STRUCT GUC_MMIO_REG_SET(9)

🌸 struct guc_mmio_reg_set(9) 🌸

okay bestie, welcome to the Kernel API Manual entry for struct guc_mmio_reg_set — yes we're reading kernel ABI docs together, this is our hangout now 💖

---

✨ NAME ✨

struct guc_mmio_reg_set — GuC register sets. that's it, that's the name, short and iconic 👑

---

🎀 SYNOPSIS 🎀

struct guc_mmio_reg_set {
    u32 address;
    u16 count;
    u16 reserved;
 };

like look at her. three fields. compact. efficient. main character energy fr fr 💅

🦋 Members 🦋

• address — the register address. it's a u32, it's where the thing lives, periodt 📍
• count — the register count. a u16, telling you how many registers we're talking about 🔢
• reserved — reserved. it's a u16 and it is, respectfully, just sitting there holding space for the future 🙈 don't touch it, don't read into it, it's reserved 💀

🌈 Description 🌈

GuC register sets. that's the whole description ngl — sometimes the manpage just says the thing and we respect that 🫶

lowkey this is a "trust the header file" situation. the real lore lives in ./drivers/gpu/drm/xe/abi/guc_capture_abi.h and the SEE ALSO squad below 👇
