Power button to turn screen on after sleeping for a while, to pattern lock screen. Everything lags about 5-15s behind for the first minute or so. Perfectly fine with on demand, shows up all the time with interactive and msm

I noticed this too

I was on MSM governor when this happened. I am now on interactive and there is a slight lag on wakeup. I will try on demand for the next 24 hours and compare.

Hi there,
I'm happy to see you here

And I have a problem: With this kernel LBE crashes as soon as it gets root permissions. Is this doomkernel related?

POWER1FM · Mar 2, 2013

With on demand/deadline no problems so far (since yesterday).

I am 99% certain it is not kernel related, but i dnt know what LBE.

I have the stock kernel packaged with TWRP right now installed (TWRP updated to latest version with goomanager).

Flashing this kernel zip in TWRP will override it with cwm right?

I don't know why some kernels have TWRP and some cwm, what is the better recovery? Changing it every time will make problems with the backups right? or can we cross restore?

dont worry i will be implementing multi-recovery system in subsequent releases... u can choose which recovery u want while booting

this is only an initial release

yes. thank you very much.

it is the first kernel that I flash with recovery. so there won't be any problems if I have twrp? cause while installing your kernel, the recovery will be overwritten right?

There is something I never understood, and it may be a stupid question but: ¿why are kernels tied to a specific rom?.
I mean, given that we often flash kernels and roms independently, one would thing that they are somewhat disconnected.

I'm asking this because DooMKernel looks good enough to make me ponder between staying on AOKP with its custom features, or switching back to stock to be able to enjoy this kernel.

it is possible that a kernel supports more roms but now we have a jb kernel and cm10 for example (and aokp 4.1 too I think) uses ics kernel. maybe we get some kernels that support stock jb and cm10.1 but we have no fully working cm10.1 for now.

most changes are only related to ramdisk... if the custom ROM works on stock ramdisk then u can use my kernel on that ROM...

but ROMs like CyanogenMod require a different kernel.. as there are CM specific changes in the kernel stock based kernels wont work on CM and vice-versa...

Arcano · Mar 3, 2013

Thank you both for your answer. I've never developed for Android, so terms like ramdisk are a bit fuzzy to me; I'll have to read some more.

I guess "porting" a kernel to work on a CM-based rom is not trivial then, right?. (I'm not asking for a port).

Works perfect on my T

Hi,

Since I have changed the governor back to on demand I have absolutely no lag on wakeup. I have also OC back to 1.89 (I previously throttled back because of the lag). Using deadline for the schedular, I have tested anything else there.

I have not tested backups, I dont see there being an issue with it, but if someone has time and could take a backup then restore it, it would be nice to know...

Greg I don't know about you but I've noticed since the JB update from sony, always when you change a governor or the I/O after some time you'll experience lag, sometimes horrible sometimes bearable but it is solved by a reboot.

i've been testing interactive, ondemand and msm-dcvs with cfq I/O is the combinationt that works best for me.
Always reboot after changing governor or I/O on JB, that's my recommendation

Kernel is really awesome, beginning from the nice bootlogo to the performance. did not try other governors but ondemand with 1728 MHz is really fast, no bugs at all.

thanks for your kernel, we can hope that you continue this nice work

and so you guys say flash kernel user SetCPU to put it to 1728 and ondemand...and the lowest value ??

and also how is the battery?

Try it yourself and see what works best for you and your phone...

what do you use as ur lowest value?
