Implement Interrupt Resource Provider Init for MPIPL Multi-Node Systems
- In MPIPL the HW interrupt config could be such that interrupts will
cross node boundaries. HB handles interrupts independently on each
node - so initialize INTRP in a way to handle this transition.
- Modify the MPIPL flow with the following changes:
a) Set the Interrupt LSI State Machine to disabled
b) Enable LSI Mode via the Interrupt Control Register
c) Force all nodes to sync after steps a + b
- Enable INTRP Multi-Node MPIPL Sync Code developed in P8
- Each node will now initialize its own internode_info
data area during an initial IPL
- Coalescing of the Host will modify this data to define
all the nodes in the system
- During the MPIPL each node can view each others area to
determine when all nodes have reached the common sync point
- Remove Legacy P8 MPIPL INTRP Code that is not used
