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

-
- @param[in] Port The port number of the ATA device to send the command.

- 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

- bytes were transferred by OutDataBuffer.

- 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

- 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

- 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

- Get IDE i/o port registers' base addresses by mode.
-
- In 'Compatibility' mode, use fixed addresses.
- In Native-PCI mode, get base addresses from BARs in the PCI IDE controller's
- Configuration Space.
-
- The steps to get IDE i/o port registers' base addresses for each channel
- as follows:
-
- 1. Examine the Programming Interface byte of the Class Code fields in PCI IDE
- controller's Configuration Space to determine the operating mode.
-
- 2. a) In 'Compatibility' mode, use fixed addresses shown in the Table 1 below.

- | | Command Block | Control Block |
- | Channel | Registers | Registers |
- |___________|_______________|_______________|
- | Primary | 1F0h - 1F7h | 3F6h - 3F7h |
- |___________|_______________|_______________|
- | Secondary | 170h - 177h | 376h - 377h |
- |___________|_______________|_______________|
-
- Table 1. Compatibility resource mappings
-
- b) In Native-PCI mode, IDE registers are mapped into IO space using the BARs
- in IDE controller's PCI Configuration Space, shown in the Table 2 below.
