Multi-Drawer (IPC) Interrupt/Messaging Support
- 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.
