Camera acts very strange. Using Google Camera the preview is laggy and is constantly flashing and harshly auto focusing. The screen will flash green sometimes. This only happens in Camera Mode, Photo Sphere, and Panorama. Lens Blur and Video modes appear to work fine. The Front Facing camera works fine.
[Nexus 5 Android Development] big_bum:
I've seen some lag in camera app too, but no flashing and focus problems. I've reverted the camera changes, and pushed a new build. Let's see if it's all good.

I tried to install this kernel on a rom secondary (in MultiROM) but I had booloop !!

There needs to be some particular patch?

Sorry for OT
[Nexus 5 Android Development] shadowdevil:
Yea Sure [MENTION=4857170]big_bum[/MENTION]..:)

Flashed the latest build from test folder..installation went smooth.!

EDIT :Frequently touch seems to be locked up..cant do anything..after few sec will get back to normal !

Battery also draining too fast compared to other versions!!

Reverted to v6 !!

Cheers..!!
[Nexus 5 Android Development] Alcolawl:
Still have the same problem with Google Camera. I tried the built in Camera app and it seems to perform much better (though, it still slows down a little in certain lighting situations). Kinda sucks that it's missing features like HDR+ and stuff but it'll do for now. I'm assuming it's more of a problem with Google Camera than your Kernel.
[Nexus 5 Android Development] shadowdevil:
Sorry i didn't see that much lag in Google Camera app and no green flashing..!!
[Nexus 5 Android Development] big_bum:
We need more people to test the "buggy" build. I saw lag in the camera app, but it's normal lag, not freezing. I've never seen the green flashing either, but [MENTION=4752299]Alcolawl[/MENTION] saw it.

Right now I've reverted the camera commits, so the V7 in the test-folder doesn't have the camera changes from KK. I'll publish a new build with the camera changes included, but right now I have to go to the hospital.
[Nexus 5 Android Development] shadowdevil:
Okies !!!
[Nexus 5 Android Development] big_bum:
Done. Uploaded a build called L-camera-v7. Test it and check if you see any issues with the camera.

Does Lollipop work with MultiROM? I see you need a special installer script, from what I could search in 2 minutes on XDA: http://xdaforums.com/google-nexus-5/orig-development/mod-multirom-v24-t2571011/page250
[Nexus 5 Android Development] big_bum:
I think I found the faulty commit that broke the camera.

I uploaded a build called L-camerafixed. Please test and let me know if there are any problems with the camera.
[Nexus 5 Android Development] fabi_92:
yes .. multirom work on lollipop. i use big bum as primary but with some secondary rom and some kernel doesn't work.

code blue for example allows to install the kernel with secondary and the procedure is this:

flash rom

flash gapps

flash code blue

flash zip EXT4 or F2FS

done

the same uber l.

there is a chance to do something like this? would be great

excuse thank for everything; i love this kernel ;)

EDIT: for the rom this is a possible solution: http://xdaforums.com/showpost.php?p=58030246&postcount=2393

EDIT2: [MENTION=4857170]big_bum[/MENTION] I tried to flash the file EXT4: WORK! great! it's compatible.

is to be changed without messing with code blue but it works :)

I repeat...

multirom secondary:

- Flash rom

- Flash gapps

- Flash Big Bum kernel

- Flash EXT4 or F2FS zip

- Done

;)
[Nexus 5 Android Development] Alcolawl:
Whatever you changed absolutely worked because my camera is butter smooth now. Tested using both the AOSP Camera and Google Camera. Nice!
[Nexus 5 Android Development] big_bum:
Cool, I'll put that in OP.

I'm having Bluetooth issues. It'll be working fine for a while, then Bluetooth will sporadically connect and disconnect, then finally Bluetooth will just shut off and won't allow me to toggle it back on.

This is connected to my g watch. This problem only started to occur after clean flashing this kernel.
[Nexus 5 Android Development] buru898:
Don't know if this will help
[Nexus 5 Android Development] big_bum:
Can you try the latest V7 test build?

I've reverted all the bluetooth changes.
[Nexus 5 Android Development] buru898:
If you mean the one named camerafixed v7, that's the one I'm on.

I can't say if it happened on v6 as I was using a different kernel.
[Nexus 5 Android Development] big_bum:
Not that one. I didn't revert the bluetooth before you told me you have problems, and that build was compiled before that. Check the test folders for a build from today.
[Nexus 5 Android Development] buru898:
Ignore previous post, downloading and will be testing now.
[Nexus 5 Android Development] big_bum:
I don't always update Dropbox, that's why I put the main server first. I've uploaded the files to Dropbox, now you can find them there too.
[Nexus 5 Android Development] buru898:
Been using it for a while, it works and doesn't randomly disconnect on and off, but my Bluetooth just turns off and stays off until I go back into the settings and enable it again, then it connects to my watch fine.
[Nexus 5 Android Development] big_bum:
The test build has the stock android kernel bluetooth stack. I'll build the kernel with bluetooth on -O2, maybe bluetooth doesn't like my optimizations, but if that doesn't help, you're out of luck.

Edit: See the new build.

[Nexus 5 Android Development] buru898:
Already got a random connect and disconnect while I was on my phone. The Bluetooth icon didn't go away, but my watch is set to vibrate 3 times when it disconnects, so I check my watch and it was, then shortly after it reconnected.

Hope this screenshot helps?
[Nexus 5 Android Development] big_bum:
The screenshot just confirms what you said. I don't have a clue why the bluetooth does that. I've reverted a change in the ramdisk which affected bluetooth and pushed a new build, but besides that, I don't know what to do.

[Nexus 5 Android Development] :
Is there any way you could include more governors? I'm really missing smartmax_eps. My battery lasts for ages with it.
[Nexus 5 Android Development] big_bum:
1. See the name of the wakelock and try to disable it via Disable Service app.

2. From AppOps disable the location for Android System.

3. Go to Settings>Storage, click on Cache, confirm deletion.

I can include it if you give a link or a source for it.

[Nexus 5 Android Development] Ben36:
Just trying out this kernel, may I ask. The dimmer is rated in numbers. What number is relevant to the stock dim level?
[Nexus 5 Android Development] big_bum:
The stock minimum brightness is set to 5.
[Nexus 5 Android Development] Ben36:
So with the dimmer module turned off, it's the same as 5?
[Nexus 5 Android Development] big_bum:
Without the dimmer, the minimum level will be set by dev->min_brightness; which is 5 from what I see in the code, so yes.

Keep in mind that we scale exponential, not linear as stock, so the brightness curve looks a little different. (Less brightness in the same lower light conditions compared to stock)
[Nexus 5 Android Development] Ben36:
Thanks. Was just trying to work it out in my head.

MPD is soo much smoother than all these hotplugging kernels about imo!
[Nexus 5 Android Development] marf28101995:
How about give proper credits to blue kernel dev ? 90% the merges you made are made by him before so I think you should add someone to credits list

Cheers
[Nexus 5 Android Development] big_bum:
How about reading the first post where I clearly say from where I get the code? It's clearly written that I cherry-pick from Chaos(now Hybrid), Uber and Code_Blue, but if mentioning the dev makes you sleep better at night, so be it.

I announce test builds when I want more people to test it and when I feel it's safe/close to a release. If it's not announced here (the official thread), then it might kill your kitten or steal your car. :P

[Nexus 5 Android Development] big_bum:
Or better: don't stalk me! :laugh:

Now seriously: It's in the folder but it's not announced here, then:

1. it isn't worth flashing over the previous beta (nothing big changed)

2. it contains something that might dissapear in the next version for various reasons and I want only a few people to test

3. I don't have to announce every test version if #1 and/or #2

EDIT:

New test builds: Linaro and SaberMod.
[Nexus 5 Android Development] shadowdevil:
Right now on big_bum v7SM..seems to be good..no hiccups till now..! :)

As usual nice work [MENTION=4857170]big_bum[/MENTION]

[Nexus 5 Android Development] timo_capa:
Well, which version is better?

Linaro or SaberMod?
[Nexus 5 Android Development] PowkyE:
Why if I flash your kernel who are in folder 6, when I boot my nexus, I can't use it? The display don't show me nothing and I am using blisspop ROM cm12 based :c
[Nexus 5 Android Development] big_bum:
Like a fine tuned V7 engine, right? :))

Have you checked the md5sum? You downloaded the zip file? I see a incomplete zip download. Does it go past Google logo? Has blisspop switched to caf?
[Nexus 5 Android Development] big_bum:
Linaro or SaberMod.

It's said that Sabermod gives you a little more performance at the cost of battery life.

Linaro is more battery friendly and it might seem smoother.

I'm using SaberMod right now, with V7.
[Nexus 5 Android Development] big_bum:
V7

From now on, I'll provide Linaro and SaberMod versions for this kernel.

USB stack is now at 3.4.105

FUSE/vfs/fat/fs fixes from 3.5, 3.6 and 3.7

qseecom updates from CM

f2fs updates from upstream

memory optimizations from motorola for our board are now merged with cortex ones

NET is 3.4.105

some video driver updates

selinux fixes

leds fixes

msm camera updates working as it should now

bluetooth is build at -O2 and I have reverted all the changes to stock kernel

enabled all frequencies for the CPU. Battery tests showed no (much) gain, but no loss either. [MENTION=4634686]fabi_92[/MENTION] reported that the phone feels smoother, so it stays this way.

interactive: updates from CM/myfluxi

interactive: added a tunable in which you can choose the way the frequency is calculated (the old way, or the new load-based way). Writing 1 in /sys/devices/system/cpu/cpufreq/interactive/use_cpu_load will enable the new way of calculating the freq.

interactive: added a tunable to set the load threshold if you think the CPU doesn't stay enough in the minimum freq, but I recommend leaving it to 0 or not with it past 10-15.

added smartmax gov by request. It's not tuned and I don't offer support for it, so if you have crashes with it don't post them here.

underclocked GPU idle. The GPU runs at 20MHz now, instead of 27Mhz.

reduced wifi wakelocks

raised the thermal threshold frequency. It now goes down to 1.7GHz instead of 1.5Ghz, then if the cpu is still hot, it will the freq to 1.5GHz instead of 1.2GHz

Makefiles changes: merged some flags from Uber, added some parameters for our CPU, enabled hardfloat for NEON and VFP

mutex, rtmutex, semaphores updates

added tripndroid IO sched

I probably forgot something.
[Nexus 5 Android Development] pandza88:

You can always try the new tunable in interactive if you want. It's there so you can use/test it.
[Nexus 5 Android Development] shadowdevil:
Yup absolutely..!!

Right now on final refined v7 Linaro engine..jus awesome work mate..!

NB: As you said..yes Linaro is defenitely smoother than SM..Love it..!:)

WTF KERNEL!!! amazing work man!!! This is my first flash v7 and I'am speechless!!! Dont know about battery but fluidity and perfomance, smoothness is stunning (linarno), there is no any other to even close to this, and I tried most popular here.. Keep it more like this!!! Cheers

New governor "impulse" coool...!!!

EDIT : Tried new test version it feels little bit stuttering in animation than the previous build..other than that all good!!
[Nexus 5 Android Development] timo_capa:
Will the ability to overclock eventually come?

(GPU & CPU?)
[Nexus 5 Android Development] big_bum:
I'm not planning adding GPU OC, but I might add CPU OC if more people request it.
[Nexus 5 Android Development] timo_capa:
I feel like every kernel that allowes GPU OC doesn't stick with it.

If I set the min & max performance to 650 MHz and change the governor to performance (Uber kernel), it's stuck at 450 MHz, which would be stock max speed.

You know why?
[Nexus 5 Android Development] big_bum:
I don't know how you set your phone or how do you tell that it isn't working, how you see the freq, how do you test, etc. Go and ask for support in the Uber kernel thread.
[Nexus 5 Android Development] michelesdc:
Thank you for your work big bum, i like very much your work but with v7 i've bam dmux wakelock, do you know why? I read that is about 3g or aomething similari. The ROM is cataclysm.

New V8 test - 0c2fdf9
[Nexus 5 Android Development] madsurgeon:
HH is flying on V8-SM. Thank you Dev for sharing your work.
[Nexus 5 Android Development] big_bum:
This is it guys.

V8 is exactly what and how I want my daily usage kernel to be. I've added all that I've wanted in this version and I feel that there isn't much to add.

So this is it. The final/last/latest version of big-bum. The last doesn't mean the developement has stopped, it means that it slowed down, since there are any new features to add at the moment.

This being said, 1175 commits after V7, we have:

- Linux 3.4.106

- workqueue backports from [MENTION=2376110]dorimanx[/MENTION], with a new tunable: power efficient workqueue (disabled by default). You can tune in Synapse or in /sys/module/workqueue/parameters/power_efficient

- cpufreq/cpuidle/sched updates and fixes from [MENTION=3795148]neobuddy89[/MENTION]

- crypto changes from CM

- ext4 updates

- dynamic fsync (just like in KK version)

- added the sound changes from CM/CAF

- wifi driver from Galaxy S5 , thanks to [MENTION=4152171]myfluxi[/MENTION]

- a new KCAL driver from [MENTION=4316709]savoca[/MENTION] (a bonus from me: a little bit of contrast and saturation added by default. Nothing intrusive, just a little boost to make our screen shine). Tune in /sys/devices/platform/kcal_ctrl.0/

- impulse governor from [MENTION=3795148]neobuddy89[/MENTION] (great guy, thanks for all help)

- built with Linaro from Uber Kernel, toolchain is built from source.

- refreshed the build flags, and made them less aggressive

- I probably forgot something

Donations are not required, but are greatly appreciated.

I also started a caf kernel, since CM posted a caf tree yesterday night. I'm currently running Blisspop and I think they will switch soon to CAF, since CM will do that too. We'll see you there.
[Nexus 5 Android Development] Tylog:
Good job bumbum xD let's the what caf give is in the future, I sure a few good things come:)
[Nexus 5 Android Development] big_bum:
^ I think ULPS is one feature worth switching to CAF.
[Nexus 5 Android Development] fKm:
I feel like i have to flash this again ;) Right now I am on neobuddy89s kernel. Anything I have to check before I flash this one?
[Nexus 5 Android Development] big_bum:
^Nope, just flash the zip or the image and you're good to go. I made this switch too (went from mine to his, then back to mine), when I merged the sound patched from him and it went ok.
[Nexus 5 Android Development] fKm:
Worked great. Thank you for the quick help and the great kernel.
[Nexus 5 Android Development] island3r:
Soooo, is it just me or are all cores always on? Load threshold value appears to have no effect.
[Nexus 5 Android Development] big_bum:
It's just you. What load threshold?
[Nexus 5 Android Development] island3r:
Yes I am pretty sure I borked something, but I had to ask just to be sure.

I am talking about the load_threshold value in governor control. You know the one that determines the hotplug aggresiveness of interactive governor. No matter what I set it to, I always get all 4 cores on. Also now that I notice it, after a reboot I always get a 1,3 ghz minimum frequency. Which is super weird.
[Nexus 5 Android Development] big_bum:
Hotplug is controlled by MPD. load_threshold controlls the minimum load at which the cpu is not upped to a higher freq.

Let me guess: Euphoria OS?
[Nexus 5 Android Development] island3r:
Ah mpd, I see. I am a long time slim+franco user, so I am a bit unfamiliar with how mpd works. However I am pretty sure that hotplug load_threshold determines the load at which the hotplugging occurs (at least on franco's driver).

So, any idea what could be happening here? (Again I am not saying this is the kernel's fault, I'm just curious).
[Nexus 5 Android Development] big_bum:
Its because mpd isnt starting. Also, my ramdisk gets overwritten by the rom. Ive seen that in Euphoria.

And yes, you're right about hotplug load threshold, but we dont have franco's hotplug anymore. We never had it in Lollipop.

[Nexus 5 Android Development] bluizzo:
Hey I had this issue with other kernels though. I reverted back to stock kernel, and had that issue as well, but I had a theme on. After I removed the theme, it worked. But I haven't tried a kernel yet to see if it was that. Anyways try going back to stock theme if you're using the one with the CM Theme Chooser
[Nexus 5 Android Development] bland.life:
Thanks for the clue.

Tired from the flashing session today already.

Settling back on the last version of the ROM.
[Nexus 5 Android Development] big_bum:
Tell me if it's fixed. Iit might be the ROM, since the kernel doesn't know about the SIM PIN. It does know about encryption though, and I made some changes to encryption.

Anyway, I think a new version is coming soon. I've been fiddling with an in-kernel hotplug replacement for my caf kernel, and I love it. I think I am the only one left with qcom mpd, and even if it's playing nice with some ROMs, with some it doesn't. (I even had problems on CM CAF with it).

Here are some screenshots with CM CAF and msm_hotplug. Wifi on all the time, not the best 4G signal. I used the phone for browsing, reddit, twitter, a little playing.
[Nexus 5 Android Development] bluizzo:
I doubt it's the kernel causing the problems, but it seems it has to do with the theme chooser. Because had the same issue again with a clean install. But don't wanna sound like I'm *****ing. Appreciate your work ?
[Nexus 5 Android Development] big_bum:
Check the main test folder for a CAF version. It's CM CAF + a little big_bum.

See test folder for a V9.

I also pushed V10: the same as V9, but with 5.1 ramdisk. If it boots, then OK, if not, there won't be a 5.1 version soon.

EDIT: use the multimount version for f2fs partitions. It should work.
[Nexus 5 Android Development] shadowdevil:
v9 test is good..! :good:

Running smoothly...so far so good..!
[Nexus 5 Android Development] big_bum:
Battery life? Worse/the same/better?

We'll have a official V9 and V10 soon (as in as soon as I manage to restore the virtual machine on which I build the kernels). V9 will be the last version for 5.0.x, V10 will be the first official for 5.1. I'll probably release the CAF version at the same time.
[Nexus 5 Android Development] shadowdevil:
EDIT: Well about battery life..so after 1 week with test v9... battery life is not that much good..!
