Properly sync music between itunes and Android with rsync?

Properly sync music between itunes and Android with rsync? - Android Software Development

Hi all,
I've been trying hard to replicate the 'echo mode' of SyncToy (Microsoft freeware) using rsync. If you want to understand how this mode acts, here is an illustration:
ht***tp://ww***w.laboratoire-microsoft.org/articles/win/synctoy/images/echo.jpg (sorry, i can't publish urls from my noob account)
Basically, the DEST folder is never analysed and only the changes made on the SOURCE folder between date 1 and date 2 are repeated on DEST folder.
Assuming that i never make any manual modification to my DEST folder this is the perfect solution.
Actually, i presume iTunes acts exactly this way and that's why syncs are so faster with iphone and ipod.
Why do I want to replicate this mode?
My sdcard is a class2 and it's really sloooow. Each time I run rsync, it tries to analyse my mac partition (ssd) AND my sdcard, and compare the two directories....which takes at least 1h30 for my whole library even if only 2 files have been added to SOURCE folder between date 1 and date 2!!
SyncToy is a Windows program, I use a macbook
All my music library is on my mac partition
Note: for the moment i run synctoy through a virtual machine with my itunes library folder being shared. It's working but it's not the best solution...
So if there is any rsync guru here: do you think there is any possibility to recreate this 'echo mode' using rsync?

Is rsync really what you want, given you don't need any of the clever things it can do?
My shell scripting knowledge is very sparse, but wouldn't something like this do:
find $SourceDir -mtime +1 -mtime -4 -type f -exec cp {} $DestDir \;
where in this example it (maybe ) copies any file last modified between 2 & 4 days ago (inclusive & exclusive respectively) from $SourceDir to $DestDir.
NB This is untested, I'm clueless & it also might need to be a bit smarter to handle anything other than a flat file structure (in which case replace cp with something that will make each ancestor directory if absent from the destination & will then cp into that), so you have been warned.
[Edit:] Yes, you'd need something like cpio instead of cp. If you're interested search for info on "cpio -pd"

Otherwise I was thinking about making a script:
1. create a simple text file with lines like that "/full/path/to/file/filename.ext;SizeInByte;LastModificationTime" for each file file in SOURCE dir at date 1.
2. At date 2, create a new similar text file
3. Compare the 2 text files and keep only different lines
4. Differences coming from date1 text file are deleted from DEST dir and differences coming from date 2 file are copied/overwritten.
Does your command deletes files that have been deleted in SOURCE dir between the two dates?
Isn't cpio for archiving, like tar,gz2,etc...?

Deletes? No, that would be impossible if you aren't allowed to scan the destination folder, /unless/ you follow a plan such as you outline above. I didn't realise you required this.
cpio with the -p option (passthrough) is effectively just a copy command which maintains the directory hierarchy.
Your above strategy sounds best. For the stored records, I think I'd use:
find $Dir -type f -printf %p\\0%s\\0%A+\\0\\n > file.log
as you can rely on \0 not turning up in any of the fields it separates; the \n just added to tidy the log up should you wish to check it in a text editor. Oh & the %A+ date format so that if you need to order two dates a lexical comparison is adequate, whilst still being human readable.
That said, you don't appear to want to use the size or time fields, & not storing them would slightly simplify the code. <-- Sorry, that's rubbish on my part; how else would you notice when a file had changed.
Then probably compare them using diff:
diff -a file1.log file2.log > diff.log
Parsing diff.log should then be a trivial matter of checking each line in turn & for those commencing <, remove the named file; for those commencing >, copy the file over.
It's possible for a file to change resulting in both lines above appearing in diff.log for the one file. In that case you obviously need to process the removal first & it's not obvious to me if < will always appear in the log before >, so maybe safer to handle all the < removals first then handle the > copies.
OTOH if the above assumption is safe /&/ you modify the above to process the directories as well as files, you might be able to get away with making the diff.log parsing step a simple matter of applying a suitable regexp match & replace to each line in the diff.log, with the resulting output being a script that does the removals & copies. That'd be quite cool.

>> [That said, you don't appear to want to use the size or time fields, & not storing them would slightly simplify the code.]
Well, if I just add an albumart to my music file or change a tag, the filename will not necessarily change but the ModificationTime will, for sure.
I'll have a look at your shell commands.
Btw, thanks a lot for helping me

I know. Stupid oversight on my part which I realised just before you posted
I edited my post to reflect this & had to resort to colouring the incorrect comment as xda-dev doesn't seem to support any strikethrough markup.

I managed do the script but there is still one issue: at the beginning, when I declare the path variable, I cannot include a path with one or more spaces. For the moment, I just created symbolic links.
Code:
left=$HOME"/Desktop/SyncAndroid/left"
right=$HOME"/Desktop/SyncAndroid/right"
temp=$HOME"/Desktop/SyncAndroid/temp"
rightSED=$(echo $right | sed -e 's/\//@@@/g')
leftSED=$(echo $left | sed -e 's/\//@@@/g')
mkdir "$temp"
cd $left
find . -type d -print | sort > $temp/LOG_leftD
cd $right
find . -type d -print | sort > $temp/LOG_rightD
cd $temp
diff -a LOG_leftD LOG_rightD > diffD

UPDATE 1: the code to take $ symbol (like in Ke$ha) in file path or filename
UPDATE 2: log files are sorted to fix some library updating bugs
NOTE: this scripts scans the right AND the left folder. In fact, I realised that scaning the music folder in the class2 sdcard only took 1-2seconds... Btw, I still don't understand why rsync takes so much time to sync the two folders (even if i don't ask for checksums comparisons)...

Glad you were able to devise a solution. Sed always gives me a headache as I can never remember what needs to be escaped & what doesn't. Clearly your grasp of shell scripting is better than mine.
Re the space in path issue, I take it it isn't adequate just to escape each space? The speed of rsync is puzzling. Is it definitely not connected to the sdcard? If you apply rsync to the same data, but with both directories on your pc, do you get the same performance differential?

I've tried doing this sync using rsync:
between 2 folders on my HDD, only modifications are done to the DEST folder
between a folder on my HDD and another one on my sdcard, each file file is copied all over again each time... which, obviously, takes time

I DID IT! If we look at rsync manual:
Code:
When comparing two timestamps, rsync treats the timestamps as
being equal if they differ by no more than the modify-window
value. This is normally 0 (for an exact match), but you may
find it useful to set this to a larger value in some situations.
In particular, when transferring to or from an MS Windows FAT
filesystem (which represents times with a 2-second resolution),
--modify-window=1 is useful (allowing times to differ by up to 1
second).
My sdcard partition is in FAT...
So the final rsync command which works really well
Code:
rsync -arv --delete --force --modify-window=1 "/Users/XXXXX/Music/iTunes/iTunes Music/Music/" "/Volumes/NO NAME/Music"
a for archive mode
r for recursive deletions (combined with --force)
v for more verbose (optional)
--delete to delete any file in DEST dir that is not in SRC dir
--force to force the deletion of not empty folders
--modify-window=1 to tolerate 1sec of difference between two corresponding files.
So forget about the previous script. This single commandline replaces it.
phewww

Awesome. Congratulations on figuring it out

[Q] compile own kernel? configuration

I used rotohammer's method for backing up the AT&T Galaxy Tab and it worked wonderfully. I compiled the GT-P1000_Kernel patched with SGH-I987_Kernel and did a standard make and then flashed the zImage onto the galaxy. It resulted in kernel panic. Does anyone know what parameters to use with make or configuration changes that need to be made?
Thanks
ps. when I used heimdall, I only "heimdall flash --kernel zImage".

I also couldn't find a config.gz in the /proc dir. Does anybody know why it is missing and what has taken its place?

success at last
Yay, it works now! thanks roto for the initramfs tip.

what kind of modification did u make to the kernel? do you mind sharing?

[Q] how did you compile your own kernel?
Hi,
I'm in disperate need to do this. I have downloaded the sources from samsung opensource -> followed the instruction in the README.txt -> compiled the kernel and the modules successfully -> used the initramfs from the stock zImage -> but when I flash the zImage (Size ~ 432 KB) I get kernel panic.
I do not think it is possible to boot in verbose mode or have a serial port console log.
letolkki: please share with us how you did it? how did you compile a zImage which boots.??????
share with us please!

I used make menuconfig to specify the location of the initramfs (compression to none). Do not use the build script above the root as that seemed to mess things up for me. The size of my kernel is approx ~5meg with the initramfs included and ~3 without. Then used Heimdall to push it on.

I didn't make any mods as of yet. Just a quest for knowledge and tinkering. Just making sure I can when I need to.

What exactly did you modify? Here's my config, as related to INITRAMFS:
CONFIG_BLK_DEV_INITRD=y
CONFIG_INITRAMFS_SOURCE=""
CONFIG_RD_GZIP=y
CONFIG_RD_BZIP2=y
CONFIG_RD_LZMA=y
CONFIG_INITRAMFS_COMPRESSION_NONE=y
# CONFIG_INITRAMFS_COMPRESSION_GZIP is not set
# CONFIG_INITRAMFS_COMPRESSION_BZIP2 is not set
# CONFIG_INITRAMFS_COMPRESSION_LZMA is not set
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
My kernel size is only 2.9 megs. What else did you specify that has your kernel at 5 megs?
Thanks

you don't have the initramfs source file specified. Put the complete path to the initramfs in the config.

Even when I specified the file location generated during the compile, it still didn't work...size only 3 meg. Are you using the ramdisk.img generated and output into Android/out/target/product/...? Or, did you pull boot.img from the device and split ramdisk.img from the kernel?

yep, i pulled it from the device

Would you please tell me how you did it exactly? I've been attempting over the past several hours and haven't been able to find a tool that would split boot.img. They keep telling me that it's not a valid image, but I pulled it from the device.

I used the script from
http://forum.xda-developers.com/wiki/index.php?title=Extract_initramfs_from_zImage
to get the initramfs from the zImage pulled from the device.

Much appreciated! I'll try this later tonight. Right now, I need a break...

I used verizon_zImage from ClockworkMod, but it fails the extraction with a gzip invalid compressed data--format violated error. How can I pull the zImage directly from the phone? It seems that boot.img doesn't work either.
Thanks

Here are the error messages I'm receiving for both verizon_zImage and boot.img, which I pulled from the GT:

So do you guys have working kernels ?
I know from my Nexus days that custom kernels can made a massive difference to performance on the beast, so I am looking forward to seeing what people can do with the TAB
Keep up the good work !

I've built my own kernel to see if I could work around the dialing limitation on my VZW tab. Right now, it crashes randomly, but it does boot! I'm looking into the difference between the international version of Onedram and Verizon's version and why Verizon includes a OnedramRecovery unit. My kernel doesn't reference OnedramRecovery and I made more mods. So, I haven't isolated what is causing the instability. Right now, I'm back to Koush's kernel. I'll keep you informed on my progress.

Arch linux chroot

I started using Arch some months ago and I really enjoying it. Coming from a released based distro, it feels really nice been able to choose exactly what you want to run in your system and always have the packages up to date. For a while I have been planning on running ubuntu in my transformer but I just don't feel too comfortable with ubuntu , so decided to run arch in my transformer. I couldn't find a tutorial so I scavenged the net and found bits and peace that I put together to make this tutorial. What I like about arch is that I am in control of my system and I can run exactly what I want, thanks awesomely documented Arch!
This is a tutorial that will show you how to run Arch Linux in a chrooted environment within your Asus Tarsnformer. I will not provide a simple script that if you run it will do everything for you, instead I will teach you how to make your own installation by grabbing all necessary elements.
You will need:
Arch Live image: Go to http://archlinuxarm.org/developers/downloads and grab the omap 3/4 package.
Install environment: It can be your internal storage or a sd/micro card. Here I will show how to use the micro sd card.
Script for starting the chroot: I grabbed mine from http://forum.xda-developers.com/showthread.php?t=1517993&highlight=chroot and did some modifications. Thanks-miska-
Rooted Asus Transformer(Prime?) with Terminal: You need root to mount the file system and loop devices. In theory this should work in the Prime too.
Linux Machine
Step 1:
For installing arch in a (micro)sd card (I prefer micro as I don't need the dock for using it), first you need to format the card and make two partitions. (I used gparted) Make one partition fat and assign a small amount of space(I have a 4gb micro and assigned 128mb to the fat partition), then make the rest ext4. Make sure the fat partition is first and the ext one is second.
Step 2:
Now as root you need to extract the package in the ext partition of your card. REMEMBER to be root, I got stuck thinking there was something wrong with the package I downloaded but it was that I was unpacking as normal user.
Code:
# tar -c /path/to/extpartition -xzf ArchLinuxARM-omap-smp-latest.tar.gz
Now you have a arch environment in your (micro)sd card.
Step 3:
In your asus transformer create a folder called 'arch' in the root of your internal storage.
Code:
#mkdir /sdcard/arch
Or use a file manager.
Now place this script somewhere in your transformer, I usually keep it in /sdcard/Downloads
Code:
#!/bin/sh
# Modify this according to your needs
DEVICE="/dev/block/mmcblk1p2"
LOOP="no"
# Maybe this as well
MNT_PATH="/mnt/sdcard/arch"
# Modify only if you know, what are you doing
BINDS="dev dev/pts proc sys mnt/sdcard"
ANDROID_BINDS=" /system /data "

fi
MY_MOUNTS="$MNT_PATH$2 $MY_MOUNTS"
}

#echo '#!/bin/sh
#export TERM=linux
#export LANG="en_US.utf-8"
#export EDITOR="busybox vi"
#alias vi="busybox vi"
#precmd() { :; }
#if [ "`whoami`" = root ]; then
# export HOME=/root
# export USER=root
# hostname -F /etc/HOSTNAME
#fi
#if [ -z "$CHROOTED" ]; then
# export CHROOTED=yes
# export HOME="/home/opensuse"
# export USER="opensuse"
# su opensuse
#fi
#' > "$MNT_PATH"/etc/profile.d/tweak.sh
#fi
export PATH="/bin:/sbin:/usr/bin:/usr/sbin:/system/xbin:/system/bin"
# Chroot
chroot "$MNT_PATH" /bin/bash
#chroot "$MNT_PATH" /root/init.sh
# Cleanup
echo "Umount everything"
for i in $MY_MOUNTS; do
umount -l $i
done
Step 4:
Chmod +x the script and run it as root.
Code:
su
#chmod +x scriptname.sh
sh scriptname.sh
The script will mount the ext partition of your (micro)sd card in /sdcard/arch and will chroot into it. It also does other really nice things, such as mounting your android partitions to /mnt so you can access them from within your arch environment. I have disabled some lines that are used to set up a some environment variables, but you should still be able to get a fully functional command-line environment and you can enable them and modify them as you want.
Step 5:
The rest is completely up to you, now you have arch running in your transformer. But what!? You need X?! really???? Ok, so lets create a vnc server so we can remote into it.
Your network connection should work, so the first thing to do is an update
Code:
#pacman -Syu
Now install xorg
Code:
#pacman -S xorg-server xorg-xinit xorg-twm xorg-xclock xterm
Now install a vncserver
Code:
#pacman -S tightvnc
And now this is the tricky part(And I spent a lot of time in this).
I grabbed this script from the UbuntuInstaller post. This is the script they use for setting a resolution at each boot. What I did was to remove the resolution prompt and fix the resolution to 1280x752(fullscreen) and remove some ubuntu stuff. I also added an export for HOME and USER that will allow you to run 'vncserver' as root.

Place this script in /root/, give it the name 'init.sh' and make sure it is executable(chmod +x). Now in the previous script comment the line:

and uncomment the line
Code:
chroot "$MNT_PATH" /root/init.sh
Step 6:
Now you should be able to start a vncserver with twm as your window manager and a xterm.
You can now go to
https://wiki.archlinux.org/index.php/Desktop_Environment
or
https://wiki.archlinux.org/index.php/Window_Manager
and set up the desktop environment that you like the most.
Remember that you need to set up the graphical environment to start manually and not at boot. In a normal environment you would usually use 'startx' which will read the .xinitrc file and run the programs from there. In our case put everything that needs to go into .xinitrc into ~/.vnc/xstartup. An example of my ~/.vnc/xstartup
Code:
#!/bin/bash
xrdb $HOME/.Xresources
exec startfluxblox
This will start an empty fluxbox window manager.

Android 4.2.2 (PAC, CM10.1, etc): Mount CIFS share on /sdcard (incl. nls_utf8)

With Android 4.2's multi-user stuff and the dreaded "0" folder, Google broke mounting of CIFS shares for good. (They basically implemented something utterly useless for my needs, and broke something I need on a daily basis.) Cyanogenmod fixed that for mounts outside the /storage hierarchy, but many apps can't go there. And with 4.2.2, Google made using adb on the device very annoying as well, which adds to problems for a workaround for mounting shares in a useful place.
So I looked around for various fixes for that issue and compiled those into one method that works perfectly well for me on a P6810 running the current PAC ROM 20130629. It should probably work for any other CM10.1 or PA3.6x-based ROM as well. A nls_utf8.ko module compiled for the Nexus 10 is included as well, which can be loaded via punchmod (at least in PAC), so you can access shares with Ümläüts in them.
Prerequisites: SManager, SMWidgets, and a working Busybox install (I use Stericson's Busybox Installer).
1.) Extract nls_utf8.ko and punchmod from the attached .zip file and put them in /system/lib/modules. You can put them in some other place as well, but my scripts need to be adjusted then. Next, give the files sufficient permissions:
Code:
chmod 644 /system/lib/modules/nls_utf8.ko
chmod 755 /system/lib/modules/punchmod
2.) Optional: if you want the module to auto-start, create a file called 00punch-nls_utf8 (or whatever you like) with the content below, put it in /etc/init.d and chmod it to 755. To check if nls-utf8 is loaded after a reboot, type lsmod in a terminal window or adb shell - it should display the module name. If punchmod auto-detection fails, read here how to get the right vermagic string for your device: http://forum.xda-developers.com/showthread.php?p=41920265#post41920265
Code:
#!/system/bin/sh
sleep 10
/system/lib/modules/punchmod /system/lib/modules/nls_utf8.ko ""
3.) Here's the script that mounts a CIFS share. Edit the settings on top and either put your correct vermagic string as well, or delete the "$VERMAGIC" part in line 22 and try your luck with auto-detection. I put some sanity checks in the script, but it might not work for all directories in /sdcard (or, /data/media/0, to call it by its 'real' name/location). If you don't want to use the nls-utf8 module, just delete lines 18-23, and iocharset=utf8 in line 67.
Name the script mount-music.sh or something, put the script wherever you like, open SManager and navigate to the script. Run the script with SU permissions. If everything goes well, it will ask you to accept an adb RSA key, and then adb mounts the share. You can also add a desktop widget for quick access to the script with SMWidgets.
Code:
#!/system/bin/sh
# Your settings here
IP="192.168.1.123"
SHARE="Music"
USER="yourusername"
PASS="yourpassword"
MOUNTPOINT="/data/media/0/cifs"

if [ `lsmod | grep -o cifs` ] ; then
:
else
insmod /system/lib/modules/cifs.ko
fi
# Load nls_utf8 brute-force style (if it isn't already loaded)
if [ `lsmod | grep -o nls_utf8` ] ; then
:
else
/system/lib/modules/punchmod /system/lib/modules/nls_utf8.ko "" "$VERMAGIC"
fi
# Check if cifs $MOUNTPOINT dir exists, create it if not, give sufficient permissions
if [ -d $MOUNTPOINT ] ; then
:
else
mkdir $MOUNTPOINT
fi
chmod 755 $MOUNTPOINT
# Check if $SHARE directory is empty - if not, unmount the share
if [ "$(su root -c busybox ls -A $MOUNTPOINT/$SHARE 2> /dev/null)" == "" ] ; then
:
else
/system/xbin/busybox umount -l $MOUNTPOINT/$SHARE
fi
# Create $SHARE directory if necessary, give sufficient permissions

# Starting adb

# PORT=`getprop service.adb.tcp.port`
setprop service.adb.tcp.port 5555
adb start-server
cat /sdcard/.android/adbkey.pub >> /data/misc/adb/adb_keys
stop adbd
start adbd
adb connect localhost
# Make sure we only use the first device (sometimes there is more than one)
SERIAL=`adb devices | head -n2 | tail -n1 | cut -f1`
if [ "$SERIAL" = "" ] ; then
echo "ERROR: Could not find ADB device.";
fi
# Mounting share via adb
echo Mounting share via adb...
adb -s $SERIAL shell su root -c /system/xbin/busybox mount -t cifs //$IP/$SHARE $MOUNTPOINT/$SHARE -o user=$USER,pass=$PASS,iocharset=utf8,cache=none,directio,CIFSMaxBufSize=130048,rw,file_mode=0777,dir_mode=0777,uid=1015,gid=1015
# If you started adb, then stop it here for security
adb disconnect localhost
stop adbd
PORT=`getprop service.adb.tcp.port`
setprop service.adb.tcp.port $PORT
start adbd
# Show some results
RESULT=`mount | grep $MOUNTPOINT/$SHARE`
if [ "$RESULT" = "" ] ; then
echo "FAILED! //$IP/$SHARE could not be mounted."
else
echo "SUCCESS! //$IP/$SHARE has been mounted on $MOUNTPOINT/$SHARE."
fi
echo
echo All done. You may close this script window now.
4.) This is the script to unmount the share. Name it unmount-music.sh or similar, and edit your settings at the beginning of the script. Again, run it in SManager with SU permissions, and add a desktop widget with SMWidgets if you like.
Code:
#!/system/bin/sh
# Your settings here
SHARE="Music"
MOUNTPOINT="/data/media/0/cifs"
# Check if $SHARE directory exists
if [ -d $MOUNTPOINT/$SHARE ] ; then
# Check if $SHARE directory is empty - if not, unmount the share
if [ "$(su root -c busybox ls -A $MOUNTPOINT/$SHARE 2> /dev/null)" == "" ] ; then
echo "$MOUNTPOINT/$SHARE is empty."
else
su root -c busybox umount -l $MOUNTPOINT/$SHARE
fi
fi
# Show some results
RESULT=`mount | grep $MOUNTPOINT/$SHARE`
if [ "$RESULT" = "" ] ; then
echo "SUCCESS! $MOUNTPOINT/$SHARE has been unmounted."
else
echo "FAILED! $MOUNTPOINT/$SHARE could not be unmounted."
fi
echo
echo All done. You may close this script window now.
Hope this helps some of you. It sure stumped me how incredibly convoluted this simple and much needed procedure has become on Android 4.2.2... just because of that multi-account stuff and new restrictions on adb.

Thanks man, looks awesome, I am going to try it on my 6800.
Do you know how to mount ext4 or ntfs sdcard on CM10.1 based roms?

Removed the original post, still trying to make it work!
I checked vermagic in some existing ko files and found that it is exactly the same as yours.

You can try loading the UTF8 module without vermagic string as well, it should work on PAC. Or, make sure you have a blank space at the end of the vermagic string, it is required. Maybe read the short tutorial here: http://forum.xda-developers.com/showthread.php?p=41920265#post41920265

I finally managed to mount cifs shares, after loading original cifs and punmode load of nls_utf8.ko.
But I mounted it with cifsmanager. The script always shows "failure to mount" !

[SCRIPT] Log CPU Usage with interval (Linux)

Hey guys, I've just decided to get inside of the Android development world. Anyways, I'm mostly a fan of Linux, so I've made my first Linux script, I know it's simple, but I've never interacted with the user before, or picked an output. When I knew that Android made use of Linux in its core, my interest on working inside it grew up faster than ever.
In my script, firstly, you type the filename. For compatibility reasons, it'll everytime save to /sdcard/filename. Then, it will ask you how many times you want the script to log everything, and lately, every how many seconds should it save everything to the file.
The script will save, before every entry at the log, the screen status (if it's on or off), that can help to, for example, if your device has been lagging as a result of a bad screen driver or UI error.
Last thnig: it also works on recovery (maybe it give some error, and if no dumpsys is present on your recovery's ramdisk, it'll save everything as OFF).
Remember to send it anywhere excepting from /storage and any sbudir, it won't work as the Android permissions system blocks script execution on those dirs.
Code:
clear
# Wipe $logfile content in /sdcard (if any existing)
echo "Please type the filename where you want to save the log: "
read -r logfile
echo "" > /sdcard/$logfile
echo "Deleted previous log."
echo "SCREEN | CPU" >> /sdcard/$logfile
#cont=60
cont=1
#SHOWLOG=X
echo "Please type how many times the cycle must repeat: "
read -r maxcont
echo "Please type how many seconds will the interval take: "
read -r maxmin
clear
# Here it counts how many times the logging script has been ran
while [ $cont -lt $((maxcont + 1)) ];
do
# That nested while takes control of how many seconds have passed in the current cycle
while [ "$contmin" -lt "$maxmin" ];
do
contmin=$((contmin + 1))
sleep 1
clear
echo "C: $cont/$maxcont - T: $contmin/$maxmin"
done
# echo "$maxmin seconds passed."
# Logs the fist line of "busybox top" to a var
LOGVAR=$(busybox top -d 1 -n 1 | grep "idle")
# Logs the screen state (on or off) to another var
SCREENSTATE=$(dumpsys input_method | grep mScreenOn | tr -dc '[:alnum:]\n\r' | tr '[:upper:]' '[:lower:]')
# Saves a string that tells what it should expect if the screen is on
SCREENSTATEON="msystemreadytruemscreenontrue"
if [ "$SCREENSTATE" == "$SCREENSTATEON" ]
then
echo "ON: $LOGVAR" >> /sdcard/$logfile
else
echo "OFF: $LOGVAR" >> /sdcard/$logfile
fi
cont=$((cont + 1))
contmin=0
done
echo "Show logged values? [Y/N]"
read -r SHOWLOG
case $SHOWLOG in
[yY] | [yY][Ee][Ss] )
cat /sdcard/$logfile
;;
[nN] | [n|N][O|o] )
echo "Ok, goodbye. You'll see a what you've asked me to log in /sdcard/$logfile";
exit 1
;;
*) echo "You must write Y or N to continue."
;;
esac
exit 0
For example, save it as script.sh (remember to save it using Unix codifcation, if you're running Windows, else, it'll tell you that it's unable to find many binaries, as long as Linux isn't ok with CR+LF and requires LF as newline). Then, send it to the sdcard (over USB or adb push script.sh /sdcard/) , now, run ADB shell. Type the following commands:
Code:
su -c "cp -f /sdcard/script.sh /data/local/;chmod 777 /data/local/script.sh"
Then, if you want to run it:
Code:
su
sh /data/local/script.sh
That's all, I hope you enjoy it and not so many people kills me for explaining and feeling so grateful for that simple script.

Set Maximum CPU frequency on any Android ROM for the HP TOUCHPAD

The maximum and minimum cpu frequencies allow by the Kernel can be set to all the Android ROM ever made for the HP TOUCHPAD until now and forever!
This is apply as a native setting ( as shipped from the factory, we could say )
The ROM will not be modify, no need for ROOT access or install SuperSu or any Apps.
It can be done to an existing installed ROM, no need to re-flash, is safe and will not damage your installation or prevent you from using your TP. Even if you do not do it right, you will get your TP running as always.
This is only done in a Linux OS, I am using ubuntu, which it can also be run under a Virtual Machine in any other OS.
1. Get the boot.img from the zip ROM or the current uImage from the TP boot directory.
(The boot.img must be copy to the root/hpboot directory of the PC, not on the tablet)
2. Run each of this commands separately in terminal in the directory the boot.img is.
dumpimage -i boot.img kernel.uImage
dumpimage -i boot.img -p 1 ram
dd if=ram of=ramdisk.img.gz bs=64 skip=1
gunzip ramdisk.img.gz
mkdir ramdisk; cd ramdisk
cpio -i < ../ramdisk.img
3. Go to the ramdisk direcoty and open this file in a text editor:
init.tenderloin.power.rc
Copy and Paste under # CPU Scaling and # CPU boost the following:
Note: You can add different settings to each cpu0 or cpu1.
Different frequencies to each and also assigned different Governors to each cpu.
You have total and individual control.
# CPU Scaling
# Replace the numbers at the first two lines at the end with the frequencies your TP can handle.
# Replace the numbers at the last two lines at the end with the frequencies your TP can handle.
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 192000
write /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq 192000
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1782000
write /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq 1782000
# Configure Performance Governor
# This is optional, but it will speed boot time using both CPU at maximum frequencies.
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor "performance"
write /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor "performance"
# CPU boost
# Set your desire speed can not be higher than your maximum frequencies.
write /sys/module/cpu_boost/parameters/boost_ms 20
write /sys/module/cpu_boost/parameters/sync_threshold 1782000
write /sys/module/cpu_boost/parameters/input_boost_freq 1782000
You can configure the type of governor after the system finished booting on this line. Is all up to the Kernel and your choice, but interactive is good.
# Configure Interactive
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor "interactive"
write /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor "interactive"
4. Save the changes and repack the ramdisk with kernel.
Open Terminal in the ramdisk folder and paste:
find . | cpio --create --format='newc' | gzip > ../ramdisk_Pack.img
5. Go to the folder where the original boot.img file is and you should have a file ( ramdisk_Pack.img )
Paste the following two commands:
mkimage -A arm -O linux -T ramdisk -C none -a 0x00000000 -n "TENDERLOIN MAX CPU" -d ./ramdisk_Pack.img ./ramdisk.uImage
mkimage -A arm -T multi -C none -n "Tenderloin Android MAX CPU" -d kernel.uImage:ramdisk.uImage uImage.Android_MAX_CPU
6. There is a file name uImage.Android_MAX_CPU in the same folder as your original boot.img, copy it to your TP boot directory and reboot.
If you enter a wrong frequency and it did not finished then do a hard reset and select the other boot image and use it as always. If it finished booting then you are running faster than ever!
To take in consideration:
The Kernel in the ROM has the frequencies that supports, most of the ROM comes with a top frequencies of 1782000. The SKZ kernel allows for a maximum frequency of 1890000.
The HP Touchpad where made with different suppliers of components. Due to this differences not all supports the same maximum frequencies. Very few can work under 1890000 or 18360000. But you can get lucky and have one. You should know and test the maximum speed that it will take, you can do that with Kernels apps before making modifications to the Boot Image, also the minimum frequencies are important as well.
The advantages of creating your own personal Maximum Speed Boot Image:
1 You will get faster boot time as the CPUs are set to work after the system starts the booting process and do not have to wait until the GUI starts and the Kernel app applies the settings.
2. Keep your ROM secure, no ROOT and no Super User, use it as is.
3. Less apps to install to take space and waste of Memory. Kernel apps and Super User have background services that are all time running just to give you the extra speed. Other apps can get the extra Ram for more processing.
4. There is more benefits of running the device at a higher frequency with no extra processing power, than have multiple apps to fine tune your CPU and governors but use resources.

It may be copied wrong. It should be: cpio --create -–format=’newc’ (not one dash but two, i.e. not -create, -format, but --create, --format)

The working path shows: [email protected]:/mnt/g/devices/tenderloin/hpboot$
I am not a Linux guru, but it look the boot.img is on the root of the tablet and not the PC.
The commands will only work properly if the directory is created in the root of the PC no where else.
((correction))
Yes, you are correct, is something about pasting a double dash that it turns into a hyphen (single dash). When editing the post it shows as intended, double dash. When publish, shows as a single dash, unless the font size is change on here and type again.
How I did it:
Enter the command in ubuntu terminal ( worked ) then copy and paste into LibreOffice Writer.
Write the guide, then copy and paste into the forum, to avoid any mistakes.
Then surprise ! a double dash is change to a hyphen and I am not even aware of it..!
Thanks for correcting!

I thought that, too, but there wouldn't be enough room for the dd command to work, and the error message wouldn't have been a cpio error.

The problem was on the formatting on my post. When I paste the guide for some reason it shows as a hyphen instead of a double dash.
I corrected the error. This is how it should be, also should work in the windows10 linux subsystem.

Thanks a million!

My apologies, you did everything right. The error was in the command I posted which is now corrected.
This is how it happen:
I created the commands in ubuntu text editor, then wrote the instructions in LibreOffice Writer, then copy and paste everything to this forum. Then the apostrophe character got changed and that is why the command was not working.
I tested the commands one by one and I was able to finish the process, you should be able to do it also. This is a learning process and I thank you for trying it and finding out the errors.
Redo everything again as I also corrected the changes for the CPU speed.
