Expand description

The Generic Address Structure (GAS) provides the platform with a robust means to describe register locations.

Fields§

§address_space_id: u8

The address space where the data structure or register exists. Defined values are:

  • 0x00 - System Memory space
  • 0x01 - System I/O space
  • 0x02 - PCI Configuration space
  • 0x03 - Embedded Controller
  • 0x04 - SMBus
  • 0x05 - SystemCMOS
  • 0x06 - PciBarTarget
  • 0x07 - IPMI
  • 0x08 - General PurposeIO
  • 0x09 - GenericSerialBus
  • 0x0A - Platform Communications Channel (PCC)
  • 0x0B - Platform Runtime Mechanism (PRM)
  • 0x0C to 0x7E - Reserved
  • 0x7F - Functional Fixed Hardware
  • 0x80 to 0xFF - OEM Defined
§reg_bit_width: u8

The size in bits of the given register. When addressing a data structure, this field must be zero.

§reg_bit_offset: u8

The bit offset of the given register at the given address. When addressing a data structure, this field must be zero.

§access_size: u8

Specifies access size. Unless otherwise defined by the Address Space ID:

  • 0 - Undefined (legacy reasons)
  • 1 - Byte access
  • 2 - Word access
  • 3 - Dword access
  • 4 - QWord access
§address: u64

The 64-bit address of the data structure or register in the given address space (relative to the processor).
