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 10-578, RINGACC Ring Mapping)
- 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 in
Module Integration 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)
