The latest faux kernel 30u r2 overclocks the gpu to 450 which holds fine in the fauxkernel enhancement settings and gives blazing fast 3d scores in antutu.... I'm thinking maybe 450mhz is the max for the gpu? dunno whether 500mhz is worth trying?
[Nexus 4 Original Android Development] _Sparks:
So if this kernel is undervolted by default then how can I go back to normal?

Also what are the implications of undervolting?
[Nexus 4 Original Android Development] arffrhn:
I have read somewhere in bricked kernel thread that gpu peaks out at 450, more than that is just a waste of power. So I guess yeah, 450 is the max for gpu.

Edit: Found it.

Use trickster to restore voltage to normal. Your phone will shut down and reboot. Google undervolting for more info. Kernel runs fine at the lower level

[Nexus 4 Original Android Development] Reed-Sternberg:
Sure, admittedly this particular occasion was with very light usage (no gaming (I never do), video calling, or gps use). And I have excellent T-Mobile LTE coverage at home (even though I'm connected to Wi-Fi)

Having said that: I use ART(noticed that using ART, no manner how much I UC, the UI stays smooth). UC to 1026000, scheduler to row, governor to wheatley, didn't touch UV except for the 1026000 khz to 875000. Use greenify to hibernate some of my background apps (all VOIP apps use a lot of battery).

That's it. I'm still experimenting to find the sweet spot. With my normal usage I get 48 hours and 4hrs SOT. 5% drain over night (connected and all sync on), 8% drain in the morning streaming Google music while using endomondo running tracker for 1hr.

Good luck!

That was me that guy was talking too and im pretty sure he's wrong, its not that the GPU can't handle OC above 450 its just that 487 is the only one that has been made to work

Check out some of the older discussion in the trinity thread (or any other big kernel thread out there). They've gotten it up to 522 but there is absolutely no performance boost after 487. It just burns through more power. If you think that's wrong, maybe try and build your own and show all the kernel devs the error of their ways?

Announcement!!

I discovered the reason behind screen flickering on nexus 4 Kitkat. (Hopefully)

I used FauxClock app to enable C1 sleep state (retention)

Screenshot:

Once I switched it on screen flickering started to occur. The second I switched it off the flickering was gone. I repeated the process over and over to be sure, always with the same result. Tested with Purity 4.4.2 + Hells-Core b43 T2 KK

So C1 sleep state causes screen flickering

To switch it off you either have to use FauxClock App, or use this terminal command

su
echo 0 > /sys/module/pm_8x60/modes/cpu0/retention/idle_enabled

Cheers.

LOL people always asking for updates and thinking that just flashing or making a newer version of something always means its better. If what you have is working fine for you and cures all your needs then why update just for the sake of updating. Now if there are new additions and a real good reason to update then go for it..

Lets be honest when math makes a kernel he normally does it right the first time and is that not what we want from our developers... Keep up the good work math and sorry that you did it right the first time... LOL

Happy New Years peeps :D :good:

Can anyone suggest a good widget overlay that will show me what speed my GPU is running at in real time?

I know you can see a bar graph from developer options but that is not what I am looking for. I want to see how my GPU MHz speed changes as I do various UI stuff.

I have searched the play store but can't find an overlay that includes the GPU. Plenty for CPU but not GPU.

Cheers and happy new year to all.
[Nexus 4 Original Android Development] dunni88:
Agreed, I used to be a bit of a Crack-Flasher (BTW ouside of XDA that would put quite the odd image in someone's head). After a few years of it, I've found that that the latest isn't always the best. The more things that get changed, the more chance there is for trouble.

It really depends on the dev though. Some of them, Like Mathkid, seem to be very thorough and not release until they have something truly better.

I flashed it over PSX 3.0.5 ROM to try and see if I could get any more battery life out of my phone. Too early to tell for sure but it seems to be improved. There is one thing that I really, really miss from PSK (the kernel that is packaged with PSX). That is the BUNDI screen calibration. It just makes the screen look so much better. Colors are true and vibrant, whites are white and blacks are black. Pretty good. I know you can set it without using the LCD color preset option in Trickster. But that is the only fast and free way that I know how to do it.

Does anyone else really want Bundi or any other presets? Or am I alone?

Hello to mathkid and all members. I have a strange problem with KK: when I switch wifi often (using Greenpower) the wifi switch dies. Then i can't turn it on again until reboot. It dies after about 2 days of toggling every 30 minutes.

I know that it's not this kernels issue, but mathkid already surprised me couple of times. Can this be solved by the kernel?
[Nexus 4 Original Android Development] justvarshney:
Hi Mathkid, I use your kernel and also trying to compile it for USB-OTG patch. I have noticed that you have reverted the kexec support from your kernel. Is there any specific reason for that ? would it be possible to add it again ?

If not, would you permit me to add the kexec support & USB-OTG support for users who like to use these features ?

Appreciate your response.

Would like to ask if this rate of msm_hsic_host wakelock is normal for this kernel?
[Nexus 4 Original Android Development] Dan1234567890:
That wakelock is connected to your signal strength...so if there was weak signal, and phone was searching for it or switching from 2g to 3g or so, this wakelock results in bigger percentage.

So it is not kernel related. :thumbup:
[Nexus 4 Original Android Development] SweetPant:
Really? I searched about msm_hsic_host and found that, at least, kernel plays a part in it. Even the changelog of this kernel has mentioned something about this wakelock. However I was on wifi the entire time and had data off. I check the battery status and see the mobile network signal green most of the time. Mobile signal on statusbar is full (4 bars) at the moment too.

PS. don't get me wrong. I'm not blaming this kernel. I actually love it though. Just want to know if other people are facing it.

Upstream versions have a few fixed stuff, yeah, but the problem is that if you merge upstream changes, it merges codes that are not used at all, so that actually may slowdown kernel sometimes.

Nexus S was back when I had a different car. Funny enough, that one did Bluetooth audio streaming, so I didn't even have to worry about USB. Even then, UMS still worked before 4.x days, so I wouldn't have had to try to do this through OTG.
