numactl unconditionally uses __atomic_fetch_and resulting in the
following build failure on architectures that need libatomic to provide
atomic intrinsics (e.g. microblaze) since commit
4ed540ddf5:
/nvmedata/autobuild/instance-5/output-1/host/lib/gcc/microblaze-buildroot-linux-uclibc/10.3.0/../../../../microblaze-buildroot-linux-uclibc/bin/ld: ./.libs/libnuma.a(libnuma.o): in function `numa_node_to_cpus_v1':
(.text+0x2a34): undefined reference to `__atomic_fetch_and_1'

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).
