STRUCT SMU_MSG_CTL(9)

💖 NAME 💖

okay so bestie, struct smu_msg_ctl(9) is a page from the Kernel API Manual, and it's literally the per-device message control block. ngl, it's giving main character energy as a standalone control block that encapsulates everything needed for SMU messaging. The way that ops->send_msg implements the complete protocol including all filtering and error handling? highkey iconic. no cap, that's the whole point. 💅✨

✨ SYNOPSIS ✨

struct smu_msg_ctl {
    struct smu_context *smu;

    struct smu_msg_config config;
    const struct smu_msg_ops *ops;
    const struct cmn2asic_msg_mapping *message_map;
    u32 default_timeout;
    u32 flags;
 };

not me noticing the original page just drops the Members heading and then dips — there are no per-member blurbs listed here, bestie. fr fr, the fields are all up in the synopsis above, slay. 💨
