Nothing about this is GMUX specific. I agree, but there needs to be another variable. Using pm_runtime_suspended or using any other pm function will not work, as amdgpu_pmops_runtime_resume also requires hardware access and even though hardware is accessable by then pm core will show that its runtime suspended.
