# Xenomai
config BR2_LINUX_KERNEL_EXT_XENOMAI
bool "Adeos/Xenomai Real-time patch"
depends on BR2_TOOLCHAIN_HAS_THREADS

select BR2_PACKAGE_XENOMAI
help
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
http://download.gna.org/adeos/patches
Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
and PowerPC architectures.

string "Path for Adeos patch file"
help
Optionally, explicitly specify the Adeos patch to use.
Download it at http://download.gna.org/adeos/patches
and verify that your kernel version in buildroot matches.
# RTAI
config BR2_LINUX_KERNEL_EXT_RTAI
bool "RTAI Real-time patch"

help
RTAI Kernel part.
# fbtft
config BR2_LINUX_KERNEL_EXT_FBTFT
bool "FB TFT drivers"
select BR2_PACKAGE_FBTFT
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
