* Only unmask source on proc targ passed to unmask function in intrrpChristian Geddes2018-08-011-20/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | There was a bug in the code where if an interrupt was resolved for a source the code to clean up the pending interrupt in the intrrp will unmask the source. This was actually unmasking the source on all processors. This causes odd behavior if there was an outstanding int on that source on one of the other processors. Essentially the intrrp would think that a new interrupt came in but we will already be handling it. The logic breaks down here and we end up getting in a locked state. Fixing this caused issues with Hostboot management of the maskList which kept track of which sources were masked. Instead of managing this list of masked sources hostboot will instead keep track of sources which are not registered to any msg Qs. When new processors are added to the interrupt resource provider after fabric is up, all LSI sources who are not registered to a msg Q will be masked for the new processor.

* Print out MBOX/INTR state info on DMA request hangChristian Geddes2018-07-051-0/+1
| | | | | | | | | | | | | | | | | | | | We have been stuck on a hang that occurs during memdiags on our multi-node p9 systems. It appears that Hostboot is never receiving the response to the request to reclaim DMA buffers from the FSP. From debugging we know the FSP thinks it has sent the message over the FSI mbox but hostboot isnt seeing it. Next time this happens if this is in the code we should be able to get a better idea of what is happening.

| | | | | | | | | | | | | | | | | | | | | | | | | | - Use doorbells instead of IPIs (no IPI support using LSI interupts in the XIVE intr architecture) - New message type from kernel to userspace so the kernel can notify the HB userspace Interrupt Resource Provider (INTRP) that an IPC message was sent to the particular HB instance (in P8 this happened automatically as that was part of the IPI architecture). - Re-enable testcase that validates that an IPC message can be successfully sent.

* Interrupt Handling Flow Change to Prevent DeadlockBill Hoffa2018-01-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | - Previously the End of Interrupt (EOI) message was sent after the registered interrupt handler completed handling of the defect. Instead of this, now the INTRP will immediately mask the current interrupt source and issue the HW EOI to allow other interrupt sources to present. - Later when the registered interrupt handler sends INTRP its EOI message the INTRP will unmask the source and issue the necessary HW EOI to fully clear the interrupt Change-Id: I01c99ca9fdd0cedcf3d313127a8d56f5cda66bc7 CQ: SW413511 Reviewed-on: http://ralgit01.raleigh.ibm.com/gerrit1/51691 Tested-by: Jenkins Server <pfd-jenkins+hostboot@us.ibm.com> Tested-by: Jenkins OP Build CI <op-jenkins+hostboot@us.ibm.com> Tested-by: Jenkins OP HW <op-hw-jenkins+hostboot@us.ibm.com> Reviewed-by: Daniel M.
