Schedtool is the definitive interface to Linux's scheduler.

Signed-off-by Angelo Compagnucci <[email protected]>

Thanks for your patch.

The two syscall "__NR_sched_setattr" and "__NR_sched_getattr" has been defined for most architectures since kernel 3.14 but schedtool redefine them for x86_64, i386 and arm even if they are already available in linux/unistd.h... (see syscall_magic.h)

So schedtool should depend on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_14 except for microblaze (BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_15), aarch64 (BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_17) and blackfin (BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_1) otherwise it will break.

Obviously, it needs a kernel that implement these syscall.

Can you check if schedtool can really be used on these architectures.

Best regards,
Romain Naour
