GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS structure (gpioclx.h)
The GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS structure describes a bank of general-purpose I/O (GPIO) pins whose hardware state is to be saved or restored.
Syntax
typedef struct _GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS {
BANK_ID BankId;
ULONG State;
GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_FLAGS Flags;
} GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS, *PGPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS;
Members
BankId
The identifier for this bank of GPIO pins. If N is the number of banks in the GPIO controller, BankId is an integer in the range 0 to N–1. The GPIO framework extension (GpioClx) previously obtained the number of banks in the controller from the CLIENT_QueryControllerBasicInformation event callback function. For more information, see Remarks in CLIENT_CONTROLLER_BASIC_INFORMATION.
State
The target component power state. A save operation occurs before the specified bank of GPIO pins makes the transition from the F0 (fully on) state to the target component power state, Fx. A restore operation occurs after the bank makes the transition from Fx to F0.
Flags
A set of flags to control bank hardware save and restore operations. If the CriticalTransition flag bit is set, this idle state transition is being done as part of a critical transition in which the power engine plug-in (PEP) puts the system into a low-power state.
Remarks
The Parameters parameter of the CLIENT_SaveBankHardwareContext and CLIENT_RestoreBankHardwareContext event callback functions is a pointer to a caller-allocated GPIO_SAVE_RESTORE_BANK_HARDWARE_CONTEXT_PARAMETERS structure.
