MDSS version updated!! Cleaned up all spam messages and issues. Test build ready:

http://www.mediafire.com/download/zf42ni8bj1o2zij/Chaos-Kernel_v14.0-%5B08-09%5D-%5B23-54%5D.zip

Chaos-Kernel_v14.0-[08-09]-[23-54]

* MSM Hotplug and Intelli Hotplug updated to prevent interference with CPU Boost work.

* Interactive Governor updated with myfluxi's patch and tunings. (Removed crpalmer fixes/tunings) [Let's test!]

* MDSS cleanups.
[Nexus 5 Original Android Development] Audioboxer:
[MENTION=3795148]neobuddy89[/MENTION] can you explain what MDSS does? lol

Excited to try out the new bluetooth drivers. Hope issues are really fixed :D
[Nexus 5 Original Android Development] neobuddy89:
It's what you see! Mobile Display SubSystem Driver.

This driver is responsible for UI generated via panel through Linux frame buffer ioctl.

Everything's been noticeably laggier than other kernels for me on recent nightlies. Changed the minimum amount of online cores to 2 and even then scrolling/swiping displays noticeable stuttering.
[Nexus 5 Original Android Development] dhalham:
What's the advantage of using this version?
[Nexus 5 Original Android Development] neobuddy89:
Which Chaos nightly onwards?
[Nexus 5 Original Android Development] sjknight413:
I know I'm being useless here but I can't remember any specific nightly. I've been switching between your kernel, elementalx and another for the last three weeks or so and yours has seemed to get laggier everytime I try it whereas when I return to the others they are smooth as anything.

I'm not doing anything special with my system, I full wipe occasionally when switching kernels for peace of mind and I just run stock cyanogenmod with no mods or anything.

It's laggier in high performance gaming too. I use ppsspp to emulate a few PSP games, they all run amazingly on the other two kernels but on yours it stutters a lot, it also stutters the same amount with the stock cm kernel if that's any help?
[Nexus 5 Original Android Development] Audioboxer:
Thanks.

Franco Display app seems to have issues on the latest nightly. Not sure if there's issues with gamma control in general or something has changed which has broke that app only.
[Nexus 5 Original Android Development] Dudebowski:
The one you built today at 2, noticeably smoother graphics. Did you force the governor to thE test Intellidemand? Coulda sworn I had it set to intelliactive.
[Nexus 5 Original Android Development] topgeardave:
Think I prefer previous nightly, just because it was easier on the battery due to staying on 1ghz most of the time
[Nexus 5 Original Android Development] kong:
+1 on smoother graphics.
[Nexus 5 Original Android Development] neobuddy89:
The nightly build at 2 has different interactive governor and cpuboost settings. In last test version, interactive and cpuboost governor settings are changed to match with CM11.

[MENTION=2185591]sjknight413[/MENTION] Can you please try last NIGHTLY build?? not test build.

Is the display app recently updated?
[Nexus 5 Original Android Development] Audioboxer:
Hasn't been updated since January. Maybe just not playing well with MDSS updates.
[Nexus 5 Original Android Development] topgeardave:
Second day of using the kernel, battery life is same as the nightly before. Guess the first day of flashing a kernel doesn't really help with a true picture of battery usage. I would definitely say this is the way forward :)
[Nexus 5 Original Android Development] giajp:
Yep, just amazing!

Mdss...interactive... All fixed, all perfect

Best battery Life on n5

Above 35000

[Nexus 5 Original Android Development] sjknight413:

Download trickstermod, change the governor settings to target more higher freqs
[Nexus 5 Original Android Development] giajp:
I don't play any games, for my usage, totally useless 4cores and GPU over 200mhz. Best battery saving is possibile to decrease the clock, the number of cores and to manage the interactive.

I just made my first switch to ART... maybe placebo but everything seems quite buttery. The startup apps I've got seemed to finish their cpu time much faster, the graphics seem quite smooth, more so than with dalvik anyhow. This all seen with the build from this afternoon. Neo, is there intentional optimization for art, or is it just that awesome? also wondering if dalvik dev has just halted entirely since goo had to legally/financially come up with their own runtime to cut their ties with Oracle... pretty impressed so far I guess we'll see if there's any old incompatible stuff as I go along
[Nexus 5 Original Android Development] mo976:
You may have incompatibilities with older apps that haven't been updated in a long time, most major apps have long been updated to support art and Android 4.4+.

Neobuddy

I'm not sure if something changed but inteliactive caused a lot of scroll lag and general slowdown on the latest test build, interactive is working great (im using battery profile). Battery seems to have taken a bit of hit though overall.
[Nexus 5 Original Android Development] bosna110:
What in the world are you doing to your device to get over 35,300 and get unbelievable battery life. Mind sharing full kernel layout, with any links if you flashed anything over the kernel? I'd like to try it too.
[Nexus 5 Original Android Development] topgeardave:
Use normal settings mate, or in the battery one change online cores to 4 and touch boosted cpus to 2. I can get between 5-6h SOT under mixed wifi and H+
[Nexus 5 Original Android Development] neobuddy89:
I am working to merge parts from last nightly to new test for interactive governor. Let's see.

Will upload build soon.
[Nexus 5 Original Android Development] nils.pap:
Unfortunately I am having issues with Bluetooth connectivity as well. The battery life is really awesome but the Bluetooth connection is really buggy.

Is there anything we can do to help you sort this out? I'm willing to provide logs or help debug if needed :)
[Nexus 5 Original Android Development] neobuddy89:
Yes. Capture logs using buttons in bug-report and send back.

Also, are you having same connectivity issues with stock CM11 kernel?
[Nexus 5 Original Android Development] nils.pap:
Unfortunately, yes. Same issues with stock CM kernel. Tried out elementalX kernel and had no issues though.

I'll send the logs as soon as possible. Thanks for looking into this!
[Nexus 5 Original Android Development] ryukiri:
Do you guys happen to have a stock cm kernel somewhere you can upload? Prefer flashable zip since I'm on vacation and would like to switch over to elemental x. (Can't download full ROM before flashing ex because download speed here is about 17kb/s)
[Nexus 5 Original Android Development] topgeardave:
Do you not keep the cm rom on your phone? As a rule of thumb you should always keep the rom and a nandroid on your phone. Seeing as chaos kernel changes a few files as well as the boot.img you're buggered pretty much. I'd say do a nandroid then flash ElementalX. In theory it should work fine
[Nexus 5 Original Android Development] ryukiri:
No I dont :( ..wanted to save space for pictures...usually I compile my own and adb sideload it and then sideload the kernel (in this case chaos)..alright I'll try flashing it on top..thanks though :)
[Nexus 5 Original Android Development] Dudebowski:
if you want to take your chances, here's a kernel from a recent nightly, just the boot.img and updater script. pretty sure i put it together correctly....?

EDIT: meh, the manifest is broken, i don't have a signing tool. i suppose msot of us aren't doing sig checks anyway but yeah, anyay happy travels :highfive:
[Nexus 5 Original Android Development] ryukiri:
Thanks! :)...I already flashed ex on top of chaos before I saw this and so far it works fine..will be out all day tomorrow sightseeing so I guess I'll find out if anything is wrong then :P
[Nexus 5 Original Android Development] neobuddy89:
Interactive governor Test version:

* Merge all optimizations of interactive governor in one.

* Tune config.

* Update audio policy.

Download here:

http://www.mediafire.com/download/n7nikjg786841nn/Chaos-Kernel_v14.0-%5B08-12%5D-%5B00-48%5D.zip

Only tunable I am not sure is io_is_busy, any inputs will be helpful.

Please test and review back. (And yes, mdss updates included!)

P.S. Testing with max_online_cpus_susp = 1. No audio glitches. :)
[Nexus 5 Original Android Development] neobuddy89:
Which CM nightly are you using?
[Nexus 5 Original Android Development] nils.pap:
20148010 at the moment, I usually update once per week or so.
[Nexus 5 Original Android Development] topgeardave:
Latest nightly is running like a boss! Great work mate :)
[Nexus 5 Original Android Development] _MirageX_:
Io_is_busy just means that cpu will be bumped to a higher frequency while data is transfering between blocks, which in my opinion is pointless, i keep it on 0, even though Google or some experienced devs like franco choose to set it on 1

Oh, and, as a side note: every time i flash your audio policy it has the wrong permissions (rwxrw-r--), I don't know if it's fixed in this release (should be rw-r--r--), so I'll just point it out :)
[Nexus 5 Original Android Development] fluther:
Latest test is good, but I'm still getting a crash when using USB audio if I go anywhere near DSP manager, even looking at the QS dynamic tile. Logs:

[MENTION=3795148]neobuddy89[/MENTION]: Problems with BT still persist. Twice is connect correctly and at the third attempt BT freezes. It would be possible (at least try) use parts about BT of the source code of ElementalX and import them into your kernel? When I tested this weekend ElementalX kernel, so I had absolutely no problem with BT. Even I found that BT work better and faster.
[Nexus 5 Original Android Development] topgeardave:
Hey [MENTION=3795148]neobuddy89[/MENTION], amazing battery life on latest kernel! Just thought I had to share
[Nexus 5 Original Android Development] neobuddy89:
This test version with io_is_busy = 0 will be next nightly version.

Since no mdss issues being reported, and none faced by me as well...

I consider mdss updates are stable enough and will be part of nightlies!
[Nexus 5 Original Android Development] neobuddy89:
Logs please.
[Nexus 5 Original Android Development] RKSoftware:
[MENTION=3795148]neobuddy89[/MENTION]: Hello I attach the logs from my phone. Thank you in advance for your help!

EDIT: Yesterday I had problems with BT to connect to my Parrot CK3100 HF. Twice the phone with HF connected normally, but the third is already not connect. I had to turn off and then turn on BT and the phone reconnected. When I left the car, so I found out that BT remained in the frozen state, when the thought that it is still connected to HF. Again, I had to turn off and turn on BT. I have noticed one thing with Chaos kernel the phone is connected to the HF to about 1 minute, but with the ElementalX it is within a few seconds even for the synchronization of contacts with HF is at ElementalX faster.

Hello. Sometimes when someone call me my screen won't wake up (last cm nightly and last kernel). Here a last-kmsg. I will see if this happening with stock settings.

Thanks
[Nexus 5 Original Android Development] Super-Android:
Hey, really proud to see you developing and building. Holaaa...

Love your kernel man..

But had a persistent issue with dis kernel.

Sometimes when I am in a call and the proximity sensor comes in to picture and the screen turns off.. but the when i move the phone back in the palm again, the screen does not turns back on. I have had this problem, the only solution is, I reboot it to the bootloader and the restart the phone.

I am not sure, how can i capture the log, I am a noob, please pardon me.

Just wanted to use this kernel.

I am currently using ElementalX kernel.

No such problem,
[Nexus 5 Original Android Development] vtec_:
This is a problem with stock CM as well, need to get a log on a Milestone but haven't got round to it.

Switching between QS and main notification area while listening to USB audio always caused a SOD.
[Nexus 5 Original Android Development] fluther:
Oh really? Hadn't realised that. What's the best way of getting cm to look at this?
[Nexus 5 Original Android Development] vtec_:
Putting a log up on jira (error reporting website). Has to be on a stock milestone as well, e.g M9 snapshot.

BT issues

Hello! Looks like there are some problems with Bluetooth for me either. It looks like after some use, G watch would have only one-way connection(Android Wear device would receive notifications from phone, but any request to the phone-searching something or setting an alarm clock would fail). I've attached dmesg, if you need something else, I'd be glad to supply it. Thanks.
[Nexus 5 Original Android Development] fluther:
Does anyone else have trouble with their compass? It's rubbish, mine is almost always 90° east of where it should be. Is this a kernel issue? (I suspect not but I'd be interested to hear if anyone else is having difficulties)
[Nexus 5 Original Android Development] topgeardave:
Nope, kernel/userspace only read what information is sent by the sensor. There was a way to clear them but I've forgotten it. I remember when people flashed the M8 port at the beginning, their sensors broke but wiping some files fixed it
[Nexus 5 Original Android Development] lolobarjo:
It's reappeared with stock settings but I can't provide you lolcat this time. Sorry
[Nexus 5 Original Android Development] topgeardave:
[MENTION=3795148]neobuddy89[/MENTION] I think you can call latest nightly stable! Been giving this phone some heavy work and it's fine :)
[Nexus 5 Original Android Development] omvir:
Hi guys, I'm wondering if I'm the only one with SOD issues when trying to wake the phone(easily reproducible by spam clicking the power button, but it happens normally as well when trying to wake the phone sometimes)? I can't use this kernel for more than 2 days without facing this SOD. I've given logs a while back, but I guess they didn't show anything. This doesn't happen on other CM kernels.

It happens with and without those display panel update commits. My setup: Stock kernel settings on cm nightlies.
[Nexus 5 Original Android Development] fluther:
Two SoDs for me today :( no logs, I'm flathunting so no time.
[Nexus 5 Original Android Development] neobuddy89:
ULPS disabled by CM11 kernel. We will also disable same and see if that helps.
[Nexus 5 Original Android Development] nokiagye:
Hi on ls won't working
[Nexus 5 Original Android Development] omvir:
Is your issue reproducible when you spam click the power on button? And how does your usually occur? What kind of scenario? If its while turning the screen on then we have the same issue.
[Nexus 5 Original Android Development] lolobarjo:
I have also this issue
[Nexus 5 Original Android Development] fluther:
Haven't tried spamming the power button, but I don't really want to, it doesn't sound like a great idea.

Mine occurs while trying to wake from sleep. Sometimes it just happens, and other times it happens after a notification has come in. My LED will keep signalling, and sometimes the backlight does come on, but displays nothing but black.

---------- Post added at 11:23 PM ---------- Previous post was at 11:21 PM ----------

Here's hoping. Why did CM decide to nix ULPS? Same reason? I haven't used the stock CM kernel in ages so I don't know if it happens.
[Nexus 5 Original Android Development] defconoi:

[Nexus 5 Original Android Development] topgeardave:

[Nexus 5 Original Android Development] topgeardave:
Just a punt, could you change suspend defer time to 5 seconds? I have it on 5 for stability reasons. And turn master limiter on and then see if you get any more mdss issues
[Nexus 5 Original Android Development] fluther:
I have suspend defer down to 0, and it SoDs on both 0 and 10. Same deal with limiter, SoD whether enabled or disabled.

Why does my device (and yours Dave) seem so much more temperamental than neobuddy and everyone else's?
[Nexus 5 Original Android Development] topgeardave:
I haven't received a SOD on my phone with this nightly, I think it's because many are using the stable version and not the nightly. If you look at downloads of nightlies it's not an awful lot so we're the guinea pigs in a way haha
[Nexus 5 Original Android Development] sickleman:
Logcat output?

Is there any way to enable logcat in this kernel?

Like a month or so, I was told, that the logcat is temporary disabled in (then) recent builds.

Now (after testing L android) I'm back to KitKat, CyanogenMod and this kernel, and after these whole time, this (pretty much important) bug isn't fixed yet?

(go to NXTTweaks, then go to Tweaks, and then just enable it :) sorryyy for complaining :) )
[Nexus 5 Original Android Development] topgeardave:
If you press logcat in nxtweaks, it captures a logcat for 60 seconds and saves it to sd card.

[Nexus 5 Original Android Development] topgeardave:
Could you explain specifically which problems you actually have?
[Nexus 5 Original Android Development] omvir:
1 problem. Turning my phone to a screen on state from a screen off state causes a SOD. I can see my notification light and everything but nothing on the screen. It happens maybe every 50 screen off to on cycles. But I can reproduce it very fast by simply clicking the power button about 5-6 times not too fast not too slow.
[Nexus 5 Original Android Development] topgeardave:
Keep scrolling back till you find the nightly where the mdss parts were squashed. I think mdss issues are hit and miss as I've not experienced any yet
[Nexus 5 Original Android Development] omvir:
Its happened on both versions for me. I've tried already. But I will try again anyways.

With the mdss commits in the cm kernel a few night lies ago, it was not reproducible. Maybe they don't have to do with this certain issue? Idk lol I give upppppp. I'll try that mdss squashed kernel again tho.

Hi

I manage to forget to flash stock kernel before i flashed Chaos, came from ElementalX, and now i have no GSM signal.

Reflashed stock kernel back, and reflashed Chaos etc but without any luck.

I`m sure this one is a Classic lol :(

Hope someone can help me recover from it :)
[Nexus 5 Original Android Development] californicated:
[MENTION=1138704]Digidice[/MENTION]

Reflash ROM. Do you have a backup of your phones efs data? Might be needed to restore
[Nexus 5 Original Android Development] Digidice:
I flashed the CM ROM file over the current one again, still no luck.

I have an nandroid backup from my stock 4.4 rooted only.

Dont think resoring the efs from that one will fix it ?
[Nexus 5 Original Android Development] californicated:
EFS should always be the same for your phone unless it gets corrupted. So I suggest you to try it
[Nexus 5 Original Android Development] _MirageX_:
does it show baseband unknown? You should never flash two kernel that modify the ramdisk in a row. Just reflash stock cm kernel via fastboot than chaos.
[Nexus 5 Original Android Development] Digidice:
Thank you both, i managed to restore the efs and reflash and it was good again.

The phone had me there and i was sure it was bricking time.

Now i learn to always read every line of instalations hehe
[Nexus 5 Original Android Development] _MirageX_:
sorry to bother but... did you just say you got efs corrupted just switching kernel? It seems reaaaally strange to me. Anyway, glad you got it sorted :)
[Nexus 5 Original Android Development] topgeardave:
There was nothing wrong, he just wasn't patient. I've noticed in the last few nightlies when flashing fresh it takes about a minute for the phone to get a signal upon first boot.

* Merge all dev done in test builds (including interactive governor updates)

* Disable ULPS

* Cumulative linux 3.4.103 update

* Little tuning for interactive to save slightly more power

* Built with updated hammerhead optimized toolchain

* Disable some unwanted debug parts and update build config.

BT issues are not addressed. I need to go through logs shared earlier.
