- Tests to see if this driver supports a given controller. If a child device is provided,

-
- 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().
- Because 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
- must support a protocol interface that supplies
- 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.
-
- @retval EFI_SUCCESS The device specified by ControllerHandle and
- RemainingDevicePath is supported by the driver specified by This.
- @retval EFI_ALREADY_STARTED The device specified by ControllerHandle and

+ AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+ Because 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
