PEP_ACPI_SPB_RESOURCE structure (pepfx.h)

  • Article

The PEP_ACPI_SPB_RESOURCE structure describes an ACPI serial bus connection resource.

Syntax

typedef struct _PEP_ACPI_SPB_RESOURCE {
  PEP_ACPI_RESOURCE_TYPE  Type;
  PEP_ACPI_RESOURCE_FLAGS Flags;
  USHORT                  TypeSpecificFlags;
  UCHAR                   ResourceSourceIndex;
  PUNICODE_STRING         ResourceSourceName;
  PCHAR                   VendorData;
  USHORT                  VendorDataLength;
} PEP_ACPI_SPB_RESOURCE, *PPEP_ACPI_SPB_RESOURCE;

Members

Type

A PEP_ACPI_RESOURCE_TYPE enumeration value describing this resource.

Flags

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

TypeSpecificFlags

Specifies the bit flags that are common to all serial bus connection types.

Bit(s) Meaning
0 - Subordinate mode
 0x0 - Indicates that communication over this connection is initiated by the controller.

0x1 - Indicates that communication over this connection is initiated by the device.
1 - Consumer/producer mode
 0x0 - Indicates that this device produces and consumes this resource.

0x1 - Indicates that this device consumes this resource.
2 to 7 - Reserved
 These bits are reserved and must be set to zero.

ResourceSourceIndex

ResourceSourceName

The name of the serial bus controller device to which this connection descriptor applies. The name can be a fully qualified path, a relative path, or a simple name segment that utilizes the namespace search rules.

VendorData

A pointer to optional data that is specific to the serial bus connection type.

VendorDataLength

The length of the buffer pointed to by VendorData.
