- Sends an ATA command to an ATA device that is attached to the ATA controller. This function

- and the non-blocking I/O functionality is optional.
-
- @param[in] Port The port number of the ATA device to send the command.
- @param[in] PortMultiplierPort The port multiplier port number of the ATA device to send the command.
- If there is no port multiplier, then specify 0.
- @param[in, out] Packet A pointer to the ATA command to send to the ATA device specified by Port
- and PortMultiplierPort.
- @param[in] Instance Pointer to the ATA_ATAPI_PASS_THRU_INSTANCE.
- @param[in] Task Optional. Pointer to the ATA_NONBLOCK_TASK
- used by non-blocking mode.
-
- @retval EFI_SUCCESS The ATA command was sent by the host. For
- bi-directional commands, InTransferLength bytes
- were transferred from InDataBuffer. For
- write and bi-directional commands, OutTransferLength
- bytes were transferred by OutDataBuffer.
- @retval EFI_BAD_BUFFER_SIZE The ATA command was not executed. The number
- of bytes that could be transferred is returned
- in InTransferLength. For write and bi-directional
- commands, OutTransferLength bytes were transferred
- by OutDataBuffer.
- @retval EFI_NOT_READY The ATA command could not be sent because
- there are too many ATA commands already
- queued. The caller may retry again later.
- @retval EFI_DEVICE_ERROR A device error occurred while attempting
- to send the ATA command.
- @retval EFI_INVALID_PARAMETER Port, PortMultiplierPort, or the contents
- of Acb are invalid. The ATA command was
- not sent, so no additional status information
- is available.

- 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.

- must support a protocol interface that supplies

- 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.
