CXL spec 3.1 section 8.2.9.9.11.1 describes the device patrol scrub control feature. The device patrol scrub proactively locates and makes corrections to errors in regular cycle. The patrol scrub control allows the request to configure patrol scrub input configurations. The patrol scrub control allows the requester to specify the number of hours for which the patrol scrub cycles must be completed, provided that the requested number is not less than the minimum number of hours for the patrol scrub cycle that the device is capable of. In addition, the patrol scrub controls allow the host to disable and enable the feature in case disabling of the feature is needed for other purposes such as performance-aware operations which require the background operations to be turned off.
