UEFI Platform to Driver Configuration Protocol is defined in UEFI specification.
|
||
|
|
|
||
|
|
This is a protocol that is optionally produced by the platform and optionally consumed
|
||
|
|
by a UEFI Driver in its Start() function. This protocol allows the driver to receive
|
||
|
|
configuration information as part of being started.

/**
|
||
|
|
The UEFI driver must call Query early in the Start() function
|
||
|
|
before any time consuming operations are performed. If
|
||
|
|
ChildHandle is NULL the driver is requesting information from
|
||
|
|
the platform about the ControllerHandle that is being started.
|
||
|
|
Information returned from Query may lead to the drivers Start()
|
||
|
|
function failing.
|
||
|
|
If the UEFI driver is a bus driver and producing a ChildHandle,
|
||
|
|
the driver must call Query after the child handle has been created
|
||
|
|
and an EFI_DEVICE_PATH_PROTOCOL has been placed on that handle,
|
||
|
|
but before any time consuming operation is performed. If information
|
||
|
|
return by Query may lead the driver to decide to not create the
|
||
|
|
ChildHandle. The driver must then cleanup and remove the ChildHandle
|
||
|
|
from the system.
|
||
|
|
The UEFI driver repeatedly calls Query, processes the information
|
||
|
|
returned by the platform, and calls Response passing in the
|
||
|
|
arguments returned from Query. The Instance value passed into
|
||
|
|
Response must be the same value passed into the corresponding
|
||
|
|
call to Query. The UEFI driver must continuously call Query and
|
||
|
|
Response until EFI_NOT_FOUND is returned by Query.
|
||
|
|
If the UEFI driver does not recognize the ParameterTypeGuid, it
|
||
|
|
calls Response with a ConfigurationAction of
|
||
|
|
EfiPlatformConfigurationActionUnsupportedGuid. The UEFI driver
|
||
|
|
must then continue calling Query and Response until EFI_NOT_FOUND
|
||
|
|
is returned by Query. This gives the platform an opportunity to
|
||
|
|
pass additional configuration settings using a different
|
||
|
|
ParameterTypeGuid that may be supported by the driver.
|
||
|
|
An Instance value of zero means return the first ParameterBlock
|
||
|
|
in the set of unprocessed parameter blocks. The driver should
|
||
|
|
increment the Instance value by one for each successive call to Query.
|
||
|
|
|
||
|
|
@param This A pointer to the EFI_PLATFORM_TO_DRIVER_CONFIGURATION_PROTOCOL instance.
|
||
|
|
|
||
|
|
@param ControllerHandle The handle the platform will return
|
||
|
|
configuration information about.
|
||
|
|
|
||
|
|
@param ChildHandle The handle of the child controller to
|
||
|
|
return information on. This is an optional
|
||
|
|
parameter that may be NULL. It will be
|
||
|
|
NULL for device drivers and for bus
|
||
|
|
drivers that attempt to get options for
|
||
|
|
the bus controller. It will not be NULL
|
||
|
|
for a bus driver that attempts to get
|
||
|
|
options for one of its child controllers.
|
||
|
|
|
||
|
|
|
||
|
|
@param Instance Pointer to the Instance value. Zero means
|
||
|
|
return the first query data. The caller should
|
||
|
|
increment this value by one each time to retrieve
|
||
|
|
successive data.
|
||
|
|
|
||
|
|
@param ParameterTypeGuid An EFI_GUID that defines the contents
|
||
|
|
of ParameterBlock. UEFI drivers must
|
||
|
|
use the ParameterTypeGuid to determine
|
||
|
|
how to parse the ParameterBlock. The caller
|
||
|
|
should not attempt to free ParameterTypeGuid.
|
||
|
|
|
||
|
|
@param ParameterBlock The platform returns a pointer to the
|
||
|
|
ParameterBlock structure which
|
||
|
|
contains details about the
|
||
|
|
configuration parameters specific to
|
||
|
|
the ParameterTypeGuid. This structure
|
||
|
|
is defined based on the protocol and
|
||
|
|
may be different for different
|
||
|
|
protocols. UEFI driver decodes this
|
||
|
|
structure and its contents based on
|
||
|
|
ParameterTypeGuid. ParameterBlock is
|
||
|
|
allocated by the platform and the
|
||
|
|
platform is responsible for freeing
|
||
|
|
the ParameterBlock after Result is
|
||
|
|
called.
|
||
|
|
|
||
|
|
@param ParameterBlockSize The platform returns the size of
|
||
|
|
the ParameterBlock in bytes.
|
||
|
|
|
||
|
|
|
||
|
|
@retval EFI_SUCCESS The platform return parameter
|
||
|
|
information for ControllerHandle.

@retval EFI_NOT_FOUND No more unread Instance exists.

|

|
|
|
||
|

@retval EFI_INVALID_PARAMETER Instance is NULL.
|

information for the controller

specified by ControllerHandle and

ChildHandle.
