Tests to see if this driver supports a given controller. If a child device is provided,
|
|
it further tests to see if this driver supports creating a handle for the specified child device.
|
|
|
|
This function checks to see if the driver specified by This supports the device specified by
|
|
ControllerHandle. Drivers will typically use the device path attached to
|
|
ControllerHandle and/or the services from the bus I/O abstraction attached to
|
|
ControllerHandle to determine if the driver supports ControllerHandle. This function
|
|
may be called many times during platform initialization. In order to reduce boot times, the tests
|
|
performed by this function must be very small, and take as little time as possible to execute. This
|
|
function must not change the state of any hardware devices, and this function must be aware that the
|
|
device specified by ControllerHandle may already be managed by the same driver or a
|
|
different driver. This function must match its calls to AllocatePages() with FreePages(),
|
|
AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
|
|
Since ControllerHandle may have been previously started by the same driver, if a protocol is
|
|
already in the opened state, then it must not be closed with CloseProtocol(). This is required
|
|
to guarantee the state of ControllerHandle is not modified by this function.

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

@param[in] ControllerHandle The handle of the controller to test. This handle

an I/O abstraction to the driver.

@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
|
|
parameter is ignored by device drivers, and is optional for bus
|
|
drivers. For bus drivers, if this parameter is not NULL, then
|
|
the bus driver must determine if the bus controller specified
|

by ControllerHandle and the child controller specified
|
|
by RemainingDevicePath are both supported by this

bus driver.
|

Send TPer Reset command to reset eDrive to lock all protected bands.

Typically, there are 2 mechanism for resetting eDrive. They are:
|
|
1. TPer Reset through IEEE 1667 protocol.
|
|
2. TPer Reset through native TCG protocol.
|
|
This routine will detect what protocol the attached eDrive comform to, TCG or

IEEE 1667 protocol. Then send out TPer Reset command separately.
