[Q] driver model for ara - Project Ara General

Hi,
I am a driver developer for linux kernel. I have been following ara's architecture and driver model, and it is interesting that they have chosen to introduce a user level driver model for modules. I understand that this is for module classes which are non-mainstream ( camera / audio etc), and also for unsupported features.
But WHY USER MODE DRIVERS? and why not kernel mode drivers?
Can anyone throw some light on this aspect?

What exactly is that topic?
Does that mean that the user can install the drivers?

Yes,
From the concept, it looks like the user can install drivers on the fly, presumably the ones supplied by the module maker. My question was why user mode drivers and why NOT kernel mode drivers...

I had hoped for a little explanation of the term User/Kernel Mode drivers....
I think if kernel mode refers to the drivers in the kernel structure, that you would have to compile the kernel everytime you put in a new module. That would not allow hot swapping, only if you let all drivers inside the kernel structure and besides that I doubt that'd be working, it created a great mess.
Just the thoughts of someone who is not really into kernel development or development of anything...

Multi window to custom firmware

Implement multi window impossible to custom firmware?
I'd like to see on your CM 11. It is strange that the developers did not realize Cyanogenmod this possibility in their firmware ...
Omnirom is what you are looking for.

CM 11 mail app on stock rom

Hi,
I have an i9500 GS4 and well i cant use CM as it has bugs that i can live with them, like BT problems (need it for work).
Now I'm really in a need of the mail app that come in CM. is it possible to install it on a stock based rom?
Thanks!
Most likely, yes.
Just download a cm rom and copy the email apk from /system/app to your s4 system/app and change permissions to rw-r--r--.
Reboot and test

I'd just try installing the apk normally first. I don't think it needs to be a system app.

[ROM][ VanirAOSP ][official][4.4.3][simple,clean,fast..]

We Sonic Developers have decided to give focus on the S4 active forums to make it a better place to live in :fingers-crossed: ... and here you go another work by us for you guys :good:​
Welcome to VanirAOSP. Our mission is to deliver a clean optimized version of Android with subtly improved versions of the features you love to as many devices as possible. we've tried to incorporate and improve our features in a way that makes them more cohesive to improve the overall user experience while correcting any performance regressions and improving functionality..
What to expect:
- This is not a McCopy ROM. What goes into our build is well thought-out and not a bunch of stuff duck taped together because we could.
- maximum optimization. We do our research. We test hard. We build thoroughly tested global optimizations including standard linaro.
- originality in our source. We generate a lot of new commits being features or general code improvements. We are open source to share and improve the community but we also try to make sure we offer a unique experience.
- aesthetics.. hopefully in your opinion
General features:
SU, busybox etc
stock mode - ability revert to stock AOSP code with the exception of a few custom features we chose to keep active
enhanced performance.. longer uptime with less slowdown
custom written CRON and init.d etc
UI and graphics improvements
custom navbar, navring, and hardware key features
halo (active display & lockscreen notifications are in review)
usability improvements like power reboot menu and sound
animation control
Improved Vanir keyboard
CM's profiles & quicksettings
additional quicksetting tiles
immersive mode
statusbar mods
clock & battery mods
lockscreen blur and other mods
soon to come -> quick cam and flash notifications
busybox, embedded root, init.d, cron etc
yatta yatta yatta
more to come when i feel like updating the op
Please help us continue developing, or simply just toss me some change for a coffee

I came from unofficial cm11.
Did a full wipe (dalvik, cache, factory reset).
Then installed VanirAOSP and gapps.
And everything running smooth.

Hi
How do I install this ROM?
I'm on official 4.2.2 without any modifications.
Can I just install recovery (CWM), wipe, and flash?
Thanks!
I9295 BTW

You have to root your phone first.
I used Chainfire's cf auto root.
There is a pretty good guide here: http://androidxda.com/root-samsung-galaxy-s4-active-gt-i9295
And then install a custom recovery
http://forum.xda-developers.com/showthread.php?t=2387980
Now you are ready to install custom ROM

I found a little "bug"
After OTA update (052514) when pressing the Vanir update tile in quick settings, it flips the screen to show notifications.
Before updating it took me to the update screen.
It's no big deal, just thought I'd report it

Same thing here. I never use it, so I didn't notice before.
EDIT: When trying to enable android debugging, i get Unfortunately, Settings has stopped.
When i go back in Developer options, debugging is enabled but doesn't work.

It takes 38 Seconds to power on my device , isn't that too long for simple rom ???

People with the gsm selection bug ... This bug is because the rom source doesn't allow for changing such things so we had to fix a lot of conflicts ... Just go up with selections s little bit and choose other modes until it shows gsm , the modes mashed up ....USB debugging issue is there because maybe u haven't done a data wipe , if not please do one a give me results ... MY DEVICE IS UNDER MAINTENANCE ... Thank you people for using ROMs .

[Q] Tablet UI possible?

I've googled and tried the xposed framework but have not gotten it to work. I know tablet UI was removed from kitkat but i think it would be really cool for our devices. Any devs or feedback on this? Thanks
