This section describes the interrupt-related information that flows within DMSS and how this information is configured or generated.
- Ring Number (R#)
- Data is read from and written to a specific Ring
Accelerator ring using direct ring-mode, or secure
proxy access
- The Ring Accelerator has specific ring number
ranges for specific purposes. The R# must match
the intended purpose of the ring. see Table 11-66 for details.
- Global Event and Event Numbers (GE# and E#)
- GE# = EO + E#
- EO determines the destination module for the
event. The PSILSS will route the GE# to the
destination module per the DMSS event mapping,
removing EO in the process. The destination module
sees only E#. See Global Event Map for details.
- For the INTAGGR module, E# ranges from 0 to
(IA_SEVI - 1)
- Virtual Interrupt (VI#)
- The INTAGGR maps E# (via software configuration)
to any SB#
- ranges from 0 to (IA_SEVI - 1)
- Each VI# (0 – (IA_VINTR-1)) is driven by a group
of 64 contiguous SB# numbers (VI# driven by SB#'s
VI#×64 – (VI#×64)+63)
