Linuxium kernel in android x86?

[adam dubuque]

I am still trying to get my sound working for baytrail. I loaded linuxium ubuntu and everything worked, sound, bluetooth you name it.
Is it possible to install android x86 6.0 and use the kernel from linuxium to get everything working?
If so can you tell me how to swap kernels and where it's located after the android install. I usually partition an ext4 on my C: to install android.

Otherwise is there any way to get this sound working on baytrail???

Thank you again

So bad news is that we can't simply install new kernel on android like we would on a regular linux, no clue to what steps take, but without a package manager some things may be left missing. As far as I can tell, same for drivers too, and very little can be changed even on a rooted device.
Good news is that if its in fact working on linuxium kernel, changes are likely to be patched or added into some form on the android_x86 releases.
So how did you manage to test those features? My tablet has barely any working hardware (display control, power management, touch, battery, who else knows more), and this could possibly bring some life to it again.

[Henri Koivuneva]

Good news that it works!

The Android version of Linux kernel is so different from mainline Linux that it simply cannot work. There are many things specific to Android in it so that's why it isn't "plug and play".

However, if the patches he has applied to his linuxium kernel, then built it and shared, are available somewhere in .patch files, anyone could apply them to the Android-x86 kernel. I've tried asking him for the patches a few times but he doesn't even reply. Sure, he links to a GitHub repo where his modified kernel resides, but the patches aren't available there, at least they weren't when I last checked in December I think.

So if anyone can get the patches that he uses and send them here, I could make you a test build with them for Android-x86 Nougat/Bliss-x86/LineageOS x86. Then if everything works and the patches don't break stuff for other devices, we can ask the Android-x86 developers to merge them too!

However, any of that won't be possible if:
1. The patches aren't merged into mainline kernel (from where they come down to Android-x86 eventually) for some reason
2. OR they're not available as standalone patch files which we can use to patch the kernel ourselves
For example when someone creates a patch that will be added to mainline kernel, it'll still take quite a while to get there because it needs verification, testing, review etc. so a patch made now might get to kernel 4.12 or so.

Last year I spent some months tracking down different patches from mailing lists etc and applied them with both patch files and manual editing, we got some stuff working, but not even near enough and it also took a lot of time because of the need to find the fixes, manually find the correct rows in the code, copy over the new stuff, build and test, see that something went wrong, go through the code again, build again, etc... I built myself a fast PC for also this purpose so full clean builds now take about 40 minutes to complete, making the whole process faster.

So if you or anyone else can find and share the patch files used in that linuxium Ubuntu kernel it would be great! Then we could have bigger possibilities of getting Android-x86 for bay trail and maybe cherry trail working better. That would also mean that the fixes and additions could be added to Android-x86 itself, thus letting many more people enjoy the great stuff this amazing project brings. Chuwi tablets etc would get a whole new life...

Somewhat off-topic: Ubuntu 17.04 with kernel 4.10 is the FIRST Linux ever that has booted straight away with no hacking needed on my PC (due to NVIDIA cards like now GTX 1080). It's incredible what the open source community can do.

[adam dubuque]

I will help with this as much as I can thank you for offering to help

[Guilherme Furst]

Found that Linuxium release to try it out, its was surprisingly good, quick boot, responsive, wifi and audio indeed working, battery was a bit confused but at least it detected. Things that still didn't seem to  work are, power management, display touch and brightness.
At the very least it really looks promising, so please do keep us posted if you find out the source of these patches, as they could be useful not only on Android but other linux systems as well.

[youling 257]

very simply ， Linux version 4.11.0-rc1-android-x86 (root@localhost) (gcc version 6.3.0 20170221 (Ubuntu 6.3.0-8ubuntu1) ) #2 SMP PREEMPT Mon Mar 6 18:12:02 CST 2017 ，first time porting 4.11 rc1 to Android x86

Hello Youling,
Is this latest kernel from Maurossi?, Too fast for me :-) I'm yet testing your directions for 4.8.17, but AFAIK 4.11 will be the first kernel with baytrail issues fixed OOTB. Have you tried it?

Regarding linuxium patches, we can get a list of patches referenced in he's blog entries, are public, but not he's own patches, at least in form of a patch file.

[youling 257]

by myself，isn't Maurossi，I download linux-4.11-rc1.tar.xz ，Mar 6 18:12:02 CST  .  4.11 upstream merged all the sound patchs and necessary battery patch ，/sys/class/power_supply/axp288_fuel_gauge . first CONFIG_ACPI_BATTERY=m and /system/etc/modules.blacklist battery .  what OOTB ?

I can't thank you guys enough for your help. I am praying big time that this works out. I have ubuntu on my machine in hopes to help but I am a complete nuub when it comes to compiling kernals. I have not done even 1 yet. But I am desperate. I will continue to do my best and find patches and if I can figure it out help to apply them. By the way what baytrail machines do you have? I have the Efun Nextbook Flex 11 z3735f
Now dual booting windows 10 and Ubuntu linuxium.

There are two Ubuntu kernel branches I have been working on in the BlissRoms-x86 repo. Ubuntu-4.10.0-5.7-blissified has most of the Cherry Trail patches, zesty-kernel-4.10.0-11.13-blissified has all the patches that made it to their Zesty release I think, & ubuntu-4.11-blissified is tracking their dev branch and pulling in various patches from other sources too. I am still tracking more down and slowly building them both up. You guys are free to use these as well :)

[Henri Koivuneva]

Wow Jon, awesome! Can't wait to get to try that out hopefully this weekend! Thank you!

Nothing is more important than adjusting brightness and silead ，I still use 4.8.17 ，no kernel developer solved bay trail silead and adjust brightness at 4.9 kernel later . 4.9 kernel is longterm，but silead not work . battery state is no problem on my 4.8.17 kernel and my Android，on post-fs ，before start healthd service，runing battery script .

Great News!!! So can someone please build an android x86 with kernal 4.11

[adam dubuque]

This version called ANDEX (wich the developer is charging $9) supposedly runs on almost any machine including bay and cherry trail.
https://sourceforge.net/projects/andex/

[adam dubuque]

This looks very interesting to
Running a full android distros from a USB or sd card or dual boot with android and Linux

Can anyone confirm this

[Giam Teck Choon]

What is the difference if you create a multiboot USB with Windows OS installation, Android-x86 (32bits and 64bits), Remix OS (32bits and 64bits), Rescue CD ISOs and other Linux ISOs etc... ?  Example I custom one just for playing with different OS and doing rescue....

Sorry for this off-topic.  I will stop for now.

[adam dubuque]

It was created by Ian morrison the same guy who created linuxium so I am hoping that the distros will work with baytrail

[Georgios Kourachanis]

Hi

The patches that linuxium has used on his github for the ubuntu kernel version 4.10.0-10.12 are the ones that I attach on this message.

I created them by cloning Ubuntu's original tree and comparing versus linuxium's tree. Of course with the correct versions (tags+branches).

 thank you 

[adam dubuque]

YOU DID IT!!! EVERYTHING WORKS!!!!
SOUND,BLUETOOTH,SCREEN DIMMING,YOU NAME IT AND IT WORKS
I LOVE YOU, YOU ARE MY SAVIOR
AFTER ALMOST 2 YEARS IT WORKS!!!
THANK YOU SOOOOOO MUCH

[adam dubuque]

Oh yea mine isn't slow, I used extended 4 format and it's lightning fast I have it installed and not live not sure if that helps but mine is perfect

[adam dubuque]

Ok I may have spoke to soon.
My volume is pretty low at full volume and headphones do not work.
So I figured since bluetooth is working I'll use a Bluetooth connector for my headphones but it connected and immidiatly crashed so that's not working really either.
Please don't think I am complaining there is sound even if it is low which makes it usable now. And reboot also worked. The things that aren't working are a great deal closer now to working then ever, so again thank you, I hope this continues and we can improve on this because it is so awesome and so hopefully and this will help the tolhousands of people with batty trail machines. I would be curious to know how well this might work on the cherry trails also

[adam dubuque]

One more correction I attempted to restart and boot back into android and now it just gets stuck on the cyan android marshmallow head flashing, I've waited and waited but it won't boot.
Alt+f1 says
Modprobe: couldn't probe module 'fs-cpuset'
'F2fs'
No controlling tty: open /dev/tty: no such device or address
Warning won't have full job control

[Jamie Earp]

headset detection isnt working yet, although you can switch manually to headphones, ill add the script in the next build for you.

im currently looking into the sound issue as it is quiet for me too

setting volume on boot doesnt work unless you run 

alsa_amixer -c0 sset 'Speaker' 30

that fixes the volume.

bt im not sure why it crashes for you as its fine here,

also i dont have boot issues maybe you did something?

if its stuck then did you install g-apps

bluetooth works perfect for me,

[Dan Mirescu]

I too tested the build posted by Jamie Earp on a Baytrail tablet:
- wifi working, albeit a bit slower than its general performance on Windows
- no battery status report
- touchscreen not working at all (out of the box, at least)
- volume keys working
- built in speaker works, but sound is low at high volume
- no screen dimming
- headphone jack not working
- the power button displays the "power off / restart / airplane mode" menu, which is nice but I'm still hoping for the ability to put / take out the tablet into/from standby when pressing the button.
- screen auto rotates, but it's off by 90 degrees in most cases (portrait tablet -> landscape display and vice versa)
- another nice thing to have would be to automatically turn the display off when the tablet cover is closed (based on magnetic detection)
I think this thing works when using Windows 10 (I hope I'm not mistaken) so it's theoretically possible
- bluetooth: discovers devices but crashes when trying to connect headphones. The headphones detect the connection then they immediately lose it.

[Dan Mirescu]

Does your touchscreen work with the build posted by Jamie Earp?
Also, does it work with the official Android x86_64 6.0 r1/r2 builds?

On my Baytrail tablet it doesn't seem to work out of the box. I found a way to kind of make it work on the official build, but it's not ideal (bad detection on screen edges, no multitouch)

[Jamie Earp]

also if your dual booting make sure you tun fast startup off in windows or do a full shutdown as hibernate or fast boot might conflict with android booting up

I think you known the sound problem Android x86 4.4 kernel z3770/z3740，when Plug in headphones ，headphone work，but speaker not auto close，so they are used alsamixer(root) app close speaker，the reason is bytrt5640.state for 4.4 kernel .

[adam dubuque]

I am dual booting with windows so I will turn off fast boot and see how that goes. I used alsa mixer and went into speaker which was at 17 I turned it to 30 and the sound is perfect now. The Bluetooth does connect to my phone but not really sure what it does. I don't really care, my sound works and if I can fix the booting issue I'll be great. Also I went into developer to root you have to reset app permissions or something I'll report back about that and turning off fast boot.
My touchscreen does work perfectly, my auto rotate works, my wifi is screwy (says not connected to Internet a lot), but mostly works. I'm going to see what I can do to fix the issues. I can't compile kernals but I can repair issues when their done. I'll keep posting

[Jose Luis s]

Hello.

good news that finally we're close to have a almost out of the box android-x86 for our tablets, probably we'll never getthere but we are close. So far I get to have a semi-working cm13 (thanks youling for your help), only have issues now with my touchscreen (silead), With Youling set of patches we can get the same results as with 4.11-rcx. In my case when silead issues with newer kernels were solved probably we have a working kernel for baytrails (some scripts will be needed), anyway not sure if you get working things like volume rocker buttons, do you?

Jamie, thanks for sharing.

BTW you are using the linuxium kernel and you only activated the android options in config, do you?

[adam dubuque]

Oh yea volume rocker buttons do work holding power and release gives power options.

Does anyone know how to add gapps to this?....

[adam dubuque]

I'm sorry to say turning off fast boot didn't fix my boot freeze dilemma. It seems like my wifi will crash and it will no longer connect to Internet then after that when I reboot it will no longer boot past the cyan alien

After further testing I think it might be the live wallpaper that is freezing bootup.
I have a sort of fix for my wifi issue.
I went into developer and turned on more boot up optionsnow when the wifi won't work I can soft reboot and it fixes it

[adam dubuque]

Nope not the live wallpaper I just tried a wifi fix app no live wallpaper and it rebooted when I clicked fix then I got stuck in boot again I am starting to think wifi and booting issue are linked.
Also I noticed in the build prop or was it init.is can't remember but the wifi channel didn't have anything next to it, it was blank

[adam dubuque]

ok WOW! So I went from not having sound to having sound and now not booting after the second bootup.....
Now what???

theres a reason the wifi driver is in the staging folder, its buggy theres a long way to go for this to be considered stable.

OpengApps is part of my build but its causing booting problems, so for now its disabled

Root will work havto disable and re enable root in dev settings

Yea wifi is a bit screwy, i think its down to the framework

Fine. Indeed I don't have any sound issue on my
cherrytrail (Surface 3, yes I added bytcrrt5640.state)
and baytrail tablets (T100).
But I didn't hear any positive report from others yet.

I mean, please try our kernel-4.9 branch
to see if it works:
https://osdn.net/projects/android-x86/scm/git/kernel/commits?branch=kernel-4.9

If not, try to figure out what are missed.

Note we are not officially switch to kernel-4.9
(there are still some issues to be resolved but
I have no time recently)
but it's good enough to try.

You are free to try newer upstream kernel but
the project would stick with the LTS android kernel
which is maintained by Google
(for better compatibility)

[Jamie Earp]

Ill try it tonight and get back to you

[adam dubuque]

I believe that my reboot issue if grom using the reboot/power off options. I think as long as I power down by holding the power button, it works. I will confirm and report back.
I am extremely happy and great full for your amazing success. Thank you
I really hope you continue your efforts and make baytrail a part of android x86

[adam dubuque]

ok confirmed, as long as i shut down holding power i do not have the reboot freeze issue.
Im also thinking the wifi issue only happens when using the pull down options it apears that as long as i use options in settings it wont screw up and only have connect no internet. i will continue to test it and report back.
I have to turn the sound up in alsa mixer every reboot (im fine with this and very happy, its not haard to do) just wondring if anyone knows a setting that I can make it perminant?

[Jose Luis s]

Hi again.

In my case the results are not so good. Sound working YES..... volume rocker working YES (a step forward), power button works partially, 1 touch brings power menu but does not switch off the screen, touchscreen does NOT work at all (as expected, silead in a 4.9 kernel in baytrail), dimming not workinig at all, and battery indicator not working, and YES BT is working properly.

similar result (but bT) with the latest maurossi 4.10 isos.

Thanks a lot anyway.

[adam dubuque]

I'm great everything is fairly usable. Please let me know if there is anything I can do to continue to help with this.
Jamie earp you should open a new thread letting baytrail owners know what you've done for us. If you do please link it here or let me know I will subscribe. If your too busy let me know and I can start one linking to this thread for the download if you'd like.Thank you again....
By the way which baytrail tablets do you have?

@jose Luis S which baytrail unit are you using?

[adam dubuque]

I tried the alsa_amixer command in terminal but it came back "'Speaker'" unknown command
I'm using the alsamixer.apk app perhaps it might be why not sure....
I used the su command before trying also

[Jamie Earp]

Well the screen will not turn off and the device wont sleep as baytrail power managment ic (pmic) is not very sell implemented yet, it needs more work,

Im not finished developing for baytrail and ill be here untill it is fully working

To note:
silead touch is a known issue with 4.9 kernel 1 of my tabs has mssl1680 so work ill look into it soon.

Button issues are last on my list as devices are all different and dependant on manufacturers.

Rotate issues can be messed with in /etc/init.sh the script grabs the dmi model number and applies rotation settings based on device model.

Sleep wont work untill intel pull their finger out of their A£@? This is related to why screen wont turn off, (pmic) also baytrail hasnt got s3 state.

Adam glad youve figured out the niggles, its where in upto for now, when i progress you will all know, maybe ill start a thread at xda
My username is onejay09
Ill keep you all posted

[adam dubuque]

Awesome! Yea XDA would be great I'm adambomb_13 over there
I can confirm my WiFi is working perfect as long as I use settings to apply it
If I use the pull down quick settings it will screw it up but I can soft reboot to fix it if that happens and the soft reboot doesn't affect booting like reboot or power off does.

[Jose Luis s]

3 different chuwi tablets, same result:
vx8 3G bussines edition
v89 dual 64GB
hi8

[Jamie Earp]

When silead is working in the 4.9 kernel
If your familiar with linux id sudgest you goto
Www.Github.com/Onitake
And make your own android firmware for the silead touchscreen
All info is on his github

[Jamie Earp]

Ok great ill sort it out tonight

[Jose Luis s]

Hello Jamie.

Sure, Silead has a known issue with newer kernels (even 4.11rc2 tested in my case) and seem to involve some other changes from my understanding (Youling has reported many times the patchwork threads related). I've made my firmware following onitake directions some weeks ago, but it's ACPI driver does not work also. I get silead,ko driver working till 4.8.17 (as Youling reported).

In Maurossi 4.11 rc2 isos I found power button 1 touch switch off the screen (well not really true because led backlight is still on but black screen) and 1 large touch brings out the power menu (maybe 4.11 rc2 improvement, don't know) also battery is reported properly.
Instead BT does not work (is a simple patch)

For me 4.11 rc2 is almost perfect but Silead Support.

Thanks

Thanks Youling I was not aware...., anyway double click is not the same as Long press, with linuxium isos I get power menu with long press..... I'll review build.prop in both....

I agree is more important the STR issue, but Android is not meant for STR isn't it? I'd love to have STR in android. Suspend in Android is not the same a STR. AFAIK.

[youling 257]

what are your dual os Android ia 4.4.4 Standby time ? when Standby，what Battery consumption ? battery can use many days .

Android x86 early suspend，not working on bay trail-CR (z3735f、z3735G) .

Sure in Android-ia 4.4.4, on Standby, my tablets stands for days, but this is exactly not in STR mode, or at least that was my thought.

Is Early Suspend =  STR?

[Jamie Earp]

do we have access to the kernel source for any baytrail device running 4.4.4?

[youling 257]

you use 4.10，Failed to get MCLK from pmc_plt_clk_3: -2 and in1_map ，upstream 4.10 missed some patch . 4.10 isn't OOTB .

upstream 4.11，OOTB for sound，my Insyde tablet no longer need patch for sound .
your chuwi tablet is Insyde ?

Ok.

Yes my Chuwi tablets are all Insyde.

I've just tested Maurossi isos with 4.11-rc2 and yes sound working as well.

[youling 257]

use this bytcrrt5640.state for Insyde device，You will be pleasantly surprised .

Thanks Youling

[Andy]

I've just downloaded and tried Jamie Earp's cm iso on my Acer Switch 10.

- Sound is working (low volume but it doesn't matter)
- WiFi is working (I just need to manually connect my AP)
- Screen rotation is NOT working (no sensors detected, apart the useless light sensor)
- Some games work (e.g. Clash Royale, Minecraft PE) many others don't
- Video decoding is working with sound, at least those on Youtube accessed by Firefox

Anyway something strange has happened since many apps that worked at a first attempt
after some minutes refuse to start or produce a black screen.
The system becomes slower and a cold reboot is needed.

I'm looking for a solution to install OpenGapps (if any) and I'm looking forward to trying
also Maurossi's iso (where can I find it?).

TIA,
Andy

@Andy: Many of the Android games will not work on x86, unfortunately, because they contain native code bits that do not work on the generic x86 platform that Android x86 supports.

[Jamie Earp]

Idnt that what native bridge is for?

In settings/native bridge

Hi.
I've been testing BT more deeply and found some issues with the BT manager app. it randomly crashes when some pairing process. Most pairing with BT headsets,with or wihout handsfree profile. Some progress here?

B.R

[Jon West]

Try also adding Tag to the list of include programs to build with if you haven't already.

[Jose Luis s]

Hi Jamie.

Did you applied the ta100 dsdt.hex file in the kernel? is this the reason why is the volume rocker working in your iso? I guess that the patching in this dsdt file is more or less standard for more devices.

Thanks

theres a reason the wifi driver is in the staging folder, its buggy theres a long way to go for this to be considered stable.

Nope not the live wallpaper I just tried a wifi fix app no live wallpaper and it rebooted when I clicked fix then I got stuck in boot again I am starting to think wifi and booting issue are linked.
Also I noticed in the build prop or was it init.is can't remember but the wifi channel didn't have anything next to it, it was blank

[Jamie Earp]

Initially i was using a dsdr.hex in an attempt to fix bluetooth as my dsdt had 2 dt devices so i removed and compiled with kernel, but i removed it after realising that it made no difference once bt was working,

Volume rockers working is probably because of the irq fix? Maybe or acpi changes in the kernel  as it used to fail to read acpi correctly,

If i was you i would wait untill the kernel get some much needed updates regarding baytrail

Ill come back to the project in a few months to see whats new regarding fixes for baytrail

[adam dubuque]

From what I can see these are some major breakthroughs for baytrail users. I really wish some more people would team up and get a github.com thread running and the androidx86 programmers would use these finds and impliment them into the new kernels and releases. There is so much potential here, it's just been years since anyone actually found the fix everyone involved probably gave up hope. If word got out, this could be huge. Like I said this is a breakthrough that no one until now has even had any success

Where can I find Linuxium kernel patches ?

Linuxium patches, are more or less unnecessary now, only add support to wifi/BT in stagging, (sound is supported in kernel 4,11 rcx in most tablets with Baytrail/cherrytrail) only add .state files and some files to have BT support and so. kernel is impoving a lot to have support to Baytrail/Cherrytrail, also there is more patches from other sources to have suspend and brightness support. In my case the issue is silead driver not working in 4.11 kernels.

I'm curious if Mauro Rossi has new isos with kernel 4.11 (final) with these improvments, as he has this new kernel in his repo.
