under voting no.. under volting yes :D

what's the voltage?

all chip needs a tension to switch on/off of the transistors.. better is the chip, less voltages is needed to switch

a less dimension of the transistir, a better chip with less impurity, and a low freq, creates a chip witch uses little energy

more is the freq, more is the resistence, more will ve the power witch is used to switch.. if power is not sufficiently, transistor wont switch, and system crashes!

as you could know.. the arm uses the uv natively..

at 1.5ghz cpu has a 1.25 volt, at 192mhz, it's at 0.8.. so, that's an undervolt

sure.. 0.8 with 1.5ghz are too less, and system crashes

p.s. do you know why exists the uv?

when a productor poject a chip, it will do 2 things:

1) progect a chip with more frequency

2) progect a chip witch has at last that voltages

why? simple.. not all chip are the same.. in the same waffer too.. so.. productor has to overdimension the values.. if.. for ex.. productor would create a chip witch has 1ghz.. il couldn't progect it for 1ghz, or, some chip will not reach that frequency, since it's not perfect.. so.. it progects it for 1.3ghz.. and underclock it, so, the worst chip could already reach the 1ghz, and the better could reach the 1.3ghz!

for the voltages is the same.. since worst chip could not be stable, productor choses to increase the voltages, to use the worst chip too

generally, the worst chip could reach a little oc.. the better chip, a good oc..

for ex.. my chip can reach 1.8 stable with ov.. at 1.25volts u can reach 1.72;) stable.. and now, i'm at 1.56ghz with 1.087 volts..

a worst chip cant uv more than 50mv

understand?

Why not this kernel have sweep 2 wake. I really love it.
[HTC Sensation] Bluewall:
To clarify my point, some big test have been done, you can't notice the difference its so small. It can even be worse cause your CPU, because of too low voltage, make mistake and it take more voltage ton correct the mistakes. It's not as simple as you want to say.

A part of my work is about computer hardware anyway.

yep sure.. the difference are not so big.. you reduce the tension of the transistor, but the current flow is the same.. it happens because chip has a resistence..

yep.. a too mouch uv can have the opposite effect.. that's why it could be issues in the "calculation".. but.. there's only one thing, productors cant create the same chip, in the same waffer, not all are the same woth the same impurity.. so.. it has to chose a middle way witch can be good for all..

if uv is unuseful, arm should uses the same voltages at all the frequency!

a too mouch uv (or oc) can create an instable systen.. to see if it's stable, download a STRESS TEST witch force to calculate a special number.. if cpu isn't stable, program says it finds an error in the calculation, if transistors are not switched, system crashes..

i have about + 3-4 degreese of the temperature of the cpu without the uv.. so. les degreese means less energy used.. it means less power usage..

i'm not an engenier.. i studied in itis alessandro rossi of vicenza (italy).. in that school studies FEDERICO FAGGIN, the "dad" of actual chip.. he creates the lithographic process of building of the chip, and more..

in that school, electronic was the god in the earth.. you had to lear that better and better, or you will not join to the other class..

i worked with the intel 4004..

and we did a lot of test about electronic.. in memory of faggin?

that's why i say that.. i don't know how to create a new architecture, but i know what is an alu, fpu, framebuffer, cache, pipeline, ecc ecc

a -50mv is not a good uv.. it changes not so nouch..but.. i'm using a phone witch has a -175mv of uv witch has a -200 stable.. but the difference in temperature are not so mouch, i prefere to have an highter voltages (temperature increase the resiatence, it means i can have a stable chip at -0.2 volts for 40 minutes til chip reaches the 65degreese
[HTC Sensation] mike2nl:
Since i use CurrentWidget Free from store i see that use 45mA in sleep mode.

Thats to much... now i can search for the one who takes all the energy.

The ROM is NOT the one, that's the most important thing !!!

I have a lot of apps running and some servcies.

1st of all i go back to original state without any other app.

Only my lovely CoreDroid. Then i will see what going on.

Step by step a new app, and that for 12 hours.

Ok that needs time but i will find the one and will eleminate this one for ever (roar - lion angry sound) ;)

Does v1.5.2 support USB tethering?
[HTC Sensation] mike2nl:
+1 i can't say it better.

That's right and you don't know how much....

I live here in the NL and i working sometimes for a comapny who delivers the machines to make chips by Intel, AMD, Texas and so on. A team of 30 coders (me included) has done the jobs for the dual and quad core systems. It was very dispointing what means the quality of chips...

It's only 5..8% on a waver who reach the real points, the rest is 2nd choice parts used in very cheap hardware (phones, computers, navy's, and so on...). That's america, you can't do that in europe. When you do that you are out of business in no time. :cyclops:
[HTC Sensation] cezeto:
Is it possible to use ntfs formated sd card with this kernel?
[HTC Sensation] iba21:
all the CPUs are producted in america, or, tsmc is in taiwan if i don't wrong

i studyed that the lithographic making of the chip is not perfect.. the silicium is not perfect, and the.. emh.. i don't know how's the right word, in italian "drogaggio", it's the action with trasform a semiconductor in a conductor (to crate the source drain and gate of the transistor, it's not perfect, so, it could be a better "drogaggio", and a worst..

i don't know if, in 2012, it could be a possibility to create a perfect chip.. but.. nvidia did it with the companion core.. so.. it "could" be possible, maybe, the costs are too hight..

for me, it's normal if all the chips are different

intel and amd did another thing.. they progects a chip, and releases it with same area DISABLED!!

2 ex:

1) intel creates a chip, underclock it, and lock some piece of the cache.. so, for ex, with the same chip in the same waffer, it could be create a chip witch has a quadcore with 3.2ghz and 4mb of L2 cache.. and in the same chip, for ex, a quadcore with 2.8ghz and 3mb of cache.. with 1mb locked..

2) amd creates some quadcores with has 1 core disabled, and sold that quadcore as a three cores witch has 1 core disable (60& of those cores are demaged by a wrong chip production)

i have a CULV processor.. it's an SU2300, dualcore with core 2 duo architecture and 1mb of cache and 1.2ghz.. i'm running it at 1.88ghz with + 0.16Volts, stable.. it means it was progected for a 1.6ghz at last..

after some searcing, i knowed that the SU2300 is an SU9600 with portions of the cache demaged, and, intel sells it with a lock at che cache for less dollars..

the su9600 can reach the 1.6ghz, i can reach 1.89ghz stable with little oc.. and i have a 1.2ghz natively.. it means i have a +55% OF OVERCLOCK.. it's a record.. with air.. not water or azote ;)

that's the real..

but.. i didn't know that some chip could have about 5% of difference in the same buffer.. but, i suppoused it..

my arm chip is stable with a stress test at 1.56ghz with 1.087Volts.. friends in this forum can't boot if they try to force the 1.1volts at that frequency.. boot.. not a stress test.. a boot..

i'm luky, and it could be the better, or one of the better sensation's SoC in the world

than you four your knowlege :good: much appreciate

---------- Post added at 01:49 AM ---------- Previous post was at 01:43 AM ----------

don't know but.. it's not a good idea..

if you have files over 2gb, format it in EXFAT, or, better in ext2-3

the "permission" settings of ntfs are not so good in unix system (i have a mac mini, i know what is the ntfs for it.. i have to install a driver emulator.. that's not necessary for fat system.. OSX supports exfat partitions natively..

p.s. i'm not sure if sensation supports exfat file system.. :silly: you have to try :good:
[HTC Sensation] mike2nl:
Hi iba21,

bro... now we are talking over real things. I had never expected that more then one (me ;)) knows so much over chip production too. Thats amazing to know that someone more is here on XDA.

I think we need a new group on XDA = Technolocial Devs

I hope the mods reads this sometime?!

Thanks for your knowledge, bro. I hope we can talk sometime more about that.

BTW1:

sometimes i give up here on XDA because the to short on KnowHow in that case.

You make my day, bro and gives me hope for more users with KnowHow. Thanks...

BTW2:

the machine engeneering group is named ASML Eindhoven. Search for it and we talk further.
[HTC Sensation] iba21:
eheheh.. i'm not en engenieer.. i was an electronical student in the hight school of federico faggin.. all of the students knows the base of electronics as well as it could be possible, maybe, in onor for Faggin.. ;)

i'm an hi-tech "fan".. i love the tech.. i have an hakkintosh (i know it's illegal..) and a good phone.. but i'm not a nerd.. i'm a radio speaker :p

so.. don't expect on me the new nirvana, i know how works a chip, since i studied the structor of the chip, and how to create it, but, i don't know how to do to create a new architecture (it's not so easy).. i studied the hardware components of the chip.. the "porte logiche", i think, logic ports.. AND OR NAND NOR etc etc.. that's why i know a little bit..

but.. if you want.. i knowed federico faggin, it's my townsperson, now, it's an old man, but, it's incredible what he did for the tech..

i sad him i'm much thankfull for your great work, maybe, without you, we will never have this conception of pc, and phones, since, all of tech is created from a transistor.. he creates the first "little" transistor ;)

he progects the MOS

Hey Seb, would it be possible to have the Lagfree governor added in the next version?

Well that's a matter of opinion. I personally don't use S2W, but others do and want it.
[HTC Sensation] galaxys:
I could care less about S2W... Have no need for it!
[HTC Sensation] noodles2k:
good for you...
[HTC Sensation] naughty6t9:
It is yet another opinion dude. If u want use it else let others use it who wants it with this awesome Kernel...

Well we have another option which looks sexy when u wake Ur device that way infront of Samsung users :cool: also our power n volume buttons don't get spoiled..

Sir I request u to add S2W and USB Fast charge in Kernel..
[HTC Sensation] mike2nl:
I hope you all know that s2w is an extra service that must be run, and that decrease the power of that fantastic ROM.

Everyone who needs s2w whyever, take a different rom then you get.

I think for shure that Sebastian will never add strange gimmics like that.
[HTC Sensation] Yank555:
Sorry to bump in ...

S2W is anything but a service ! It is "simply" a few extra lines of code added to the touchscreen driver (that is in the kernel and has nothing to do with the ROM running on the kernel btw).

Sorry for interrupting, you may now continue fighting over it's usefullness, fanciness ...

It's up to Sebastian only to find it apropriate to add it to his kernel or not.

JP.
[HTC Sensation] Stephen:
This kernel really is a brilliant kernel. I just miss sleep to wake too much! I know you are all going to jump me for saying that but I do find it really usefull to have! It would make this kernel the ultimate kernel for me. Battery life is awsome and with viper rom it is as smooth as anything.

[HTC Sensation] UnixSlayer:
This is GREAT News Sebastian! I was hoping this would come about. The s2w has been holding me back using your kernel. Which I used in the past. I've already returned one Sensation because of a worn out power button. Thanks! :D
[HTC Sensation] sIpInWiT mYdRoId:
Thats funny, It almost looks like sebastionFM had to add Sweep To Wake just cause his thread was being clogged by people excessively talking about it. lol, I've never wasted my time with this option personally. Please no one take this as rude or take offense to this but just like the comment a few before mine, or i think the one above mine says, Why do you guys have to send your sensations in for repair due to a worn out power button. The power button is just a little piece connected to the case, which is something warranties don't cover, cause they don't cover the case. Just find it odd people are having to send in phones to get a little plastic button repaired when they would end up charging you the same price as a brand new case. Just my thoughts,lol. Because if it is the actual piece connected to the phone, that is a very hard piece to go and wear out.
[HTC Sensation] UnixSlayer:
Repairing your phone voids the warranty. You change a part, and HTC will let you know. As long as my phone is under warranty, I'll let HTC do the repairs. Nobody is forcing anyone's hand chief. It's an option Just like any other mod.
[HTC Sensation] SebastianFM:
You'll change your opinion about s2w when you'll see my work. :laugh:

I think no one care about power button. It's just cool when you can wake up and unlock phone with one single sweep or touch.
[HTC Sensation] UnixSlayer:
It's also convenient. Sebastian.... You have now provoked my curiosity. Can't wait to see it. :D

[HTC Sensation] sIpInWiT mYdRoId:
Thanks for the response. Maybe i'll try it seeing this is my favorite kernel. But what i was getting at with the others about the power button. Yes i know when you try to repair the exact phone itself it voids the warranty, but one the phone is bought, if via a store like tmobile, the only thing covered under warranty is the actual phone. May be different in other countries though because i beat the crap out of 2 usb port brackets on my sensation and they never repair it just send out new phones. But as mentioned, without another battery, battery door,etc... cause they dont cover those pieces under the warranty.
[HTC Sensation] 69gm:
For me it IS about convenience as well. When I drive, I put my phone in a dashboard cradle and use it as a GPS. When I make or receive phone calls via my bluetooth, my phone blanks out...just the usual screen turning off. However, sometimes after the call, my screen remains off. In order to see my GPS again, I have to wake my phone. S2W has made that process very easy. Prior to that, I would have to blindly reach for the power button which isn't as easy to press while driving. Also since the phone is in a cradle it's not as easy as simply sweeping a finger on the screen.

Yes it's a cool function...but this is just one illustration of how it can be convenient...and it has nothing to do with wearing out your on/off switch.

Thanks for your time!

Sebastian, I know you originally said you wouldn't incorporate it in your kernel. I want to thank you for being such and awesome and flexible dev that you'd be willing to revisit your stance on this. Sounds like you have something extra special cooking! Can't wait! :D:cool::highfive:

[HTC Sensation] axetilen:

[HTC Sensation] StuartTheFish:
How am I inviting trouble? It was a simple question, how can people flash anything if their power button is faulty?
[HTC Sensation] Stephen:
There are a few ways. You can flash kernels and I believe roms by using fastboot. You can also use fastboot commands to reboot the phone and reboot into recovery, bootloader etc.

Just about the only thing I think you cant do with fastboot is power off and on!
[HTC Sensation] Yank555:
Using extended power menu, or apps the boot into recovery, or using adb to boot into recovery ...

Just a few ways I would see off hand ;)

[HTC Sensation] StuartTheFish:
Yes, but to even be able to do all that, you need to have flashed things in the first place, using the power button.
[HTC Sensation] Yank555:
If you activate USB debugging on a non rooted ROM, you should be able to boot into recovery, bootloader etc. Rooting uses this on the Sensation if I remember well.

JP.

PS: I'm just playing along here, no hard feeling I hope, I found it challenging to see if it actually would be possible without power button ;)

I have already faced this many times. However, using terminal to run this script will show the issue like you image. copyit it to system/etc/init.d and set permission to 755 or 777 -> do a full reboot and it will work correctly

p/s: a space at the end of the script doesnot affect anything -> many scripts from other DEV like arhd or vipers still have a space at the end and I'm sure all the scripts working correctly in my device. If you dont believe me, you can use system tuner to run system/etc/init/qcom.post_boot.sh and it must show some error lines but it is a SYSTEM FILE, not something I create

All the error will be solved after you copy those files to the right place and make a reboot

:D
[HTC Sensation] StuartTheFish:
Of course there's no hard feelings fella, it's only the internet! How do you boot into recovery and bootloader on a non rooted ROM though? There's obviously more to it than just enabling USB debugging, can you do it through commands via a pc then?

Still doesn't help you turn on a non rooted phone if the power button is broken though. ;)
[HTC Sensation] Yank555:
Once it's on, you can use ADB on the PC side, you have no root access, but I think you could still reboot into fastboot / bootloader / recovery.

But hard to tell, I've never had an unrooted phone for more than a few hours each time :D And I'm not willing to unroot just to test this :cyclops:

Hmm ... gues you found the "kills it all" point, you better have activated USB debugging before breaking the power button ;)

no. it doesn't support, but you can use setcpu or system tuner to do that

however, it seems to me that it sometimes make my device crazy after turning on the screen (system will stay at screen off setting without changing back to screen on settings). Setcpu I havent tested
[HTC Sensation] Yank555:
SetCPU (Play Store version) has user definable profiles, it's not free but it's really worth it. I do use it with profiles on my SGS3, works like a charm, I have profiles for :

- Screen off (very low frq.)

- USB charging (lower CPU frq. so it charges a little faster)

- AC charging (full CPU frq.)

- battery at 15% (lower frq.)

- battery at 10% (even lower frq. plus conservative governor)

- mobo player (full frq.)

And you can set priorities, which profile wins over which.

JP.
[HTC Sensation] noodles2k:
Try it. I assure you it doesn't work. Also if I exec sh any of your other scripts, they run fine.

Post boot gives errors because Cpu1 is offline, whereas the voltage table always exists.

A white space at the end of a pipe to a file might be seen as part of the filename, which is why it doesn't work correctly.
[HTC Sensation] noodles2k:
Here's a better example.
[HTC Sensation] axetilen:
ok. you're right. 87.5 is not working. everything else is fine

problem found: 87.5, I created by microsoft word, not notepad++. Added a space at the end but still not work

after copying all the script to notepad++ without changing anything (added a space too) => work correctly
