1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this

same driver's Start() function.

2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid
|
|

EFI_HANDLE. In addition, all of these handles must have been created in this driver's
|
|

Start() function, and the Start() function must have called OpenProtocol() on
|
|
||||||
ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.

|
|

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

@param[in] ControllerHandle A handle to the device being stopped. The handle must
|
|
||||||
support a bus specific I/O protocol for the driver
|
|
||||||
to use to stop the device.
|
|
||||||
@param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.
|

This function is called by DiscoverIdeDevice() during its device

Its main purpose is to get enough information for the device media
|
|

to fill in the Media data structure of the Block I/O Protocol interface.
|
|
||||||
|
|
||||||
There are 5 steps to reach such objective:
|
|
||||||
1. Sends out the ATAPI Identify Command to the specified device.
|
|
||||||
Only ATAPI device responses to this command. If the command succeeds,
|
|
||||||
it returns the Identify data structure which filled with information
|
|
||||||
about the device. Since the ATAPI device contains removable media,
|
|
||||||
the only meaningful information is the device module name.
|
|
||||||
2. Sends out ATAPI Inquiry Packet Command to the specified device.
|
|
||||||
This command will return inquiry data of the device, which contains
|
|
||||||
the device type information.
|
|
||||||
3. Allocate sense data space for future use. We don't detect the media
|
|
||||||
presence here to improvement boot performance, especially when CD
|
|
||||||
media is present. The media detection will be performed just before
|
|
||||||
each BLK_IO read/write

|
||||||

|
||||||

|
|
