[Kernel][MM] Nautilus Kernel (26.3.A.1.33)

[zacharias.maladroit]

Nautilus Kernel for Xperia M4 Aqua​

Disclaimer:
By flashing this kernel you acknowledge that the developer is NOT liable for any loss of data, does NOT guarantee any fitness of functionality or non-harm to your phone. You are advised to backup the kernel and ROM before flashing any release which will overwrite the existing wlan module and will lead to broken WiFi when switching to e.g. Destiny kernel

Notes:
(thanks to dani020110 for idea of the thread/post structure and the kernel update script)

• 
  [*]THIS WILL WORK ONLY ON UNLOCKED BOOTLOADERS
• 26.3.A.1.33 Marshmallow only

Features:

• reduction of external kernel modules for less attack surface and better stability and protection
• lots of power-saving improvements/reductions in idle
• separate built WiFi module
• reduction of wakelock of WiFi driver
• ARP spoofing protection
• fuse-fixes
• in-built exfat driver (allows file-sizes on microSD of 2+ GB, better stability)
• mm: stability improvements
• several speedups in the core of the kernel
• writeback speedups / improvements
• attempts to pass SafetyNet
• zram with lz4 + z3fold allocator (NO internal memory fragmentation !) [Port from Xperia Z5]
• battery reduction in usage of Google Chrome & Chrome-based browsers (webkit / webview ?)
• in-built core_ctl driver (better reliability and stability)
• several improvements to the sound driver
• and other changes too small to mention separately
• optimized kernel config to speed up booting and slim down bloat
• 4.9 Linaro Toolchain
• optimized flags to allow further optimizations and better stability

Installation
M4 Aqua - Booting into fastboot mode

Getting into Fastboot - From the system (Android):

• adb reboot bootloader

Getting into Fastboot - Alternatively (while the phone is off):

• Shutdown down the phone (power it off):
• Connect the USB cable to your phone (your phone only !)
• Press the Volume DOWN button, keep it pressed ...
• Connect the other end of the USB cable to your PC/Mac, etc. and release the Volume DOWN button
• That should get you into fastboot mode (led is blue)
• Additionally you can check from your PC/Mac/Linux system if the device is there: fastboot devices

Finally - Flashing the Kernel (from Fastboot)
(WiFi might NOT work ! - thus flashing from TWRP/recovery is most times better (copying updated WiFi module))

• fastboot flash boot boot.img
• fastboot reboot

Flashing the Kernel via TWRP/Recovery
Booting into TWRP

• Press the Volume DOWN button, keep it pressed
• While pressing the Volume DOWN button also press the Power Button
• As soon as the screen turns on and you see the Sony logo ("splash"), release the Power Button - now ONLY keeping the Volume DOWN button pressed
• When you see the TWRP Logo ("splash" / screen), release the Volume DOWN button
• Once you are IN TWRP, the select the folder where the Kernel zip-file was copied to and flash ("install") it

(you must have flashed TWRP via fastboot flash recovery TWRP.img before to boot into recovery !)

The kernel currently is at a pretty early stage,

so bear with me - it's totally not where I want it to be (FauxSound, memory management improvements, even more battery/idle reductions, smoother operation, etc.)

but lack of time and focus on Xperia Z5* devices doesn't allow me to focus on it right now ...

First of all, thank you so much for diving into the development of this device. I was eager to get something like this from you and I honored to have it now and here.

At first, the kernel seems stable. There was quite a big lag at the first start up and it took a while for the WiFi to turn on but it's fine. I can't see any hotplug included in the kernel and SuperSU binaries are outdated. It seems like there isn't also undervolt and underclock included. The GPU idles at 400MHz which isn't quite power efficient. Overall it's good for a start. I also have a question which is for the touchscreen drivers for this phone. No matter the kernel, stock or custom, there are problems with the random shutting down of the touchscreen or going nuts (scrolling and pressing by itself randomly). I'm looking that the logs and it seems like that the cyttsp5 driver isn't functioning properly on the E2303 variant. I've attached dmesg and klog so you can take a look at it. Also, I'm not the only one with this problem, there are much more users in Q&A and on random forums and YouTube.

How can i backup current all of there (kernel, wlan,...)? before flash it

Backup your boot and system using twrp!

Can i use this for E2312 phone?
So thanks!

So thanks!

Of course you can

How does it compare to other kernels?
Does this kernel work with the Pexo rom?
I really REALLY want a kernel that has proper undervolt tables, because I can't stand my phone overheating randomly. Using Skymelon 9, it's alright but brings problems like overheating since it's running at higher frequency and the phone is already semi-snappy and I am not really gaming, since no games work that I like. For instance Shadowverse or Fate Grand Order. First game stutters and audio is distorted, while second game won't launch because phone is rooted.

No reason for it to not work with PexoROM

Mobile Data don't work on E2363 (dual) and kernel governor stay on "performance", all other is OK.

Keep your good work .

 

[LilBlinx]

Mobile Data don't work on E2363 (dual) and kernel governor stay on "performance", all other is OK.

Mobile data works here. For performance governor fix get the original init.qcom.post-boot.sh and put it in system/etc

 

[valyo_bg]

@DavidMKD Its shows that mobile data is enabled, but there is no icon for 3g/LTE and every app report that phone is offline when WiFi is OFF. Enabling and disabling of mobile data don't helps.
Which version of M4 you have? Thanks for "performance fix", I will try to find proper file to replace inside system/etc or you can share it?

Edit: I found correct file and replace it and now kernel governor is interactive , only problem with mobile data remain, hopefully @zacharias.maladroit will fix soon.

I think you are right about mobile data, it doesn't work here either

Thanks for your work

can you add low brightness mod please?

the original init.qcom.post_boot.sh file from E2333
https://www.mediafire.com/file/5mqc9n16fqwxan1/init.qcom.post_boot.rar
the original wlan.ko for SMK users
https://www.mediafire.com/file/4ejnzel0vacrji1/wlan.rar

 

[valyo_bg]

@zacharias.maladroit could you please fix mobile data problem? Mobile data is shown "enabled", but all apps report that they are offline.

 

[zacharias.maladroit]

Okay, updated the OP / first post with clearer instructions to get into Recovery,

LOT of folks are trying to mess with M4 Aqua users by posting WRONG instructions on how to get into fastboot or TWRP/recovery.

I thought I was (or Sony) going crazy with those differing Button combinations from M4 Aqua and Xperia Z5 but it's THE SAME !

fastboot:

Volume DOWN + connecting USB

Recovery:

Volume DOWN + Power button , Power release on Sony screen

No wonder people (or new starters) are having such a hard time to use this phone and start development for it (with that non-clarity , confusion and frustration)

Thanks for your work

Oh - been wondering what to make of the high brightness

Can you please point me to the modifications needed for it ?

With what tool or process the ramdisk/initramfs can be packed up again ?

@zacharias.maladroit could you please fix mobile data problem? Mobile data is shown "enabled", but all apps report that they are offline.

Consider it done (take a look at the kernel folder) [ https://drive.google.com/open?id=0BykGGWB96CBQUFhXbG5sRUZMMWM ]

The kernel is still experimental and more of a proof of concept:

The iddd (idd daemon - or close to that name) is crashing and force-closing continually (last time I checked),

thus I renamed and moved it to the internal storage so that the Android/init system deactivates it

Thanks to @dani020110 for pointing at the offending commit that would cause the crashing of the new kernel

@zacharias.maladroit I can't download from your link - message "not found, error 404" appear.

Edit: just download successfully from first page of this topic, as soon is tested will inform you about results, thank you.
