I've been looking at my logcat and I'm constantly getting the error

"PowerHal-Error opening sys/devices/system/CPU/cpufreq/interactive/boostpulse: no such file or directory".

What is this and is it something to be concerned about? It shows up when touching the screen.

Thank you, I see that my lowest one is 384 MHz/850mV so if I want to apply a -100uv do I have to set that for every step? Or just subtract 100 from the lowest one

Re: [KERNEL][GPL][N4] franco.Kernel - r95

Can confirm that the freezing is due to the interactive governor... Seems to be stuck on one core at the lowest frequency... Screen off/on brought it back to normal..

Re: [KERNEL][GPL][N4] franco.Kernel - r95

My issue with 95 is when I wake the phone and unlock it, it's stutters for a few seconds then is nice and smooth.
[Nexus 4 Original Android Development] benblb:
I had an issue with r93 and r95 that I did not have with r86. I just restored r86 to test. When I try to unlock the phone, a lot of the time it pulls down the notification bar instead, which tends to be quite frustrating. It also happens when accessing the camera from the lock screen. I don't want to stay on r86 though since r93 and r95 and smoother. Stock Android 4.2.2. Thanks for the continued improvement, Franco!

EDIT: This does not only happen on the lock screen. Other screens too. Back on r95 because of the smoothness.
[Nexus 4 Original Android Development] Tunderpimp:
Wake problem

Not to sure if this is whats causing my problem at the moment, its small, and started when I flash the newest nightly #95. When I push the button on the side of my phone and it wakes the lock screen is real glitchy. I ran cool tools and the cpu went from around 300 something to 1500. It went glitchy at the spike.

My first last_kmsg, is before I flashed my back up, and then flashed #95. Now since I've reflashed it happens a lot less, but still happens.

another thing I've noticed was on boot it takes longer for the kernel to gain super user.

[Nexus 4 Original Android Development] lonelysheep:
Re: [KERNEL][GPL][N4] franco.Kernel - r95

The phone lag sometime in r95, it might because sometime when the phone is just wakeup it only has one CPU plug in and it is load 100% but don't know why the second CPU does not plug in. Additionally is it new that only one CPU is used in idle? I remember previous it was using two CPUs in idle?

I am using xylon 2.2.1 nightly 61

Re: [KERNEL][GPL][N4] franco.Kernel - r95

I'm liking r95 so far but using interactive with highspeed freq set to 1188 instead of conservative (over my 4 hours use, found it to be near the upper end of CPU frequencies compared to interactive. Same stuff that I would be normally doing when on interactive, thus draining my battery a bit more while on conservative). No lags using march 2nd build of PA. Even when on 1188, smooth so far, no lags, no uv'ing
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
Is there some reason why there's so much discussion about conservative governor for r95? Is it just because Interactive is not behaving like the old hotplug method in r93 and previous versions?

Edit: Ok, see that franco's personal choice is conservative... lol. It's tough to catch up because ever since that post there's been like 7-8 pages of posts.... and I'm on 50 posts per page....

Re: [KERNEL][GPL][N4] franco.Kernel - r95

I thought interactive was working fine for me too until I went to to unlock a couple time really quickly after turning on the screen and get the 10 sec of lag. I haven't gotten this with conservative. Maybe it's different for everybody though.
[Nexus 4 Original Android Development] sucre213:
There is definitely a problem with r95, stock r95 doesn't change anything,

occasionally, the phone wake up pretty slowly and the cpu stuck at single core 384MHZ and the phone became very laggy

yesterday I thought it was coincidence, but today it happened again. Hope you can figure it out, franco.

Thanks for your hard work by the way..

Re: [KERNEL][GPL][N4] franco.Kernel - r95

Undervolting will not increase battery life significantly. It helps make your CPU cooler thus it uses less power which can save battery power but not much. Try undervolting up to -75mV or lower it according to your CPU bin.

[Nexus 4 Original Android Development] snickerpop:
I'll have to check to see if that happens next time. Though I think the problem might be because I don't have a direct connect. I connected to a extension cord that connected a surge protector. Usually it charges, but that's when I am not using my phone.

Your charger also charges with a higher current than USB. I don't think it will damage anything.

[Nexus 4 Original Android Development] death5023:
Very noob question over here. My battery life has been horrendous and one of my friends suggested I try another kernel out so....

I just rooted my phone my using the toolkit. Then I downloaded and moved the zip kernel to the N4. After, I went into recovery mode and just selected the kernel. Is that all I had to do?

Thank you
[Nexus 4 Original Android Development] ctfrommn:
If by selected you mean installed, then yes. You can confirm the kernel you have installed by going to about phone and looking at the kernel version.
[Nexus 4 Original Android Development] mjehan:
would also like to know. do i need to install Franco's app and set a specific governor & I/O schedule... or does the kernel have it all programmed inside ?
[Nexus 4 Original Android Development] ctfrommn:
Just install and go. If you have no cpu controlling apps installed it should default to Franco's settings of 384/1512 Interactive.

I had the same problem then all of a sudden. It disappeared, try tinkering with your set up of chargers with usb cables. I'm honestly not sure how I fixed it. I just tinkered with my combos, got it to charge ac and then used stock charger and cable and now it's always changing ac

Just a little status update for all wondering:

With the official (!) usb charger, my Nexus 4 just booted up.

Thanks Franco
[Nexus 4 Original Android Development] franciscofranco:
Well by default it comes with 200ms sampling_time, which means it takes a lot of time between freqs and takes a lot of time to decide to go up or down. The only thing I did was to decrease that so that it is more responsive while making the decisions. Ondemand and Conservative are like twin brothers, 90% alike, Ondemand ramps mostly between min/max, conservative goes from 1 freq to the next without jumping (at least in its default behaviour, its possible to make it more even more aggressive).

Re: [KERNEL][GPL][N4] franco.Kernel - r96

R96 is running as smooth as r95 was, maybe a little faster. Will check for battery life if I won't be flashing a new rel tomorrow! Lol
[Nexus 4 Original Android Development] DesertVelo:
Agreed... and like any good testing, only change one variable at a time to isolate the problem. Changing to a new kernel *and* a new nightly ROM just makes things too difficult to find a good baseline for reference. Cannot *blame* the kernel if you have updated the ROM as well. Yes, it is hard not to flash the latest and greatest...

BTW, looks like Jenkins is building M2 tonight. Good time to freeze the ROM for kernel feedback!

Quick question, maybe not related but maybe you guys can help. Which one uses more battery, one online core at 702 or two online cores at 384? Assuming thermal effect is neglegible since running at relatively low freq. And assuming 384x2=702 even it is not, but u get the idea. :confused:

I had to revert to r93, the screen was too unresponsive. For instance, when scrolling in stock browser, it would take finger too far a distance for app to actually begin scrolling the view. Felt like I needed to drag the finger over almost half a screen before the web page started scrolling. It did help if I pressed harder, but much too hard for comfortable use that I'm used to.

Another issue I had was a bit choppy homescreen scrolling.

Guys although I agree searching does make the whole thing better, answer them when it doesnt cause you much trouble and you have decided to press the "reply" button

its nothing about a bricked phone. I think for that kmsg your phone did not auto reboot directly into the bootanimation. instead it crashed completely and you hard reset it. Then maybe TWRP worked something in between and its last_kmsg has replaced the previous last_kmsg from your system crash. dont worry about it, its just one less informative kmsg (for franco) and thats all.
