no idea and wish you could answer....

did you mean the userspace governor we see on stock kernel or otherwise i dont know what you meant but certainly would like to know

look bro i am an RC and so against the "wise cracks" if someone asks a question

i didnt ask a stupid question, im genuinely interested in knowing how NV is dealing with this
[HTC One X] airchie:
I too am confused by this.

I get the feeling nvidia are doing something bad?

Its preventing us from controlling the CPU/GPU/Voltages/Clocks/Cores effectively?

Userspace makes me think it would be something we could control?

I realise this may seem like trivial stuff for you, and I appreciate you do devote a lot of your own time to XDA and your kernels etc, but a more helpful answer to the issue would be appreciated. :)
[HTC One X] :
..franco just wanted to say that you dont got much space to control things yourself. If its the cpu frequency, running cpus, etc. you even cant control the strength of the capacitive backlights...on qualcomm you got that possibilities.
[HTC One X] the_maker:
Hahaha, my intuition says that the next big fiasco will be the social networking online as we know it ;)
[HTC One X] lesscro:
i manage CPU UnderVolt by descending -100mv for each value... seems to be good... device is full charge.

I tried first -175mv... to much low.. device restart on back button... :p
[HTC One X] jonas2295:
Yeah tried your setting as well an its great :) standby is 3mah now.. Before it was like 10mah
[HTC One X] ingineru:
I am struggling with set cpu....i modify voltage press save, but nothing changes visually, then press save it says:"error backing file, is your storage unmounted?", if i press the checkmark button it force closes....
[HTC One X] jonas2295:
I use franco app for voltages and set cpu for cpu control as on Franco app it crashes when tapping the Option.
[HTC One X] franciscofranco:
r11 is up

* Decrease minimum allowed UV from 600 5o 500mV

* Lots of cleanups to cpu-tegra.c and cpu-tegra3.c routines - HTC and NVIDIA need new engineers...

* A little cleanup to tegra3_clocks.c

* Another cleanup to Ondemand governor to simplify their derp code

* Add a new debug line during the undervolt routine for easy check if the voltages were really applied to the dvfs struct - check it via dmesg

* Charging should now be faster
[HTC One X] NickDunn:
thank you Franc. :D
[HTC One X] hosmsdos:
Hey franco when i flash your kernel after like one day i start to have flickering on my screen i flash back stock kernel and flickir is gone. Any idea why im having this issue. I tested your r9 many times and same thing happnes again. Is there any changes on the latest kernel that might prevent this. Thanks
[HTC One X] hamdir:
setcpu does not support tegra3

franco, amazing work man I think its time to give HTC some hard time

the one x is a gaming device crippled without ur kernel
[HTC One X] B-Man2005:
I heard that it will never be possible to overclock the European one x ...

Is that true :eek:
[HTC One X] jonas2295:
But why is the cpu not going anymore up than 1,3ghz if I set it to?
[HTC One X] NickDunn:
i wanna beat s3 as well.. lol.
[HTC One X] Daekin:
hahah why are you so desperate about OC right now? like Intel emplyees said - Android is not optimized for multicore systems...and we have powerful 4 cores so we have plenty of room for improvments before we would need overclocking....
[HTC One X] B-Man2005:
Hahaha... Hmmm I think iam kinda addicted to overclocking ...

Aaand flashing :rolleyes:
[HTC One X] franciscofranco:
Because HTC morons don't release their sources in time of their RUU releases. We are 2 updates behind in terms of kernel sources. Its fixed on the latest RUU because they already fixed it on their kernels, but no source. Just like Linus said "**** you HTC."
[HTC One X] jonas2295:
Well what I would suggest is to run the latest htc kernel for some hours.

Set display timeout to never and full brightness.

Get a white picture etc and leave it this way (may put it on charger) for 2 hours.

I have no flickering anymore and back to franco :)
[HTC One X] LorD ClockaN:
didn't he said "**** you nVidia!"? :)
[HTC One X] blueboiiz:
Yeah he did:D
[HTC One X] franciscofranco:
He did, but I gave it a second go, HTC deserves it as well ;)
[HTC One X] LorD ClockaN:
I thought you did :)

Will try r11 as soon as new AOKP is uploaded
[HTC One X] franciscofranco:
I added a new pr_info debug when a new voltage is applied to make it easier to check if the dvfs struct has indeed the new voltages - following one of your latest posts concerning the voltages stuff. I can undervolt the first 7 entries to 500mV and no crash... but the voltages are really applied... makes me wonder how can this device handle such low voltage level.
[HTC One X] -juanito-:
Can we get r11 Repacked for ARHD 7.0.0 ??
[HTC One X] :
You would have thought they'd want there phone to be no 1? It makes you wonder what kind of f****ing idiots are running these companies
[HTC One X] LorD ClockaN:
you mean the lowest 7 entries??

really weird...
[HTC One X] GabrielSousa:
I have the last 12 entries with 500mv ;-)
[HTC One X] LorD ClockaN:
than UV ain't working...
[HTC One X] ingineru:
And is that big undervolting noticeable on battery life?
[HTC One X] DeeZZ_NuuZZ:
when i undervolt it....my phone crashs :D not with r11 but r10 etc...where i undervolt to 670 something :D and it crashs -.- can someone say me perfect voltage list???
[HTC One X] franciscofranco:
Check dmesg when you undervolt and you will see the voltage struct being updated correctly.
[HTC One X] LorD ClockaN:
than we can really UV this sucker!!!
[HTC One X] mwilky:
What were they thinking putting the values so high if so many people can UV this much?
[HTC One X] ossy1337:
It would be really nice if someone who already found the lowest stable voltages for every frequency could post a voltage table (I know that it's diffrent from device to device but would still be useful)
[HTC One X] mach0boi:
Doest init.d work in this kernel without repack?
[HTC One X] franciscofranco:
I believe so yes. If you get some free time can you do some testing on this subject?

Yes.
[HTC One X] henrikvn:
r11 using ramdisk from 2.05?
[HTC One X] mach0boi:
Franco just want to confirm that I can also adjust voltages using system tuner. The frequencies doesn't show right but the voltages is applied correctly. For those who want to set the voltages on boot, they can use system tuner. Cheers :)
[HTC One X] waz675:
In main, click menu, goto device selection and try continue recommended and/or the other 1 or 2 options. I did this to get my one going.
[HTC One X] ossy1337:
I can confirm that 500 mV is stable for me till 1150 mhz ..appears a bit strange to me since I doubt that such a dramatical undervolt is possible. Could someone who is more familiar with that explain that?
[HTC One X] zidane2k3:
Problem solved. Phone.is booting again now
[HTC One X] waz675:
While it may appear stable you _may_ get i/o errors such as when saving files(including system files) so you may get a broken OS after time (as files may not save correctly at times without knowing). These errors may only appear with special(long) type of math equations/running scenarios or heavy 'disc activity'. You really need total stringent stress tester software and make sure it's '100% stable' so to speak. Can't help with software for phones only know PC stuff for under/over clocking stuff.
[HTC One X] ossy1337:
Thank you for this advice. I will do some detailed stress tests tomorrow in order to find the lowest voltages for each frequency without harming the system in the long term. Ofcourse I will provide the voltage table when I'm done. Looks like there is some serious battery saving potential.
[HTC One X] waz675:
Thanks for the time spent doing the table to base our UVs with. If our 2yr old wasn't sick with cold/flu and our 1yr old teething I'd have time and motivation to test out the UV. Alas, finding out kids can be somewhat demanding of time ;)

Awesome stuff happening ATM all round with HOX, definitely happy I got one.
[HTC One X] zidane2k3:
So, I've got the last 7 frequencies at 500 with the others from there -100. These seem to give me the most stability. So I'm gonna run with those for the time being !
[HTC One X] shree.cse:
My battery was drained 22% in the last 10hours, and this is my first experience to have such a bad drain on standby/deepsleep. What I did was decremented each frequency's voltage by 100mv in the last night. And I am not sure about what I did and I incremented the values to default, I will check again. Thanks Franco
[HTC One X] lesscro:
As i say yesterday... i undervolt all value with -100mv...

92% yesterday before going sleep - flight mode activate

this morning - 07h00 -> 92% battery = NO DRAIN

Now i m on R11 (thx Franco)... will se if same result tonight...:D

I think UV -500mv is very high... as say a previous user, maybe can work but need test report in real usage !!!

By the way i want decrease only if needed... If OS seems to be work like a charm without extra dain... then i will be happy 1x user
[HTC One X] Atrixx:
There is a problem with the software accurately reporting the battery in deep sleep. I can almost guarantee that within you using it for 5 minutes, it had dropped 5-10 percent.
[HTC One X] Alhaddad:
thanks for r11 franco... any change log for that?
[HTC One X] starbase64:
yes, one page back
[HTC One X] Alhaddad:
thanks.. although i was refreshing the 1st page :p
[HTC One X] irharrier:
I dont have any idea of whats is undervolt:D

so can someone give me a link of a thread (compatible with this kernel)

or explain it to me directly?:D
[HTC One X] waz675:
Depending on the kernel, software like setcpu or systemtuner or francoskernel updater can change the value for certain speeds of the CPU to use less voltage for said speed. I.e our HTC one x default is 1500mhz. Certain programs can make the HOX run at lesser (or higher if able) speed like 1200mhz. The CPU uses certain voltage at various speeds (at the 1500mhz or other speeds higher or lower) to power it and keep stable. For possible power saving, we try to run those speeds at lower voltage so our battery charges last longer whilst keeping the CPU stable.
[HTC One X] Sckank:
My dear franco, can you add ntfs support to the kernel? I hate the fact that I cant copy <4GB to the phone.
[HTC One X] irharrier:
wow i didn't expect a good answer like this.thx dude.

which software does the best?:D and what is the most stable setting that you can recommend ?!! (I hate it when my phone crashes:D )
[HTC One X] jonas2295:
Well what I use atm is set cpu to have a bit control over cpu frequency.

And francos app to undervolt the frequencies.

I am currently UnderVolting with at all frequencies - 100 :). But still need testing :)
[HTC One X] Goku80:
check that the frequencies that you are using on setcpu do not stick as the app is still not compatible for our phones. well do not know what you use for the min frequency but whatever you put it on it will revert back...you are better off controlling the frequencies with Franco's app
[HTC One X] jonas2295:
I can't control it over franco app as it FC as soon as I tap the option -.-
[HTC One X] GabrielSousa:
update to the last version
[HTC One X] jonas2295:
Stupid me :D

Had it already but didn't test it yet. Thanks for the heads up.
[HTC One X] geenyous:
Usually I'd say you are right, but he had it in airplane mode all night, no wonder there was no drain... :rolleyes:
[HTC One X] starbase64:
Hi,

i've undervolted with r11, but drain is always 20 - 30 mA in standby.

Faux 003b7 has 2-5mA in standby :eek:

480MHz @ 600mV

650MHz @ 650mV

780MHz @ 700mV

CPU is stable but more battery drain.

edit: option to set max frequency don't work! (in franco app)

cheers

starbase64

Faux in his kernel have low min frequency 51MHz But I couldnt set it always back to 100MHz and min frequency is 100MHz not 102MHz like on franko.I tested both kernels and frankos is much faster so I use his.I noticed that when unlocking phone on faux need to past 1s for screen to go on.

FRANKO AND OTHERS who know more then us can maybe explain this please ty.

And about drain I have from 4mA to 40mA.After high usage (3d games)have high drain when phone is locked,THIS ALL SO can explain someone who knows more then me TY
[HTC One X] geenyous:
was on Faux3b7 for several days and never had a drain below 20-30. Which app do you get those numbers from?

I used Battery Monitor Widget.
[HTC One X] starbase64:
i've undervolted

same
[HTC One X] airchie:
They have to cater for the lowest common denominator. I suspect they're speed-binning the processors and using higher voltages to gain higher yeilds.

As you say, it's always going to be different for each processor but would be nice to see what others are able to get. Worth remembering though, as soneone said earlier, that just because the phone doesn't crash straight away with a specific voltage, doesn't mean its stable. File corruptions etc may be happening during various loads that don't manifest any symptoms until your phone crashes and doesn't boot again.

Indeed, would be interesting to see some results from various users. What would be better is some way to do consistent testing to ensure the results submitted by users are accurate. ie, set the voltage and stress test the phone to check stability. Mind you, since we can't reliably set clock speeds we can't stress test say 700MHz with a specific voltage as nvidia will clock the core higher as you're hammering it. :(

The most stable setting we could recommend is to keep it the same or even increase it! That would give the best stability but the worst battery usage... ;)
[HTC One X] franciscofranco:
I thought I had done it. Thanks for the heads up.
[HTC One X] LorD ClockaN:
You can't lower drain from 20mA to 2 with undervolting!

The device itself should be around 2-5m when it goes to deep sleep..

If you're not getting that kind of drain, than something is keeping the device awake

[HTC One X] lesscro:
i tried your values on my config base...

then added

480MHz @600mV

650MHz @600mV

[...] all other values -100mV

seems to be stable...

Thx for it... i will try... but i think is low...
[HTC One X] KLUVJ:
how do i check the battery use on standby？ where do you read the 3mv？ cant find it anywhere in battery monitor widget. how long to i have to not toich ny phone to check？
[HTC One X] Sckank:
Very funny Kevin :P :)
[HTC One X] KLUVJ:
no seriously...i know a lot and yet so little at times...sigh

TELL ME....as i undervolted and want to make sure im not getting excess drian
[HTC One X] pewpewbangbang:
Download battery monitor widget free from market.

Then open app and click history. Don't exit it but home button out of the app so it can record in the background.

In settings you can change things like how frequently to check usage. Every 60 seconds or every 2 minutes etc...
[HTC One X] KLUVJ:
ok, after i set that, in order to test the battery lost when not using the phone is simply turn off the screen for a few secs right. thks
[HTC One X] emmaair:
If i undervolt my device and apply the values and reboot everything is like it was before.. is it normal? Are the Voltages applied but it dont show them? Or maybe ive missed something? :P
[HTC One X] LorD ClockaN:
@Kevin:

depends on what you set for logging interval
[HTC One X] KLUVJ:
awesome..kinda weird data though. stopped touching my phone starting at 50 something
[HTC One X] KLUVJ:
voltages dont stick for safety measures. so that there arent bootloops and instability if ur phone cant take the uv
[HTC One X] Goku80:
once you set your settings do not reboot. leave it as it is and you should be fine. voltages not being stuck upon reboot is due to a safety reason or something like that Franco said.

EDIT: beaten by Kevin:D
[HTC One X] crescal:
UV doesn't stick after reboot. Franco has mentioned it many times..
[HTC One X] Goku80:

[HTC One X] colobos:
What's the best thing to use for uv? Also does it make much of a difference?
[HTC One X] hamdir:
did anyone check if the UV values changed in the new stock kernel in the new 2.05.401.2 base? because its much less hot than before

is there a way to check those
[HTC One X] emmaair:
Thats what i wanted to hear :D thx

[HTC One X] hamdir:
well many people are reporting that the device can handle -100mv

im using system tuner to set -100 on all levels (incremental -25)

seems to be working fine :eek: no flicker and i ran nova3 without a hitch

but im curious if HTC lowered the values in their latest stock kernel from the test base since its a lot less hot
[HTC One X] KLUVJ:
i did uv in all for 100, then the lower 6 i lowered 50-75 more LOL,
[HTC One X] colobos:
Probably a stupid question but what app is best to do this the uv with and what sort of battery increase are you guys getting off uving
[HTC One X] ClydeB1:
I use System Tuner and UV by -100 across the board. Last night I had drains of -2 to -3mV consistently (although admittedly in Flight Mode). During the day today with normal mobile data on and recently with wifi on as well and am getting between -9 to -20mV drain on standby.
[HTC One X] colobos:
And what does that actually equal in real world use longer screen on time? Overall battery performance or just standby? Also should i change cpu speeds lower or does that not currently work on the one x ? and do the values reset on a reboot ? thanks for help
[HTC One X] limpep:
I am guessing this is a known bug but when you hit set cpu on boot the app crashes. I do have the lastest build from the play store.

i hate being in that position but cant save my self :P. I use system tuner and battery widget.i found the voltage tab so i was happy, i tried to undervolt it and there the problem came.how can i see which speed is on the specific voltage? the only thing i am seeing in voltage tab is one blue bar which is either 0 or 1 Mhz and next to it the mV.i thought i should merge the blue bars with the cpu freq as seen on the other tab but no luck. any help with it? kudos

Franco maybe it makes sense to add exFAT support in terms of speed, not NTFS???
[HTC One X] srashedian:
Hello;

Sorry guys, but I can't find the r11 change log anywhere! Am I blind or there is actually no change log for the latest release?
[HTC One X] mick353:
This is how to set UV at boot with franco R10,11 via system tuner and franco updater

Use franco updater app from the market... the voltages are in the same order.. you can also view your settings as you change them in system tuner - from the franco updater app

i also save my final settings i've set in system tuner, via the franco updater app and give custom name.. have about 5 versions now.. Easy to reload.. With franco you don't get set voltage at boot - however with system tuner you can set the - set cpu settings at boot option to reload your voltages .. this can be verified after boot view the frano app...

Happy undervolting ppl!!!!!

---------- Post added at 04:24 PM ---------- Previous post was at 04:14 PM ----------

Guys i'm pretty confident as per previous post and battery monitoring that i'm getting significant UV battery saving (still way too dependant on screen usage but unavoidable).

Also that i'm' auto UV at boot - so for all intents and purposes the system works.. Of course our fab devs will tweak and refine more..

So I ask is there any resolved issues in this space re UV and boot-time or outstanding questions.. Lets sum them up and perhaps provide something the devs can provide for everyones benefit..
[HTC One X] Sckank:
Add exFAT, NTFS and EXT4 :-) EXFAT alone still, should do it. But can it be done?
[HTC One X] Danzano:
The latter of the three :)

This link gives me a malware warning with Avira AntiVir :confused:

Thought phonearena is kinda "official"?

Maybe they got hacked... or most probably false positive.
[HTC One X] EazyVG:
For reference to newbie, here is my VDD table. I am using System Tuner Pro to set values, and even though one can using this app set the values to load automatically either after boot or during the boot (with init.d) - both available in settings, I prefer to load manually. The reason was mentioned in my previous post pertaining to safety reasons.

650 mV
675
700
725
750
762
825
900
925
950
975
1000
1025
1050
1075
1100
1112
1137 mV

As you see I opted for -150mV for first 7 speeds/CPU states (below 1Ghz) and the rest -100mV. Not too aggressive and is stable for system to operate while saving some battery juice.

P.S. It would be nice if the Dev can come up with his own suggestions and post it on the first page as ref VDD table. Also look forward to your app to have states/voltages both present so I can then jump to it instead of using STP app.

Thanks for awesome kernel.

Just out of interest is it normal to lose 60% battery during the night phone screen was off entire time but for some reason there is no signal what so ever in my bedroom (only just found this out) and mobile network was on so would it of just been my phone searching for a network all night that did it or am i missing something ?

[HTC One X] colobos:
everything like that was off I dont even use twitter I was just thinking that it would be my phone searching for a signal ? cause of 0 reception ?

yup but the phone is charging at the moment due to it dying during the night lol and that much drain wouldnt be down to searching for a 3g signal all night long ?>

I got a lot of **** synched but I have very little drain. That is facebook, 2 email accounts, a planner and a couple in google reader. I usually loose 5-10% over 8h. Never had so good battery, not LG or with samsung. Love it :) So 60% is way off :-)
