GFXVTBAR Registers
8.24 Invalidation Event Data Register (IEDATA)—
Offset A4h
Register specifying the Invalidation Event interrupt message data.
This register is treated as RsvdZ by implementations reporting Queued Invalidation
(QI) as not supported in the Extended Capability register.
Access Method
Default: 0h
8.25 Invalidation Event Address Register (IEADDR)—
Offset A8h
Register specifying the Invalidation Event Interrupt message address.
This register is treated as RsvdZ by implementations reporting Queued Invalidation
(QI) as not supported in the Extended Capability register.
Access Method
Default: 0h
Type: MEM
(Size: 32 bits)
Offset: [B:0, D:0, F:0] + A4h
