Awesome.

I am really curious about something. Can i change the cpu settings by remounting /system and directly modifying the files in cpu0/cpufreq myself in a text editor? I can do this with an init.d script, but id rather do it directly. Since the ideal OCing and UVing settings are different for each cpu it would be great if i could simply set the ideal parameters for my cpu revision. If this is possible ill write up a tutorial describing the various parameters in cpu0/cpufreq and how to change them, then we can all simply find the ideal parameters for our specific cpu revision. You are too good at this to be wasting time tweaking cpu/gpu freq and voltage for all of us, there are no universally perfect cpu/gpu parameters, especially when OCing and UVing. Id rather see ppl do this themselves, so your time can be spent more productively. Force people to learn how to do it on their own lol. I wouldnt mind helping write up tutorials, i really enjoy writing, and teaching is the best way to learn.

---------- Post added at 02:11 PM ---------- Previous post was at 02:07 PM ----------

Im glad its working well for you, when OCing and UVing at a high level things get really finicky and are very device specific. Right now I am running 1.85Ghz cpu and 725Mhz/1375mV gpu and everything is zippy, cool, and stable.
[Asus Transformer TF700] *justintime*:
For me the 1700mhz 750 gpu is working great.

The tablet is cool and everything is smooth as butter. Even in balanced mode Flipboard is browsing with no lag.

Did some gaming for an hour (MC4) browsing etc etc.....

THANKS Hunds its working great!!!

Cross Breeder Mod - frandom - improved random number generator, no entropy

Hey Hunds,

I have been using the latest version of Cross Breeder Mod 3.15.13 and have had amazing results. sdbags included the original version in the 2.3 kernel installer, which worked quite well, but it has been updated several times since that version and the latest is running incredibly well. I honestly cant beleive how fast web pages load, and it makes AdAway behave like AdBloccker for chrome desktop, i no longer get that annoying "webpage not available" garbage. The CB utilizes five strategies to reduce lag, however, the 5th can only be implemented by adding a module to the kernel, once the module is added and loaded, CB will automatically detect it and start using it. I was just wondering it you could see if it would be possible to add the module to your kernel so that we can get this tweak to work.

The mod links /dev/random and /dev/urandom to /dev/frandom and /dev/erandom. I did some background reading and this mod seems pretty legit, frandom seems like a more efficient random number generator that does not rely on entropy. If you could compile the module and upload the .ko file i could implement it myself, im pretty sure I just need to place it in dev/lib/modules and create an init.d script to load it at boot.

Here is original CB mod page, the mod i speak of is #5 - http://xdaforums.com/showthread.php?t=2113150

Here is a link to download the frandom module tarball and some background on why it was developed and how it works - http://billauer.co.il/frandom.html

Thanks,

Lucius

AW: [KERNEL][OC][STOCK/CROMI] Hundsbuah ★ 10.4.4.25 ★ v1.9 ★ dualboot

I dont think the gpu runs at 750 with 1300mV because 1300mV is for gpu freqs below 650mhz in the dvfs Table. 3d quadrant score is too low for 750mhz gpu

Try 1400mv for gpu 750mhz if score is higher

gpu voltage

Hello Hundsbuah, i have a init.d script to set the gpu voltage, but when i change the gpu frequency, the voltage returns to its default value (1450). Is this because of the kernel or because of trickster mod?
[Asus Transformer TF700] Thats OK:
Wow Hundsbuah!

Both new test versions 1700 and 1750 run very well on my tablet!

Re: [KERNEL][OC][STOCK/CROMI] Hundsbuah ★ 10.4.4.25 ★ v1.9 ★ dualboot

its on page 50 or 51. its not working so well though.

anyway, hundsbuah, I think something is wrong with the 0.8.1 installer you released. ive had to format internal storage twice because it just keeps messing it up. what I did was install 0.8.1 hundsbuah kernel install over my last rootfs image without backing it up. when it was done I tried to boot ubuntu and it gave me the lib/module nonexistant error. tried to boot it again and it went through this long list of rm: cant remove file _____ and it looks like it did that for the whole rootfs image. after that my internal stroage was inaccessable both when booting into android and in cwm. so I reformat emmc, boot into non data2sd, copied over the hundsbuahv2 installer with the rootfs.lzma and tried it again. did the same exact thing. that was last night so im going to reformat my internal storage again and I guess install ubuntu with the 0.8.0 installer until .8.1 works
[Asus Transformer TF700] lucius.zen:
We must have very similar cpus, Im running 1.9.3 at 750Mhz/1420mV and 1.85 Ghz with v2.1 of my voltage table. It is running smoother, is more stable, and has lower heat than v2.0 at 1.75 Ghz and 750Mhz/1420mV, which is kind of weird, my cpu prefers 1.85 to 1.75. I dont really care, my quadrant scores are 7400+ without data2SD, i havent gotten any reboots/ANRs, and my temp after benchmarking in performance mode is 42C.

Re: [KERNEL][OC][STOCK/CROMI] Hundsbuah ★ 10.4.4.25 ★ v1.9 ★ dualboot

what is this performance test you guys use?
[Asus Transformer TF700] lucius.zen:
Hey steveman,

I wrote a custom init.d script to set the voltage table, GPU frequency/voltage, and io scheduler that works on 1.9.3 and 2.0. I am at work right now but I am going to upload it when i am done with a quick guide on how to apply it and set the values. it is really easy to set up and will preserve settings at every reboot.

Plus, you also will no longer have to use any apps to set kernel tweaks at boot. A custom 5 line script tweaking the kernel at boot is better than having an app dig its fingers into the kernel at every boot. I disabled all my tweaks in AT and just use this little script instead, works much better.

Im also thinking of putting together a quick guide to writing init.d scripts, however, i will only do it if it is something ppl are interested in.

All the best,

Lucius
[Asus Transformer TF700] sbdags:
That would be really useful for a lot of people :good:
[Asus Transformer TF700] iamborba:
+1 I would prefer using a script over having to use a program. Would be very handy.
[Asus Transformer TF700] Hundsbuah:
sorry i for the late answers.

regarding the problem with the dualboot installer. i used the latest rabits git sync and the latest rabits installer script to create the dualboot installer. dont know where the problem is.

regarding the question about resetting the voltage:

if you apply new gpu speeds with the gpu oc interface (trickster mod does the same) follwing gpu volt settings are done:

if (gpu_freq <= 650) {
new_volt = 1350;
vde->dvfs->millivolts[i] = new_volt;
pr_info("NEW VOLTAGES < 600: %d\n", vde->dvfs->millivolts[i]);
}
if (gpu_freq > 650 && gpu_freq <= 700) {
new_volt = 1400;
vde->dvfs->millivolts[i] = new_volt;
pr_info("NEW VOLTAGES >= && <= 700: %d\n", vde->dvfs->millivolts[i]);
}
if (gpu_freq > 700) {
new_volt = 1450;
vde->dvfs->millivolts[i] = new_volt;
pr_info("NEW VOLTAGES > 700: %d\n", vde->dvfs->millivolts[i]);
}

for init.d scripts: you have to set the gpu speed and then you have to set the gpu voltage you want.

if i have time left today ill try to build the kernel module for the seeder.
[Asus Transformer TF700] steveman29:
Great thanks, it would help a lot.
[Asus Transformer TF700] Hundsbuah:
hm more easy as i thought :D

here is the module: http://www43.zippyshare.com/v/96077216/file.html

you can put it in /system/lib/modules/ and load it via terminal emulator:

su
insmod /system/lib/modules/frandom.ko

you can check it with:

lsmod

you should see something like this:

i think ill post the 1750mhz version for a stable version? i think the 1750mhz version is running fine and the heat is acceptable even for older cpu revisions - what do you think?

thanks for your help and sorry for some "bad" kernel releases in the past... :(

but with the help of the community we will make it :)
[Asus Transformer TF700] spidasense:
ok so the only way I could get the v2 dualboot installer to work is that when installing it, instead of just flashing the boot image, you have to install a whole new root image, make sure you backup the old one, let it finish installing, boot into android (dont boot ubuntu yet), open up a file manager, delete or rename the new rootfs image that was just installed and rename rootfs-old to rootfs. I havent tried just booting into the old root image from the bootimage but that is how I have gotten it to work.
[Asus Transformer TF700] steveman29:
Hundsbuah could you add touchdemand governor in a future version? I just tried it with my htc one x and i have zero lag while scrolling. Also will you consider overclocking LP core to 666MHz to save battery life?

I think the 1750 version would be great with the module added Hundsbuah.

No heat problems here with 1750.

No tweaking after boot would be great also!

Thanx again!
[Asus Transformer TF700] lucius.zen:
Hey guys,

Will definitely write up a simple tutorial for writing init.d scripts and will upload mine so you have an example to work with. Right now my script sets the cpu voltage table, gpu frequency and voltage, and the scheduler, which is all i need, but it would be easy to add a line or two tweak any cpu/gpu/scheduler parameter. Ill make sure i include a section explaining what files contain each cpu parameter, and where to find them, so that you can set whatever it is that you want.

Unfortunately i cant do this tonight bc i have a paper due tmrw, but ill definitely get on it tmrw afternoon and have it up asap.

Best,

Lucius

---------- Post added at 02:40 AM ---------- Previous post was at 02:24 AM ----------

Awesome i cant wait to see how this module works, im glad it wasnt very difficult, thanks a lot for the quick upload.

I definitely think the first stable release should be 1750. although 1750 doesnt seem to run as well as 1850 on my cpu it definitely seems to be the most stable for the most number of people. For now stick with 1750, eventually id be nice to have 1800. since i started OCing ive always gotten the best results on 1800. However, in a perfect world we would have a kernel where we could set the max freq to w/e we want with an init.d script lol. There ultimately isnt a perfect setup for everyone. The holy grail is full customizability.

Dont worry about any bad releases, i use this kernel bc you take risks and push the hardware. your on that next level ****. I dont want my tablet to be great. I want my tablet to crush.

keep up the great work.

i am pretty sure it still runs at 750 , i think it just ignores the gpu_oc_volt settings if they don't follow the rules... my scores stay the same!

i have tested from 600 thru to 750 and slowly my nenamark scores come up to 48's ... but not 49's ;)

i have tried setting with ini file at boot and loads anything for voltage - ie 1000 at 750 but scores the same as 1450.

what scores are you getting with quadrant for 3D? i am lucky to get near 2500 with any setting! and usually if i get high 3d it is at the cost of my cpu score... if i get 17800 my 3d 2350/2400 ... if i get 17300 my 3d closer to 2500 ! ... i can consistently get 7400+

still luvn using 1 core though! my battery and temps luv it ! for everyday battery saving and my browser flies on battery saver...

ps- tests done with quadrant/nenamark/antutu/stability

ps- while you waiting for Zen's tidy ini scripts... these are my ones... just remove .txt and place in ini folder with rwxr_xr_x ...

[Asus Transformer TF700] buhohitr:
As long as they don't step over each others, you don't have to remove any.

90Hundsbuah - Kernel tweak

99CleanTweaks - Cromi tweaks

Seeder - Seeder app OR zzzcross_breeder (only use one or the other)

I believe the voltage control ini will be called 999voltage and can be added to what you already have.
[Asus Transformer TF700] Hundsbuah:
its recommended to name the init.d script files with two digits infront of the name because that descripes the order the init.d scripts are applied at boot.

from 00XXXXX to 99XXXXXXX

so you can make a new file 80ZZZZZZ for example and put it in the init.d folder

this will called after 79AAAA files and before 81BBBBB init script files. but all files in the init.d folder are executed at boot

2.0 data2sd version seems to be running fine. Any plans for a fixed dualboot version?
[Asus Transformer TF700] spidasense:
dualboot works, I explained how to do it previously but ill explain it better here. you have to delete the rootfs image that got messed up with v2 hundsbuah installer, do a fresh install of a brand new rootfs image with the REGULAR/ORIGINAL 0.8.1 dualboot installer, uncheck reboot system, close aroma installer, do ANOTHER dualboot install except this time use hundsbuah's 2.0 installer and when installing the rootfs image make sure you have the option selected to backup the previous image. After its done installing ( you can make it a 3gb partition cause you wont be using the hundsbuah installed rootfs image), at the duaboot menu, once you select linux, boot into rootfs-old.img and it should work. the newly installed rootfs.img wont work. you can delete it but I would suggest keeping it incase you flash a different kernel and then want to flash only the hundsbuah 2.0 bootimage again to get back into linux using rootfs-old.img again.

you can do that all without leaving cwm or twrp or rebooting and it will work.

Yeah the govs are all messed up. Powersave turns off 3 cores and peggs core0 at 51.

Also when i lower the max freq it still goes up to 1.5 or 1.75. Btw ive tried multiple programs.

Swithing to pegasusq locks the tablet up.

faster boots .... its the need 4 speed !

if anyone wants to boot up in "performance" mode ...

copy your cpu3.sh into your init.d folder and change first line...

to

#!/system/bin/sh

rename file to - 999zPerformance and set permissions to rwxr-x-r-x ...

note: the only reason i use 3 numbers is because every other mod uses 99! ( other than hundsbuah:good:)

Hey Hunds,

I want to start unloading unnecessary modules at boot. however, i can find very little info online about what each module does. Do you know of any good resources?

Its surprisingly difficult to find good android tutorials. There are lots of guides on rooting, unlocking, and flashing other peoples mods. however, there are very few resources for ppl who want to start doing their own modding or tweaking.
