From 59fe435b2840da294fa054012ac23e26a8f325c0 Mon Sep 17 00:00:00 2001 From: "David E. Garcia Porras" Date: Mon, 8 Jun 2026 18:22:55 +0530 Subject: [PATCH] include: mailbox: Update RPMI notification structs and add performance events 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.
