I have been reading this thread for almost 20 min., getting updated with all the improvements u have been doing. I think it is simply amazing the way u work. U are responsible, u keep doing development, u recieve critics, u answer questions and u fix problems, this is what we should expect of every developer. Simply thanks, this kernel is amazing.
[G2 Android Development] varund7726:
Where do i find that in synapse?
[G2 Android Development] :
Does the Lollipop build have the kexec patch? Just wondering, because when I get my new screen, I might try running some self-compiled builds of LS 4.0, PA 5.0, and CM 12.
[G2 Android Development] pestjay:
what setting do you use? i got poor battery on 802 ?

thanks
[G2 Android Development] fma965:
Actually you shouldn't expect anything from "every developer" they do it cuz they want to not cuz they have to.
[G2 Android Development] albsat:
I tried the new governor, but the phone got too hot and I had audio issues. Running cm 12. Went back to ondemand and all is OK.
[G2 Android Development] gasReal:
hi guys, can I use this kernel on 20H stock?
[G2 Android Development] enr88:
No.only Aosp and Lollipop cm12 based ROM. Read Op.
[G2 Android Development] sheikhramnuj:
can i use this with slimkat rom? Thanks!
[G2 Android Development] bps119:
You can use the kk version on slim. Not the lollipop version.
[G2 Android Development] Choristav:
...it got stuck, didn't it?

I was testing settings, set the input boost freq to 960MHz for all cores, then fiddled around with sync threshold (1190->1728>1574) and now it seems the first core got stuck. I'm using the intellimm governor with cpu multicore power saving.

Anything I could provide you to figure it out?
[G2 Android Development] sheikhramnuj:
I flashed the kitkat version on slimkat but result in a bootloop. :(
[G2 Android Development] TDSJR:
That's because Slim is based on 4.2 sources.
[G2 Android Development] RenderBroken:
It should go below. I have an idea why but it looked to have been fixed. Its weird that it is happening to you. R3 is the one I fixed it in so re-flash it and let me know. Thanks for the report!

I use simple_ondemand to save battery but you are right. For now I would us the msm_adreno-tz. You will get better performance out of this without staying at 450mhz. When I merge in my GPU patches that add more freq steps simple ondemand will work better.

Thanks! Yea, not all devs are like me. But it does seem that the ways of the prick devs are slowly going away. But this relationship works two ways. I am as helpful as I can be as long as the users to their due diligence. Meaning at least search before asking and be respectful. If you ask a stupid question, expect a stupid answer and move on, laugh at it. Thanks for the kind words!

Under the CPU Tab, look for Input Boost Freq. There are 4 of them since I added that you can set it per core.

No, did you use it with the KK Kernel?

Yea it is still brand new. I wanted to try it out but it needs to be optimized.

I would just use a different governor. It may not play quite well enough yet. Thanks!
[G2 Android Development] zetsumeikuro:
[MENTION=221618]ReNDeR[/MENTION] thanks for the response! Quick question about the thermal, I moved the temps up so it wouldnt throttle so quickly. Even with the first throttle set to 70 i notice at 65 my cpu gets knocked down to 1.5? VS980 any ideas? Thank you.
[G2 Android Development] RenderBroken:
No the way it works is:

65 - 71 = 1.5GHz

72 - 78 = 960MHz

79 - 84 = 300MHz

So if you want it to not throttle as soon, you need to move both temp thresholds.
[G2 Android Development] zetsumeikuro:
Strange. I changed phase 1 low low to 70 and allowed high to 75 and adjusted the the frequency to 1.7 vs 1.5. I adjusted phase 2 and 3 accordingly as well, but instead of 1.7 it hits 1.5. Maybe I have a setting incorrect? Thanks again!

Just want to chime in that I used to get at least 5 SOD's a day on default cm12, and haven't gotten a single on on R2 or R3!
[G2 Android Development] ledvedder:

[G2 Android Development] RenderBroken:
Well have you applied the settings? It will do that till you have hit the check mark denoting that you accept.

Serious crashes and restarts with [MENTION=4662457]Rashed97[/MENTION] Cm12 11/28 build paired with the Render R3. Anyone confirm? Everything builds and works as expected. Flashing the kernel starts the chaos. Would be interested in answers from all variants.

Cheers, J
[G2 Android Development] RenderBroken:
Apparently that have been some recent changes in the new build that make things jacked up. I will take a look tomorrow to update my own kernel to accommodate.
[G2 Android Development] J:
Thanks for the heads up man.

[G2 Android Development] brianmoyano:
Hey, whats up? Can somebody share good synapse configs? And also i would want to know which temperatures are right for the phone. Thanks.
[G2 Android Development] rmsinaga:
Default kernel setting is good. Playing around with the parameters will help you understand the effects. No harm to try. You can start with just changing the governor & scheduler without changing the parameters in it to see the impacts.
[G2 Android Development] Quiox:
I had reboots on AICP 11/29 with R3 also. VS980.
[G2 Android Development] MBurns2:
Thnaks render, last r3 for android L is working great on latest liquid smooth build..
[G2 Android Development] HueyT:
All AOSP 5.0 roms are based off of CM12 so R3 will need updating to be compatible with latest CM12 commits
[G2 Android Development] RenderBroken:
Yea I have confirmed that I just need to update my ramdisk. I will do so later today and release again.
[G2 Android Development] sheikhramnuj:
Yes! This kernel works now in my LG G2 D802 with slimkat rom stable 8.0 Anyone here who wants to share their profile for extended battery life? Big thanks to you [MENTION=5438598]RenderBroken[/MENTION] ;)

[G2 Android Development] GibonXL:
Any more KK love?

Hi Render,

I am a fan of THE KERNEL and enjoy it very much. Battery life on my D802 with LS Milestone is getting better than ever:good:

However, had one SOD and sent You the logs.

I know we are here for fun, but I can't join the Lolipop party, my aosp and THE KERNEL powered D802 is a working horse, a daily driver, not a toy. Could You be so kind and let me know, if I can provide You with any additional information to help?

Also, if I touch Synapse/ADV tab and change anything beginning with C, the phone freezes.

RenderBroken, please pimp the R25 :p

Edit:

Although understand the rush for 5.0, I am waiting for the things to settle up a bit.

Every week will bring new commits and the need for upgrading ramdisk and other stuff. After changes in the sources new changes in the kernel. It's fun, but some people, like me, just can;t join the party and still want to hang on AOSP lol
[G2 Android Development] RenderBroken:
I took a look at the logs and there isn't anything in there to suggest the kernel screwed up or something. Most likely it was a kernel settings that was changed. What changes did you make?
[G2 Android Development] RenderBroken:
Building r4 now

GPU bringup - OC and such

Fast Charge Bringup

[G2 Android Development] jamesd1085:
Waiting for this issue to be resolved to give it another go on mahdi...no disrespect to Mahdi's kernel as it gives me 100% of what I need but I love trying out what's out there and at least giving it an extended testing to see which gives me better balance of performance/battery life!
[G2 Android Development] fix-this!:
Battery life is still top notch here with aicp. Did have a couple lockups though. Might be undervolted to much.
[G2 Android Development] BlakeSm:
0 reboots so far on R2 D800 7-09 Mahdi.
[G2 Android Development] 1ceb0x:
0 reboots on mahdi 7/7 + r2 since I flashed them on 7th of July. I suggest anyone that reports reboots to try the updated Mahdi ROM. on 28/7 I also had random reboots and those can also be attributed to the ROM. let's not burden render with a problem that might not be a problem in the end. kernel runs awesome on my d802 with mahdi 7/7. I even have art enabled. cheers!
[G2 Android Development] Raagh:
Reboots are present with 28/7 7/7 and 9/7 with render kernel but not with stock.

render is amazing despite the reboots.
[G2 Android Development] RenderBroken:
Hmm. . . I just recently updated to the 7/09 build and have noticed the same behavior missing. We can keep an eye on it still. Thanks bother!
[G2 Android Development] Raagh:
Just to be sure i ll make a clean install of 7/09 tomorrow and flash render kernel to make another test :). Then ll report
[G2 Android Development] 1ceb0x:
idk mate. I have no reboots in 5 days and I use my phone all the time because I have no laptop nor PC. maybe because I installed the kernel on top of the ROM at the flash - wipe cache, data, dalvik, flash ROM, flash patch, flash gapps, flash render, reboot and set up.

no issues...I don't know what to say.. they might also be related to your carrier, to your modem, apps, so many variables....
[G2 Android Development] mikereidis:
Thanks. :)

I'll be happy if you can just get the FM code patches in, and at some future time, add the FM sound flag into another defconfig or 2.

I'll do the FM testing. Beyond getting that done I can't make any other commitments, unless it's related to the FM.

Yes to family; I have "one" job, these Spirit FM apps, and that often gets to 60-70 hour weeks; at least no commute, and I'm in the house when the wife or kids need me.
[G2 Android Development] 1ceb0x:
are you a radio spokesman? :) that's awesome!
[G2 Android Development] simon_lefisch:
Clean installed mahdi 07/09 and flashed Render at time of install and had 1 random reboot. Been good since then tho, so the reboots can happen whether flashing kernel at time of flashing ROM or after installing ROM.
[G2 Android Development] 1ceb0x:
thanks for confirming. I was just merely suggesting what I did and I have no reboots. glad to see that for you is stable as well. I must say I didn't touched this kernel's settings and everything is stock as Render releases them :).
[G2 Android Development] simon_lefisch:
Same here. All stock settings except for read ahead buffer (3072) and scheduler (deadline). Gov still on interactive, no over clock.
[G2 Android Development] 1ceb0x:
what exactly do you gain with that enormous read ahead buffer?
[G2 Android Development] simon_lefisch:
Higher read speeds when accessing files like pics/video/etc. Think of like ram but for a HD. If you consistently access files like the above mentioned, having them in a buffer allows for faster accessibility. Therefore load time is quicker.
[G2 Android Development] 1ceb0x:
well I know the theory but I mean.. is it that noticeable? :D
[G2 Android Development] simon_lefisch:
I notice a slightly better performance when loading vids and pics. I'm just trying out 3072. I typically stay at 2048 as I feel there isn't much of a difference past that.

Hi [MENTION=5438598]RenderBroken[/MENTION]! Do you think the battery drain issue [MENTION=3664961]lastest[/MENTION] CM12 alpha is kernel related or rom related? Will R4 fix it! Thank you!
[G2 Android Development] RenderBroken:
Did you have battery drainage with My Android L kernel? Also nothing changed in the latest CM12 kernel except the ramdisk. So I would say its Rom related.
[G2 Android Development] J:
I was getting the best battery life i had seen thus far with any L build with the R3 setup. This was on a variation of the CM12 Builds from [MENTION=4662457]Rashed97[/MENTION] & Crew. Just update the Ramdisk and touch nothing eles. ;)

[G2 Android Development] anbinhv:
Thank you [MENTION=5438598]RenderBroken[/MENTION]!

I never have any battery problem with R3. I use stock kernel because lastest CM12 not compatible with R3. So I don't know if the stock kernel cause the problem or the rom does. I hope that the stock kernel cause that and when I flash R4 the problem will go away.

1 more noob question, I think I'll go back to the previous CM12 build, will R4 compatible with older CM12 build.
[G2 Android Development] RenderBroken:
No it will not work backwards. I am close to finishing R4 right now.

Something came up and I dont have time to build and upload 6 kernels right now. I will do so when I wake up. That will give me time to test R4 anyways Goodnite folks.
[G2 Android Development] GibonXL:
First things first, the logs were taken directly after sod. The phone rang and the display didn't turn up, led was working.

LS Milestone + R25, dalvik, no xposed., latest supersu.

In synapse gpu set to 320, cpu clock to 1,9, the rest was "stock" with bacon governer.

I took R25 on board straight after release and all was ok for a few days, until 28.11, when the sod happened and I sent the logs.

And now a completely diffrent story after sod.

When I go to synapse/adv and in krait c-states untick any setting with C, my D802 freezes.

R25 has default settings now, didn't touch anything after reboots. I'm waiting to see what comes after a few days of usage.
[G2 Android Development] RenderBroken:
Interesting. yea I wouldnt mess with the c states, I would not undo the ones that are checked. That is literally how deep the sleep is when it is idle. If you take that away I would imagine it would crap out. Yea try the stock settings and let me know.

Obviously your setting is the root cause. Powersave governor will lock phone CPU clock speed to the lowest allowable frequency, which is 300MHz. Use other governor such as intelliactive, interactive, ondemand to have smoother experience.
[G2 Android Development] TDSJR:
Probably the combo of Power Saver, ondemand & underclocking. That profile is too conservative. I'd switch profile to default, and then under clock to 1.9.

I am getting irritated to hell with this new CM12 build so I am going to revert all changes and it will essentially just be R3 but will work for the newer CM12 builds.

No, if you don't apply the settings after opening synapse the first time, there will not be any issues caused by it being installed it doesn't auto apply the settings, it requires you on them first.

Also for cleanliness of this thread, if you have a question, please note what build you are on, what android version, and what rom. This will help sift through the thread so I don't have to open another one just for my lollipop kernel. Thanks guys.

Hi render, yesterday I experienced SOD after >100h up time. When I tried to save the logcat (dmesg or last_kmsg), it only captured the events after I restarted (long pressing of power button), so I couldn't find any clue about the SOD root cause. Any idea how to capture the logcat if in case another SOD in the future? I wonder what happened.

My settings: D802, Mahdi ROM 2.9 10/27, R25 kernel, Intelliactive & Zen, min/max freq 249/2263MHz, no UV, other settings unchanged from default.

Many thanks :thumbup:
[G2 Android Development] nfin1te:
Dont report SODs unless you are using 300mhz as min. Freq. (also, no UV). There _can_ be stability issues if you don't, cos every SoC is different. May work, may not work. :)

This has been stated several times before.

[G2 Android Development] RenderBroken:
Yea, it very well could be the min freq you are using. No other settings changed?

Thanks, you are absolutely correct.

I have not had any crazy battery drainage using my own kernel. I will be building R4 shortly for all variants. Give it a shot and let me know.

Also guys, we really have to work hard at keeping this thread organized somehow. This means when reporting any issue, you need to specify the Android build, Rom version/date, and Kernel used. Do this first thing before writing about your problem.

<example>

Android 5.0 / CM12 11/29 / R3

I had experienced and SoD. blah blah blah :)

</example>

This way we can easily see what you are referring to. There are a metric ton of awesome ppl in the thread that are more than willing to help but wasting time to find out info that should be easily available clutters the the thread. I say this as not someone how is pointing fingers or is upset. I am just trying to get ahead of the curve. I love development. If I didn't I would not have built for Android L so early. I like discussions as well. This is a thread where I like to teach and learn as well. I imagine that CM12/Android L Roms will change at a VERY fast pace. I will work to keep up. Thanks guys

[G2 Android Development] Choristav:
d802/d806 here, i'm still on the latest available liquidsmooth build for the d802 which is dated 26/11, it doesn't seem to work with R4.

For me it boots just fine, but freezes after about 15 seconds and instantly reboots. I have reverted to default settings by using the check icon in synapse (which indeed restored all the original settings), but it still reboots.

If it's intended then please disregard this post and wait for a newer LS build.

Meanwhile I'll try flashing the kernel again. Should I even try to post the logs?

Reflashing did nothing and syslog output empty 0kb files as there's a very narrow window to get the logs before the reboot.

Ramdisk was updated to support the newest cm changes, the 11/26 version likely isn't up-to-date enough, try flashing r3 instead
