OK. VERY GOOD! Thanks. But i don't have Pine64 board now. Waiting my board... If you have Pine64 board you can try run test like here: https://rt.wiki.kernel.org/index.php/Cyclictest

If the kernel build a successful, try to make the tests.

Hi Artyom,

the green coloured settings are already enabled, the red coloured settings cannot be enabled due to different reasons:
- they depend on a certain architecture or minimal kernel version
- they depend on additional patches being applied first

Cheers
Uli

You use "make menuconfig" when configuring your kernel? I find some info about (as i undestand minimal kernel configuration):
--------------------------------------------------------------------------------------------
Required parameters for configuring realtime kernel?
Kernel 2.6.x:
CONFIG_PREEMPT=y
CONFIG_PREEMPT_RT=y
Kernel 3.x:
CONFIG_PREEMPT=y
CONFIG_PREEMPT_RT_BASE=y
CONFIG_PREEMPT_RT_FULL=y
Optional parameters for configuring realtime kernel, but they affect realtime performance?
CONFIG_HIGH_RES_TIMERS=y
------------------------------------------------------------------------------------------------------------------
More you can find here: https://rt.wiki.kernel.org/index.php/Frequently_Asked_Questions#Kernel_3.x:_2

As I undestand CONFIG_PREEMPT_RT_FULL must present in our kernel...

only CONFIG_PREEMPT_RT_BASE is offered at this time (and enabled). You may get in touch with chlorisdroid, he managed to build a RT enabled Linux kernel for the ODROID -C2.

I've updated the description how to  build a custom kernel on the PINE64 in order to reflect @longsleeps recent changes on U-Boot .

For the RT kernel just take my Github repository instead, so

Code:

git clone --depth 1 --single-branch -b pine64-hacks-1.2 https://github.com/umiddelb/linux-pine64-rt.git
curl -sSL https://github.com/longsleep/build-pine64-image/raw/master/blobs/pine64.dts > linux-pine64/arch/arm64/boot/dts/sun50i-a64-pine64-plus.dts
make sun50iw1p1smp_linux_defconfig
make menuconfig
make clean
make -j 4 Image sun50i-a64-pine64-plus.dtb modules

and so on.

Yesterday I wrote chloris droid. Waiting for an answer... I also plan to write RT patch developers. Furthermore Now I recompile the kernel Raspberry Pi 2 to integrate ARM Gator. How to deal with him, we will integrate ARM Gator in Pne64 core. 

There did not seem difficult now. You in? )))
