ENUM STP_PACKET_TYPE(9)

💖 NAME 💖

enum stp_packet_type — bestie, this is literally the enum of STP packets that an STM driver sends 👑

So we're in the Kernel API Manual, and this is the whole vibe: one little enum, seven constants, and honestly not a single description to its name 😭 iykyk.

✨ SYNOPSIS ✨

enum stp_packet_type {
    STP_PACKET_DATA ,
    STP_PACKET_FLAG ,
    STP_PACKET_USER ,
    STP_PACKET_MERR ,
    STP_PACKET_GERR ,
    STP_PACKET_TRIG ,
    STP_PACKET_XSYNC

};

That's the whole cast 🫶 all seven members, in order, no gatekeeping.

🎀 Constants 🎀

Okay so here's the thing, and I need you to not be mad at me: the source page gives every single one of these as -- undescribed -- 💀 That's not me skipping the tea, that's literally what the doc says. Every. Single. One.

• STP_PACKET_DATA — -- undescribed -- 🙈
• STP_PACKET_FLAG — -- undescribed -- 🙈
• STP_PACKET_USER — -- undescribed -- 🙈
• STP_PACKET_MERR — -- undescribed -- 🙈
• STP_PACKET_GERR — -- undescribed -- 🙈
• STP_PACKET_TRIG — -- undescribed -- 🙈
• STP_PACKET_XSYNC — -- undescribed -- 🙈

ngl the mystery is kind of iconic, but fr fr if you need the real meaning, go read the source. The manpage is giving "leave them wanting more" 💅

And that's the post 💜 this beauty lives in ./include/linux, dated October 2026 — so it's basically from the future, main character energy only 💫 slay, bye! 🎀✨
