I just tried this, and it appears that the tweak to the file makes a difference in speed tests.
I'm trying to get my hands around how to actually test it in real-world situations.
So for CM7 - this would definitely be a nice addition to this already excellent ROM...

This should have been posted in the CM7 thread. Why start a new one?
Here is a flashable zip that will add the fix to an init.d script and will survive reboot. It checks to see if the value is 4, and if so changes it to 128. You have to apply it after each new rom flash.

This can be tested with adb pull.
Pull it with the setting at 4. pull pack the cm rom to a local folder. you will get speed stats. after the first pull, set the param to 128. pull again.
syntax from adb: adb shell echo 128 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
from terminal - just skip the adb.
one note, I tried this on my Aria - it broke adb transfers. Then I tried it again and it worked.
Before I add this to CM, I want to make sure it's reliable.

The gallery loads even faster.

Im at 128 with the update.zip I posted above, and I can adb pull and push to my hearts content. I am on nightly 18 BTW.

the correct way is to add it to init.rc - that's when I had a failure. but the failure is not consistent.

On cm, if you want to preserve an init script, you can do anyone of the following:
Save it in /sd-ext/userinit.d/
Save it as /sd-ext/userinit.sh
Save it as /data/local/userinit.sh
Use cm's backuptool, it runs on rom installation. Just save its path (without the leading "/system/") into /system/etc/custom_backup_list.txt
Code:
etc/init.d/04sdcardspeedfix

Apparent improvement
Just flashed the above posted zip on CM7 Nightly 18 - seems to be a dramatic improvement, at least in stats, on my cheapie class 6 card:
before update: Write 5 / Read 6
after update: Write 4 / Read 12
I did not conduct this test at all scientifically - just ran one speed test before and one after the update, so take it for what it's worth I guess...just figured I'd share.

I have it running as an init.d script and cannot make it fail. I do see this tweak posted in a lot of different forums.

Looks like this thread is now dead. This has been commited to cm7.

I find just one thread with the same question and that thread also has only 2 posts and the person who made the thread posted saying he found the answer but never mentions what the answer is.

I found something about placing a file in the init.d folder but the file was not specified so if anyone has the file in their init.d folder could they copy it to their sd card, upload it to dropbox or any other file share website and share it with me please.

Help please

Download "ADB Mask Controller"
install it, connect your phone with USB debugging enabled.
Make sure the connection is detected by the application, click on the refresh button beside SEARCH Option in the program.
in the first screen, you will find option "Push Zipalign" Do that.
Go to the screen titled "Zipalign"
select the optioin you want to use zipalign for user app or system app or both.
Caution : Use this tool judiciously, it has many advanced features used by ROM developers mainly. Like pushing an app to system, removing bloatware, Sql LIte, and many many more.....A wrong step may force you to reflash your ROM.
Hope it helped.

I clicked on 'push zipalign' a number of times and then clicked on zipalign data/app but nothing happens. It says zipalign not found. Push zipalign and try again or sth like that. I've rebooted my phone and i'm trying now,

Check if you have /system/bin/zipalign. If not try to put it there manually.
ADB controller might have problems mounting your /system r/w and it is read-only. Maybe you can mount it r/w and then try with controller (just guessing, though).
And you'll need to have the S03_zipalign made by kyrillos and hillbeast in /system/etc/init.d (or just /etc/init.d) posted earlier. For what I can tell it zipalign's all apps from /system/app and /data/app.

I second that esp rw option, its already there in ADB Controller. U can manually browse as instructed above. Its not that difficult, I am sure u will be able to do it well, reply here if u still get probs even after taking all steps as directed in my previous post and the post i quote above.

I thought I'd give this a go. I've moved the first file on the previous page to system/etc/init.d and the second file on the top of this page to system/bin. Is this sufficient?

you mean to say you have s03_zipalign in /system/etc/ini.d and zipalign file posted above as /system/bin/zipalign ??
i guess this should do for you .. awaiting to hear if u succeeded.

[Q] Keyboard Dropping/Missing Keystrokes?

Since I've gotten my Sidekick, I've noticed on most ROMs a horrible tendency to not register key-presses on the physical keyboard. There was one ROM early on that didn't do this (or very little) and one of the versions of RAGE was very good. I'm running GOV3.2 Bulky right now and it's not horrible, but it's noticeable. Does anyone have an idea of what might cause this? Thanks.

I wonder what the issue is that's causing it to show up on custom ROMs. Though, I've had it on the stock ROMs as well.

Have you tried this version of the kernel? Along with the removal of the keystroke logger, it also contains a patch that allows you to lower the keystroke timer delays... If you are experiencing dropped keystrokes, this could help, as the patch was designed for tht very issue.

Thank you!!!!!!!! I went ahead and dug into that thread. I do have that kernel already on my phone. I looked at the thread linked in that thread that gives a patch to adjust the timer delay and column delay in the kernel. HOWEVER, I'm not knowledgeable enough to apply that patch to my phone as it's given. Elsewhere in that thread, someone gave the commands to edit the settings manually through a terminal which I did through Android Commander on my PC and it worked wonders! Being the suspicious type, I guessed that the settings might not keep after a reboot. Unfortunately, that is the case and I had to reapply the settings after my phone finished restarting. So, I'll have to play with this a bit more to get it to keep, but thank you for showing me this!

You're welcome! That patch was made just for this issue. And yeah, it doesn't stick after a reboot, so we could either compile the kernel with chosen settings added in, or make a simple init.d script. I never did either one lol, was too lazy to try editing and building the kernel from source, and was on the stock ROM so I thought maybe it had no init.d support. You could probably create a file with those same commands used in Terminal, and throw it in your init.d folder to change the settings at boot.

I set my column delay to 30 and my timer delay to 1 and it now feels like I'm typing on a Sidekick again! I wouldn't know how to correctly compile the kernel myself with these settings changed. So, are there any devs out there willing to make a zip that can be flashed in CWM so these settings will become permanent?

To those interested in the commands I used to fix the keyboard, see below. If you reboot your phone, these settings will go away and you will need to input these commands again. For a permanent fix, someone will need to add them to a kernel that can be flashed. To use these commands, your phone must be rooted. I've successfully used Android Commander to enter these commands from my PC while my phone is connected via USB.
The current timer delay may be read with:
cat /sys/devices/platform/s3c-keypad/timer_delay
The default is 5 if I remember correctly.
A new timer delay may be set with:
echo 1 > /sys/devices/platform/s3c-keypad/timer_delay
The default 300 µs column delay value may be read with:
cat /sys/devices/platform/s3c-keypad/column_delay
A new delay may be set with:
echo 30 > /sys/devices/platform/s3c-keypad/column_delay
In either command, you may experiment with different values by changing the 1 or the 30 in either command to what you want. I believe the lowest is 1 and the max is 256 for the timer delay. If you damage your phone running these commands, that's on you. I'm just telling you what I did and feel worked for me. YMMV. Also, if you don't want to connect your rooted phone to your PC and want to use Terminal Emulator from the Play store, that will work too. You need to enter 'su' prior to running the above commands and grant the terminal super user permissions for the commands to take.

You are very welcome! All done, BTW. Posting my updates now.

Permanent Fix(Manual way)
Taking the timer_delay and column_delay tricks shown above...I was able to make an init.d script(pretty easy, tbh) but don't feel it merits an update.zip since it's so easy. What I did was:
1. go to /etc/init.d
2. find the last script(In GOV3.3 it's 18complete) and rename it - adding one to the sequence(In my case I renamed it to 19complete)
3. make a new file name 18keyboardfix(The number depends on your rom, really...like if you renamed the above file to some thing like 33complete, you'd call this 32keyboardfix. Easy? right?)
4. Open the file you just created and put:
Code:
!#/system/bin/sh
echo 1 > /sys/devices/platform/s3c-keypad/timer_delay
echo 30 > /sys/devices/platform/s3c-keypad/column_delay
5. Set the permissions to rwxr-xr-x or whatever the numeric equivalent is. (0755, iirc)
6. Reboot
7. (Optional) Recheck the values with the following commands:
Code:
cat /sys/devices/platform/s3c-keypad/timer_delay
Code:
cat /sys/devices/platform/s3c-keypad/column_delay
I take no credit for this fix. Really, it was all ged92781 for providing the commands. All I did was find a way to make it permanent(Well, it's just reset when the devices is turned off and the init.d scripts set it back to you desired values, but that's debatable on whether it's permanent or not...either way...it works and is a simple fix)

[GOVERNOR][2.6.39.4] Hotplug for Nvidia Tegra

Hello again xda, today I want to present something tiny, but nontheless important (in my view) for our old TF101 ...
The first working HOTPLUG governor for this device!
Q: What the hell is 'hotplug' ?
Hotplug Governor:
The “hotplug” governor scales CPU frequency based on load, similar to
“ondemand”. It scales up to the highest frequency when “up_threshold”
is crossed and scales down one frequency at a time when “down_threshold”
is crossed. Unlike those governors, target frequencies are determined
by directly accessing the CPUfreq frequency table, instead of taking
some percentage of maximum available frequency.
The key difference in the “hotplug” governor is that it will disable
auxillary CPUs when the system is very idle, and enable them again once
the system becomes busy. This is achieved by averaging load over
multiple sampling periods; if CPUs were online or offlined based on a
single sampling period then thrashing will occur.
Click to expand...
Click to collapse
As you can see, hotplug is able to deliver you the fastest experience and the most fps in game (kernel independant), but it also allows for completely switching off one core to save battery life. In my testings, that worked very well. I also found out, that with this governor, my TF is deep-sleeping like a baby. No governor around here (not even smartassv2 ... could deliver me this performance while maintaining a decent battery life).
Tested on EOS 4.2.1 with EOS4 kernel
But try out yourself:
NOTE: This works on any 2.X kernel available (my Harmony series, ELiTE series, KatKernel series, or any other kernel except my divemaster)
Code:
1) Download a terminal emulator (if you don't have one already)
2) Download the .ko module from [URL="https://dl.dropbox.com/u/31119007/xda/hotplug-tegra-2/cpufreq_hotplug.ko"]here[/URL]
3) Remember the path you saved the module to (or preferably move it into /system/lib/modules)
4) su
5) insmod path-to-module/cpufreq_hotplug.ko
6) Switch to 'hotplug' governor with your favourite tool.
If you were too lazy to read my instructions, this is for you ..

As always, have fun, share, and report back!

I have followed the instructions, do I have to run it every reboot or just this one off?
Nothing really happened when I ran it but I guess it just loads the module.
Cheers buddy

Must say thanks again for all the amazing work!

The only problem as 2 people discribe abovme is RR or Random Reboot.
Thats only problem.

sounds very promising i'll try it out and report if I get any RR's.
Getting error insmod: Can't open 'path-to-module/cpufreq_hotplug.ko'
Cd to my download folder which is where it is, am I doing something wrong?

Wow I derped that up, thx lol.
Was running fine at 1.2 decided to bump it up to 1.4 hit apply and it rebooted on me, is also didn't stick after reboot like others have said.

In here you may find how to make permanent the governor insmod.
Long story short is "add a script in /system/etc/init.d , it can be something like 91modules. . Add execution permission and it can contain the same code as before. Reboot and it should load your module at boot (be sure that the path to your module is right).
Also, you can do that in one line as root in a terminal. First, be sure that your /system is mounted as rw, not ro. If you don't know how to do that, as root, in a terminal, execute:
Code:
mount -o remount,rw /system
Then:
Code:
echo -e \#\!/system/bin/sh'\n'insmod [B]/path/to/module[/B]/cpufreq_hotplug.ko > /system/etc/init.d/91modules | chmod +x /system/etc/init.d/91modules
"
It should load automatically next time you reboot.
I created the 91modules file and done the editing and file permission in ES File Manager, but the above instructions should work flawlessly.
Don't thank me for this. Thank MapleSyrup

Posts like this are keeping my work up and my releases coming.
People like you are the reason I am putting this much effort in this kinda old device .
For those who experience SOD/RR with hotplug and can confirm it's not related to anything else, please gimme a dsmg/ksmg (I recommend using 'Lumberjack' from the playstore (made by Chris Trotman, EOS founder).
*NO* logcat, that isn't any useful for me in this case ..
I do now have 2 days uptime with hotplug governor, not a single SOD/RR, pretty much usage (wifi on all the time, a little Riptide GP, web browsing, most of the time playing music) and still got 20% left with EOS4 kernel while achieving full performance while needed.

In here you may find how to make permanent the governor insmod.
Long story short is "add a script in /system/etc/init.d , it can be something like 91modules. . Add execution permission and it can contain the same code as before. Reboot and it should load your module at boot (be sure that the path to your module is right).
Also, you can do that in one line as root in a terminal. First, be sure that your /system is mounted as rw, not ro. If you don't know how to do that, as root, in a terminal, execute:
Code:
mount -o remount,rw /system
Then:
Code:
echo -e \#\!/system/bin/sh'\n'insmod [B]/path/to/module[/B]/cpufreq_hotplug.ko > /system/etc/init.d/91modules | chmod +x /system/etc/init.d/91modules
"
It should load automatically next time you reboot.
I created the 91modules file and done the editing and file permission in ES File Manager, but the above instructions should work flawlessly.
Don't thank me for this. Thank MapleSyrup

I typed all this in and it wont survive uve a reboot. I placed the module in /system/lib/modules and typed that. When i see the | is that a new line or all one line?

You can make that code in 2 commands, 1st is all before the | and 2nd the command after the |.
In order to work your final 91modules should look like
Code:
#!/system/bin/sh
insmod /system/lib/modules/cpufreq_hotplug.ko
In order to test if it's working you cat try to run it from the terminal (it may need "su" before)
Code:
./system/etc/init.d/91modules
If it's not complaining about not being executable, you may test to see if it's loaded with "lsmod".
If it's loaded it surely will survive the reboot.
I hope that helps you.

Looks like it created the 91modules file in init.d but when i try to set permissions using chmod +x it says bad mode. Maybe thats why it isnt working, wrong permissions.

Indeed the chmod +x command doesn't work.
You may use ES file explorer to set file permissions but also you need to allow it superuser access, mount /system as writable and "up to root" and mark execute and write to the user. At the end the file should have the following permissions: rwx r-- r--

Ill give that a try and see if that does it. Thanks!

thanks

Minfree settings in CM12 Roms

As there are again and again discussions concerning the minfree settings in CM12 roms, I decided to open this thread. If a moderator thinks, this is the wrong place for this thread, just move it, to where it belongs.
Obviously, since the last builds of CM12, the settings for minfrees cause some trouble. After a clean install of any rom, the minfree settings in trickstermod and in fauxclock are completely empty. In fauxclock the settings for OOM (out of memory) Score as well. Some people entered them manually, but I'm afraid, this won't help.
To really solve this, you have to do the following steps: open your file explorer, go to sys/module/lowmemorykiller/parameters. There you will find 5 files. Two of them do not have correct permissions. The first one, called adj, is for the OOM Scores. The other one, called minfree, is, you won't guess it, for the minfrees. :fingers-crossed:
As you see, both of them have only write permissions, but no read permissions. So I guess, the system will ignore these settings completely. I checked this, using cool tool from play store, very nice tool to show for example the actual free ram in your status bar. And in deed, the ram went down to 25MB, after I had opened a handful apps, and then my phone stopped working. I only could do a reboot.
Now the solution, which is quite easy: change the permissions into rw-rw-rw (666), and maybe change the group under owners into root (I'm not sure, if this is necessary, but it does make no problems, so why not).
Et voilà - if you now open trickstermod or fauxclock again, you will see the preset parameters. As you can see also, the minfrees there are really high. In another thread, there have been suggested the following settings, which are a good standard:
trickstermod 48/60/72/84/96/120
fauxclock 12288/15360/18432/21504/24576/30720
Important: In fauxclock, the minfree settings are not made in MB. You have to enter the so called "pages" for minfrees, which I can't explain exactly, what this is. In general, if you want to change minfrees in fauxclock, just take the settings in MB, you want to, and multiply by 256. This will give you the correct values.
BTW I don't think, it's a good idea, to change the OOM Scores, as long as you do not know exactly, what you're doing.
So, hopefully I could help a bit and clear some things up. But the final question to the CM devs remains:
is this a bug or is this a feature?

With me, those files were already chmod 666, owner root. I use latest liquidsmooth rom. What i did, prior reading your post, was that i set minfree in trickster, from my presets, than immedatly switched to faux, parameters were there, pressed apply, switched set on boot and rebooted. After that minfree r sticking in faux and trickster. Guess that my actions leaded to what you have described. Anyway, your way is much more convinient - at least one app less to use

I don't get it... The directory you mentioned is empty on my one s as well as on my nexus 10 both with cm12.
However my settings stick since I use fauxclock.
One more thing I don't get is in fauxclock. It says "kilobyte" explicitly in the minfree settings although you said (and it stems to be) this strange pages value....

You have to use your file manager with root permissions. Depending on which file manager you use, this can be done differently. The inbuilt CM12 file manager can be given root permissions in settings, in Root explorer for example you have to mount the directory as r/w.
An yes, you are right, fauxclock says, the settings are in kilobyte, but this is not correct. If you succeed to open the minfree file with your file manager, you will find there exactly the values, you have entered in fauxclock.

Damnit, you're right. Solid explorer doesn't show the content of the directory.... I use it a long time and always had the feeling solid explorer shows me all files...
Cm file manager works, thanks!

It does work with solid explorer as well. The point is, there is no option, to set root permissions manually in solid explorer. So the trick is to create a situation, where solid explorer will ask for root access. For example: long press any folder in your system root, tap properties, tap change (attributes) and now press OK, without changing anything. You will be asked for root access.
Now everything should be fine!

got a problem.
parameter file is empty.

For solid explorer, just try to open /data and it will ask for root permissions. I do it every time I flash my phone.

Thanks a lot man! I wasn't aware of the skewed minfree files. Was setting them in Trickster and wondering why the apps keep shutting down on me when multitasking. Great work

They will still close even so...just not so obvious

Uh yes obviously. However they were actually closing the instant i opened another app. Couldnt even keep two apps open at the same time, that was pretty bad.

Yes, I know what you mean. Was the same for me. Having better minfree settings that stick after a reboot helped but didn't solved the issue completely. But at least now phone is usable. I put my hopes in that Google patch they'll release with 5.0.3

Thanks for this thread, I changed the permission with "chmod 666" using adb shell, but after a reboot, the files were back to write-only mode, is it normal ? How do you make it permanent ?

If it's reverting, I guess the only way would be through an script that runs at boot time. But it's strange, the permissions should stick once set...

I used a file explorer with root permissions like root explorer or ES file explorer. My permissions are actually rw-rw-rw, both for adj and minfree file. I guess, this is 666? And they stick after a reboot. But honestly I am not quite sure, if I changed something else. IIRC, I might have changed the permissions for system/etc/init.d/90userinit to rwxr-xr-x. Maybe you want to check this, too.

Well, they don't stick because init.rc sets them to chmod 0220 on boot. That makes me wonder if maybe it was supposed to be like this? I wanted to change it but I don't want to screw anything up. There is a dedicated section for low memory killer in init.rc and only things there are chmod 0220 for those two files and chown for them - so basically the things that we are fixing in this thread. A bug or a feature?

Thanks for this hint! Indeed, this might be the other thing, that I had changed. In CM11 roms, the described permissions in init.rc are 664 - both for adj and minfree file. I am not quite sure, if this helps, but it's worth an attempt. You can change the permissions in init.rc to 644, reboot and see, if the permissions for adj and minfree are sticky now. I just did this ,and everything is fine -so you can try without risk, I guess. But I must say, I hadn't the problem before, that the permissions for adj and minfree were reset after reboot. Could be related to the changes in init.rc, but I am not sure.

A weird thing: I made a backup and tried anyway yesterday but after a reboot my init.rc restores itself to normal. I tried another time: Modified the values and saved. After reopening it's still there and it stays there but only until I reboot the phone. After reboot the permissions are not set correctly and init.rc restores itself to original state. Is there something I do not know about modifying init.rc? Because that is the first time I try to do something with it.
