Struct InvalidationWaitDw0Dw1

pub struct InvalidationWaitDw0Dw1(/* private fields */);

Expand description

Invalidation Wait Descriptor (type 0x05, §6.5.2.8).

SW and IF independently request completion notifications; both may be disabled. FN controls following-descriptor ordering, not notification (§6.5.2.11). This implementation accepts SW=IF=FN=0 as a wait without notification or fence; §7.10 also gives an explicit fence-only example.

Bits [3:0]   = Type (0x05)
Bit  [4]     = IF (Interrupt Flag — generate invalidation completion event)
Bit  [5]     = SW (Status Write — write status data to status address)
Bit  [6]     = FN (Fence — complete this wait before following descriptors)
Bit  [7]     = PD (Page-request Drain)
Bit  [8]     = reserved
Bits [11:9]  = Type[6:4] (zero)
Bits [31:12] = reserved
Bits [63:32] = Status Data (32-bit value to write)
Bits [65:64] = reserved
Bits [127:66]= Status Address [63:2] (DWORD-aligned)
