Hello,

KernelCI is hosting a bi-weekly call on Thursday to discuss improvements to existing upstream tests, the development of new tests to increase kernel testing coverage, and the enablement of these tests in KernelCI.

Below is a list of the tests the community has been working on and their latest status updates, as discussed in the last meeting held on 2024-11-03:

*Missing devices kselftest*

- Proposing new kselftest to report devices that go missing in the system (v2): https://lore.kernel.org/all/20240928-kselftest-dev-exist-v2-1-fab07de6b80b@c... - Sent v2 addressing feedback received on the RFCv1 and during the session at LPC 2024: https://www.youtube.com/live/kcr8NXEbzcg?si=QWBvJAOjj7tg264o&t=11283

*Boot time test*

- RFC: https://lore.kernel.org/all/20240725110622.96301-1-laura.nao@collabora.com/T... - Discussed proposal at LPC2024: https://www.youtube.com/live/8XQwzUZxLK4?feature=shared&t=16944 - Planning on preparing v2, based on feedback received in the session - Suggestions for improvements and additional features include: exploring bootloader tracing via pre-filled ftrace buffers, adding support for specifying variance values on a per-event basis, investigating the use of ftrace histograms for initcalls

*Device testing documentation*

- Patch: https://lore.kernel.org/all/20241001-kselftest-device-docs-v1-1-be28b70dd855... - Submitted documentation on device testing, detailing the types of kselftests available, their requirements, and the coverage they provide. The goal is to guide users in selecting the appropriate tests for their devices.

*GPIO test*

- RFC: https://lore.kernel.org/all/20240909-kselftest-gpio-set-get-config-v1-0-16a0... - Proposed a new kselftest to verify the GPIO driver functionality. The test uses a YAML-based test plan that specifies the configurations to be checked. It sets each pin configuration and retrieves it to ensure they match. Currently, the test only verifies bias settings, but it can be easily extended to cover additional pin configurations.

Please reply to this thread if you'd like to join the call or discuss any of the topics further. We look forward to collaborating with the community to improve upstream tests and expand coverage to more areas of interest within the kernel.

Best regards,

Laura Nao
