Worked on the intel/lkvs repository to deliver a robustness enhancement for Pstate test teardown, focusing on CPU management and system programming using Shell scripting. Developed logic to ensure that all CPUs offlined during power-state tests are reliably brought back online during teardown, addressing issues with test flakiness and improving the reliability of power-state validation in continuous integration environments. The solution involved hardening CPU hotplug handling within the test framework, resulting in more stable and maintainable test runs. This work contributed to improved test stability and reduced the likelihood of flaky failures, supporting more consistent CI outcomes for power-state testing.
