Add retry to slave core wakeup path

2019-01-25T16:07:27+00:00

We are still seeing some very intermittent errors in the slave core wakeup path. It still seems like we may have a timing issue. Until we figure out exactly what is going on, I am adding a retry mechanism that should get the core to report in correctly. The retry is done by issuing an additional doorbell message to the core that didn't report in.

Inband MMIO access to OCMB

2018-12-13T20:55:16+00:00

This is an untested version of the new MMIO device driver that will give access to the OCMB. It will be tested once the Axone model IPLs in Simics.

There was only support for non-recursive mutexes. This commit adds support for recursive mutexes and a new API for using them.

Fixes to node IPC messaging to handle non-zero base addresses

2018-06-07T17:37:46+00:00

Current code has each Node calculate each Remote Node's IPC area remote address by performing a fixed format calculation. This change has each Node calculating its IPC area Remote address and posting this value to a local SCOM register. A Node reads a Remote Node's SCOM register to acquire the Remote IPC area address.

Implement Interrupt Resource Provider Init for MPIPL Multi-Node Systems

2018-05-07T20:18:19+00:00

- 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 Change-Id: Idb742eafc7389f328ea7f506c4c4541c989e52b6 RTC: 182712 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/57993 Tested-by: Jenkins Server Tested-by: Jenkins OP Build CI Reviewed-by: Prachi Gupta Tested-by: Jenkins OP HW Reviewed-by: Christian R.
