- is useful in the case of drives that lie about their capabilities. An example
- is when the IDE device fails to accept the timing modes that are calculated
- by the IDE controller driver based on the response to the Identify Drive command.
- If the driver entity does not want to limit the ATA timing modes and leave that
- decision to the IDE controller driver, it can either not call this function for
- the given device or call this function and set the Valid flag to FALSE for all
- modes that are listed in EFI_ATA_COLLECTIVE_MODE.
- The driver entity may disqualify modes for a device in any order and any number
- of times.
- This function can be called multiple times to invalidate multiple modes of the
- same type (e.g., Programmed Input/Output [PIO] modes 3 and 4). See the ATA/ATAPI
- specification for more information on PIO modes.
- For Serial ATA (SATA) controllers, this member function can be used to disqualify

- Returns the information about the optimum modes for the specified IDE device.
- This function is used by the driver entity to obtain the optimum ATA modes for

- while calculating the mode:
- The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()
- The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- for all the devices that belong to an enumeration group before calling
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.
- The IDE controller driver will use controller- and possibly platform-specific
- algorithms to arrive at SupportedModes. The IDE controller may base its
- decision on user preferences and other considerations as well. This function
- may be called multiple times because the driver entity may renegotiate the mode
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().
- The driver entity may collect timing information for various devices in any
- order. The driver entity is responsible for making sure that all the dependencies
- are satisfied. For example, the SupportedModes information for device A that
- was previously returned may become stale after a call to
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
- The buffer SupportedModes is allocated by the callee because the caller does
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
- is defined in a way that allows for future extensibility and can be of variable
- length. This memory pool should be deallocated by the caller when it is no
- longer necessary.
- The IDE controller driver for a Serial ATA (SATA) controller can use this
- member function to force a lower speed (first-generation [Gen1] speeds on a

- to recalculate modes. This function allows the driver entity and the IDE
- controller driver to negotiate the timings on a per-device basis. This function
- is useful in the case of drives that lie about their capabilities. An example
- is when the IDE device fails to accept the timing modes that are calculated
- by the IDE controller driver based on the response to the Identify Drive command.
- If the driver entity does not want to limit the ATA timing modes and leave that
- decision to the IDE controller driver, it can either not call this function for
- the given device or call this function and set the Valid flag to FALSE for all
- modes that are listed in EFI_ATA_COLLECTIVE_MODE.
- The driver entity may disqualify modes for a device in any order and any number
- of times.
- This function can be called multiple times to invalidate multiple modes of the

- specification for more information on PIO modes.
- For Serial ATA (SATA) controllers, this member function can be used to disqualify

- Returns the information about the optimum modes for the specified IDE device.
- This function is used by the driver entity to obtain the optimum ATA modes for

- while calculating the mode:
- The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()
- The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- for all the devices that belong to an enumeration group before calling
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.
- The IDE controller driver will use controller- and possibly platform-specific
- algorithms to arrive at SupportedModes. The IDE controller may base its
- decision on user preferences and other considerations as well. This function
- may be called multiple times because the driver entity may renegotiate the mode
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().
- The driver entity may collect timing information for various devices in any
- order. The driver entity is responsible for making sure that all the dependencies
- are satisfied. For example, the SupportedModes information for device A that
- was previously returned may become stale after a call to
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
- The buffer SupportedModes is allocated by the callee because the caller does
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
- is defined in a way that allows for future extensibility and can be of variable
- length. This memory pool should be deallocated by the caller when it is no
- longer necessary.
- The IDE controller driver for a Serial ATA (SATA) controller can use this
- member function to force a lower speed (first-generation [Gen1] speeds on a
