14.3 Repair() Implementation
The Repair()
service attempts repair operations on a driver-managed
controller or a child the driver has produced. This service is not allowed to
use any of the console-I/Orelated protocols. Instead, the status of the repair
operation is returned to the caller. The Repair()
service supports an
optional parameter called ProgressNotification that may be NULL
. The caller
may pass in a notification function to Repair()
so the caller can inform the
user of the progress during extended repair operations. If a repair operation
takes a short period of time to execute, ProgressNotification may be ignored.
If the repair operation takes an extended period of time to execute, the UEFI
Driver should periodically call the function specified by
ProgressNotification with Value and Limit parameters expressing the
amount of repair work currently completed. The caller may choose to log or
display the progress of the repair operation as well as the final results of
the repair operation.
