STRUCT MSM_DISP_STATE(9)

📦 version 7.3.1, in nixpkgs unstable

👑 struct msm_disp_state(9) 👑

okay so bestie, we're in the Kernel API Manual today, and the star of the show is this little struct. it's called msm_disp_state and honestly? it's giving "i hold the entire dpu state so you don't have to" energy. coredump core memory fr fr 💖

🌸 NAME 🌸

struct msm_disp_state — the structure that stores the current dpu state. that's it, that's the whole vibe. it's the container, the moment, the whole scrapbook 📸

✨ SYNOPSIS ✨

struct msm_disp_state {
    struct device *dev;
    struct drm_device *drm_dev;
    struct list_head blocks;
    struct drm_atomic_commit *atomic_state;
    struct timespec64 time;
 };

look at her. five fields. no notes. slay 💅

🎀 MEMBERS 🎀

okay let's meet the cast, one by one, main character energy only:

  • dev — the device pointer 🫶 like, the device. the one we're talking about.
  • drm_dev — the drm device pointer 🌈 the drm-flavoured device, if you will. two devices, two pointers, no confusion.
  • blocks — list head for the hardware state blocks 🧱 it's a struct list_head, and it's holding together all those hardware state blocks like a group chat moderator.
  • atomic_state — the atomic state duplicated at the time of the error 😭 yes bestie, this is the frozen-in-amber copy of what things looked like right when it all went wrong. forensic queen.
  • time — the timestamp at which the coredump was captured ⏰ a struct timespec64, so you know exactly when the drama went down. receipts.

if you liked this struct (and you did), please direct your attention to the kernel file ./drivers/gpu/drm/msm/disp/msm_disp_snapshot.h and its absolutely iconic supporting cast 💜:

go read them. i'll wait. actually no i won't, i'll be right here 🍓

no cap, this whole thing lives under ./drivers/gpu/drm/msm/disp and the manual is dated October 2026 — mark your calendars bestie, that's the era this page is from ⭐

and that's the page! mwah, bye, go read your kernel source 💖🎀🦋✨
