Flashing twice seems to help also. I have yet to experience the CPU 1 issue, so I'm really unsure if its source related or something else. I installed sense xp and kernel at same time after a full wipe and I've had zero issues so far.
[HTC Rezound] HowardZ:
I find that all versions after the 4/10 version will eventually turn off the second cpu.

That's one way to save battery :)
[HTC Rezound] lukester01:
Installing twice fixed it.

Maybe because I'm s-on?
[HTC Rezound] pirateNati0n:
Seems like that option's been in the MP-Decision for a while. Anyway, definitely liking the latest build with my screen on/off profiles.
[HTC Rezound] crazymoron010:
I'm currently trying a full wipe, 4/20 is my birthday build so lets hope it works :D
[HTC Rezound] HowardZ:
Pirate,

I meant the problem where the 2nd cpu totally disappears from the kernel tuner cpu display. Nothing can get the cpu back into operation.

This condition eventually will happen on my Rezound with all versions later than 4/10.
[HTC Rezound] iHateWebOS:
Evo3d users are having the same issues with new versions of kernel tuner. I might give some older versions a try.

Here's all the older versions

http://goo.im/devs/pedja1/kerneltuner
[HTC Rezound] winston856:
Here we go, flashing 4/20!

coming from 4/5

Wiped dalvik and flashed twice. Now my CPU 1 is gone in kernel tuner.

Also just tried a few older versions of kernel tuner. While those would actually let me adjust the second core, it always defaulted to off or KT crashed. Going to flash 4/18 to attempt regaining of the second core.
[HTC Rezound] power950:
Hearing all the problems with the CPU 1 disappearing I'm staying on 4/16 until its all straightened out never had that problem yet but don't want to
[HTC Rezound] pirateNati0n:
Yeah my problem with no CPU1 was never eventual. It was always immediate. I thought you were referring to the option for single core when the screen is off.

If KT was the one causing the problem it should go away with a uninstall and reboot right? I would test it with a benchmark app to see if it reflects a difference without KT installed.
[HTC Rezound] Jonman409:
Almost sounds like a hotplug issue
[HTC Rezound] iHateWebOS:
This one is tough for me to test, since I don't experience this issue myself. Please try flashing twice, to see if this helps.
[HTC Rezound] winston856:
Flashing twice proved ineffective for me, Decided to stay with 4/10(03) for now.
[HTC Rezound] lepa71:
How can I restore original voltage?
[HTC Rezound] Tidewater:
Just throwing my two cents in here. I have been running every version of this awesome kernel and have tested them all with both KT and trickster and have never lost Cpu1.

Sent from AOKP thanks to thebroken and ihatewebos
[HTC Rezound] lepa71:
Can somebody confirm if you were under-volting when CPU1 was not showing up? I'm on the INFECTION 2.4 and if I under-volt I would loose second CPU.
[HTC Rezound] highdro:
Same here. Happy 4/20!!!!!!
[HTC Rezound] HowardZ:
I saved the voltages from the 4/7 version, and always use them with the newer versions. The 4/7 voltages are higher for better stability.
[HTC Rezound] iHateWebOS:
This cpu1 issue really bothers me, especially considering i cant test fixes prior to release. What really bugs me is that 4/20 undervolted -50 is working amazing for me @ the moment. I need to re create this bug before i even know where to look.
[HTC Rezound] redduc900:
It's working great for me too on CM10.1. I think the problem is with Kernel Tuner, as I haven't had any problems since using System Tuner Pro instead.
[HTC Rezound] power950:
I just flashed the 4/20 build and no problems yet my CPU 1 isn't disappearing hasn't yet and don't think it will
[HTC Rezound] highdro:
I wonder if all these people with issues have really old rezounds or refurbished ones because I've always used kernel tuner and tried trickster as well and all is good for me. Mine isn't even a year old yet and I haven't had any issues out of mine.
[HTC Rezound] HowardZ:
Try making a kernel tuner profile.

Then apply settings from the profile, exit kernel tuner, start kernel tuner, look at cpu screen.
[HTC Rezound] pirateNati0n:
That didn't fix it for me when I was having the problem.
[HTC Rezound] winston856:
To add to this discussion, falling back to an older version of KT (4.2.1) didn't solve the issue for me either.

Maybe I should try one that's older still?
[HTC Rezound] iHateWebOS:
I use 4.0, can anyone help me recreate this issue? There has to be something that triggers this bug.
[HTC Rezound] HowardZ:
I should have been more clear. This seems to be a way to cause the CPU1 problem
[HTC Rezound] iHateWebOS:
I got ya, I tried this earlier several times with a profile to change frequency to 1728, gov to badass and voltage to -25. Didn't lose CPU 1 yet. I'm about to sit and look at this for a bit and see if any thing sticks out.
[HTC Rezound] HowardZ:
Ihatewebos,

Perhaps the CPU1 problem has to do with my kernel tuner settings?

Both cpus 192 to 1512 using Badass governor.

Gpu 2D 200, 3D 266

Fast charge Off

OTG Off

VSYNC On

32 bit color

3 or 5 percent button back lighting

IO scheduler ZEN

Notification light timeout Never

SD Card cache 256

Using latest cyanogenmod 10.1 version

Regards

Howard

I also use the kernel tuner 4x4 widget and set it to update every minute

IF I TURN OFF THE SCREEN, WAIT A MINUTE, AND TURN THE SCREEN BACK On, then CPU1 is off, and will not start up again unless I reboot.
[HTC Rezound] iHateWebOS:
OK so I have gotten a few boot loops from leaving kernel tuner installed and flashing a new kernel (I usually un install this between flashes). What's making me think it's kernel tuner is that when stuck in a boot loop, a simple wipe of just the data partition got me booted again....
[HTC Rezound] HowardZ:
I think I found a way to prevent the CPU1 problem.

In kernel tuner, mp decision,

Set threshold down load = 0

I just discovered that with this set to zero, one can not reboot as the boot animation goes on forever.

I restored a nandroid backup made yesterday.

Nevertheless, before the reboot it seemed to prevent the CPU1 being gone. It appears to me that when mp decision turns off the CPU1, then it never gets turned back on, except by rebooting.
[HTC Rezound] md303:
There's a setting in Tuner to revert to kernel defaults when a new kernel is flashed. I haven't tried that yet though.
[HTC Rezound] RebelShadow:
Kernel is running great for cept for one issue. When I go into kernel tuner then mp-decision and try to change the idle frequency from 384 to 192 and click apply the change does not stick and reverts to 384. Is there something I'm doing wrong or is there a lock on it?
[HTC Rezound] HowardZ:
Okay, here is something else I found.

Mp precision settings to default except add a zero to pause, =100000

Now CPU1 will not disappear from kernel tuner cpu screen.

However I still think cpu1 is offline too much and antutu benchmark is lower compared to the 4/10 HIRO.
[HTC Rezound] manchucka:
Interesting. When I do this only cpu0 shows up in KT. Reverting setting doesn't bring cpu1 back. I'll see if a reboot helps...

UPDATE:

Reboot brought back cpu1, but assigned to it minmax governor.

Return of stock plus, this way you have a guaranteed stable alternative.

Only changes made to this kernel are:

# Reduced RAM footprint of android logger

# FauxSound-TPA (works great for me)

# Enabled KSM

# Implemented Con Kolivas patch set (for better responsiveness)

# Updated Qdsp6 to version 3(better call quality)

# Zram enabled by default

Edit: if you still have CPU 1 issues, then this problem must not be kernel related.
[HTC Rezound] twich12:
latest cm10.1

i have the latest of wildstangs cm10.1 and the kernel will not flash I'm s-on and using the latest twrp. I go through the install process but it stays with wildstangs kernel... ideas?

edit: nevermind I switch to amonra and it flashed... strange. I'm not sure if it was because I switched to amonra or if it was because I did a reboot-bootloader and let the image update (I figured it would update when reboot after recovery but maybe not)
[HTC Rezound] crazymoron010:
So I did a clean install of the 4/20 build and it seems that after i change the governor to lulzactive as long as i don't mess with anything else in kernel tuner it won't make my cpu1 disappear but once i try changing the the cpu min down from 384 to 192 it caused cpu1 to disappear when i exited out of the cpu screen and went back in it was gone. Also, no issues with cpu1 disappearing on stock+. Is there anything I can do to help figure out what the issue is, since your phone doesn't seem to replicate the problem?
[HTC Rezound] HowardZ:
Yes crazy,

I think you are right. Keeping min cpu speed at 384 seems to prevent losing cpu1.

I'll see how it goes the rest of the day goes.

Good catch,

Howard
[HTC Rezound] RebelShadow:
Confirmed, did the same for me.
[HTC Rezound] crazymoron010:
So if you go into voltages and bump up the 192mhz voltage to 825 you can now set the min frequency to 192 without losing a processor core. Also @ihwos I noticed in the voltages that it has a 310mhz frequency but we can't set our min to 310 just 192 and 384. So i think the 310 frequency is unused?
[HTC Rezound] Deathbyfugu:
Just wanted to say that the update to the Qualcomm DSP that you included makes a HUGE difference. Call quality is now as good as the stock Sense 3.6 ROM. Thanks a lot. BTW I am using the 4/20 build with 384 as my min and 1512 max, OnDemand and Noop and everything is working perfectly with Stang's 4/20 build (I did a full wipe and fresh install).
[HTC Rezound] HowardZ:
Crazy,

Once again you are correct.

But, in the case of my Rezound the magic 192 mhz voltage needs to be 850.
[HTC Rezound] drynyks:
Which completely defeats the purpose of using it (192)
[HTC Rezound] king.james:
IHate, Do you have any plans for the next RC stable with all of the new tweaks? Or are you still working for the test kernels...

Thank for all the hard work and awesome kernels.
[HTC Rezound] lepa71:
Just want to report that using 825V for 192 solved 2nd core issues.

btw. What is the default voltage table for Rezound with original HTC sense?
[HTC Rezound] SynisterWolf:
question:

Ive noticed my phone while charging on AC is getting slower now. Do you think this could be a kernel issue? im on the 4/20 release.

EDIT:

Ok so after i toggled 4g off so i can see if it was draining more that i was charging my phone went from 81% to 100% and i have a green light. -_-
[HTC Rezound] brenuga:
For some reason, activating USB debugging to PC can introduce lag into phone, go figure. If I get a call while plugged in, there is a 1-2 second delay between start of ring and screen turning on. Suspect its some thing to do with adb, as it gets worse after I've been using adb push to test files.
[HTC Rezound] crazymoron010:
Has anyone gotten USB otg to work? I just got a cable today and have been attempting to mount a flash drive with no luck.

Edit: Found cpu1 bug and squashed it.
[HTC Rezound] lepa71:
What was the bug? Just curious.
[HTC Rezound] iHateWebOS:
It wasn't voltage it was mp mpdecision. Parameters for MP in acpu_clk source was structured for a min of 384, so when you used settings outside of those parameters it would cause conflict. I wasn't experiencing the issue myself because I never change my min frequency settings.
[HTC Rezound] power950:
Does the 4/20 test build still have that problem? Nvm I just did it

The 4/20 build does, but the 4/25 does not.

The stock+ build in the OP was updated 4/25. It's actually pretty smooth using the interactive governor. Stable as it gets.
[HTC Rezound] power950:
Does the 4/20 and 4/25 support faux sound I was on 4/20 and bought it and I'm changing gain and presets ect and nothing is happening so I updated to 4/25 and same thing :/
[HTC Rezound] iHateWebOS:
Yes they both support faux sound control. Don't forget to close and clear all open music or video apps, since the settings don't apply instantly. I personally Set on boot and restart my phone to apply settings.
[HTC Rezound] king.james:
Not to be stupid, but how does one control and use the faux sound option? Is that a command or something other?

Thanks
[HTC Rezound] Tidewater:
There is an app for control in the market. Search faux123 and it will come up. If you set it on boot and use the jazz presets for everything it really sounds good. Clean sound with great bass, especially when coupled with awesome beats 5.
[HTC Rezound] torr310:
Thank you OP for this awesome kernel!

I tried version 4/20 without problem. I am on 4/25 now, it seems fine too.

I never notice the aforementioned core issue as I don't know how to check.

Just being curious to run benchmarks for 4/25.

Quaddrant score: 3384 or 3409

But have problem running Antutu, I tried 3 times and it jumps out of the screen in the middle of the test.

An interesting test to me is the stability test inside Antutu, did anyone do the comparison? Even compared to other devices?

S-Off, Infection 2.3 Slim Edition
[HTC Rezound] iHateWebOS:
Stability test makes the phone extremely hot and takes like 5 minutes to complete. I quit half way through out of lack of patience.
[HTC Rezound] winston856:
Battery life is back baby! 4/25 is the ****! The min is also back where it should be at 192.
[HTC Rezound] nimbice:
4/25 build is bootlooping me. Tried wiping cache and dalvik to no effect. Redownloaded and reflashed it also to no effect. Going to try a full wipe and reload back to Infection 2.4 dev (it's what im running now) with 4/25 and see if that helps. Maybe something I had set in Kernel Tuner with a previous build is allergic to this one?

I'll let you know how it turns out in the event someone else finds themselves in my shoes. In which case I'll beat them up and take my shoes back. Jerk. I'll have to disinfect those now...

Update: That seems to have done it. I'm back on the air with 4/25 on Infection 2.4 dev inverted. Now please leave my damn shoes alone.
[HTC Rezound] iHateWebOS:
I typically uninstall kernel tuner between kernel flashes, just in case.
[HTC Rezound] power950:
When you flash a new kernel does the voltage reset I don't uninstall kernel tuner and I was on 4/20 undervolted by 50 then I flashed 4/25
[HTC Rezound] iHateWebOS:
You have to manually set default voltages or perform full wipe to reset voltages
[HTC Rezound] torr310:
I am on 4/25 and my Google Now disappeared. I had few reboots before, there are two times it asked me to enter setup: choose Language and my First/Last name for the device.
[HTC Rezound] iHateWebOS:
I've had that happen on all aosp kernels. Never had Google now disappear though so, I'm not really sure why yours did.
[HTC Rezound] nimbice:
Never occurred to me that it could be an issue. I'll put that on my checklist next time around.
[HTC Rezound] iHateWebOS:
It's how I managed to recreate the cpu1 bug. I had kernel tuner set to min 192 then flashed 4/20 build without wiping. A little while after that booted up I lost CPU 1

small clean up of some Zcache typos and that's it. I have 4/28 ready which has a few more changes and the latest Linux 3.0.75 upstream
[HTC Rezound] Snuzzo:
Similar to that. I can make it a static script (/sdcard/sonboot) which will work with SM, or I can do a script that can be ran anywhere on storage but not compatible with SM.

[HTC Rezound] iHateWebOS:
I have removed that feature due to stability issues.

Kernel samepage merging combines identical memory pages from multiple processes into one copy. The process increases CPU usage though so it's benefits are questionable.

I'm at 15 hours at 50% with Stangs rom + latest test 4/28 on Mugen 1900 battery. I don't know if that's good but it's great for me as I am usually at 9 to 10 hours at 50%. Settings are as follows using latest Kernel Tuner.

Both cores set at Lulzactive 192 to 1512

I don't know what the stock voltage is as I have always undervolted on a custom kernel since having the phone but at 192 my voltage is 725mV. I just hit "all -12.5mV" till I hit 725.

Idle Freq. at 192, Screen-off freq. 192 and single core at screen off

GPU 2d at 200 and 3D at 300

Backlight at 33% fastcharge turned on, row scheduler, sd card cache at 256, and S2W off.

That's pretty much it.
[HTC Rezound] Luke1213:
similiar to mine. i use lulzactive and SIO, button light off, fastcharge off. question: does Fastcharge really make a difference? i hardly feel it so i turn that off in case it makes charging even slower. how does it work in practise? thx
[HTC Rezound] iHateWebOS:
Fast charge makes USB ports charge at a/c speeds. However it's currently not compatible with usb2.0 ..... Well problem with that is almost all USB ports are USB 2.0
[HTC Rezound] md303:
My phone is frequently plugged into various USB2.0 devices and I usually get ~900 mAh charge rate :D Only my work laptop "officially" supports fastcharge on USB 2.0
[HTC Rezound] RebelShadow:
I get anywhere from 900 to 1200 MA when plugged into my 2.1A USB lighter plug. Fast charge is a must for me as I regularly use GPS guidance while streaming online radio. With fast charge I can stay ahead of the game and also fully charge the phone in under 2 hours.
[HTC Rezound] HowardZ:
From what I have read, when a phone is plugged into a computer the phone reduces the charging rate so that it will not blow out and destroy the usb in the computer.

The new usb 3 can provide more current and can handle the faster charging rate the phone uses when plugged into a wall charger.

So, when plugged into a computer with usb 3, turn on fast charging.

When plugged into a computer with usb 2, keep fast charging off to prevent damaging the computer.

When plugged into a wall charger or a typical car charger, it does not matter if you turn fast charging on or off. It will not make any difference.

Fast charging is only applicable when charging from a computer's usb ports. The only exception might be some strange wall charger or car charger which somehow appears to the phone as being a computer.

[HTC Rezound] manchucka:
Thanks for your continued work.

Question: with 192MHz and 384MHz both running at 825mV, is there any reason to run at 192MHz at all?

Honest question, not trolling.

? ?
[HTC Rezound] iHateWebOS:
Nope :thumbup:
[HTC Rezound] manchucka:
Thanks for the quick response.

Follow-up questions: if we set our lowest frequency to 384MHz, what effect does this have, if any, on "idle frequency" and "screen-off frequency", both of which are set to 192MHz in MP-Decision? Would these effectively change to the higher frequency, or would they be ignored, and thus no longer impose their otherwise desired limits?
