Am i being a total noob or is it really hard to find a download link for the F2FS kernel... I am about to test CM roms now and i started looking for a kernel.. But no luck finding the F2FS version... :/

Also btw, what GPU frequency do you guys recommend? Id love to have some extra performance but my phone overheats often as it is... (being on iHackers thus far)

Thank you in advance, and i would really appreciate any more tips on CM based stuff... Think of it as the stuff you would like some1 to have told u when u started :) :angel:

[Xperia Z1 Original Android Development] sm.vassallo:
Click on the ext4 download, on that page click his name and it will show you all his downloads and there you with find the F2FS kernel.

I am thinking of using it too, is it compatible with the latest PAC-man ROM?

I have strange random reboots... Here is my kmsg log...

https://www.dropbox.com/s/jnh511xk6n9zu1y/2014-05-05_11.55-random.zip

I'm on latest nightly (04/05) and i'm pretty sure is kernel fault.

Also, happens more frequently if you open the camera. (About that, the camera often don't work, still blank and then reboot)

What are the things that are included in the boot.img file of Pimped Kernel? I am asking because I want to replace it with the .img file from Philz Touch. But if in your .img kernel functions are included I can't do the file change. Sadly I haven't found an easy description what is included into the file in general.
[Xperia Z1 Original Android Development] ekanix20:
This kernel has all the features from first post. And the recovery is Stock CWM. Don't know what you are asking about really.
[Xperia Z1 Original Android Development] ->---:
In the .zip from PimpedKernel is a boot.img file. PhilzTouch also is an .img file. So my thoughts were, if the .img is just the recovery I can change it by switching the .img in the .zip. Just taking the easiest way. But, as you tell me, the features of PimpedKernel are part of the .img so my way want work as intended.
[Xperia Z1 Original Android Development] Poesini:
It doesnt really work that way... but if you want you can edit the script to flash the .img to the FOTAkernel partition

[Xperia Z1 Original Android Development] lowrider_05:
this kernel works good and i really like the intelliactive implementation :good:

EDIT: can you please modify your app so we can set a governor for all 4 cores without running a benchmark in the background so all 4 cores are online and selectable in the PimpmyZ1 tool?
[Xperia Z1 Original Android Development] Androguide.fr:
The problem is that when a core is offline you can't set its governor.

I will soon add polling to the app so that as soon as a core gets back online the spinner is available.

How? Before perform the hard reboot, with my pc?

I've seen that This issue occurs only with very low battery (>5%)... I'm not sure, but seems so...
[Xperia Z1 Original Android Development] Androguide.fr:
Yeah, hook the device to your pc, you should be able to have adb access to it (and you can reboot it using adb reboot instead of bothering with the hidden reset button).

If you reboot the device using the hardware reset button, the ram console will most likely be dumped and the kmsg will be lost.

Please also grab a dmesg using:

adb shell dmesg > dmesg.txt

[Xperia Z1 Original Android Development] ekanix20:
Sorry it does not work that way :( the boot.IMG is the kernel itself, including a recovery.
[Xperia Z1 Original Android Development] ->---:
I tried it as most of the time. Just the brutal way. And guess what, I could not get the XZ1 to boot. :eek: Gladly I could enter fastboot mode and used flashtool to try the kernel from Philz a second time. But no way. Maybe there was something killed by my dirty try or it just does not work. Did not had the nerves to try. So I extracted the boot.img from PimpedKernel.zip and flashed that with fastboot. After that I could boot and reflashed, just for safety, the PimpedKernel.zip. :victory:

For some creepy minutes I thought I killed something important. Gladly the devices are relatively error resistant in the meantime. ;)
[Xperia Z1 Original Android Development] ekanix20:
You learn from your mistakes ;) been there done that
[Xperia Z1 Original Android Development] Androguide.fr:
You can very easily install Philz or TWRP over the included CWM.

Simply download the recovery image from their respective threads, place in in /sdcard. For this example let's say we renamed it to recovery.img.

Then just fire-up terminal emulator (or an adb shell) and enter the following command:

dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/FOTAKernel
[Xperia Z1 Original Android Development] pranii23:

I've been using a pair of JayBird bluebuds X daily since about two weeks, I don't seem to have this issue, but after some time using the device, the audio stream wil start stuttering and it becomes really annoying. People did tell me they had trouble hearing me as well.

A reboot solves the issue, but I found that setting the min CPU freq to 345MHz instead of 300MHz seems to help with this problem as well. I suspect there is a memory leak somewhere.

Are you sure that your earbuds are actually reconnecting (as in eye-witnessed it in the settings, or if you have the same buds as mine, you hear the voice saying "headphones connected" ?).

Please try to grab a logcat and a kmsg of this issue hapenning, I'd be interested in taking a look at it.

Hey guys m new to flashing kernels n my Xperia z1 is running [Nut] deodexed stock rom. 757 kitkat...

Can ne1 temme what do I need to flash this kernel..my bootloader is locked n I wanna know how do I flash this kernel..:) thanks in advance
[Xperia Z1 Original Android Development] wis3m0nkey:
U can't flash this kernel on stock ROM.

If u r going to flash any custom ROM (cm based hopefully) then u can flash this one.

If u want to keep stock ROM then have a look at doom kernel that one has plenty of customization but it's for unlocked bootloader.
[Xperia Z1 Original Android Development] 301stSpartan:
Actually Doom Kernel is only for UNLOCKED bootloaders. Still stock ROMs but bootloader must be unlocked. Not sure if that is just a typo in your post....

Sorry if it has been asked , but why does recent version doesn't have F2FS version of the kernel ?
[Xperia Z1 Original Android Development] husky69:
AFAIK the Dev didn't have the time to do the testing required yet.
[Xperia Z1 Original Android Development] ->---:
After many weeks of using the kernel I have to say it is very good for energy saving and swappiness. :good: The implementation of PhilzTouch with Androguide.fr's hint worked great. :highfive: But there are still some bugs in it.

- It is not possible to disable the phone. Every try leads to an automatic reboot.

- The cam stops working after a couple of hours running the phone. The app is freezing, the phone is rebooting or becoming laggy after trying to start the cam without success.

On some bugs I am unsure if they are from kernel or ROM. :confused: I am now on latest Pimped and PAC 0805

- After recharging, the power consuption is higher than before. This can just be solved with a restart.

- When connecting by docking interface the phone reboots by itself.

Thanks for the good work. :good: I hope there will be further developement. ;)

How can I enter the recovery. I try Vol. down and Vol. Up but it's boot normally
[Xperia Z1 Original Android Development] husky69:
I'm not sure whether it's kernel- or ROM-related, but I get a number of random reboots per day using the latest SlimKat ROM weekly build. Particularly during playing Ingress I get them apparently more frequent, I get the impression it mostly happens during high system or graphics load. Phone freezes then and reboots after a few seconds during which I can't do anything on screen.

Wasn't able to do a logcat 'in the field' so far :/

Any hints on what to look for?
[Xperia Z1 Original Android Development] wis3m0nkey:
Power down then power up.

While powering up press volume up 3 times when u see purple led. I keep pressing volume up multiple times until I see recovery.

If simple power up doesn't work then use volume up + power
[Xperia Z1 Original Android Development] Androguide.fr:
What's your PVS binning level? (You can see it in the CPU section of Pimp My Z1)

If you have a low PVS (< 3), maybe try to enable the voltage boost switch in the same section of the app, see if it helps.

With the OC implementation, we are using the voltage & frequency tables from the better version of the S800 (found in the nexus 5 for example), which has lower voltage requirements for any given frequency.

So depending on your CPU's binning level, it might not be able to handle the "stock" undervolting that comes with the kernel.

It could also not be that at all, but might be something to look-out for.

A logcat most likely won't be helpful, however you can grab the last kernel message (last_kmsg) to see what happened before the sudden reboot on the kernel side.

From a terminal or adb shell:

cat /proc/last_kmsg > /sdcard/last_kmsg.txt

I am not sure if you are right. Because:

The cam works normally after a reboot. But it does not after a couple of hours of running. As far as I understand his explaination his fix is for cam working/crashing directly after booting. There is nothing mentioned if this fix will work after 48 hours of running the phone without a reboot. But I asked him. Lets see what he is saying.
[Xperia Z1 Original Android Development] B1nny:
The problem he is talking about is the problem everyone is having. If yours is different it's probably an extra bug on top of this one, as this camera bug is present in all AOSP-based ROMs.

My camera also had a problem but with the camera fix, all OK.

I am in Resurrection Remix with pimped kernel and I have battery draining on screen off.

I have enabled the option on the kernel for working with only 1 core but when screen is off there is a lot of draining like 20% in 6 hours, wifi, 3g off

there is not any program that draining the battery so what is that?

Force shutdown your phone by pressing power button + volume down at the same time, then flash stock FTF with Flashtool.

I double checked the cam issue and now I am sure that KSM also is part of the problem. I used the fix in two cases. One with KSM deactivated and on the other activated.

Deactivated I randomly started the cam on 3 days including one recharging cycle without any problems.

Activated I started the cam 3 times within a no fully 24 hours time scale and on third try it crashed my system.

Sad thing because KSM really increases power saving in my typical use case.

Edit: I will now try a third way. Activated KSM and starting the fix every time before starting the cam.

Edit 2: After 2 tries the cam has stopped the phone completely. So it has definitive something to do with KSM too.

Sent from my Xperia Z1 using Forum Fiend v1.2.
[Xperia Z1 Original Android Development] Poesini:
I am curious of how you get power savings with KSM (and which settings) because I know it does the opposite
[Xperia Z1 Original Android Development] ->---:
I dont know, just the settings from the app. Maybe the merge of memory pages reduces RAM usage. and cells that are empty have not to be refreshed. Maybe its some kind of sideeffect. A deactivation of wakeloks or something. It is not always the case. But most of the times it seems to flatten the uncharging graph when it is on. From about 2-3% every 2 hours to about 1% or less.
[Xperia Z1 Original Android Development] Androguide.fr:
Well, first off it's totally useless to start the fix before starting the camera everytime, it could actually very well make things worse.

Just have it run once on boot and that's it.

On any device, if you have the "Can't connect to camera" dialog, only a reboot will fix it, no app or script can do anything about it.

I also highly doubt KSM would make you save battery, considering it needs to scan the memory for mergeable pages at a set interval (500ms by default).

But as you said, maybe the RAM savings make up for the battery usage of the scans, I don't know.

I'll do some testing but I've had KSM enabled (512 pages to scan, 500ms timer) all the time since the fix was found and I haven't had any issue whatsoever.

For people who didn't see it, I made a modified version of [MENTION=5194005]drklaw[/MENTION] 's camera fix app, you can learn more & download it from this post: http://xdaforums.com/showpost.php?p=52696903&postcount=23
[Xperia Z1 Original Android Development] ->---:
Thx, I already implemented your modified version into my system. :good:

I thought that the page merging possibly deactivates a part of the fix, so it would not work properly anymore. Therefore I tried the part with starting the fix everytime before cam. I also had a trial run when your modified cam fix was activated at startup, afterwards KSM activated with delay of pimp app. Because of expected troubles I deactivated KSM following and tried the cam, resulting in a black screen of death. I am no programmer so the only things I can do is to try, watch and note whats happening.

If the KSM does not have wakelocks it is only working during screen on? In that case I would not see any differences because I mostly just read or listen to music on my phone. Maybe the difference in power consumption just seemed as some, because of dirty reboots. I now do not see any differences without KSM to my best experiences with it.

Oriented on its power the XZ1 is a total overkill for what I need. But capacity of accu, RAM and SD-slot did not leave me any choice :D
