Xenomai is split in two parts: a kernel part and a userspace
|
part. Enabling this option automatically selects the Xenomai
|
package and helps in patching the Linux kernel built by
|
Buildroot with the Xenomai kernel part (ie Adeos/Ipipe).
|
|
You can find the currently supported kernel versions by
|
looking at the available patches in the Xenomai sources
|
tree: ksrc/arch/$(ARCH)/patches
|
|
However, it is recommended to use the latest version of the
|
Adeos/Ipipe patch available at
|
https://xenomai.org/downloads/ipipe/
|
|
Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
|
and PowerPC architectures.

depends on BR2_LINUX_KERNEL_EXT_XENOMAI
|
help
|
Optionally, explicitly specify where to find the Adeos
|
patch to use.
|
Examples:
|
https://xenomai.org/downloads/ipipe/v4.x/arm/ipipe-core-4.19.33-arm-2.patch
|
or /home/foo/ipipe-core-4.19.33-arm-2.patch
|
Please verify that your kernel version in Buildroot matches.

help

Linux Framebuffer drivers for small TFT LCD display modules,
|
e.g. Adafruit PiTFT displays for Raspberry Pi (this extra
|
package is only needed for linux kernels until v3.19, since
|
v4.0 the drivers are included in the staging area).
|
|
To enable fbtft, e.g. for Adafruit 2.8 PiTFT, enable the
|
following kernel configurations:
|
- CONFIG_SPI
|
- CONFIG_GPIOLIB
|
- CONFIG_FB
|
- CONFIG_FB_TFT
|
- CONFIG_FB_TFT_ILI9341

Aufs is split in two parts: a kernel part and a userspace
|
part. Enabling this option automatically selects the aufs
|
standalone (module) package and patches the Linux kernel
|
built by Buildroot with the aufs kernel part (ie fs/aufs).

It is important to use the correct branch of aufs-standalone.

select aufs5.x ).

The version you choose must match that of your kernel.
|
Usually, the sha1 of the cset you want to use; avoid using a
|
branch name as this yields non-reproducible builds.
