STRUCT SCMI_RESET_PROTO_OPS(9)

💅 struct scmi_reset_proto_ops(9) — Kernel API Manual, but make it make sense

Okay so bestie, picture this: it's a struct in the Kernel API Manual (section 9, obviously), and its whole entire job is to hold the various operations provided by the SCMI Reset Protocol. Like, that's it. That's the vibe. It's a bundle of function pointers, and every single one of them gets handed a const struct scmi_protocol_handle *ph so it knows whose business it's minding. Iconic behavior, honestly.

✨ SYNOPSIS ✨

struct scmi_reset_proto_ops {
    int (*num_domains_get)(const struct scmi_protocol_handle *ph);
    const char *(*name_get)(const struct scmi_protocol_handle *ph, u32 domain);
    int (*latency_get)(const struct scmi_protocol_handle *ph, u32 domain);
    int (*reset)(const struct scmi_protocol_handle *ph, u32 domain);
    int (*assert)(const struct scmi_protocol_handle *ph, u32 domain);
    int (*deassert)(const struct scmi_protocol_handle *ph, u32 domain);
 };

🎀 Members (the whole squad, one by one)

• num_domains_get — grab the count of reset domains that SCMI is serving up. Like a headcount before the party. 🎉
• name_get — gets the name of a reset domain. Yes bestie, they have names, they're not just numbers. 💖
• latency_get — gets the reset latency for the specified reset domain. So you know exactly how long the dramatic pause lasts. ⏳
• reset — resets the specified reset domain. Boom. Clean slate. 🔥
• assert — explicitly assert the reset signal of the specified reset domain. Not implied, not vibes-based — explicitly. 💅
• deassert — explicitly deassert the reset signal of the specified reset domain. The opposite of the above, and equally explicit. 🦋
