Hi,
The meeting minutes are summarized below. Thanks for attending.
MINUTES:
Vendor remote lab is interesting to openEuler for wide hardware coverage.
-
Leverage existing Linaro LKFT Lab + remote lab -
e.g, NXP remote lab (shared by NXP, Linaro, KernelCI) -
CompassCI also has plan for remote lab support
CompassCI also has the capability for bisecting support (the algorithm can be universal to both kernel and user space applications). LKP itself doesn’t have the bisecting capability. TuxSuite is focusing mainly on the kernel part.
Paolo: is it functional or performance bisecting in CompassCI?
Fengguang: currently functional, performance support will be added later
CompassCI starts from upstream, and then downstream (so not only downstream kernel).
Arch Linux package build is used by CompassCI, so it is easy to add different kernel builds.
Scale testing with QEMU (e.g, run openEuler on Kunpeng 920, and run multiple QEMU instances on openEuler), and it can be deployed via remote lab. Fengguang: it is nice.
17+ machines in CompassCI lab now. Maybe start with 1 machine for prototyping (the dispatcher can run on the same machine for QEMU case).
Anmar: the dispatcher is fully dockerized now, there should be no big issue to run on openEuler.
Paolo: modularization can be helpful to merge the benefits of both
Paolo: Is the part for performance bisecting ready in CompassCI?
Fengguang: not yet
Paolo: maybe we can work together to have some common solution to avoid reinventing the wheel. It’s under design for LKFT so it’s a good place for us to collaborate.
Fengguang: Focus is on build now then the benchmark testing.
Anmar: the Linaro team and Fengguang to connect later on to make sure the tool is useful for both CI systems.
Questions and Answers:
-
Q. Can LKP run without having to install packages or tests, only the job definitions (scripts) ? If we can run tests without having to install the pre-req every time, that will speed up testing if we use a rootfs that has all its pre-req installed. -
A. Compass CI has cpio archives it uses to overlay the tests dependencies to speed the test runs. These overlays are pre-built and available to the Compass-CI system
-
Q. We want to get a better understanding of the compare functionality -
A. compare fetches different results and presents them. Nothing more.
-
Q. What are the plans for alignment with upstream LKP? By examining the https://github.com/fengguang/lkp-tests and comparing it to https://github.com/intel/lkp-tests.git, it seems the trees started diverging in March 2020. -
A. Fengguang’s LKP-tests repo is periodically re-based on the upstream LKP-tests repo every couple of months. There is effort to push some of the changes back upstream but been minimal so far. Most of the tests run on Arm64 so from a testing perspective, Arm64 is well represented. It’s also not clear if LKP will accept many patches at the moment. However, a discussion needs to happen with the upstream at some point in time.
-
Q. How difficult is it to modularise the following LKP components: -
Monitors -
Tests -
Test-plans -
Email reports -
Harmonizing output -
Functional -
Benchmark -
Regression detection -
A. LKP is already modularized and functions as a pipeline.
