Is deadline the recommended IO scheduler for general launcher/app use (non-gaming etc)?

What voltage tweaks have you guys had success with (Using FKU app)?

300Mhz for example is 800mV, anyone gone lower without instability?

Same for 2265MHz, 1075mV, anyone gone lower without experiencing instability?

Oh and also, in general, since the CPU is so amazing, for completely non-gaming use, would you guys recommend lowering the max CPU frequency (in the interest of improved battery life?) and if so, what value without compromising speed and responsiveness in launcher/general apps?

Thanks in advance.
[Nexus 5 Original Android Development] akaHardison:
I recommended ROW(Read over write).Enable Fsync if you want stable.

UV to 650mv at 300mhz.PSV 4 CPU.

UC to 14xxmhz.GPU to 320MHz.

Make your pre-app profile many software like tapatalk doesn't need too high frequency.
[Nexus 5 Original Android Development] paradoxiumwind:
Thanks. What's "PSV 4 CPU."?

Also, if I set these settings to enable on boot, and they turn out to be unstable, how do I turn it off so I can get back in to the ROM and change it again?

Holding volume up and down when the device powered up(google has been show).System will go to safe boot.Clear app data or click in app and disabled on boot option.

Add edit:don't try to push too hard on voltage.Maybe you can use your device without reset.But it will get more app crash(Weird,same problem on bricked).

PSV 4 I had tried to use 635mv on 300,it work fine in faux,and franco r32.But r33 can't hold it.If I turn off screen and want to wake up again.I have to wait for about 30 second....
[Nexus 5 Original Android Development] mattcooper:
Been getting a tonne of launcher redraws since r33. Never experienced it before... Could be a complete fluke, but I don't know if could be caused by a kernel? Any chance someone could chime in? Cheers :)
[Nexus 5 Original Android Development] paradoxiumwind:
Thanks. I got this:

This is after applying the voltage / freq. settings the other guy told me, and restarting.

So.. what does it mean?
[Nexus 5 Original Android Development] :
Wanted to add that I'm also experiencing audio issues on r33, as soon as I press play music stutters because its switching the right earphone off and on and then refuses to play from the right one, only the left one works, I played music at loudest volume, first time I've encountered this issue

Headphone volume boost = 4

Headset gain boost = 1

I've attached a bug report zip generated from Slimcenter after the issue happened
[Nexus 5 Original Android Development] alanwyl:
It means your CPU is not working properly with those settings.
[Nexus 5 Original Android Development] gee2012:
You undervolted too much, i`am on PVS 2 and i can undervolt -50 max, it instantly reboots on -75.
[Nexus 5 Original Android Development] ironjon:
Yeesssssss, same here with PVS 2 :p
[Nexus 5 Original Android Development] bobby janow:
Downloaded the latest FKU, went to change color profile and reboot. Here is the log. I did have the camera running at the time.
[Nexus 5 Original Android Development] paradoxiumwind:
So should I check the PSV before undervolting to check it?

I'm changing settings in the FKU, simply things like usb fast charge, and turning on 'enable on boot', but the settings aren't saving after restarting my phone - any ideas??
[Nexus 5 Original Android Development] Tzfardaya:
The point is its a camera apk issue, not a kernel issue...

Which is whyvibsaid navigate away from the page, then go back... Your profile will now be there... All thats happening is the page isn't refreshing but the profile is being created...

Not a kernel issue (usually) grab the kmesg and logcat next time...

---------- Post added at 08:57 AM ---------- Previous post was at 08:53 AM ----------

Find your own uv settings by testing for yourself... A good way is to drop global by another 25 each day until you get glitches... Then raise global back up by 25...

It usually takes a few minutes for fku to trigger and change the set on boot settings... Wait until you see the granting fku root access before checking the app...
[Nexus 5 Original Android Development] bobby janow:
I do get that. But before it didn't seem as if the camera bug affected the device as much.. it recovered. Now once the memory gets sucked up the rest of the programs suffer and I would venture to guess the battery life too. Until Google fixes it, if they ever do, I'll just reboot after using the camera which is a royal pain but worth it.
[Nexus 5 Original Android Development] franciscofranco:
Small bug already fixed on my local build. I changed too much code to be more modular for me and some pieces were broken in the process. Glad its a beta :)

Because the code has changed. I'll probably increase the threshold a bit for r34.

Can you repost it please?

No log?

What menu? If you mean the drawer then you're using a pirate version. That is blocked on the latest production release though.

It shouldn't get hot at all if its down to 960MHz. Can you get me some kernel logs plz?
[Nexus 5 Original Android Development] matesc:
sure :)

Here is the original post with the description:

and logs are attached.

Thank you very much!
[Nexus 5 Original Android Development] sasho36:
What I mean is when on the Manage page (and my profiles are there), if I want to save the in the saved_per_app_modes folder (so I can import them after clearing FKU data), nothing happens when I click Save, they aren't exported to the folder.

Edit : I just red Franco's post and it will be fixed in the next build...
[Nexus 5 Original Android Development] bigmem:
Sorry to be a major noob :( which logs will help and how do i capture them, i'll recreate the reboot and get them for you
[Nexus 5 Original Android Development] Tzfardaya:
And you haven't been reading mine.... Save the profile as normal, navigate away from that page (stay in the app), then head back to that page again... It is being saved, there's just no refresh call (which is what Franco had said, and will be adding in the next beta)
[Nexus 5 Original Android Development] Triversity:
Sure thing. I got you 2 last_kmsg. Let me know if you need further information.

[Nexus 5 Original Android Development] sasho36:
Yes, I've read it and I'm aware of the refreshing problem. I know how to save them but I can't make a backup. When I click "backup modes" on the Manage page, nothing happens.

I've changed my system language to English so I can use the right words, sorry for the confusion but it wasn't translated well in French. "Backup modes" is "Sauvegarde des modes" in French and not "Modes de sauvegarde". Hope is clear now.
[Nexus 5 Original Android Development] gee2012:
That would be last_kmsg.txt and logcat.txt, look on Google please how to make them.
[Nexus 5 Original Android Development] Tzfardaya:
My apologies, I was working around the wrong problem... It's unfortunate there were so many per app issues with the recent betas... Nor was I picking up on any language clues that you weren't working in English... My fault. All clear now. :P
[Nexus 5 Original Android Development] jayakumar6591:
After flashing this kernel it show a clock speed speed of 3.01ghz ......though reducing it to 2.2ghz .the cpu-z and geekbench 3 shows 3.01ghz with benchmark of 1780 MC

pls help me guys !
[Nexus 5 Original Android Development] paradoxiumwind:
Since I tried undervolting/underclocking, none of my settings are saving. The only things that are saving are the 'persist through reboot' icon changes, but the actual setting relative to them does not save. I have tried stopping the app and wiping all the data, rebooting and doing it again, but the same thing.. any ideas?
[Nexus 5 Original Android Development] gee2012:
It means the kernel can be clocked up to 3 Ghz, its not showing the actual speed you have chosen.
[Nexus 5 Original Android Development] Tzfardaya:
Are waiting until you get the toast shoeing fku is granted root priv?
[Nexus 5 Original Android Development] paradoxiumwind:
It happens instantly as soon as I run the FKU.
[Nexus 5 Original Android Development] jayakumar6591:
any comments on benchmark?

cuz my stock kernel scores 2500...the phone is okay!!! but does this happens to everyone
[Nexus 5 Original Android Development] Bill Gamble:
Are you greenifying f.Ku? Don't.
[Nexus 5 Original Android Development] gee2012:
Everyone has this, it shows the maximal clock speed archievable with this kernel.
[Nexus 5 Original Android Development] paradoxiumwind:
Damnit. ES Task Manager told it not to run at startup. Sorry guys. Sorted now.
[Nexus 5 Original Android Development] Tzfardaya:
After you reboot, leave the phone until you get the toast showing fku has been granted root priv... It may a minute or so... After you get that, then check if your settings are being applied...

Fku doesn't change the settings from default until after the system has fully booted... Showing the launcher is not an indication of the phone being fully booted...
[Nexus 5 Original Android Development] franciscofranco:
Because you might want to set specific settings on a Per-app basis but the file does not list in the creation panel coming next FKU it will be possible to add custom paths. So for example instead of "please franco add input_boost_freq to the PerAppModes creation list" you'll be able to add them yourselves. Possibly in the future a way to easily import paths from other users. This will make the interface even more powerful than before.
[Nexus 5 Original Android Development] Tzfardaya:
So let me see if I'm reading this right... The per app module will also have a shell script (file) launcher? We can add a bunch of echos in a file and per app will run that script? Ooooohhhh, nice....
[Nexus 5 Original Android Development] franciscofranco:
Nope. Much easier. You'll be able to add custom paths to the list of already available tunables you can set on a per-app basis. Something like this:

Currently:

max cpu

min cpu

governor

bla bla

bla bla bla

You want to set something in a per-app basis, imagine io scheduler (just for the sake of the example). There will be a new panel where you click "Add a custom path", then opens a dialog with two fields "name" "file path". Then you write "I/O scheduler" and "/sys/block/mmcblk0/queue/scheduler". Hit save and the next time you try to create a new PerAppMode you'll see a I/O scheduler option and you can write your custom value. Something like this:

max cpu

min cpu

governor

bla bla

bla bla bla

I/O scheduler
[Nexus 5 Original Android Development] Tzfardaya:
Ooooohhhh even better! I wantz nao! :P

Me too, but I haven't finished yet ;)
[Nexus 5 Original Android Development] rashad360:
Thanks so much Franco for all your work on this kernel. The battery life increase when I switched to it was amazing. I used to struggle to get 19 hours life with 2 hour screen time and now I can go over 33 hours with 3 hour screen time. Thanks for bringing out all of the potential of the N5, it is like a whole new phone.

Has anyone noticed problems with headphone volume? When listening to music, mine drops to about half as loud every few minutes. Weird.

Or is that a feature to protect my poor ears?
[Nexus 5 Original Android Development] semcosweeper:
Sorry guys I've never had fku crash so I have no experience with logcats but I grabbed one after the most recent. Tell me how or where to send it, whether here or an email address to Franco and I will. I used catlog to grab it.Running most recent fku beta.

I have had it happen 4 times in a row even after a reboot. To reproduce, open per app modes, I have a profile for benchmark and tap edit. Change CPU temp threshold and tap save. At this point it crashes every time.

Guys this is an off topic question but can I flash Viper 4 Android sound mod with r33..I will disable the headphone boost from FKU ..will it still cause any troubles ? .. Thanks
[Nexus 5 Original Android Development] OptimusVDarwin:
Try it for yourself and see if it works
[Nexus 5 Original Android Development] whitedragonz83:
I wanted to bring in my observations about Android and RAM usage as a few have brought up things in regards to r33.

I've been running stock kernel (and stock ROM) for about a week without rebooting and observed the following (seen in the default Android RAM usage monitor):

1) Initially I'll have ~650-850MB used

2) Occasionally I'll see it spike to 1.2-1.4GB used for what appears to be "no reason" as in, it isn't a running or cached app, but the space to the far left that appears.

3) Occasionally I'll see a return to ~650-850MB RAM used

4) Camera app pulls in extra RAM beyond normal apps, maybe similar to a game (~300MB more) and it appears to be added to the far left area of RAM usage (not running or cached app)

Summary:

RAM usage will fluctuate significantly, but appears to always eventually returns to near boot-up levels.

Again this is on stock. Since only a few people are reporting "issues" on Franco r33, I assume they are witnessing the times that Android spikes the RAM usage for no reason. If you want to "clear it" either A) wait and it'll eventually return to normal; B) reboot the device.

As a test, just don't reboot your device and see if a day later (especially after either a charge or idle time) it returns to 'normal levels'.

TL;DR

Enjoy your device with Franco Kernel! "Flash and Forget" the Franco moto!
[Nexus 5 Original Android Development] JNewms:
False. The kernel has absolutely nothing to do with the runtime. I'm using it with 33. No problems with it at all
[Nexus 5 Original Android Development] CDeviant:
This is my RAM after 67 hours on r33, the home screen, and chrome close all the time :/
[Nexus 5 Original Android Development] Red5:
Runtime (ART) dosent interact with the kernel, thats all ROM/software based.
[Nexus 5 Original Android Development] franciscofranco:
I've just seen the crash log on my console, thanks :)

[Nexus 5 Original Android Development] OptimusVDarwin:
Lol am I doing something wrong franco?
[Nexus 5 Original Android Development] Kimy Hardy:
i've got that issue since r33, r32 works bettah
[Nexus 5 Original Android Development] big_adventure:
Works beautifully for me.
[Nexus 5 Original Android Development] JNewms:
If you're looking for ART support, this isn't the place for it. I'm not sure you will find a place for it though, since it is still in It's experimental stage.
[Nexus 5 Original Android Development] OptimusVDarwin:
Well ART worked on the previous versions so that y I'm a lil confused
[Nexus 5 Original Android Development] JNewms:
Understood, which is why I told you that the kernel doesn't affect ART at all.
[Nexus 5 Original Android Development] Tzfardaya:
Are you on the latest version? Sounds like issues from one of yesterday's betas...

Works fine on SlimKat + Franco R33 (was Cata + R33, but was ok there too).

Note: no Exposed in the mix.
[Nexus 5 Original Android Development] OptimusVDarwin:
Uninstalled exposed and it worked. I just love being hard headed
[Nexus 5 Original Android Development] Tzfardaya:
So test it, show us the results on stock, r32, and r33
[Nexus 5 Original Android Development] TrenchKato:
I have to respectfully disagree with you. While your observations about the stock kernel are correct, The behavior with r33 is not. I have also been running weeks worth of test and when the RAM usage spikes it is not being released ever. This renders multitasking and some streaming apps useless. Having to reboot 3 times a day has become slightly annoying.

Neither the stock kernel nor r32 behave this way with the exact same setup. At this point I feel like legitimate concerns are simply being ignored because others are not having the problem.

I love Franco's work very much and have been using it since the Galaxy Nexus. But I may be forced to switch kernels.
[Nexus 5 Original Android Development] Batfink33:
I have to say, I agree with you. R33 is very glitchy for me. I have a lot of launcher redraws and after a while I find the phone virtually unusable. I flashed back to R32 and everything is fine.
[Nexus 5 Original Android Development] GeekMcLeod:
Just tested it myself, and I had no issues at all.

[Nexus 5 Original Android Development] bobloadmire:

[Nexus 5 Original Android Development] Testraindrop:
Hmm 80 hours uptime and 0.9Gb RAM used here... Seems normal to me.

BTW. Kitkat offers a visualization of RAM usage in the development settings.

Did you know that Nova uses 100mb, whatsapp 60 and beautiful widgets 80mb?

At least on my device...

[Nexus 5 Original Android Development] Batfink33:
Yeah, a lot of Ram is used for Nova etc, it this is only happening to me withR33, R32 it doesn't happen at all. I also tested another kernel and had absolutely no redraws.
[Nexus 5 Original Android Development] akaHardison:
So there are many people saying r33 is very unstable.Why not try to increase your voltage a bit(if you undervoltage).I have undervoltage too much(635mv on 300mhz,worked fine in r33beta and faux).So I got a lot crash.Maybe uv will make bus,ram,nand unstable.So data goes wrong.
[Nexus 5 Original Android Development] GeekMcLeod:
I don't have any issues at all with Nova. Have you tried with the aggressive desktop option? I don't use it but it says it'll help with redraws.

If I knew how to help since I don't have the issue, I would.

[Nexus 5 Original Android Development] Batfink33:
OK, I've got voltages on stock and havent had any redraws or problems so far, so maybe that was the problem.
[Nexus 5 Original Android Development] Tzfardaya:
It's less an issue of not believing you guys, but more of, if we can't replicate, we really can't debug much...

You say that 32 and 33 act different wrt ram...

What is your per app usage in 32 and 33, which ones are larger, are there more apps using the ram longer in 33

[MENTION=4164775]TrenchKato[/MENTION], you say you've been running weeks worth of tests on 33, but 33 has only been out for about 3 days...

33 spent a long time in beta because there were memory leaks... are you sure you're on r33 and not one of the test 33's? reflash using the fku autoupdate section and test again

[MENTION=748911]batfink[/MENTION], [MENTION=4741842]xXghostXx313[/MENTION], what apps do you use before the launcher starts redrawing? How long after reboot does it take before the launcher starts redrawing?

[MENTION=4741842]xXghostXx313[/MENTION], I find chrome to redraws like that even after a fresh reboot and only chrome launched... I think it's a problem with the way chrome was coded...

at everyone... give me some scenarios to test that you think indicate memory leaks, I will compare r33 to r32 and stock... I don't mind... may take a couple days for me to get the time to, but I will test....
[Nexus 5 Original Android Development] fcisco13:
Using nova on purity, absolutely no problems, zero issues, no redraws. Amazing kernel.

Oh yes there is a problem, don't know where i left my phone charger, hardly use it.

Whatchu talking bout willis!
[Nexus 5 Original Android Development] mikeacela:
I have had no issues or instabilities on r33. Im using the stock kernel settings and am not undervolting. Everything is smooth to me, my battery has lasted 48 hours with moderate use. I actually lost my charger 2 days ago and didn't realize till today when I needed it. So far i find r33 to be an improvement over r32 despite what some say. Purity rom.
[Nexus 5 Original Android Development] Tzfardaya:
[MENTION=3292224]franciscofranco[/MENTION], might need to add to the OP "If experiencing any issues while undervolting, test with stock voltages before reporting issues"

UV seems to cause more problems than it solves.. :P but it is nice to have the option to use it.
[Nexus 5 Original Android Development] GeekMcLeod:
Been using r33 since its been out of testing and I also haven't had any issues. I used to think I had a ram issue, but it was just gravitybox's stupid ram in recents. When I looked in settings, it was about 400mb higher.

Difference between us is, I am not even close to stock. PA B6 with 9 xposed modules and those dakvik bionic, or whatever, patches.
