STRUCT HECI_GSC_DEF(9)

✨ struct heci_gsc_def(9) ✨

okay so this is a page straight outta the Kernel API Manual, and it's literally all about struct heci_gsc_def — the graphics security controller heci interface definitions 🎀 yes bestie, that's a whole mouthful, but stay with me, it's actually so cute and simple.

---

💖 NAME 💖

struct heci_gsc_def — graphics security controller heci interface definitions. that's the whole vibe. no cap.

---

🌸 SYNOPSIS 🌸

here's the whole struct, bestie, looking all iconic:

struct heci_gsc_def {
    const char *name;
    unsigned long bar;
    size_t bar_size;
    bool use_polling;
    bool slow_firmware;
 };

five little members, all doing their thing. slay.

🦋 Members 🦋

let me introduce you to the cast, one by one 👑

• name — the name of the heci device. that's it, that's the whole flex. it's a const char *, so it's just chillin' as a string 🫶
• bar — the address of the mmio bar. it's an unsigned long, so it's holding that address down 💅
• bar_size — the size of the mmio bar. a size_t, obviously, because we are not messy here ✨
• use_polling — the indication of using polling mode for the device. it's a bool, so it's giving yes/no energy 🎀
• slow_firmware — the indication of whether the device is slow (needs longer timeouts). also a bool. some devices just need a lil extra time, and that's valid 😭💖

ngl bestie, if you're poking at the GSC heci stuff, this struct is your main character. five fields, zero drama. periodt 💜

and that's the tea, bestie 🍓 — this lil page lives in ./drivers/gpu/drm/xe, dated October 2026, and it's your friendly neighbourhood struct heci_gsc_def(9) from the Kernel API Manual. mwah 💋✨
