[HTC One V] 1ceb0x:
I have some questions since I know very little about undervolting (never used it before tbh). I know these answers depends on my phone alone and my cpu, but here it goes:

1. What will happen if I undervolt my cpu too low? What simptom should I see? I need this to understand if it is a undervolting problem or anything else. My guess is that, my phone will start and reboot itself from the blue.

2. For a 1.7 ghz overclock, what is the undervolting step recommended?

3. If you overclock a bit too much, you need to undervolt, right? If I have 1.5 overclock and let's say 70 UV and I will overclock it to 1.7, I will need a lower or higher UV value than 70?

I'm sorry for asking these here, I am too lazy to get answers from the forums. Cheers people
[HTC One V] shubhamchamaria:
just do -5 from stock values. Too much undervolting can be dangerous
[HTC One V] maxwen:
Hi

Just like OC this is some kind of "trying whats possible"

Different devices may behave different depending on the HW

So start with a "reasonable" value and see if the device still

runs stable. Too much UV will behave like too high OC :)

I use a -100 for all frequencies since UV has become available

in Titanium kernel (max 1.5GHz kernel) and never had problems so far

To make UV "permanent" between reboots you can then

add it to a init.d script.

NO WIFI

BOOTED VirtousS4-A2 kernel back
[HTC One V] Adi_Pat:
Thanks, I will fix wifi in the next kernel :)
[HTC One V] shubhamchamaria:
The boot.IMG ain't the problem...the problem is that you didn't provide the modules specifically bcmdhd.ko with your kernel which is the WiFi module..
[HTC One V] Adi_Pat:
Yeah I know..!!!

I will load the module via init.rc and place the module in lib/modules in the ramdisk :)
[HTC One V] Adi_Pat:
Ok test this kernel, Wifi module is loaded at boot, so no WIFI issues.. plus I have made some more changes. Will experiment with Overclocking and will add Governers if this boots.

Tester Needed

Ok, so i have tried a particular method for undervolting one v, since i donot have the device,

i want users to test this part of the code :)

Link :- http://www.datafilehost.com/download-f49bd510.html

Please test the voltage part and check if the changes have taken place, by pressing back and opening voltage again, and checking if the Current Value for that particular Frequency step has changed or no,

Thanks :)

Thank me if this app works will or if i have helped you, Regards
[HTC One V] 1ceb0x:
Everytime I try to change the values, it says "value not in range". I tried with 100, 50, 20, nothing... I even tried with '-' and number. You have to make another interface because that's pretty buggy. For example if you try to write some values (for undervolting), the keyboard pops up and the blank field where you enter your desired values, stays under the keyboard and you are not able to see nothing when typing. I understand this is only an alpha build...
[HTC One V] s4shyam95:
Look, The Volting range for this kernel is 700mV to 1500mV, u cant enter 50 and stuff, enter a value between this range...

And i did not find any UI bug as u mentioned, that the keyboard overlaps it,, Please try again and lemme know,,

PN again:- u have to enter the voltage value u want to use ..
[HTC One V] 1ceb0x:
Working now. I didn't exited that specific screen. Confirm as working for 368 mhz - changed to 975 (I decided to make it 990 but the program changed it to 975. Is it intended?) instead of 1050.

But the bug with the keyboard still remains. I am on stock rom, rooted.
[HTC One V] s4shyam95:
I didnt get you, you changed value for a particular freq step,, and then exited that and went back to main menu ,, and then opened it again... and u didnt see the changed value?
[HTC One V] boland:
Nice Kernel :) I have overclocked to 1500 Mhz and I get the following results in Quadrant Standard.

Old (stock ROM):

CPU:2086, MEM:891, I/O:5245, 2D:288, 3D:1580

Totaal: 2038

New (MyOne v 2.1 ROM, Titanium Kernel @ 1500Mhz):

CPU: 3091, MEM:1195, I/O: 2306, 2D: 490, 3D: 1881

Total: 1793

I have sio as I/O scheduler, but how come that it scores that bad on I/O?

I can't select CFQ as scheduler, only noop and sio. Using No-Frills CPU.

/edit: Perhaps stupid question, but when I ran the first test (stock ROM) i had another SD-card than now. I don't know if that matters (thus, is SD card access tested or only built-in RAM)?
[HTC One V] maxwen:
Hi

There is only noob and sio in this kernel

regards

max
[HTC One V] 1ceb0x:
First thing when I told you It wasn't working, I did this:

Changed the values like "100" for one step (i saw the - at the title and I thought I should think like -100 for one step).

Then you told that for the changes to be visible in the app you need to exit the Undervolting area and enter it again.

Changed the values as you told, i.e 990 for one step, exited the UV area and re-enter it. Changes were applied.

BUT, the UI will need some work done. I was thinking of a way to only select how lower you want to take one step (e.g click on step 368, a pop up comes on the screen, and you select from there "-50, -100, -150" and so on).
[HTC One V] s4shyam95:
Ah, ok , i got u,, i can do that,, :) but it will take more time.. currently u can use this method, or ill give u a build where u can change all by a particular amount at once :)
[HTC One V] boland:
Okay, no problem, but who come I/O performance is about half the score of the stock ROM?
[HTC One V] maxwen:
Good question :)

I have to try Quadrant myself but currently have troubles with the play store :(

Will try to include CFQ in the kernel and see if it makes a diff

regards

max
[HTC One V] 1ceb0x:
This build is fine for starters. I guess in the long run it will have many features such as the one you are talking right now (change all steps at once) but you need to know the 'safe side' of One V in general. Because not all can work at -100.. Mine doesn't. I guess the maximum value is -50 or so..
[HTC One V] maxwen:
Hi

Ok. I also dont know what quadrant is doing for I/O testing - beeing also stupid :)

but the chances are good that this is the cause for the diff :)

regards

max

EDIT: Just ran Quadrant and I get a value of 2000 I/O for "noob" scheduler

I have a class 10 32GB card

So this definitely needs some investigation :)
[HTC One V] boland:
It should be 5000, I am very interested in the cause of this.
[HTC One V] s4shyam95:
Yeah, ill create custom value grps, which will have safe values :) lik +/- 100 stock is alright na? or shld i make it +/- 200 stock ?
[HTC One V] 1ceb0x:
Maybe +- 50 because my phone doesn't seem to like -100... and if you have 50 you can go e.g 750,800,850 or lower 1000,950,900.. you get the picture :)
[HTC One V] s4shyam95:
ok so these are the stock values of voltage:-

24576: 1000

61440: 1000

122880: 1000

184320: 1000

192000: 1000

245760: 1000

368640: 1050

768000: 1100

806400: 1100

1024000: 1200

1200000: 1200

1401600: 1250

1497600: 1250

1708800: 1350

1804800: 1350

1900800: 1450

2016000: 1475

So it is safe to go up to '-200' of stock values ,,,

The latest build of titanium tweaker is here :- http://www.datafilehost.com/download-1884e596.html

Testers please test if the following is working:-

As soon as u click on voltage, it show you a list like:-

Stock-50

Stock-100

and so on....,

which implies 100mV lower than the stock value

YOUR CURRENT VALUE SHOULD BE PRECHECKED HERE!!

supposing u havnt done any tweaking in voltage then, the option Stock shoud be checked..

now when u select a particular setting, lets say Stock-150

go back to the previous menu, reopen voltage, and check if Stock -150 is pre-checked now

also click on Custom button down and See if the Current values there have been decreased by 150,

you can also set custom values to voltage,

please test all of the above and tell me if its working, in case of any bug, please tell it to me,

ThankYou, took lots of efforts for this, please thank me :)
[HTC One V] 1ceb0x:
all working, except the bolded statement above. when going back and forth, the setting selected earlier is not checked, it is like you entered in that specific menu for the first time, although the changes does stick. managed to freeze my one v by pressing 125 :)

Okay, I installed the kernel from the MyOne ROM and now I score 5700 on I/O. Total score is 2100 instead of 1900 on overclocked Titanium kernel.

I/O is the bottleneck.

Ok, so i think it is ready,

i have applied some logic to the voltage part,

but i need some tester to confirm it..

so what u have to test in voltage? :-

Open Voltage and u shld see ur current setting pre checked, u can change ur setting, and check if it has changed in 'Current:-' in custom menu for voltage,

also exit to main menu, reopen voltage and u shld see the new one prechecked.

*this is a test build will upload the actual one on playstore once this is confirmed working*

I don't need it, I saw that it is possible to implement this in a kernel if it has USB OTG. However someone might find it useful to be able to read a NTFS formatted drive with the phone. But the possibility to have USB OTG in our phone would be really nice.

Hi

So USB OTG is currently NOT working with stock kernel?

Can someone conform this?

Sine actually from how the kernel is configured USB host support

is enabled and included. Also the HW specific OTG part is enabled.

I just started looking into it and have at the moment no USB OTG

cable to test it.

BTW: NTFS is in the Titanium Kernel already for some time :)

And this has nothing to do witjh USB at all :)
