Kifno's HeroC Universal Scripts v2.0.1
PLEASE READ THE ENTIRE FIRST POST BEFORE POSTING
THE CREDITING/PERMISSION ISSUE IS DONE AND OVER WITH EVER SINCE THE V1.x THREAD SO PLEASE NO MORE POST ABOUT THAT, OR YOU WILL BE REPORTED TO A MOD! ALSO I DID NOT JUST COMPILE A BUNCH OF MODS TOGETHER! IF YOU READ THE CREDITS YOU'LL SEE I ASKED TO USE THEIR IDEAS AND I IMPROVED THEM AND INCLUDED THEM ALONGSIDE MY WORK! SO PLEASE NO POST ABOUT I HAVEN'T DONE ANYTHING BECAUSE IT IS OFFENSIVE TO ME WHEN I KNOW I HAVE DONE EVERYTHING IN THIS SCRIPT FOR OUR HEROES, FROM MY CUSTOM VALUES TO THE IMPROVEMENTS OF OTHERS IDEAS OF WHICH I HAVE CREDITED AND GOT PERMISSION FROM AND SUBMITTED MY IMPROVED VERSION TO.
Thanks

My Explanation for the tweaks/scripts
Code:
Yes these are the tweaks I apply. They are what I think are the best
values for the file(s). Now I'll go into detail as to what each file is and why I set
a new value for it. If you don't like my opinion as to why my new value is
better please explain in a positive manner why you think so or just well...
then, no offense but just keep it to yourself. If you can't say anything
that is constructive POSITIVE critism without using language that could lead to
an argument/provakative language then please don't post here. Now on to the
explanations.
[B]Kernel Tweaks:[/B]
This specifies a period of time that the kernel gives a process that is holding a
file lease. After it has sent a signal to that process notifying, it that another
process is waiting to pen the file. In simpler terms this means that the kernel
has given the process a set amount of time it can hold a file after another
process has notifying it that it wants the file. The deafult had the time higher. I
set it lower. Although it doesn't make much of a difference, ever millionth of a
second counts :D
[CODE]/proc/sys/fs/lease-break-time
This enables cfq compatibility with older kernel models. This results in better
performance, for example more smoothness in apps and the launcher
Code:
/proc/sys/kernel/sched_compat_yield
This value has to correspond with the file-max value so this is raised according
to the value of the file-max. Why did I raise the file-max? Keep reading silly
Code:
/proc/sys/kernel/ngroup_max
Disables some annoying cfs scheduler feature (which is why I don't use the cfs
scheduler in my tweak, I use the noop scheduler) whic increase the UI's
performace just a bit.
Code:
/proc/sys/kernel/sched_features
Sets the maximum number of file-handles that the android kernel will put aside
for other use, share, or put in memory for other use. Usually increasing this
value is a good thing compared to the default value. Which in our case, it was.
If our kernels had an inode file we'd want the value of that to be 2-3 times as
much as the file max. Its a good tweaking rule I thought I'd let you know just
in case you're on linux
Code:
/proc/sys/fs/file-max
This is the max percentage of active processes that can be filled with dirty
pages before the pdflush begins writing them This MAY OR MAY NOT be the
default value for most kernels, but just in case it isn't I set it anyway. Why?
Becuase I want to make sure that if the dirty pages is about 19MB - 40MB of
our RAM, that pdflush begins writing
Code:
/proc/sys/vm/dirty_background_ratio
How agressively memory is "swapped" between disk and swap space.
Code:
/proc/sys/vm/swappiness
Lowering this is a good thing if on a system with slow I/O speeds between the
disk. But if this is lowered too much the I/O will get "constapated" and just
slow the phone down.
Code:
/proc/sys/vm/dirty_expire_centisecs
Doesn't do much but messing with the pdflush's timing of things. Little improvement but everything adds up
Code:
/proc/sys/vm/dirty_writeback_centisecs
Management of the phone's processes by setting a max amount of memory the
phone allows for dirty pages before stopping the processes writing.
Code:
/proc/sys/vm/dirty_ratio
Sets kernel priority for getting/releasing inodes and dentry cache files.
Higher = getting inodes and dentry cache files back more quickly
Lower = releasing inodes and dentry cache files a bit more quickly
Code:
/proc/sys/vm/vfs_cache_pressure
Changes the govenor depending on screen state
Code:
$*GOV
Changed timeslice lenght for better performance when using the phone, and
bettery battery when you aren't using the phone (screen off).
Code:
/proc/sys/kernel/sched_latency_ns
/proc/sys/kernel/sched_min_granularity_ns
/proc/sys/kernel/sched_wakeup_granularity_ns
Cpu frequencies. Pretty simple to explain
Code:
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
Amount of time before the interactive governor decides to change the cpu
speed.
Code:
/sys/devices/system/cpu/cpu0/cpufreq/interactive/min_sample_time
This is how often the kernel changes the frequency.
Code:
/sys/devices/system/cpu/cpu0/cpufreq/conservative/sampling_rate
This is the max rate at which the kernel can change frequencies.
Code:
/sys/devices/system/cpu/cpu0/cpufreq/conservative/sampling_rate_max
Thi is teh min rate at which the kernel can change frequencies.
Code:
/sys/devices/system/cpu/cpu0/cpufreq/conservative/sampling_rate_min
Average CPU usage from kernel's sampling rates which help it determine
wheather or not it should increase the CPU frequency.
Code:
/sys/devices/system/cpu/cpu0/cpufreq/conservative/up_threshold
This is what I use to find the battery percentage for the battery percentage
profile.
Code:
$capacity
This is what I use to find the temperature for the temperature profile.
Code:
$temp
Determines if phone is sleep or awake for screen state profile
Code:
$sleeping/$awake
This is the amount of power that was given towards wifi. I just upped the
amount a bit BETTER WIFI WOOHOO
Code:
/sys/module/acpuclock_arm11/parameters/pwrc_khz
/sys/module/acpuclock_arm11/parameters/wfi_khz
I/O Scheduler Tweaks:
IMO the noop scheduler is better for our read and write speeds. Simple as that.
And what more than a better scheduler for read and write speeds to go along
with the sd card speed tweaks?
Code:
echo noop > /sys/block/*/queue/scheduler
Set so that the phone's process, ram, or any other request won't get out of
order. This improves the performance because it helps our internal drive and
extral drive (if using apps2sd or data2ext or data2sd). How think of it as
organizing the request a little bit better than the default value This is more
of a being safe thing in fact, but also a little extra performance didn't hurt
anyone did it?
Code:
/sys/block/mmcblk0/queue/nr_requests
Network Tweaks:
These change the DNS server to 0.0.0.0 which in fact helped my mobile data
speeds go up by about 50-100kbps This DNS server was better than
google's or opendns (but I've always had problems with opendns). Though
google's dns server came close to being the better of the three this DNS server
was the best after being tested many times
Code:
nameserver 0.0.0.0 /etc/resolv.conf
The following are the combination of strings and values that I played with in the
beginning days of this tweak so configure our network speeds. It took about 6
hours of testing to come up with the best combination for the heroc And like
I've asked and I've said about at least 20x when asked, exactly how is our
CDMA network affected by these values when they aren't even meant for it?
They just do, now shh and enjoy your better 3G speeds But seriously ask
someone in the networking field or someone who works for sprint but is into
rooting androids (so you won't get into trouble because of hacking their data
tower speeds they give out to our herocs ). I did and it has something to do
data towers, I can't explain exactly how because once I heard that I was so
excited I just stopped listening as well
Code:
ro.ril.hsxpa=2
ro.ril.gprsclass=8
ro.ril.hep=1
ro.ril.hsdpa.category=24
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=3
wifi.supplicant_scan_interval=20
How frequently the keepalive probes are sent out is determined by tcp_keepalive_intvl This is value is dependent upon tcp_keepalive_probes as well, which determines how many probes are sent out. This determines the time not to kill the connection. I lowered this value so connections will be killed faster.
Code:
tcp_keepalive_intvl
tcp_keepalive_probes
Time to hold sockets, which I lowered.
Code:
tcp_fin_timeout
Socket receive buffer. Increased to increase sockets received from network.
Code:
rmem_default
Socket send buffer. Increased to increase sockets sent to the network.
Code:
wmem_default
Maximum socket receive buffer. Increased to increase the total amount of sockets we can receive from the network.
Code:
rmem_max
Maximum socket send buffer. Increased to increase the total amount of sockets we can send to the network.
Code:
wmem_max
Memory Tweaks:
This is the tweak I used to configure our internal task killer. I had to experiment
with this a lot becaue certain values made music playback very choppy when
the screen was in sleep mode. But at last these are the values I came up with
to keep our free ram high while not interfering with everyday usage too much
Code:
echo "3072,6144,9216,21000,23000,25000" > /sys/module/lowmemorykiller/parameters/minfree
SD Card Tweaks:
This is the cache of the sd card. This was set to 128 so I bumped it up to 1024. Other values may be better for your phone and it's sd card but this is the
most compatible across the board. Still a performance increase but just not the
optimal value. Why? Because all heros are different as well as that plust the sd
card everyone is using
Code:
read_ahead_kb
[/CODE]
Requirements:
- Rooted HTC Hero CDMA
- Kernel w/ Interactive, Smartass, Conservative, Powersave, Ondemand, and Performace Governors (Grab deca kernel and compile from source if not using cyanogenmod based roms, or use sobe's kernel)

- adjustments to kifCPU so that there will be longer battery life :D
- added a removal and backup script
Donations
I want everyone who is has ever donated, or has thought of donating me or anyone else to know this. XDA is a place for everyone to learn, teach, and share their work and new findings for android. Donations are not a right on XDA they are a privilege. Donations were allowed for XDA members to give and receive as a way for someone who really appreciates the original poster's work and is a way for the donor to show their thanks by doing more than pressing the thanks button. This is something that the original poster should appreciate and follow up with a PM as a thanks for their thanks, and use that as a notification, that they should keep up the good work and they're doing good things for XDA. Again recieving donations is not a right it is a privilege, that the original poster shouldn't abuse by asking for donations but instead appreciate when recieved. Asking for donations is not right and it is looked down upon on XDA because it goes against the meaning of what XDA is all about. This is something I want everyone to understand before even thinking of donating to me or anyone else or when given a donation. Don't donate because the original poster comes off as asking for money, instead if you choose to donate, donate out of showing more appreciation for another's work and as more of a way to show that you care for their work. I want everyone to understand that.

Okay gonna take it for a spin and see how it works. But I have a??? Does this mod preset the max/min cpu speed??? I use jm's kernel @ 710 max 691 min. But at work or when I'm in an area that has poor reception I bump it up to 768min 806 max. Am I able to still do this and use this tweak effectively??? Also does the removal zip from your prior tweak remove this?? Also to use the battery tweaks must I do the whole calibrate thing??? The reason I ask is I use the gf's data2ext mod and letting the battery discharge is a no go.

No it doesn't remove this I need to make a removal .zip asap. But You can just take the 768mhz zip and upzip it and change the cpu values in the /system/bin/kifCPU.sh file
just look for the the lines that effect the cpu speeds. If you don't know which ones do, then read my explanation for my tweaks
OH YEAH EVERYONE I ADDED MY EXPLANATION FOR TWEAKS If I am wrong about anything please, tell me asap so I can update it so people don't learn false information.
Glad to be on a fresh start with this
I'm gonna be all over this. Haha.
Please post feedback as to hours of battery life increase based on your normal usage and which build worked for you rom. Please post your rom and kernel you're using as well. and any other things you'd like for me to know as well. Thanks
flashing on aospCmod now (right after this nandroid finishes)
Haha. Outstanding!
Rom: CyanogenMod 7.0.2
Kif's Universal Script: Latency 768
Kernel: Sobe's AP5
Battery: Will post feed back when I get off work.
Network speed: Outstanding on my phone!
Keyboard response: before kid's tweak, laggy After kif's tweak, VERY! responsive.
UI: Speedy!
Haha. Feels like I just bought a new phone.
I can't wait to test this out on Rock Steady when I get home! Honestly I flash this on work hours. Ha. Yea I'm a flash freak like everyone else. I should just say I'm sick *cough cough* ha.
Outstanding work bro!
Will post more feedbacks when I get home.
Take care and God Bless.
I'm using one of Zen's kernels (710MHz)on NfiniteFX ROM. Can I use this? I'm not sure Zen's kernels have the governors you mention. Where can I get such a kernel, remembering that I am running Sense. I've read Zen kernels are usually best for Sense.
Thanks!
so far so good installed fine
downloads 35-50% faster on average on a few trials via 3g.
In regard to your explanation:
Code:
/sys/block/mmcblk1/queue/nr_requests
As stated previously in the old thread, this file has never and will never exist on the hero, because we only have one SD device.
This DNS server [0.0.0.0] was better than
google's or opendns (but I've always had problems with opendns)
Click to expand...
Click to collapse
0.0.0.0 is NOT a DNS. All this value does is force the phone to use whichever DNS the network specifies (which it may or may not be doing anyway).
Code:
ro.ril.hsxpa=2
ro.ril.gprsclass=8
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=24
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=3
You said to "ask someone in the networking field" about these values. Someone from the "networking field" (dhero) already chimed in (as did several other people) and told you that some of these lines don't even do anything. The only thing here that's probably making a difference in network speeds is the bitmask value (which is just setting all bits to 1, negating what they actually do).
For instance, I can tell you 100%, for a fact, that the "ro.ril.enable.dtm" line does nothing on the hero, because the entire point of this line is to enable simultaneous use of voice/data on GSM networks. CDMA networks have never been able to do this, and that's not something you can change
The line "ro.ril.enable.a53" also does absolutely nothing on our phones. A5/3 is an encryption algorithm, used on GSM networks. It has no use in CDMA devices, and was actually broken by hackers in recent history.
I've love to see some real documentation of how setting these values really makes a difference. The facts of speed tests are that (1) they are only testing your "burst" speeds which means they don't really answer many questions about long-term performance and that (2) they can vary wildly in the same time frame. I know that I have personally always had better EV-DO speeds than your scripts supposedly provide (sustained average 1.5-2mb/s downstream), and that all depends on signal range and nearby devices.
Right now I'm working on actually reverse-engineering the HTC RIL library to see what these values REALLY change. As far as I can tell, some of them never actually make a difference on the CDMA Hero and are just left over from the GSM Hero and other devices. They are read in from the prop file, but the variables which contain them aren't referenced by the CDMA code paths.
Code:
windowsmgr.max_events_per_sec=60
As stated previously in the old thread, this value does nothing because that's already the default value in the source code.
Code:
keyguard.no_require_sim=true
As stated previously in the old thread, this is already set in the build props.
Code:
debug.sf.hw=1
As stated previously in the old thread (and backed up by PROVIDING THE SOURCE CODE), this line does nothing because it's the equivalent of not specifying it at all. This is why we removed it from the CM build a LONG time ago. The ONLY time this line would EVER make a difference is if someone had deliberately set it to 0 beforehand, and as far as I know, no ROM (including the stock one) has ever shipped with 0 set.
The DEFAULT behavior of SurfaceFlinger is to always use the GPU when possible. The ONLY reason the "debug.sf.hw" line exists is for troubleshooting/debugging, for example when booting the emulator.
------------------------------------------
In regard to my own exploration of the zips provided (for reference I used the no-latency 691 zip):
You have a typo in your code.
Code:
CHECK_NOOP=` cat /sys/block/mtdblock3/queue/scheduler
The tailing backtick is missing.
Why are you providing busybox in your zip? The version you provide (1.15) is outdated; a newer version is already in CM7 and other ROM images. And the folder you're copying it to (system/sbin) doesn't actually exist.
By overwriting the init.local.rc script instead of appending your code to it, you are effectively breaking compcache in CM.
Your CPU profiles contain multiple infinite loops. This is bad practice. Your loops don't contain ANY sleep calls as far as I can tell, which means they run indefinitely, sucking up CPU cycles and battery. Your script should be sleeping on an interval.
The functions called by your infinite loop themselves contain infinite loops, which means that (as far as I can tell) they will never return and charging source changes will never be detected. Am I reading this wrong? Does this really work?
Blah blah blah..
Your scripts are working fine on my phone and others even though you've missed a few things here and there. The main thing is that your trying and trying leads to something even better. Looking forward to seeing v2.x and further.
I feel like I am on a creepy merry-go-round.....
Yet again kifno, when you could be an asset to the community simply by giving proper credits originally and saying that you used others work and made it better, you take all or most of the credit for yourself. If you want to help the community, do so by following the rules and common sense. FYI you cant "improve" brainmasters sd tweak because ALL it does is change the read_ahead_kb in sys/devices/virtual/bdi/179:0/read_ahead_kb. Now here's some links that users/mods/kifno would do well to pay attention to the dates of, these are also the only ones that I personally have reviewed recently, I would bet there are more:

Quite obviously this is not kifno's "original" work or ideas, or even code. After all it was recently noted in here that there is code for GSM devices. Why would that be in a script for a CDMA phone, unless of course the code was kanged. I just wish that if work was to be shared, it ought to be done so properly and not with this "MY WORK THIS TIME I SWEAR SILLY" bull.
I sent kifno a PM earlier tonight about this VERY thread when the OP only had credited uncorrupted. I told him to fix the lies about "all mine" and he did somewhat, but not fully as you all can see. My point is that this kind of action on my part SHOULD be unnecessary, but it seems to continue to be in ALL the threads kifno makes. Users, I know lots of this works but that's not the point. It is taken, and unabashedly handed out as original work, which it is not. That is why I continue to post relevant info when it it obvious. It is NOT to incite war, only to pay respect to the actual devs who created these works, which kifno does not seem to want to do.
I'm Pretty sure that the definition of kanging is taking others work without askance or credit - which is what this is. It's actually OK and encouraged to use others work in this community, that way we all get better tweaks and a better knowledge and a better user experience. BUT this is only OK if done following forum rules - which stem from mutual respect and community enrichment.
I am convinced the response will be "BUT BUT I DIDN'T COPY, I MADE THESE MYSELF", to which my response would be "yeah right".
Have a beautiful night/day ladies and gents. I have said my piece...
Let's try to stick to constructive criticism and not resort to personal attacks. It's killing the forum.

Do you use kifnos sense rom or espresso? I flashed the latency 768 tweak on his espresso 2.1 rom and everythings running flawlessly. I flashed the tweak on a full battery so I'll be back when the phone dies to report my battery life and performance.

Hmp I know what I'll do to fix m y nr_request tweak then I'll add it to the loop that checks for all values in the mmc* blocks Checked it and it already is I need to edit my reasons for the tweaks lol. So no worries this value is only changed in all mmc blocks that exsist.

0.0.0.0 is NOT a DNS. All this value does is force the phone to use whichever DNS the network specifies (which it may or may not be doing anyway).
Code:
ro.ril.hsxpa=2
ro.ril.gprsclass=8
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=24
ro.ril.enable.a53=1

ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=3
You said to "ask someone in the networking field" about these values. Someone from the "networking field" (dhero) already chimed in (as did several other people) and told you that some of these lines don't even do anything. The only thing here that's probably making a difference in network speeds is the bitmask value (which is just setting all bits to 1, negating what they actually do).
For instance, I can tell you 100%, for a fact, that the "ro.ril.enable.dtm" line does nothing on the hero, because the entire point of this line is to enable simultaneous use of voice/data on GSM networks. CDMA networks have never been able to do this, and that's not something you can change.
The line "ro.ril.enable.a53" also does absolutely nothing on our phones. A5/3 is an encryption algorithm, used on GSM networks. It has no use in CDMA devices, and was actually broken by hackers in recent history.

Oh wee thanks jason The lines you said to remove, and a few more lines have been removed from the network tweak, for next release, because only a few are making the real difference which I have tested.
jasonmaloney said:
I've love to see some real documentation of how setting these values really makes a difference. The facts of speed tests are that (1) they are only testing your "burst" speeds which means they don't really answer many questions about long-term performance and that (2) they can vary wildly in the same time frame. I know that I have personally always had better EV-DO speeds than your scripts supposedly provide (sustained average 1.5-2mb/s downstream), and that all depends on signal range and nearby devices.
Right now I'm working on actually reverse-engineering the HTC RIL library to see what these values REALLY change. As far as I can tell, some of them never actually make a difference on the CDMA Hero and are just left over from the GSM Hero and other devices. They are read in from the prop file, but the variables which contain them aren't referenced by the CDMA code paths.

If you could figure out exactly what they change (as far as I know its just general speed) that would be better for the first post's explanation of them. I'm going based of the fact that when I changed a few of the strings values, it slowed the network down, and certain values speed it up.
jasonmaloney said:
Code:
windowsmgr.max_events_per_sec=60
As stated previously in the old thread, this value does nothing because that's already the default value in the source code.
Code:
keyguard.no_require_sim=true
As stated previously in the old thread, this is already set in the build props.

Code:
debug.sf.hw=1
As stated previously in the old thread (and backed up by PROVIDING THE SOURCE CODE), this line does nothing because it's the equivalent of not specifying it at all. This is why we removed it from the CM build a LONG time ago. The ONLY time this line would EVER make a difference is if someone had deliberately set it to 0 beforehand, and as far as I know, no ROM (including the stock one) has ever shipped with 0 set.
The DEFAULT behavior of SurfaceFlinger is to always use the GPU when possible. The ONLY reason the "debug.sf.hw" line exists is for troubleshooting/debugging, for example when booting the emulator.

This is one that wasn't removed last night but will be I didn't know that it wasn't set to 0 because it wasn't specified in any roms I looked at. Thanks for that info

From what uncorrupted told me, in a way it is better than the busybox in most roms. I'll ask him about it, but until he provides reasons why, I'll remove it.

Your CPU profiles contain multiple infinite loops. This is bad practice. Your loops don't contain ANY sleep calls as far as I can tell, which means they run indefinitely, sucking up CPU cycles and battery. Your script should be sleeping on an interval.

I'll have it sleep every second or so because I doubt anyone is running their phone straight for hours and hours without letting it sleep. So adding a sleep interval will help with the should help with the battery life portion of this tweak as well
I had a sleep interval back in the v1.x series which helped the battery life, in my other infinite scripts, I need to add that again

The functions called by your infinite loop themselves contain infinite loops, which means that (as far as I can tell) they will never return and charging source changes will never be detected. Am I reading this wrong? Does this really work?

Oh yes Do you know what a until loop is? It basically saying the temperature drops it will cap the cpu speed. Once the temperature isn't high anymore then it uncaps the cpu speed again So this is to keep your phone from getting too hot, I know my phone does Also since the cpu is being capped this would result in the battery temperature going down and therefore once the temp is lowered it returns to the battery charging source changes. So yes it does work

Yet again kifno, when you could be an asset to the community simply by giving proper credits originally and saying that you used others work and made it better, you take all or most of the credit for yourself. If you want to help the community, do so by following the rules and common sense. FYI you cant "improve" brainmasters sd tweak because ALL it does is change the read_ahead_kb in sys/devices/virtual/bdi/179:0/read_ahead_kb.

I did improve his tweak, so there you are wrong sir. I will be sending him a message about if he changed the value for all the bdi's sub-directories read_ahead_kb he would in fact improve his sd tweak. He sets it for just the 179:0 but when I changed it to set it for changing all the bdi's sub-directories read_ahead_kb my sd card performance was much better, than just his tweak which just made it better.

The one's who I ORIGIANALLY got the ideas from are credited. Anyone who is not credited I did not get any ideas from. If a person isn't allowed to use their knowledge of linux operating system's files and how they tweak linux and use them on android then that just isn't right. I've been on linux for years and you're saying that the tweaks I used for my linux system I can't change the values and use on the heroc, come on now. That isn't fair.
il Duce said:
Quite obviously this is not kifno's "original" work or ideas, or even code. After all it was recently noted in here that there is code for GSM devices. Why would that be in a script for a CDMA phone, unless of course the code was kanged. I just wish that if work was to be shared, it ought to be done so properly and not with this "MY WORK THIS TIME I SWEAR SILLY" bull.
I sent kifno a PM earlier tonight about this VERY thread when the OP only had credited uncorrupted. I told him to fix the lies about "all mine" and he did somewhat, but not fully as you all can see. My point is that this kind of action on my part SHOULD be unnecessary, but it seems to continue to be in ALL the threads kifno makes. Users, I know lots of this works but that's not the point. It is taken, and unabashedly handed out as original work, which it is not. That is why I continue to post relevant info when it it obvious. It is NOT to incite war, only to pay respect to the actual devs who created these works, which kifno does not seem to want to do.
I'm Pretty sure that the definition of kanging is taking others work without askance or credit - which is what this is. It's actually OK and encouraged to use others work in this community, that way we all get better tweaks and a better knowledge and a better user experience. BUT this is only OK if done following forum rules - which stem from mutual respect and community enrichment.
I am convinced the response will be "BUT BUT I DIDN'T COPY, I MADE THESE MYSELF", to which my response would be "yeah right".

The response you are "convinced" will be, is not the response I am giving you. The people whose ideas I were using and made better were back from the 0.x series (which is long ago). Also as for the code not even being mine? THE MAJORITY OF IT IS MINE. I used the screen state idea and built off of it to make a full out, cpu/batter tweak utility replacement. My next step is to make a menu for the users to change those values themselves. The users whose ideas I have used AND IMPROVED ON, have been credited as we talked about, I just had to backtrack who I really got the ideas from and not others who used their ideas as well as myself. Everything else I have done, and came up with myself. Believe it or not. Use linux for a few years on a sucky laptop and I bet you'll be wanted to tweak it, too. Which is how I learned so much about linux's files, which I quickly found android to be almost like a "portable linux" operating system One of the reasons I got the phone.

Well sadly i don't have an answer for that question yet...
I'm trying to think of a way to put KSM to the test on my android device.
As far as i understand it is possible that the kernel actually causes high CPU usage trying to map and unmap memory pages over and over again.
This issue is known for linux and other virtual machines so it is possible that the Same effect will be on the android vm
Testings that i found are not relevant to android.
For example:
The result is a dramatic decrease in memory usage in virtualization environments. In a virtualization server, Red Hat found that thanks to KSM, KVM can run as many as 52 Windows XP VMs with 1 GB of RAM each on a server with just 16 GB of RAM. Because KSM works transparently to userspace apps, it can be adopted very easily, and provides huge memory savings for free to current production systems. It was originally developed for use with KVM, but it can be also used with any other virtualization system - or even in non virtualization workloads, for example applications that for some reason have several processes using lots of memory that could be shared.
Click to expand...
Click to collapse
http://kernelnewbies.org/Linux_2_6_32
What i would really want to know is what would happen if each of these VMs Would run a different application/game/audio/graphics software at the same time ? or what if the same vm will run many different apps ? and also to compare cpu usage with and without KSM
Guess i'll need a tool for that. something like 'iostat' but for memory diagnostic and another tool to see a per process CPU usage but 'top' is not good enough for that.
Any way, the best test should present clear results with precised data.
I'll keep looking for legit way to put it to the test.
If you can think of a way to test KSM with android, please let me know.
This is a technique that relates mostly to processes like virtualisation. For example, when you load 5 windows XP VMs, you'll have a good 10 - 20 services that are practically the same in memory in each VM. Instead of each service using 10mb (ie, 10mb x 5 = 50mb), you only need say 15 or 20mb using KSM. If you use different applications, it is very unlikely that anything would be saved FOR THAT APPLICATION. However, the main elements of a Windows XP System would still be there (drivers, explorer, firewall, logon, search and so on). Means little in one setup, but when you have several VMs it is shown to be a huge advantage. As we know a simple XP install can use 500mb of RAM actively, and this is fairly uniform across instals.
With android, i don't know if there are specific RAM savings to be had. Don't know enough about the inner workings and the sandbox android puts its apps in or how apps interact with system services. Sadly, i can't think of a good way to test it out either, but i'll be keeping an eye on this topic for someone (much) more knowledgeable to come along.

KSM does not improve performance on Android just like that - all enabling KSM does, is enable SUPPORT for the Feature but Applications would have to make use of the feature, which they don't.
You can easily verify this like that :
echo 1 > /sys/kernel/mm/ksm/run
<wait and/or run the Applications of your choice>
cat /sys/kernel/mm/ksm/pages_sharing
IF the above shows a value > 0 then you are making use of KSM else it's just available, without anyone using the feature.
Here's an interesting Article that gives a little more insight :
http://www.linux-kvm.com/content/using-ksm-kernel-samepage-merging-kvm
By the way, the same is true for ZCACHE. If you really want to make better use of your Memory (RAM) then using ZRAM as a Swapdevice does work (and may often make sense, too).
That all said : There appear to be efforts to make use of KSM http://forum.xda-developers.com/showthread.php?t=1464758 - so things may well change ...
any update on this...?
Hi
Before I mean that applications and tweaks that will give them are the ones I've used, tested and have worked for me, so if you have that you know could be so kind as to comment as you lack have managed to control the use of RAM.
I also want to say sorry if my English is bad, I had to use the Google translator on the one hand and on the other my little knowledge in English, I'm sorry.
Not if you have noticed but in the Custom Roms of our device we overuse of RAM, this becomes more noticeable even Roms based on Lollipop, as can be CyanogenMod 12 where we can see that sometimes bubbles Messenger chat can be closed or the music is turned off, so I write this guide to explain how to control this use with some applications that truth to me I have worked.
-Apps:
The truth use applications to control the use of RAM is very embarrassing, since we are no longer in a device with 180MB of RAM, and have to use Tweaks or applications that optimize this, for some use some Tweak or application on this device is something good to optimize it a bit more, but we think 1GB of RAM and a 1.2 Ghz processor with 4 core.
To control the use of RAM I recommend...
Root Booster(FULL VERSION):
https://play.google.com/store/apps/details?id=com.ram.memory.booster.cpu.saver
The truth is that this application achieving control the use of RAM on my device, but I had to buy the full version, you can use the mode solves this problem, in short, once you buy the application must be enabled mode more stability and activate (Required root to use this application, it is a bit obvious that the application is called root Booster).
AutoKiller:
Before knowing Root Booster using this application but really saw that I closed many processes necessary but the truth if I won a big improvement in the management of RAM, the truth if you run install I recommend you select the Ultimate mode.
-Tweaks:
Truth does not recommend it Tweaks init.d but the truth if they help as much as elsewhere in scrolling speed or other you run.
L-Speed:
http://forum.xda-developers.com/android/software-hacking/tweak-l-speed-v1-0-02-02-2015-t3020138
This Tweak me if I worked well to improve the speed of scrolling and a little more open applications, RAM usage but saw no improvement truth in one or another section if that worked.
Now, this is the only tweak I can recommend for this device.
-Things not recommend:
Do not mix Tweaks:
Many would say that mixing Tweaks will gain greater speed, but not really. In some cases this may cause system instability, causing not work normally, can cause terrible lags or even a brick, do not think for mixing Tweaks will gain greater speed, if your system already works well with you Tweak to mix with more.
Do not mix apps:
I say almost the same as in the previous tip, if your device and works well with an application to modify that, the truth if mixed apps can cause applications to close or in some cases are playing something and that game middle parting closure.
Well, that's all I can tell you, as I said at the beginning of the post if you have any Tweak or application that worked them to control this might share? would help users much more control this big problem, I hope you enjoyed this post and wish them well controlling this great use of RAM in their devices,
Greetings.
XDA Kernel and ROM flashing beginners guide.
If you are reading this, you’ve found your way to the famous XDA Forums. The place where developers and users contribute to the spirit of open source Android development.
If you already have TWRP setup and running and just look for the next ROM to flash, this guide isn’t for you. If you wonder what this TWRP thingy is or what exactly the three letters, R O M mean, that float around these forums all the time, then read on.
This paragraph is about the basic geek terminology, used by developers. ROM stands for read only memory, which basically is the system partition of your device, which can only be read, not written. In everyday usage scenarios, where you browse the web, download some apps, or chat und Telegram, you will never get in the situation, where you have to write on your /system partition. If you plan to get your hands on one of those amazing custom ROMs, that add battery life, performance and beauty of use to your OS experience, the ROM is the smartest way of accomplishing this goal.
What a custom recovery is used for:
This is where the recovery comes into play. The recovery partition is pre installed by the manufacturer of your device. It is used for OEM software updates, wiping your cache and dalvic or performing a factory reset. Enough functionality for the average Joe, but this is XDA developers. Things get interesting, once you unlock the full potential of your device. To do so, you’ll need a custom recovery. Team Win Recovery Project (TWRP) is most common these days. It is fully optimized for touch screen input and offers various features, that even come in handy, if you don’t want to modify your phones software. Nandroids for example.
This is where things start to become really interesting. There are various recognized XDA Developers like Francisco Franco or Flar2 who focus their efforts on bringing custom Kernels to their supported devices. What is a kernel? Do I even need it and why should I bother changing it?
To say this clearly, the kernel is the heart of your software. You might use your phone with a broken Bluetooth driver, without caring to much, without a kernel installed your device won’t be able to boot. So what does the kernel do, if it is so essential for a proper working phone? We can describe it as the bridge between hardware and software. That latest processor and the wickedly fast RAM won’t do anything without something telling it how to unleash it ‘s potential.
That’s where the kernel comes into play. You can imagine the kernel as a moderator between the hardware and the software of your system. An example: You touch the screen to launch your favorite game on your Droid. This game is really challenging your hardware, so the processor has to run on a high clock frequency, otherwise the game would take ages to load. The kernel detects your input and ramps up the frequency by it’s in input boost driver. This is often a pre configured value, that is used as soon as some (touch) input is detected, that’s why it is often called touchboost. OEMs choose a middle frequency offering a good balance between power consumption and performance.
For our gaming scenario this isn’t enough, we need the full potential of the CPU and the GPU should get busy rendering all those pixels as soon as possible. This task is accomplished by the kernel. It is balancing the system frequency based on the load of the system, but that’s just an easy to explain example of what a kernel does. The kernel is doing a lot more things on your device. How should the phone know, how much RAM it can give to that messaging application you open every each five minutes? Simple answer, it doesn’t the hardware of your phone is just silicon ready to do your work. You can compare it to a young guy doing an internship at a company. The guy has some potential, but he gets lost in a moment, if there is nobody showing him what to do. This is where the kernel comes into play again. It calculates which task requires which amount of memory and decides, which task should be kicked out of your recent access and memory and, which is there to stay. The messaging application I just mentioned a few lines back for example should remain in memory. You use it all the time, so it doesn’t make any sense to generate some unnecessary CPU load, which eats up your battery in the long run.
As you can see the kernel is more than a boring piece of code. It basically drives your phone, so you really want a stable kernel.
Which different kernel development approaches exist?
There are various recognized developers who focus on UX features. This means they take the official stock kernel (be it a OEM or let’s say the one made by Lineage) and they add their features on top. For example a fading notification LED or a backlight dimmer, that allows to lower the minimum screen brightness further than the stock kernel allows.
These features focus on adding userspace features on top, which don’t touch the core functionality of the kernel, like CPU scaling or RAM management. These kernels are chosen by users who want additional kernel functionality without leaving the stability of the stock ROM in favor of a custom ROM.
On the other hand their are developers and users who want bleeding edge functionality, which brings new stuff to the table, but is to new and not deemed stable enough to be used in the mainline OEM kernel. A good example for such a feature is f2fs support. F2fs is a file system developed by Samsung. It’s main focus is to suite flash storage (like the SD cards in our smartphones), in terms of write speeds it is significantly faster, than the established and rock stable standard ext4. But it comes with certain downsides for example a ROM won’t boot with a data partition formatted to f2fs if the kernel doesn’t have the required f2fs commits. A year back their also were some major issues with root, which made a lot of users switch back to the stable ext4. However if you want to squeeze the last bit of performance out of your phone, the kernel is the way to go.
Kernel tweaking: A custom kernel allows you to modify certain parameters, which aren’t accessible for the using an official kernel. Some developers ship with their own app, which is optimized to tweak their own kernel. This ensures maximum compatibility, one of the reasons why those kernels are so successful across all XDA sub forums. You don’t have to use a kernel managing app to modify your kernel configuration, you could also use an init.d script, but this requires further knowledge. No matter how advanced your knowledge is, it doesn’t get any easier than using an application to set up the configuration of your choice.
Kernel tweaking fills another guide and their is already a really good one, that you should check it out. Further links will be put at the end of this guide.
To root or not to root?
Another controversial topic is rooting. While a lot of OEMs try to prevent you from doing so by locking the bootloader, a lot of enthusiast swear on the power root access unleashes. Often android root is compared to administrator privileges under Windows. This is an illustrative explanation, but isn’t accurate. Root goes far beyond what Windows Admin rights allow. The main difference that jumps right into your eye: Microsoft allows Administrator access out of the box. Root is blocked by all OEMs, you have to enable it manually (by flashing a root solution of your choice. More about popular root solutions and their main advantages and disadvantages down below.
So what does root do? It gives you full control over your device. One of the main advantages is to gain write access to your system partition, which normally is read only. The power of root is defined by the knowledge of the user, the more you know, the more you can make out of it. For beginnners root apps like Titanium Backup, Adaway, Better Battery Stats or SD Maid are interesting. They utilize the potential of root for you without having to dig to deep into the topic. However root isn’t enabled by default for a reason. Most big custom ROMs, don’t ship with root out of the box anymore these days. Back in the day root basically just gave you more control, without any major disadvantages. This however changed with the introduction of Safety net by Google.
The company developing the OS we all love, is trying to make Android safer and they are pushing this approach forward these days. If you just flash SuperSu, Safetynet gets triggered which results in being unable to use apps which use Safetynet to verify the integrity of your system. Mainly banking apps, but also Snapchat for example or that stupid game, that generated all the hype in summer 2016. You got curious about root or came to this forum, to figure out how to root your phone? Then the next paragraph deserves your attention.
Most XDA users used SuperSU developed by XDA legend Chainfire during the last years. A while ago Magisk by XDA Recognized Developer and contributor Topjonwu. It became very popular, when Safetynet started to break certain Apps. It allows to hide root from safetynet, but it includes much more. One of the key features is mounting modules systemlessly to your boot partition, that way your /system stays untouched and removing a certain module, doesn’t require more than disabling it and rebooting. What about the disadvantages of magisk? It isn’t as compatible as SuperSU, since that root solution was the standard for years. All the developer arranged their work around SuperSU, but most famous root apps, have already adopted to Magisk, so you won’t run into issues unless you are using really outdated apps, which is never a good idea.
Which one to choose is a decision you can make. Both work flawless and it really comes down to personal preference.
Since nobody is willing to read through 50 pages, I’ll just thank you for your attention. This Guide is on going WIP, so if there is anything you’d like to see being added, feel free to let me know, but make sure to tag me, otherwise I might miss your message in the storm of ongoing notifications. Have a great day and keep flashing.
