Multi-Drawer (IPC) Interrupt/Messaging Support

2018-01-25T22:44:20+00:00

- 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.

Avoid deadlock in cross-node IPC messaging

2015-06-08T18:30:31+00:00

Move poll for empty queue out of kernel space to allow for the primary thread to see new interrupts and clear out incoming messages. This will prevent 2 nodes from deadlocking one another while they wait for each other to handle the last message that was sent to them.

ERRL: Create Hostboot error log SRC/UD parser and deliver to FSP bld

2013-02-08T22:49:45+00:00

A new script called genErrlParsers will scan the Hostboot code for error log tags and create a SRC parser for each component. The script will also scan the Hostboot code for plugin directories containing User Detail Data parsers and will create a makefile that is used by the FSP to build each component's SRC/UD parser.
