I'm not exactly sure what this does yet, but thank you for developing for the NP.

Hey guys let me know of some features that you'd like implemented which I will consider adding.

I'd like a reboot option. =]

That is not a Kernel Option! It's a System thing ...

Do these filesystems actually function? I added these to my own kernel in testing and could get none of these working. I also added NTFS with write support and that did actually function correctly. I'd love to see CIFS or NFS working, along with F2FS and/or EXT2.

missed NTFS support adding that now, they should mount but selinux probably needs to be disabled because it blocks it

Here is v3 with NTFS support added in:

try and mount a NTFS drive and report back, also do setenforce 0 to disable selinux

Confirmed, NTFS works with my 4TB western digital mybook.

Kernel Update

Unleashed V4:
Zram set to 512MB as default on boot in fstab, was 90mb before which was pointless, now less redraws and better memory performance.

I just compiled the kernel for external usb webcam support:

Code:

CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L2_COMMON=y
CONFIG_USB_VIDEO_CLASS=y
CONFIG_VIDEO_MEDIA=y
CONFIG_V4L_USB_DRIVERS=y
CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y

but it would seem there is something missing in android tv that doesnt allow it

Excuse the noobness here, but with NTFS support, does this mean we can plug in an ntfs usb drive and it will be seen as system drive and install apps to it?

This would require some fstab editing on your part, just use stickmount and there may be an apps2sd app that could do it, or possibly a symlink, selinux will be need to set permissive as well

Kernel has been running great so far. Your efforts are appreciated. How is the kernel looking for overclocking?

I probably won't add overclocking for a while, the CPU is more powerful than anything ATM, for now I'm focusing on io/memory tweaks, since that seems to be the bottleneck, I will be adding as much as possible, and will keep this updated with the latest kernel code available.
