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

To support multiple TC microthreads acting as "CPUs" within
a VPE, VPE-wide interrupt mask bits must be specially manipulated
during interrupt handling. To support legacy drivers and interrupt
controller management code, SMTC has a "backstop" to track and
if necessary restore the interrupt mask. This has some performance
- impact on interrupt service overhead. Disable it only if you know
