MSI
Message signaled Interrupt
MSI-X
Message signaled interrupt extension
One of two PCI-defined extensions to
support message signaled interrupts
(MSI), in PCI 2.2 and later and PCI
Express. MSIs are an alternative way of
generating an interrupt through special
messages that allow emulation of a pin
assertion or deassertion.
MSI-X (defined in PCI 3.0) allows a device
to allocate any number of interrupts
between 1 and 2048 and gives each inter-
rupt separate data and address registers.
Optional features in MSI (64-bit
addressing and interrupt masking) are
mandatory with MSI-X.
