Since the ARM AArch64 toolchain toolchain bump [1], the TestPppd fail
at runtime since ttyppp0 and ttyppp1 interfaces were not created
properly:
pppd[87]: pppd 2.5.2 started by root, uid 0
pppd[87]: Baud rate for /dev/ttyppp1 is 0; need explicit baud rate
The new toolchain uses glibc 2.42 that include a rework in termios
"implement arbitrary and split speeds in termios" to support BOTHER
[2]. This rework seems to conflict with pppd workaround [3] introduced
when BOTHER was not supported in Glibc.
Fix this by setting the baudrate on pppd command line (we already set
this baudrate on socat command line).

We have our own GitLab-CI runner, but with only one we can't run many
jobs in parallel so it takes a very long time before all the tests have
completed. In addition, if that runner goes down, we have nothing at
all.
GitLab offers the following machine types for hosted runners on Linux
x86-64 [1]. The default is the "small" runner. Using a larger runner
increases the "Cost factor" [2].
For opensource projects, the Cost factor is reduced to 0.5 (1 minute per
2 minutes of job time) whatever the runner type.
Runner Tag vCPUs Memory Storage Cost factor (OSS)
saas-linux-small-amd64 (default) 2 8 GB 30 GB 1 (0.5)
saas-linux-medium-amd64 4 16 GB 50 GB 2 (0.5)
saas-linux-large-amd64 (Premium and Ultimate only) 8 32 GB 100 GB 3 (0.5)
saas-linux-xlarge-amd64 (Premium and Ultimate only) 16 64 GB 200 GB 6 (0.5)
saas-linux-2xlarge-amd64 (Premium and Ultimate only) 32 128 GB 200 GB 12 (0.5)
Compute minutes consumed by a job is calculated by:
Job duration / 60 * Cost factor
(Job duration: The time, in seconds, that a job took to run, not
including time spent in the created or pending statuses.)
Thanks to the GitLab OSS program [3], Buildroot benefits from a free
Ultimate subscription and can use GitLab shared runners tagged with
saas-linux-{large, xlarge, 2xlarge}-amd64. In addition, we receive
50,000 free runner minutes per month.
In order to use one of those tags in Buildroot GitLab-CI jobs, we have
to classify all tests by resource requirement, to make sure the job
doesn't fail because it times out or has insufficient memory or disk
space. While we usually shouldn't use the largest runner for
everything, we can use larger runner without cost penalty thanks to
the cost factor reduced to 0.5 for opensource projects. This will
reduce the CI minutes consumed by a CPU intensive job.
First we introduce some new templates used to add the corresponding
runner tag to a runtime test job (reusing the GitLab terminology).
.runner-{small,medium,large,xlarge,2xlarge}
Most of our tests are fast (checkpackage, test_external_bootlin...), so
saas-linux-small-amd64 runner tag is enough. Default to this tag if
nothing else is specified.
Add a comment next to the test class to provide the runner tag.
This runner tag is retrieved when generating the
generated-gitlab-ci.yml file used to create the child pipeline where
the runtime test jobs are executed.
We use the list of runtime tests returned by node2:
"tests.boot.test_edk2.TestEdk2.test_run"
We convert each element of this list to get the path to the test source
file and the name of the test:
"support/testing/tests/boot/test_edk2.py"
TestEdk2
With that, we can grep into the test source file to retrieve the runner
tag placed one line above the test class:
# GitLab-runner: large
class TestEdk2(infra.basetest.BRTest):
Once the runner tag is retrieved, it's used to use the corresponding
runner template to the runtime test job:
tests.boot.test_edk2.TestEdk2.test_run: { extends: [ .runtime_test_base, .runner-large ]}
GitLab runners hosted by the Buildroot project should be able to run
any jobs, so they should be tagged with Gitlab runner tags
(saas-linux-{small,medium,large,xlarge,2xlarge}-amd64).
A specific runner tag "buildroot-runner" can be used to allow running
a job only on such runners.
If a test can't be executed by any shared GitLab-CI runners, we have
to use a runner owned by the Buildroot project. In this case we have
to use a specific template ".runner-buildroot-runner-only" in order to
add the specific runner tag "buildroot-runner" to the job running the
test. There is no such runtime test at the moment.
The proposed classification is based on a previous pipeline analysis
[5]:
- Tests lasting more than 3 hours will use 2xlarge runners.
- Tests lasting more than 2 hours will use xlarge runners.
- Tests lasting more than 1 hours will use large runners.
- Tests building a kernel or a toolchain will use medium runners.
- All other tests will use small runners when possible.
CI minute cost estimate:
tests.package.test_clang.TestClangCompilerRT.test_run lasts 4h25 on the
Buildroot runner. If we this duration for 2xlarge runners, the CI
minute consumed would be:
(15900 / 60) * 0.5 = 133
With 6 jobs using a 2xlarge runners we used ~795 CI minutes.
tests.package.test_kmscube.TestKmsCube.test_run list 2h04 on the
Buildroot runner. If we this duration for xlarge runners, the CI
minute consumed would be:
(7440 / 60) * 0.5 = 62
With 4 jobs using a xlarge runners we used ~248 CI minutes.
tests.package.test_weston.TestWeston.test_run last 1h15 on th
Buildroot runner. If we this duration for large runners, the CI
minute consumed would be:
(4500 / 60) * 0.5 = 37.5
With 28 jobs using a large runners we used ~1050 CI minutes.
tests.package.test_gstreamer1.TestGstreamer1.test_run last 46min on the
Buildroot runner. If we this duration for large runners, the CI
minute consumed would be:
(2760 / 60) * 0.5 = 23
With 31 jobs using a medium runners we used ~713 CI minutes.
tests.package.test_python.TestPython3Py.test_run last 13min on the
Buildroot runner. If we this duration for large runners, the CI
minute consumed would be:
(780 / 60) * 0.5 = 6.5
With 691 jobs using a medium runners we used ~4491 CI minutes.
In total, one pipeline for the runtime tests cost ~7297 CI minutes.
After a first try [6], we are actually using 8000 CI minutes per
pipeline.
We run such pipeline once a week (on Monday), one for each Buildroot
releases every 3 month, one for each stable and LTS release per month,
and one for each release candidate (3).
Worst case (release month):
(4 weeks + 1 release + 1 stable + 1 LTS + 3 release candidate) * 8000 CI
minutes: 80000 CI minutes / 50000.
So we would spend the minutes very quickly in the worst case scenario.
We have to keep one pipeline under 5000 CI minutes.

for ARM (32-bit) are now organized into subdirectories. For the

subdirectory.

This commit bump the kernel version of this docker test (5.4->6.18), and thus
fixes several issues preventing the Docker Compose runtime test from
succeeding due to this bump:
Kernel Infrastructure:
The Docker daemon failed to start because the 'nat' table could not
be initialized. This was due to missing legacy Netfilter support.
- Enable CONFIG_NETFILTER_XTABLES_LEGACY to support iptables nat table.
- Enable CONFIG_NAMESPACES and CONFIG_USER_NS for container isolation.
- Enable CONFIG_TUN and CONFIG_VETH for container networking.
- Enable CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC for easier debugging.
Build Fixes:
While building the kernel tools, the libelf header was missing because
objtool was not handled correctly for this kernel version. This resulted
in a fatal error: "gelf.h: No such file or directory".
- Select BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y to build host-libelf.
Resources and Stability:
The previous 512MB of RAM was tight for the stack (Kernel +
Docker + Containerd + Python), potentially leading to Out-Of-Memory kills.
Idem for the disk size for Docker images/layers storage.
- Increase QEMU RAM to 1024MB (-m 1024M).
- Increase rootfs size to 1024MB.
- Switch to EXT4 (BR2_TARGET_ROOTFS_EXT2_4=y) for better stability
and modern feature support required by Docker's storage drivers.
Test Script Adjustments:
- Update rootfs path in the test script to point to rootfs.ext4.
