Frequently Asked Questions

1

Under what conditions can this issue occur?

It occurs when amdgpu_debugfs_test_ib_show() resumes an AMD GPU and its attempt to acquire the reset-domain write semaphore is interrupted. The interrupted error path then leaks the runtime PM reference, leaving the GPU awake.

2

What is the impact if the vulnerable path is triggered?

The affected GPU can remain powered instead of returning to runtime autosuspend because its runtime PM reference is not released. This is a resource and power-management leak rather than a described memory-safety or privilege-escalation issue.

3

What should be done if the fix cannot be applied immediately?

The provided information does not identify a configuration workaround. Mitigation would require avoiding the interrupted amdgpu debugfs test-IB path until a kernel containing the runtime PM reference cleanup is deployed.
