The safe default is to let the platform force idle + devices since the kernel is already in a suspend state, and on + the chance that a driver does not properly quiesce bus-mastering + after a suspend callback the platform will handle it. However, + the activation might abort if, for example, platform firmware + determines that the activation time exceeds the max PCI-E + completion timeout. Since the platform does not know whether the + OS is running the activation from a suspend context it aborts, + but if the system owner trusts driver suspend callback to be + sufficient then 'firmware_activation_noidle' can be + enabled to bypass the activation abort.
