Typedef Documentation

typedef EFI_STATUS(EFIAPI * EFI_SIO_CONTROL_DISABLE)(IN CONST EFI_SIO_CONTROL_PROTOCOL *This)

Disable a logical ISA device.

This function disables a logical ISA device so that it no longer consumes system resources, such as memory, I/O, DMA and IRQ resources. Enough information must be available so that subsequent Enable() calls would properly reconfigure the device.

Parameters

This	A pointer to this instance of the EFI_SIO_CONTROL_PROTOCOL.

Return values

EFI_SUCCESS	The device is disabled successfully.
EFI_OUT_OF_RESOURCES	The device could not be disabled because there were insufficient resources either for the device itself or for the records needed to track the device.
EFI_ALREADY_STARTED	The device is already disabled.
EFI_UNSUPPORTED	The device cannot be disabled.

typedef EFI_STATUS(EFIAPI * EFI_SIO_CONTROL_ENABLE)(IN CONST EFI_SIO_CONTROL_PROTOCOL *This)

Enable an ISA-style device.

This function enables a logical ISA device and, if necessary, configures it to default settings, including memory, I/O, DMA and IRQ resources.

Parameters

This	A pointer to this instance of the EFI_SIO_CONTROL_PROTOCOL.

Return values

EFI_SUCCESS	The device is enabled successfully.
EFI_OUT_OF_RESOURCES	The device could not be enabled because there were insufficient resources either for the device itself or for the records needed to track the device.
EFI_ALREADY_STARTED	The device is already enabled.
EFI_UNSUPPORTED	The device cannot be enabled.
