MFC commands can be used to control the order in which DMA storage
accesses are performed.
The MFC synchronization commands are shown in
Table 3. There
are:
- four atomic commands (getllar, putllc, putlluc,
and putqlluc),
- three send-signal commands (sndsig, sndsigf,
and sndsigb),
- three barrier commands (barrier , mfcsync ,
and mfceieio ).
