STRUCT SCMI_EVENT_OPS(9)

💅 struct scmi_event_ops(9)

okay so this is from the Kernel API Manual bestie, and it's literally the struct scmi_event_ops page — aka the protocol helpers that the notification core calls up when it needs something. no cap, this is the group chat between SCMI protocols and the notify core 🫶

---

✨ NAME ✨

struct scmi_event_ops — the protocol helper crew that the notification core rings up whenever it needs a favor. literally their whole job 💖

---

🌸 SYNOPSIS 🌸

struct scmi_event_ops {
    bool (*is_notify_supported)(const struct scmi_protocol_handle *ph,
u8 evt_id, u32 src_id);
    int (*get_num_sources)(const struct scmi_protocol_handle *ph);
    int (*set_notify_enabled)(const struct scmi_protocol_handle *ph, u8
evt_id, u32 src_id, bool enabled);
    void *(*fill_custom_report)(const struct scmi_protocol_handle *ph,
u8 evt_id, ktime_t timestamp, const void *payld, size_t payld_sz, void
*report, u32 *src_id);
 };

like, that's the whole squad right there 👑 four function pointers, all main character energy.

🎀 Members 🎀

• is_notify_supported — returns 0 if the notification you asked about for that specific resource (src_id) is supported. short king, one job, does it well ✨
• get_num_sources — hands back the number of possible event sources for this protocol. it's giving census-taker energy 🦋
• set_notify_enabled — turns the required evt_id/src_id notifications on or off, using the proper custom protocol commands (no shortcuts bestie, do it the right way). returns 0 on Success 💅
• fill_custom_report — fills in a custom event report from the event message payld you handed it, identifying the event-specific src_id. returns NULL on failure, otherwise the report comes back fully populated and slayed 🌈

💜 Context 💜

the helpers described in struct scmi_event_ops are called only in process context. that's the vibe check — no weird contexts allowed 🧚

go read those two structs next fr fr, they're the friends of this one 😭

okay that's the whole page bestie, hope it ate 💖 this came out of ./drivers/firmware/arm_scmi, dated October 2026, and it's titled struct scmi_event_ops(9) — periodt 🎀
