all online cpus to maximum frequency
Code:
echo performance > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/trustzone/governor
sets the gpu to stay at maximum frequency
as a script:
Code:
#!/system/bin/sh
stop mpdecision
echo 1 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu2/online
echo 1 > /sys/devices/system/cpu/cpu3/online
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo performance > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/trustzone/governor
would this help improve general smoothness across the ui and other apps? Does it reduce the choppiness in the maps app????
It would, but i'm not sure how long the battery would last.
Faux kernel with Faux Clock you can do all this! It is great!
Jeepers. Seems the device gets hot enough without doing this, but what makes the user happy.

havent noticed mine get that hot at all?
Perhaps subjective to the user. Playing 3d games gets the device hot and OC ing will get it hotter. If the user does not mind, that is what matters.
may add this to the roms/ guides / etc list

You might also want a script for when you're done with gaming. Probably something like:
Code:
#!/system/bin/sh
start mpdecision
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/pwrscale/trustzone/governor
This way once you're done with gaming/whatever, the phone can go back to scaling down CPU speeds and hotplugging cores to save battery. It's not very useful for an idle phone to have all 4 cores active and running at full speed.
What if I just reboot the phone, would that stop the script(s)? Anyone try the S4 with PSP emulator (PPSSPP)?

Rebooting would restart mpdecision, and therefore let your hotplugging go back to working order. I'm not certain it would reset your governor, though. So your phone may still be running at full speed 24/7, even after a reboot.

I don't think start mpdecision will do what you're intending but according to cat "/proc/`pgrep mpdecision`/cmdline" it was started by "mpdecision --nosleep --avg_comp"

Keeping oom_adj value of specific apps low permantly

Hi there,
My Messaging APP can hardly stay running in background, and this cause me receive those important messages late. After digging in some information, I found that changing the three oom values of the process can make LMK see this process as high priority and won't kill it easily. By the way, I also changed niceness. However, it seems that Android system will change those oom values itself after a particular duration, so my tweak can only take effect in a short time. Is there any way to lock oom values or reach the same result?
My script of changing oom values and niceness:
Code:
#!/system/bin/sh
X=$(pidof jp.naver.line.android)
echo "-17" > /proc/$X/oom_adj
echo "0" > /proc/$X/oom_score
echo "-1000" > /proc/$X/oom_score_adj
renice -n -20 $X

[MAGISK][MOD]--Pixel4a-CpuTweak--V2

Pixel4a-CpuTweak--V2​
Short story : I do from time to time some monitoring on my phones(Using Francokernel app). Watching cpu freq, battery amp, etc. Since Android12 on my Pixel4a i noticed the cpu was almost always high for no serious reason compared to Android11. So i made a little script that use magisk to run as root and on boot to change some kernel parameters to make cpu way more batery friendly. It just let the little cores goes as low as they can and use the big cores for heavy task.
If you noticed a bad Screen On Time since Android12 then this module is for you.
This magisk module will make your cpu consume less power.
-Little cores can now go down to their lowest frequency
-Big cores are used for heavy task

I cannot speak for battery life but my phone feels significantly less responsive after installing the mod. Otherwise great idea, just doesn't work for my workflow.

Thanks for the feedback. I've updated the module if you wanna try again. There was some typo that could make the phone less responsive. Now it will work as intended.

Short story : I do from time to time some monitoring on my phones(Using Francokernel app). Watching cpu freq, battery amp, etc. Since Android12 on my Pixel4a i noticed the cpu was almost always high for no serious reason compared to Android11. So i made a little script that use magisk to run as root and on boot to change some kernel parameters to make cpu way more batery friendly. It just let the little cores goes as low as they can and use the big cores for heavy task.[/SIZE]

COuld it be thyat by checking your phones current CPU useage, you are actually using ypour phone, and so the governor is ramping up your CPU clock to ensure the phone is reacting or ready to react? Have you compared your changes to switching to the conservative governor? (I am guessing this gov is available on the phone).

There's no conservative governor in stock kernel. Schedutil is good and many little component rely on it (at least on stock rom)
Yes checking your cpu usage use cpu but you see how much and its so little that it doesn't ramp up cpu.
Android like Linux have the "top" terminal cmd which display the current process in use. More or less like task manager windows have.

You are right, there is no "Conservative" gov. its not called "Conservative" but there is one called "Powersave"; which is the conservative gov, just named differently to what has been on my previous devices.
I took a moment to have a play, and set all the CPU's to the powersave gov, and found (surprisingly) if I set the smaller govs to powersave, then I notice big lags. Especially in the "tripple-tap-to-zoom" and then dragging about was completely unuseable. Leaving the small CPU's on schedutil and the big ones on powersave, I cant really say I noticed the lag. .But, since I dont have battery problems (i use an aggressive doze profile, and keep running apps under control, ie out of top -n 1;), I switched back to the standard gov.
One other little surprise is that I switched my IO scheduler to "noop" and although it *may* of possibly felt a tiny bit little more responsive, testing long running scripts, heavy in IO, actually ran slower.
Long story short, the powersave gov on the smaller cpu's induces lag. I did not check if the gov on the bugger CPU's saves much power.
