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.

@param[in] This A pointer to the EFI_DRIVER_HEALTH_PROTOCOL instance.

@param[in] ControllerHandle The handle of the controller to retrieve the health status
|

on. This is an optional parameter that may be NULL. If
|
|
this parameter is NULL, then the value of ChildHandle is
|
|
ignored, and the combined health status of all the devices
|
|
that the driver is managing is returned.
|

|
|
@param[in] ChildHandle The handle of the child controller to retrieve the health
|
|
status on. This is an optional parameter that may be NULL.
|
|
This parameter is ignored of ControllerHandle is NULL. It
|
|
will be NULL for device drivers. It will also be NULL for
|
|
bus drivers when an attempt is made to collect the health

|

attempt is made to collect the health status for a child
|
|
controller produced by the driver.

@param[out] HealthStatus A pointer to the health status that is returned by this
|
|
function. This is an optional parameter that may be NULL.
|
|
This parameter is ignored of ControllerHandle is NULL.
|
|
The health status for the controller specified by
|

|
|
with the controller specified by ControllerHandle and

|
MessageList is allocated by this function with the EFI Boot
|
|
Service AllocatePool(), and it is the caller's responsibility
|
|
to free MessageList with the EFI Boot Service FreePool().
|
|
Each message is specified by tuple of an EFI_HII_HANDLE and
|

an EFI_STRING_ID. The array of messages is terminated by tuple
|
|
containing a EFI_HII_HANDLE with a value of NULL. The
|
|
EFI_HII_STRING_PROTOCOL.GetString() function can be used to
|
|
retrieve the warning or error message as a Null-terminated
|
|
string in a specific language. Messages may be

returned for any of the HealthStatus values except
|
|
EfiDriverHealthStatusReconnectRequired and
|
|
EfiDriverHealthStatusRebootRequired.

|
|
|
@param[out] FormHiiHandle A pointer to the HII handle containing the HII form used when
|
|
configuration is required. The HII handle is associated with
|
|
the controller specified by ControllerHandle and ChildHandle.
|
|
If this is NULL, then no HII form is available. An HII handle
