Hello, A script with patches together a kernel, ipipe and xenomai kernel drivers. Result is the packages to install the kernel image.
A buildroot configuration will build the rootfs, without * using the identical kernel version (different patch level) * using headers that were used for building the kernel. * using the kernel .config Instead, buildroot DL a different Linux kernel version by itself and used those headers. I don`t think they are needed outside of glibc, but I am not sure. Further, buildroot will create a "staging" installation for building further tools, including those using Xenomai APIs. So, is this generally safe or something to avoid. I haven't ran into any issues yet. Differences in the basic include files (same kernel version) seem to be rather trivial diff -burN /tmp/header/include/asm-generic/mman-common.h /tmp/patched/usr/include/asm-generic/mman-common.h --- /tmp/header/include/asm-generic/mman-common.h 2018-02-06 14:26:43.657405976 +0100 +++ /tmp/patched/usr/include/asm-generic/mman-common.h 2018-02-06 13:43:26.000000000 +0100 @@ -19,6 +19,9 @@ #define MAP_TYPE 0x0f /* Mask for type of mapping */ #define MAP_FIXED 0x10 /* Interpret addr exactly */ #define MAP_ANONYMOUS 0x20 /* don't use a file */ +#ifndef MAP_BRK +# define MAP_BRK 0 +#endif #ifdef CONFIG_MMAP_ALLOW_UNINITIALIZED # define MAP_UNINITIALIZED 0x4000000 /* For anonymous mmap, memory could be uninitialized */ #else diff -burN /tmp/header/include/asm-generic/resource.h /tmp/patched/usr/include/asm-generic/resource.h --- /tmp/header/include/asm-generic/resource.h 2018-02-06 14:26:43.689406277 +0100 +++ /tmp/patched/usr/include/asm-generic/resource.h 2018-02-06 13:43:26.000000000 +0100 @@ -57,5 +57,13 @@ # define RLIM_INFINITY (~0UL) #endif +/* + * Limit the stack by to some sane default: root can always + * increase this limit if needed.. 8MB seems reasonable. + */ +#ifndef _STK_LIM +# define _STK_LIM (8*1024*1024) +#endif + #endif /* _ASM_GENERIC_RESOURCE_H */ diff -burN /tmp/header/include/linux/resource.h /tmp/patched/usr/include/linux/resource.h --- /tmp/header/include/linux/resource.h 2018-02-06 14:26:46.433432104 +0100 +++ /tmp/patched/usr/include/linux/resource.h 2018-02-06 13:43:28.000000000 +0100 @@ -59,12 +59,6 @@ #define PRIO_USER 2 /* - * Limit the stack by to some sane default: root can always - * increase this limit if needed.. 8MB seems reasonable. - */ -#define _STK_LIM (8*1024*1024) - -/* * GPG2 wants 64kB of mlocked memory, to make sure pass phrases * and other sensitive information are never written to disk. */ Kind regards Norbert Lange AT-DES ANDRITZ HYDRO GmbH Eibesbrunnergasse 20 1120 Wien, Austria APhone.: +43 50805 56684 .
