Bliss did not boot with this kernel either but aicp mm did
[G2 Original Android Development] PsychoGame:
Hello [MENTION=2494120]syrkles[/MENTION] and [MENTION=5122725]vrwmiaris1[/MENTION]

I'm not familiar with RR or Bliss at all.

Are these Roms directly based/build from CM kernel and device source tree?

If not this kernel is not meant for the rom in question.

Also can you tell me which devices you have?

Nice to hear AICP MM is booting, I'm guessing this rom source is directly based of CM sourcetree

Before using this kernel, i am facing some extreme lag from time to time even after clean install, but this kernel seems to solve this issue, great work!
[G2 Original Android Development] Lawlrus:
[MENTION=4647521]PsychoGame[/MENTION]

Both are based on cm. Probably some issues in their ramdisk
[G2 Original Android Development] PsychoGame:
Hello [MENTION=5559940]Lawlrus[/MENTION],

Thank you for your explanation, I'm not familiar with these roms but indeed if something in ramdisk is different from CM ramdisk indeed it's giving problems booting.

Good point and didn't think of it yet, al least I'll post it in the OP that RR and Bliss do not work with this kernel to make sure that's clear to everybody who wants to try the kernel.

Greetings PsychoGame
[G2 Original Android Development] ansontyl96:
It seems that those change in your kernel will be included in the next nighty?
[G2 Original Android Development] PsychoGame:
Hello [MENTION=4640585]ansontyl96[/MENTION],

Indeed, the next nightly includes a big part of the changes included in this kernel.

I have used this kernel for over a week and so far haven't encountered any negative side effects.

Based on the fact the kernel had been downloaded multiple times for different device models (d800, d802, vs980 and l01f) but I haven't received much to nothing at all negative comments so we went ahead and merged it.

Next kernel beta release is in the pipeline at the moment and will probably be posted tomorrow.

Greetings PsychoGame
[G2 Original Android Development] ansontyl96:
Cheers mate, I can't wait to test it as the kernal I am using now already solved many lag issues for some reasons,before this kernal i always face some extreme lag from time to time probably because of cpu, but just wanna ask will there be any chance that we can fix the speaker's low volume issues?

Anyway great jobs;)
[G2 Original Android Development] syrkles:
This kernel also works on the latest vanir nightly
[G2 Original Android Development] syrkles:
Also works on crdroid!! Thank u dev
[G2 Original Android Development] PsychoGame:
Hello [MENTION=4640585]ansontyl96[/MENTION],

For now I'm just focussing on getting the kernel up-to-date with latest commits on codeaurora.org

When this is done I'll look into some know bugs which are still present in G2's CM builds.

To be honest at this point I'm not sure where the low volume bug exactly originates from (kernel or maybe device tree)

If it's a kernel problem maybe it will also be solved by getting the kernel up-to-date again, there are a lot of sound system patches to go as well.

We'll see how things work out.

For Everybody:

For now I just ask everybody to just test the kernel I'm providing and please report back with your experience.

Also do not forget to mention the ROM and device model you use with the kernel.

This way I can pinpoint more exact where eventual bugs may come from.

Greetings PsychoGame

Charging seems become extremely slow after fishing this kernel with latest nightly

Edit: Seems that the problem of charging comes from my charger, apologies for any confusion caused
[G2 Original Android Development] Mohangrmc:
Charging is ok.m using latest kernel with 11/01 nightly.the issues i found with the updated kernel

1) lower than expected headphone volume.

2)testing.........

No reboots, stable for me. D800, 1/15 nightly, and 1/16 kernel.
[G2 Original Android Development] PsychoGame:
[MENTION=4640585]ansontyl96[/MENTION],

Thank you for researching the root of the cause.

I found it somewhat strange already since I didn't touch anyrhing charging related.

Of course thuis doesn't mean it couldn't be broken by something else.

But I'm glad you found out the problem was the charger, then I don't have to dive into this problem.

Also thank you fort reporting back!

[MENTION=6029055]Mohangrmc[/MENTION],

I see your volume has become reasonable again for you.

What have you done to het the volume to reasonable volume again?

Did you have to edit some files to fix it?

If it's a kernel issue this information could help me out in debugging as well:).

Thank you for testing and reporting back!

[MENTION=1036370]ukguy115[/MENTION],

Thank you for helping out testing this kernel.

I'm glad you have a good experience with it so far :).
[G2 Original Android Development] Mohangrmc:
Thnx [MENTION=4647521]PsychoGame[/MENTION] .i have been following the development of cm13 since day one .i have been noticing a strange sound bug in almost all nightlies .that relates to inability of seeking frwrd nd backwrd in any music app .but after a few days this bug gets attenuated or eliminated on its own without any tweaking intervention .
[G2 Original Android Development] Rangell11:
[MENTION=4647521]PsychoGame[/MENTION],

Stable for me (D805, 1/14 nightly, 1/16 kernel, clean install).

I charge the battery from 0 to 100 (1h45min).

I have only two annoying bug (I think it is not related to your kernel)

1) Can not seek forward/backwards in most player (CM and Google music player app)

2)Scan any product QR Code (Portal app)

Thanks.....keep up the good work.
[G2 Original Android Development] jl10101:
It is strange that you have not encountered the issues yet - it really is an issue that I struggle with.

Thanks for your persistence though! This right now is the only bug (and it is an AOSP bug in general) that keeps CM from being my daily driver.

There has been more info in the Google bug tracker for this issue (specifically this post: https://code.google.com/p/android/issues/detail?id=170078#c60 )

Holding thumbs this gets sorted :) Thanks for the awesome work with this kernel though - have tried it and it is fixing issues here and there like the rotation graphical glitches :good:
[G2 Original Android Development] PsychoGame:
Hello [MENTION=5076742]Rangell11[/MENTION],

Thank you for your participation in testing as well.

The music thing seems to be frequently referenced.

I think it's a CM bug atm. but i'll research it as well and if it's a kernel bug i'll try to tackle it for sure.

I tested the QR codereader from Portal as well and it seems you are right this app doesn't work. Did it work in previous releases without this kernel?

I tried also barcode scanner from another app developer, this app seemed to work so to figure out if it's a regression in kernel or not it's important for me to know if this app previously worked.

Again thank you for your report.

Greetings PsychoGame
[G2 Original Android Development] Rangell11:
I think not.

I did a quick search seems like it's an old bug of CM13.

https://jira.cyanogenmod.org/browse/NIGHTLIES-2113

PS: I found this

https://github.com/zxing/zxing/issues/526
[G2 Original Android Development] ansontyl96:
I found that the scanning issues seems to be a problem from rendering as even though

Scanner related apps and whatsapp camera are showing some strange line display, if you take a photo or scan a qr code, it will still works. [MENTION=4647521]PsychoGame[/MENTION] I just wanna ask are those issues on display rendering cause by kernal or the rom itself?
[G2 Original Android Development] PsychoGame:
Hello [MENTION=4640585]ansontyl96[/MENTION],

To be honest I really don't know at this point where the rendering problems come from I need to investigate that more.

If you try Barcode scanner from Zxing team this barcode scanner seems to work as it should (at least in my case, can you test it as well?)

Rendering problems could be due to problems with binary blobs for graphics hardware, but can also be kernel related or a combination of the two.

I'll investigate it further when I have time after updating kernel.

Maybe newer graphics blobs (if there are any) will solve this problem.

Greetings PsychoGame
[G2 Original Android Development] ansontyl96:
I can confirm that scanner from zxing team works on my D802 as well on the latest nightly, also after some research it seems that the rendering issues happens on other devices running cm13 as well, so its probably a cm13 issues I guess.

Also your latest kernel works perfectly fine on my device ;)

slimport still doesn't working. (It doesn't work with stock CM kernel.)

When I plug the adapter my phone just reboot and only start after removing it.

I think it started after the slimport commits on stock kernel. (cm repo)

Kernel isn't booting on broken os.
[G2 Original Android Development] PsychoGame:
[MENTION=5263483]daniel.stuart14[/MENTION],

In updating the msm8974 kernel to latest CAF tags there are no dedicated slimport patches coming up.

When the kernel is fully up-to-date with latest CAF tags I'll ask you again if slimport is working.

If not I'm going to need your help testing/debugging for me if I want to fix it.

I don't use slimport myself so I cannot test it myself.

At least thank you for pointing it out and guiding me in the direction of where it might have got broken.

[MENTION=5559940]Lawlrus[/MENTION],

I add Broken Rom to the list of unsupported ROMs then :).

Thank you for testing and letting me know

Hello everybody,

A small update from me again.

Maybe some people noticed it or some didn't but a lot of patches from last tests have been merged now with stock CM kernel.

Up to today I haven't really been very busy with the kernel due to a busy schedule last week.

Currently I'm building a 30/01 kernel with the next set of patches to test.

Also I'm busy with figuring out why setting "Preferred Network" in current android builds doesn't work.

I'm aware of the patch which is on Gerrit atm. which seems to work around this bug, but I'll try to find a more permanent solution instead of using an overlay to the current function.

Greetings PsychoGame

Hello to all of you testers.

If you have time today could you please tell me your experience with the last beta kernel?

Positive/negative it doesn't matter all feedback is welcome and will help me understand if the patches which are pipelined are ready to be sent upstream.

[G2 Original Android Development] PsychoGame:
Hello [MENTION=3729444]chewdaniel[/MENTION],

Indeed newest builds do already include these patches from this beta and indeed some extra kernel fixes which were merged by some other developers.

To everybody who took the time to write me a review of what your experience with this kernel was thank you very much!

This way you all help me/us (the developers) make the G2 faster/more stable etc.

Today I'm preparing new kernel betas with next batch of patches.

I'm thinking about distributing a audio_policy.conf to go with this kernel which I also would like to have tested.

I don't know how you guys feel about that, please leave a reaction.

Hey is there a specific kernel control app that's used for this? I used Synapse when I had a Oneplus One and it unlocked way more settings. Is there something like that for this kernel? Or is trickstermod the best we get?

Hey [MENTION=4647521]PsychoGame[/MENTION] just flashed your kernel and noticed no tcp congestion control choice or header at all. Is that by accident or did you take it out?
[G2 Original Android Development] PsychoGame:
Hello [MENTION=3556013]johnb380[/MENTION],

Is this TCP congestion control available on stock CM kernel?

If so then there should be a regression in this kernel nut I can't really figure out which patch could have caused that.

Remark: This kernel is not about adding functions but rather test patches from CodeAurora before sending then upstream in CM Nightlies.
[G2 Original Android Development] KpKi:
Just a quike : can a universal patch for the Prefered Network type bug be made or it must be merged before building the rom ?

I am using the latest update for one full day and the battery and stability is great, but after updated the the latest cm nightly it seems that bluetooth audio is not working, not sure is it a kernal or rom issues as it is the first time i use bluetooth speaker for this few days
[G2 Original Android Development] PsychoGame:
Hello [MENTION=4640585]ansontyl96[/MENTION],

Can you provide me with some more info?

- How exactly do you connect to the bluetooth speaker and what do you notice is different from normal, or doesn't the phone connect alltogether?

- What bluetooth speaker do you use?

- Have you tried "Wiping cache & dalvik cache)"?

- If this doesn't work try stock CM kernel without my patches, do you have a back-up or do you want me to provide you one?

- Can you take logcat logs right after you tried to connect to your bluetooth speaker? (I recommend Syslog for taking the logs). You can upload the logs on pastebin or send the .zip package to me directly (contact me in PM for address).

Can you try to find out which nightly exactly introduced this problem?

Greetings PsychoGame
[G2 Original Android Development] ansontyl96:
Thank you for your reply, I can connect to a bluetooth speaker normally but when I try to play any media it plays from my phone's build in speakers instead of My Bluetooth speakers.

The speaker I am using is Archeer A209, Ive try connect it through my ipad and it works perfectly fine so I pretty sure the problem is not rise from my speakers.

I update my device to 0302 nigtly by wipe cache and dalvik cache buy this problem still exsist.

The following link is the log I toke, I hope it will helps :) Also would you mind share an backup version of cm stock kernel so I can test it?Cheers mate

Hello Draygon,

I took a quick peek at the sources of that ROM and it seems they're using CM based device tree. This doesn't neccasarily mean it works well with it.

If you'd like to know for sure just make a good back-up of at least your boot partition so you can roll back to original boot partition of Orion Rom, and just flash the beta kernel.

Worst that can happen is that it doesn't boot and you just have to restore your boot backup.

Hi PsychoGame i've tested for some days the cm13 of 04/02/16 with your kernel of 02/02/16. The system is fast but i've noticed some slowdown when i use the phone without reboot for 15+ hours caused by the ram almost full(only 170 mb of free ram without running apps verified by terminal emulator). I've fixed(more or less) tuning the lmk with +30 mb on all value. Now i'm going to test and report your newer release with the latest cm13
