hermes - 💡(How to fix) Fix smoke_apu_4_jitter_rom_runs hang [1 comments, 1 participants]

The test should complete within a reasonable timeout or fail with a clear error message. The test hangs indefinitely without any output or error.

TL;DR

Investigate and adjust the timing/jitter handling in the test harness for smoke_apu_4_jitter_rom_runs to prevent indefinite hanging.

Guidance

• Review related issues #17463 and #17464 for similar APU smoke test hangs to identify potential common causes or solutions.
• Inspect the test harness code for smoke_apu_4_jitter_rom_runs to understand how timing and jitter are handled, focusing on potential areas that could lead to indefinite hanging.
• Consider adding logging or debugging statements to the test to gather more information about its state when it hangs, which could help pinpoint the issue.
• Evaluate the ROM execution timing and IRQ handling/flag timing as potential contributors to the hanging issue, based on the test's name and the pattern of similar issues.

Example

No specific code snippet can be provided without more details on the test harness and its implementation.

Notes

The solution may involve modifying the test harness to better handle timing and jitter, or adjusting the test's expectations for ROM execution and IRQ handling. Without more specific information about the test code and its environment, it's challenging to provide a precise fix.

Recommendation

Apply a workaround by adjusting the timing/jitter handling in the test harness, as this approach is likely to address the root cause of the issue based on the pattern of similar problems and the test's name.
