STRUCT DMUB_SRV_CREATE_PARAMS(9)

🎀 struct dmub_srv_create_params — NAME 🎀

Okay so bestie, welcome to the Kernel API Manual page for struct dmub_srv_create_params 💅 — literally the struct you fill out when you want to create a DMUB service. It's the little info packet of params for dmub service creation, and it ate. ✨

🌸 SYNOPSIS 🌸

This is the whole vibe, copy it exactly, no cap:

struct dmub_srv_create_params {
    struct dmub_srv_base_funcs funcs;
    struct dmub_srv_hw_funcs *hw_funcs;
    void *user_ctx;
    enum dmub_asic asic;
    uint32_t fw_version;
    bool is_virtual;
    enum dmub_inbox_cmd_interface_type inbox_type;
 };

💖 Members 💖

Alright so here's the member-by-member breakdown, and honestly? Each one is doing its own little job 🫶

• hw_funcs — optional overrides for the hw funcs. Optional!! She doesn't have to show up, but if she does, she's overriding. 👑
• user_ctx — the context data for the callback funcs. It's giving "your stuff, passed back to you." 🎀
• asic — the driver supplied asic. The driver brought it, we're just holding it. 💅
• fw_version — the current firmware version, if any. Note the "if any" — sometimes there just isn't one and that's fine. 🌸
• is_virtual — false for hw support only. Like, hw support and nothing else, periodt. ⭐
