EFI Driver Health Protocol definitions.
|
||
|
|
|
||
|
|
When installed, the Driver Health Protocol produces a collection of services that allow
|
||
|
|
the health status for a controller to be retrieved. If a controller is not in a usable
|
||
|
|
state, status messages may be reported to the user, repair operations can be invoked,
|
||
|
|
and the user may be asked to make software and/or hardware configuration changes.
|
||
|
|
|
||
|
|
The Driver Health Protocol is optionally produced by a driver that follows the
|
||
|
|
EFI Driver Model. If an EFI Driver needs to report health status to the platform,
|
||
|
|
provide warning or error messages to the user, perform length repair operations,
|
||
|
|
or request the user to make hardware or software configuration changes, then the
|
||
|
|
Driver Health Protocol must be produced.
|
||
|
|
|
||
|
|
A controller that is managed by driver that follows the EFI Driver Model and
|
||
|
|
produces the Driver Health Protocol must report the current health of the
|
||
|
|
controllers that the driver is currently managing. The controller can initially
|
||
|
|
be healthy, failed, require repair, or require configuration. If a controller
|
||
|
|
requires configuration, and the user make configuration changes, the controller
|
||
|
|
may then need to be reconnected or the system may need to be rebooted for the
|
||
|
|
configuration changes to take affect.

|
retrieve the warning or error message as a Null-terminated
|
