PEP_ACPI_GPIO_RESOURCE structure (pep_x.h)

  • Article

The PEP_ACPI_GPIO_RESOURCE structure describes the ACPI configuration for a general purpose input/output (GPIO) resource.

Syntax

typedef struct _PEP_ACPI_GPIO_RESOURCE {
  PEP_ACPI_RESOURCE_TYPE      Type;
  PEP_ACPI_RESOURCE_FLAGS     Flags;
  KINTERRUPT_MODE             InterruptType;
  KINTERRUPT_POLARITY         InterruptPolarity;
  GPIO_PIN_CONFIG_TYPE        PinConfig;
  GPIO_PIN_IORESTRICTION_TYPE IoRestrictionType;
  USHORT                      DriveStrength;
  USHORT                      DebounceTimeout;
  PUSHORT                     PinTable;
  USHORT                      PinCount;
  UCHAR                       ResourceSourceIndex;

} PEP_ACPI_GPIO_RESOURCE, *PPEP_ACPI_GPIO_RESOURCE;

Members

Type

A PEP_ACPI_RESOURCE_TYPE enumeration value that identifies the resource type for this ACPI resource.

Flags

A PEP_ACPI_RESOURCE_FLAGS structure that describes the capabilities of this ACPI resource.

InterruptType

A KINTERRUPT_MODE enumeration value that identifies the interrupt type.

InterruptPolarity

A KINTERRUPT_POLARITY enumeration value that identifies how a device signals an interrupt request on an interrupt line.

PinConfig

A GPIO_PIN_CONFIG_TYPE enumeration value that identifies the GPIO pin configuration type.

IoRestrictionType

A GPIO_PIN_IORESTRICTION_TYPE enumeration value that identifies the type of IO that the pin supports.

DriveStrength

Specifies the output drive capability of the pin, in hundredths of milliamperes.

DebounceTimeout

Specifies the hardware debounce wait time, in hundredths of milliseconds.

PinTable

A list of pin numbers on the resource that are described by this descriptor.

PinCount

The number of pins in PinTable.

ResourceSourceIndex

This member is always zero.

ResourceSourceName

This member is always set to "ResourceConsumer."

VendorData

A pointer to a raw data buffer containing vendor-defined byte data to be decoded by the OS driver.

VendorDataLength

The size of the VendorData buffer.

Requirements
