STRUCT DM_COMPRESSOR_INFO(9)

✨ struct dm_compressor_info(9) ✨

okay so bestie, we're in the Kernel API Manual today and the main character is struct dm_compressor_info — it's the buffer info that frame buffer compression uses. yes, iconic, I know 💅

---

🎀 NAME 🎀

struct dm_compressor_info — the buffer info that frame buffer compression uses. that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

struct dm_compressor_info {
    void *cpu_addr;
    struct amdgpu_bo *bo_ptr;
    uint64_t gpu_addr;
 };

literally just three members, no cap. look at her go 🫶

---

💖 Members 💖

• cpu_addr — the MMIO cpu addr. that's the cpu-side address, periodt ✨
• bo_ptr — pointer to the buffer object 👑 (yes, the actual buffer object, she's pointing right at it)
• gpu_addr — the MMIO gpu addr. gpu-side address, bestie 🌸

🌈 SEE ALSO 🌈

highkey go read the kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h — that's where the whole friend group lives 🧚

like, the whole group chat is in there 💀

ngl there's nothing dangerous in here — she's just a little struct holding three fields. no warnings, no bugs, no exit codes, no environment variables. we stay safe and we stay slaying 😭💜

okay that's the page! 🍓 it's from ./drivers/gpu/drm/amd/display/..., dated October 2026, and it's literally titled struct dm_compressor_info(9) — mwah, go off, kernel docs 🔥👑
