rt-tests doesn't build with some "old" toolchains due to missing local syscall number definition for the new kernel deadline scheduler on some architectures. Upsteam added __NR_sched_setattr and __NR_sched_setattr definition only for common architectures (x86, x86_64, arm) and tile if not already defined [1]. Instead of adding missing syscall number, avoid building rt-tests with toolchain compiled with too old kernel headers (i.e !BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_14) At runtime, a 3.14 kernel must be used otherwise these syscall are not available.

Set of utilities for testing the real-time behaviour of a
|
|
Linux system.
|
|
|
|
All tools are simple C programs with no dependencies, except
|
|
the hwlatdetect utility, which is a Python script and
|
|
therefore requires the Python interpreter. It will only be
|
|
installed if a Python interpreter has been selected in the
|
|
Buildroot configuration.
|
|
|
|
Note that this package requires a toolchain built with the
|
|
NPTL implementation of the pthread API (this is always the
|
|
case with glibc toolchains, but may not necessarily be the
|
|
case with uClibc toolchains, since the thread implementation
|
|
is configurable).
