include: mailbox: Update RPMI notification structs and add performance events

2026-06-10T12:43:10Z

Add rpmi_event_notification_state enum with disable, enable, and return current state IDs. Also, add req_state field to rpmi_enable_notification_req and current_state field to rpmi_enable_notification_resp for RPMI specification compliance. Add notification event ID enum and data structures for RPMI Performance service group events: power change, limit change, and level change. Signed-off-by: David E.

include: mailbox: rpmi_msgprot: Add RPMI performance domain flag defines

2026-06-07T11:16:56Z

Add bit-field defines for the RPMI performance domain attributes flags and fast-channel attributes flags as specified in the RPMI specification. These are needed by platform implementations that provide RPMI performance services (e.g. DVFS controllers). Also add the missing db_write_value field to rpmi_perf_get_fast_chn_attr_resp to match the RPMI spec layout. Signed-off-by: David E.

lib: utils/mailbox: Parse P2A doorbell system MSI index from DT

2025-05-20T05:40:35Z

The P2A doorbell system MSI index is expected to be discovered from device tree instead of RPMI system MSI service group attribute. This is based on ARC feedback before RPMI spec was frozen. Let's parse P2A doorbell system MSI index from device tree and also expose it as rpmi channel attribute to RPMI client drivers.
