1576 | SMTC pseudo-interrupts between TCs are deferred and queued | ||
1577 | if the target TC is interrupt-inhibited (IXMT). In the first | ||
1578 | SMTC prototypes, these queued IPIs were serviced on return | ||
1579 | to user mode, or on entry into the kernel idle loop. The | ||
1580 | INSTANT_REPLAY option dispatches them as part of local_irq_restore() | ||
1581 | processing, which adds runtime overhead (hence the option to turn | ||
1582 | it off), but ensures that IPIs are handled promptly even under | ||
1583 | heavy I/O interrupt load. | ||
