Hi stratosk

In motley continued thread I found:

And about hotplugging, did you see new franco hotplug driver? It have only two modes: dualcore for lightweight tasks and quadcore for full performance.

I have tested sometime ago with motley kernel, between minimum online 1core and 2core there is noticeable difference but between minimum 2 or 4 core I didn't see any difference.
[Nexus 4 Original Android Development] stratosk:
Thanks for info. Yes, I saw his hotplug driver.
[Nexus 4 Original Android Development] stratosk:
I was testing these tunables today:

Touch load: 75

Touch load threshold: 16

Touch load duration: 1500

Tomorrow I will go higher in touch_load...
[Nexus 4 Original Android Development] coloxim:
Is this for the screen. ?
[Nexus 4 Original Android Development] stratosk:
These are values for new ondemand tunables for 1.4.0 betas
[Nexus 4 Original Android Development] vandizzam:
I can't find these options in the semaphore app
[Nexus 4 Original Android Development] stratosk:
Semaphore app doesn't support these yet.
[Nexus 4 Original Android Development] coloxim:
Ahh... Ok...

Thanks..

Can I do it with set CPU?

[Nexus 4 Original Android Development] BlueFlame4:
Well if our CPU had proper C States, that'd be great... I read a couple of pages about it and it turned out that cpu1-3 won't go below C0 whereas cpu0 can easily hit C3. Is this a hardware limitation (maybe even a feature?) or can this be improved by kernel hax?

Sent from my Gameboy Color
[Nexus 4 Original Android Development] thracemerin:
Hardware limitation on this version of the chip, but cpu1-3 have to be hotplugged off (hotplug off is deeper than c3 technically) for cpu0 to go into the lower states anyway, so no hotplug solution prevents this anyway.

Trying this setting with the last beta. It seem to work without lags.

Hi stratos

Been away from semaphore for a while but flashed latest release earlier today, Great work and running superb. Hope you are well.

Stupid question...how can disable green led when the battery is full? I change it with app..but doesn't work...
[Nexus 4 Original Android Development] apatal:
Make sure your ROM doesn't have battery LED options and the battery full notification light isn't enabled. :)
[Nexus 4 Original Android Development] coloxim:
I'm sure...the led turn on while I charging and the phone is off..
[Nexus 4 Original Android Development] stratosk:
If the phone is off, Semaphore manager can't override default kernel settings.
[Nexus 4 Original Android Development] coloxim:
So when the phone is off... I can't turn off the led? Cause I recharge my phone when I sleep... And so the led stay on many hours..
[Nexus 4 Original Android Development] stratosk:
No, you can't turn it off.

It will stay on when the phone is _fully_ charged.
[Nexus 4 Original Android Development] coloxim:
Nooooo please... Can you change it?

Or do a long pause with pulse...
[Nexus 4 Original Android Development] BlueFlame4:
Can't you just overwrite it with Semaphore Manager and keep the phone on? I don't quite get why you wanna turn your phone off while charging.

Sent from my Gameboy Color
[Nexus 4 Original Android Development] stratosk:
Maybe, I will disable the default led triggers because some people complain about incompatibilities.

But why you want it disabled?

You said you are sleeping when you charge your phone. You don't even see it. :)
[Nexus 4 Original Android Development] coloxim:
Aahahaha you are right...but I'm afraid let the led always turn on many many hours...

Maybe is not a problem..I don't know...

I can't dream well if I think the led next to me could be on...

Hihhii

Forgive me..

Lol.

I'm at 84% after 1 hour but I've never complained about my battery....... I just use my phone a lot and charge when and if needed. My phone is permanently in my hand, I can't leave the damn thing alone. :eek:

[Nexus 4 Original Android Development] Lucenzo7:
Just flashed the kernel, there's a red light that flashes very slowly (like 30 seconds slow fading), and I can't turn it off unless I lock the screen.
[Nexus 4 Original Android Development] Naa Laa:
Go to semaphore app and under tweaks turn it off where it says LED triggers.
[Nexus 4 Original Android Development] emanuele1986:
For example i open an app, after exit or close sometimes the animation of home show micro shots and also sometimes when i go in the application/drawer menu and scroll the app there are micro shots.
[Nexus 4 Original Android Development] Millionas:
Have had several soft reboot the last six weeks.

Using an old version of PA. Been offshore for six weeks and no possibility to upgrade ROM, only kernel.

But have only experienced reboots when using OpenVPN the six weeks.

Is it ROM or kernel related?

Please find attached last_ksmg after reboot.

http://db.tt/oUo5cmKi

Thank you.
[Nexus 4 Original Android Development] stratosk:
Soft reboots means that the kernel has not been crashed.

So, there is nothing logged in last_kmsg (it seems fine).

Most probably, it's a ROM issue. But if you want you may post a kmsg and a logcat after a soft reboot.
[Nexus 4 Original Android Development] Millionas:
Will update my ROM when I get home tomorrow, hopefully the problem is gone.

Thank you for your time and a great kernel :)

1.4.0b5

- Introduce dynamic hotplug driver

- ondemand: Change default touch tunables (touch_load: 75, touch_load_threshold: 10, touch_load_duration: 1300)

- ledtrig-thermal: Rework the code

About dynamic hotplug driver.

It's a very simple driver that uses the calculation of load by ondemand governor.

The logic is very simple. The driver calculates the average load of CPUs every 0.5sec.

Over an average load threshold cores goes online and stay online at least for 5 seconds.

Under this threshold they go offline one by one every 5 seconds.

Minimum online CPUs is 2. But, I will introduce a tunable for this.

I will also add a tunable to enable/disable this driver.

The goal of the driver is to put additional CPUs online fast enough and offline them after long time (5sec) of inactivity.
[Nexus 4 Original Android Development] a g bell:
What is the advantage of the driver?

Sorry if that sounded disrespectful its not meant to just wondering is it going to give more battery or something else?
[Nexus 4 Original Android Development] stratosk:
As I said my goal for 1.4.0 is to remove mpdecision and have 4 cores online all the time.

This needs some more energy and produce a little bit more heat.

I made this simple driver not as a substitute of mpdecision. Actually it works in a different way.

Mpdecision put CPUs online when the load is high or when the user touch the screen.

This driver tries to put CPUs offline when the system does not need them.

So, I think we need this driver to offline a couple CPU when the system is pretty quiet.

Of course there will be a tunable to totally disable it and have a pure quad core phone.
[Nexus 4 Original Android Development] a g bell:
I like this scales nicely:)
[Nexus 4 Original Android Development] coloxim:
But... Sorry, you want all CPU online and now trying hot plug?

So you leave mpdecision? Are you sure about it ?
[Nexus 4 Original Android Development] stratosk:
Yes, I'm pretty sure. :)

Because, with this approach I can have 4 cores online.

But somebody else may choose to enable the hotplug driver and save some battery.

Also we may have a fully configurable governor regarding touch boost and also a configurable hotplug driver.

So, everybody will be happy. :)
[Nexus 4 Original Android Development] coloxim:
OK...but hmdo you think 4 core online is better than mpdecision?

And hot plug driver is better? Mmnnnn....
[Nexus 4 Original Android Development] apatal:
Sounds promising, [MENTION=3750240]stratosk[/MENTION]. I'll test it out for you and report back. :)
[Nexus 4 Original Android Development] stratosk:
Yes, 4 cores online is better than mpdecision regarding performance.

And I just need a hotplug driver to offline CPUs on pretty low load.

But, let's test the new beta and talk about the facts later... :)
[Nexus 4 Original Android Development] coloxim:
OK...4 cores is better in performance but mpdecision is more equilibrate battery/performance....

OK...OK...talk later with facts...

;p
[Nexus 4 Original Android Development] lyfkevin:
[MENTION=3750240]stratosk[/MENTION], Will you consider to add limiting the number of cpu to 1 when screen off?

Thanks for your simple but very useful works:thumbup:

Hey I have a problem with battery drain..AGAIN! My battery drained over night abnormally, over 20%. In BBS paerial wakelock was audioout_2. I resolved that with installing an old version of viber. After that,the phone was working almost 2 days without problem. Then anothe problem occurred.. Yesterday,I charged my phone to max, killed wifi,cleared RAm,did the fast reboot.. Over the night it used 34% of battery!!! In BBS, partial wakelock it said baseband_xmm power! How can I fix that?

I have to say, this JB sucks! This never happened on ICS...:mad:
[LG Optimus 4X HD] Flying_Bear:
It seems to be tegra3 issue that randomly pops up. I've found no solution yet
[LG Optimus 4X HD] xtribas:
i got this wakelock too, factory reset did not solve it
[LG Optimus 4X HD] brunek:
When I woke up and so the wakelock, I just rebooted the phone and the wakelock was gone,and so far it is not a problem anymore...:confused: But I still dont know what caused that...
[LG Optimus 4X HD] umut.t:
I keep having this problem as well. Rebooting temporarily fixes it but it comes back after a while. A solution would be much appreciated.
[LG Optimus 4X HD] MatthewFox:
Same for me guys, I would like to add that I'm using the Zaiben ROM; are you using that too?

The reboot didn't fix the problem on my phone :(

im using portuguese 20A, and i can´t get rid of this damn wakelock, sometimes it goes away with a reboot, but eventually comes back...
[LG Optimus 4X HD] archie87:
I'm on Asia 20A with the same problem. 26% lost overnight. Not good at all. In ICS it was like 6% overnight, lol.
[LG Optimus 4X HD] future81:
Dunno but in official bootloader unlock thread it needs you to be connected to real network for some time then I would say there's a way to monitor that time and maybe this is it - maybe it disappears after bootloader unlock
[LG Optimus 4X HD] xtribas:
my bootloader is unlocked
[LG Optimus 4X HD] brunek:
My baseband_xmm_power wakelock is showed in kernel wakelocks but in partial wakelocks there isnt any wakelock worth mentioning.. But over the day,when i turn wifi on and do a reboot it doesnt show at all..:confused:

Thats my biggest problem,it shows up randomly...
[LG Optimus 4X HD] momothecat:
I have the same issue, 6.6%/h battery drain last night. And the big problem is baseband_xmm_power. I check my wife phone (not tegra device) and "baseband.." not even in the kernel wakelock. I read somewhere (forgot the site) it's tegra kernel problem, and after they install custom kernel the problem with baseband is gone.

I'm not developer but I wish lg will release kernel source now, so somebody can optimize the kernel asap :D
[LG Optimus 4X HD] MatthewFox:
Mine's unlocked too.
[LG Optimus 4X HD] ming0000:
me too, battery drain 20% more overnight, cause by baseband_xmm_power kernal wakelock, 6h 20m. :rolleyes:

is that JellyBean 4.1.2 got bug?
[LG Optimus 4X HD] archie87:
It seems to affect a lot of the Tegra 3 devices, however, I owned two Optimus G's (they're not Tegra 3) and they both had issues with battery drain too and it also had to do with the baseband. I surely hope my next LG, which may be the Optimus G Pro, doesn't have these issues.

erm, really problem for this issue, hope that can settle.

[Nexus 4 Q&A, Help & Troubleshooting] strongtyer:
I am having the exact same issue. That almost makes me think it could be a software issue but you said you already did a factory reset.

The weird thing is that it looks like the same part of the screen. Its a horizontal section in the very middle.

My best conclusions are that its the digitizer. It just started happening out of no where though. Very frustrating. Makes it impossible to hit the send button on the stock messaging app without minimizing the keyboard! I take excellent care of my Nexus 4. It has a case and it hasn't been dropped. It hardly has a scratch on it! Its a month old.
[Nexus 4 Q&A, Help & Troubleshooting] kazzarok:
Strongertyer I can feel your frustration.

Here's mine (the one in my op was found from google). Mine is a bit lower, it blocks the top half of the qwer line on the keyboard and the yes/no buttons on prompt windows.

I can still type qwer just fine by pressing the bottom half of the keys, but for the the prompts I have to tilt and rotate the screen every time so the buttons aren't under the "dead zone".

Strongtyer are you also thinking of sending the phone back to Google?
[Nexus 4 Q&A, Help & Troubleshooting] strongtyer:
Just talked to support and they seemed helpful. However, his first suggestion was to do a factory reset of course. He said if that didn't work then I could send my phone back for a replacement. Did a factory reset and still the same issue. Looks like I'll be calling again tomorrow.

I guess the plus side is that they send brand new phones and not just refurbished ones.

Any luck on your end?
[Nexus 4 Q&A, Help & Troubleshooting] kazzarok:
I gave up fixing it already as you can see in my 2nd post and I believe it is not possible to fix it other than having the whole screen replaced, so I asked directly for a replacement under warranty. Then after a brief moment google emailed me a set of instructions for packing the phone.

So on Sunday evening I booked the courier, printed the documents, picked everything back in the box, warped and taped it. And today the courier came and collected my phone.

Now I have to use my good old HTC Legend again. However it uses regular SIM card, so I had a bit of fun making myself an adapter to up size the Nexus 4's micro-sim!
[Nexus 4 Q&A, Help & Troubleshooting] strongtyer:
I talked to Google today and they are sending me a replacement. They told me I can keep the phone till the new one arrives. I just have to return it within 21 days. :)

Just crossing my fingers that they don't say the damage is my fault. I don't know how o could have caused it. I haven't does it and I take really good care of it.

Could it be this problem only happens with the newer phone's? I have the one with the little feet on the back. Version 605 I thought. What version do you guys have?

Also should I unroot and lock the boot loader when I send it in for repair ?even though the problem has nothing to do with it.

[Nexus 4 Q&A, Help & Troubleshooting] stevemw:
Welcome to xda-developers. Your English is fine.

You should contact Google.

Interesting that you mention the newer version of the phone -- I'd be interested in knowing if this is in fact a result of a newer manufacturing process, different materials, or maybe the place of manufacture (Korea or China). The place of manufacture can be identified by the letter in the fourth position of the serial number found on the box.

I have the same problem but mine is like 2 inches from the bottom of the screen. I can use the softkeys in portrait but they are unusable in landscape. I have had the phone since Nov 12 so sadly my phone is now out of warranty. LG's approved repair centre want £95 for a new screen. I am thinking maybe buy a Nexus 5 and trade this in for £70. I could sell it for like £130 but I would feel bad selling a phone I know the screen is on its last legs.

This "kinda" works for me, you could try it

I have a Nexus 4 for about 2 months. I have this problem since I got it (not new) with a section on the right side, from the top to bottom. Last night was the first time I fully charged my phone through USB port on my laptop, let it untouched all night. Today I was super-excited to notice that my screen proplem disappeared. Well, after 9-10 hours, it reappeared. I'm charging it in the same way right now and I can hardly wait tomorrow to see if it happens again. Someone on another forum affirmed that his phone completely repaired doing this. I'll come back with an update.

Update: I confirm this really Works. After another night while charging through USB, my phone had the problem in the morning and I decided to draw to share my section. Just 1 minute later after saving the screenshot it started working perfectly. I have two screenshots now, one with problem, one without it. I tried to post them, but I'm new here and I'm not able to upload things.

(I hope my English is good enough for you to understand)
[Nexus 4 Q&A, Help & Troubleshooting] rip9150:
hey, so am i understanding right that you charged your phone with your laptop and it corrected itself? i have an lg g2 and i have this same problem. it wouldnt be as big of an issue if it didnt break my knock on.
[Nexus 4 Q&A, Help & Troubleshooting] veketash:
Yes

Yes, I'm charging it through USB port since I posted this and my screen is fully functional and works like a charm :) I recommend this to others.

But be a little patient, the problem will reappear after the first time when it dissapears, but after that it will progressively improve. Hope you'll resolve it.

I'm afraid to charge it by using the wall charger now, I'm thinking that could be a current problem, thus means that USB charging current is a lot lower that the outlet.

Does anybody know the amperage of a laptop's USB port? Why not just use a wall charger with the same amperage?

[Nexus 4 Q&A, Help & Troubleshooting] veketash:
This is a good idea, I was thinking about that. I do have a cable to extend the original one and when I connected that to wall my phone said something like "73% Charging (USB)" and the amperage was quite lower, although my phone was connected to the wall charger with that extension cable.
