[KERNEL] Kernel (deprimed_test) - Break It If You Can

[rancur3p1c]

Currently using the latest kernel with latest MIUI rom. For me working great, no lag what so ever. Also experiencing music skips and stuttering, making it almost impossible to listen to music on phone but don't believe kernel related as have had trouble in past. I believe it is ROM, music player, and lack of RAM on og Droid related.

Music skipping may be kernel related. I have that issue when using prime kernel not when using stock ProjectElite kernel. It seems to not be happening as frequently once I thought to turn off the "turn up sd card speed" back to 2048 (default) from 4096 (I think that was the setting). It's less than it used to be and doesn't bother me anymore.

I can try to find the issue but it's definitely rom related, what ROM suffers the worst lag?

I've noticed it with Liquid's rom the most. CM nightlies/stable seem to have little to no screen wake lag. It's hit or miss with certain roms. Reading back through some of your changelog updates there was something about a hidden feature (something to that effect?) that makes the phone go into a deeper sleep. Could that be why it takes so long for the phone to wake?

I've missed the entire duration of phone calls ringing because it takes that long for the screen to wake up. Once the screen is awake then the phone flies like usual. This is with standard voltage and even with increasing the minimum clock speed, doesn't help it a bit. lastly, there is never any lag when turning off the screen only when turning it on.

edit: also note that in my experience when the phone is charging/plugged in there is no screen wake up delay but as soon as it's pulled of the charger and you turn off the screen it will lag real bad from then on every time the screen wakes. Also doesn't matter which governor either ondemand, bumblebee, interactive all of the above, same delay

When this happens please check the load averages, either with setcpu or manually by issuing the command 'busybox uptime' and post the three load averages.

They look something like:

0.36 0.10 0.06

But I'm willing to to bet yours will be more like:

11.45 6.43 1.68

What does that show, mine comes up 0.8, 1.93, 0.8. Are those good numbers?

this is what I got

edit: the high number values were after the screen was off for a few minutes. after the screen comes on the numbers go back down in time.

I have an update coming, the overclock module does not seem to like the updated android ndk and has held me up.

I will compile a test build for those of you who aren't on CM, I will leave out the overclock module for the test until I get it working properly again. Check back in 20/30 minutes for testing.

The lag your describing is caused by the high time in states, the system is getting behind for some reason and can't wake properly as the cpu is not responding correctly.

 

[bstealthy]

Awesome, look forward to testing

Compiling now, had to find and download my go to ndk revision of r4, r7 is broken as far as I'm concerned.

Test this and let me know if it's better please, seems ok on my device but I'm on cm.

Fixed overclock and primed commands, same URL.

Could'nt get past boot animation on your lastest test kernel running latest MIUI rom. Tried multiple times rebooting as well as clearing cache. No go for me.

 

[cms5423]

Runs unbelievably well!

 

[bstealthy]

Gave the newest test here a shot and it still has the same result, still has a long delay waking up

We're you previously running a custom 20overclock? If so download and try again as it may have still been active, I fixed the msocv variables and reuploaded.

I am at a loss, I reverted BFS and changed to deadline which is what I figured was the issue.

 

[KJW979]

No wasn't running anything custom. But did reflash & got it to boot up. Was a little laggy at first but seems to be picking up steam. Will test more in am to let settle in as 5am will be here sooner than later.
