Development of real-time kernel.

This thread created for all those interested in the development of real-time kernel. real-time Linux kernel will allow to extend the scope of possible application Pine64. For example in avionics (autopilot for drone), automation systems, etc.
This is link to pure kernel 3.10.65 with PREEMPT RT patch installed. Apparently a patch is installed correctly.

What i must do next to prepare this kernel for testing on pine64?

You need to review the files with the suffix .rej to find out why a specific hunk failed, e.g run a diff between the mainline and the BSP version of the file.

@umiddelb
Can you tell me, What is the difference between BSP kernel and mainline kernel? What i must do with mainline kernel to get BSP kernel?

The BSP (= Board Support Package) kernel contains patches provided by Allwinner to make the stock Linux kernel run on their SoC. Some of theses patches may interfere with the RT patches.

You can download the mainline 3.10.65 kernel here and run diffs against the BSP kernel for the files indicated above.
Then you need to identify the sections affected by the RT patch in the BSP kernel or run the patch against the mainline sources and compare the files mentioned above before and after applying the RT patch with their BSP kernel counterpart.

I've re-mediated the rejected hunks and this time the kernel builds and boots up nicely. You can download the the kernel binary tar archive here.

Unpack with:
Code:
curl -sSL https://github.com/umiddelb/z2d/blob/master/kernel/linux-3.10.65-2-pine64-rt69+-p64.tar.xz?raw=true | sudo tar --numeric-owner -C / -xpJf -

You may find the kernel sources here.
