[Buildroot] [PATCH 1/3] package/rt-tests: switch to the upstream repository

[Romain Naour]

rt-tests is not maintained from Clark Williams's repository anymore.

Signed-off-by: Romain Naour <romain.naour@gmail.com>
---
We missed some rt-tests release (v0.90 to v1.0).
Since v0.92 a release tarball is available at
https://www.kernel.org/pub/linux/utils/rt-tests so we
no longer need to clone the git repository.

[Buildroot] [PATCH 2/3] package/rt-tests: bump to 1.0

[Romain Naour]

Rebase patch 01 and 02 on v1.0
Remove upstream patches 03 and 04.

Switch to release tarball (.xz) and use BR2_KERNEL_MIRROR

Remove HASPYTHON since it has been removed from patch 01 and clear
PYLIB if PYTHON package is not selected.

Remove NPTL handling since the patch upstreamed by Alexey Brodkin
has been reverted [1]

Add hash file

-Subject: [PATCH] Makefile: allow building selected tests with non-NPTL
- toolchain
-
-Some architectures are still stuck with non-NPTL toolchains.
-These are for example ARC, Blackfin, Xtensa etc.
-
-Still rt-tests are very good benchmarks and it would be good to enable use of
-at least selected (those that will be built) tests on those architectures.
-
-This change makes it possible to only build subset of tests that don't require
-NPTL calls.
-
-By default behavior is not modified - all tests are built, but if one wants
-to build with non-NPTL toolchain just add "HAVE_NPTL=no" in command line
-or modify "HAVE_NPTL" variable right in Makefile and execute "make".
-
-This patch was submitted upstream:
-https://www.mail-archive.com/linux-kernel at vger.kernel.org/msg762958.html
-so as soon as it is accepted with the next version bump this patch should be
-removed.

[Buildroot] [PATCH 3/3] package/rt-tests: disable for musl toolchains

[Romain Naour]

The cyclictest program doesn't build with musl toolchains due to
several issues with a different implementation of the "struct sigevent"
from Glibc/uClibc and musl (similar to [1]).

The pi_stress program doesn't build with musl toolchains with the
following error since musl doesn't provide _POSIX_THREAD_PRIO_INHERIT
define even if musl have Priority Inheritance mutexes [2]:

src/pi_tests/pi_stress.c:78:2: error: #error "Can't run this test without PI Mutex support"
 #error "Can't run this test without PI Mutex support"

Since the fix for cyclictest is not trivial, disable rt-tests for musl
toolchains.

[Buildroot] [PATCH 2/3] package/rt-tests: bump to 1.0

[Thomas Petazzoni]

Hello,

One quick comment on this patch.

Please use "git format-patch -N" when generating patches for Buildroot
packages, in order to avoid the 1/2 and 2/2 specifications. These
specifications very quickly get wrong when we add or remove patches, so
we prefer not to have them.

Thanks,

Thomas

Agree, I just forgot about patch numbering.

I noticed a build issue with this new version of rt-tests [1] due to local
syscall number definition for the new kernel deadline scheduler on some
architectures. Upsteam added __NR_sched_setattr and __NR_sched_setattr
definition for common architectures (x86, x86_64, arm) and tile if not already
defined [2].

Maybe instead of adding missing syscall number, we can avoid building rt-tests
with toolchain compiled with too old kernel headers (i.e
BR2_TOOLCHAIN_EXTERNAL_HEADERS_3_14)

Thoughts ?

Best regards,
Romain

We can do that and then see if some people using older kernels complain
that rt-tests are not available for them.

Thanks,
