STRUCT MSM_DISP_STATE_BLOCK(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct msm_disp_state_block(9)

okay bestie, welcome to the Kernel API Manual entry for struct msm_disp_state_block — and yes, this is the whole entire personality of this page: it's a little struct that holds onto one hardware block's state. that's it. that's the vibe. 🎀

✨ NAME ✨

struct msm_disp_state_block — the structure that stores each hardware block's state 💾✨ like it's literally the group chat's screenshot folder but for registers.

🦋 SYNOPSIS 🦋

here's the whole thing, no edits, no cuts, i would never:

struct msm_disp_state_block {
    char name[SZ_128];
    struct list_head node;
    unsigned int size;
    u32 *state;
    void __iomem *base_addr;
 };

that's the struct. five members. iconic. no cap. 🔥

🌸 Members 🌸

okay so let's meet the members one by one, they're all main characters in their own way 🫶

  • name — the name of the block. literally just the block's name bestie, so you know who's who 💅
  • node — the handle to the linked list head. it's how this block stays connected to the rest of the list, like it's holding hands with the group 🎀
  • size — the size of the register space of this hardware block. so how much register room this block gets to take up 📏✨
  • state — the array holding the register dump of this hardware block. this is the actual tea ☕ — the dumped registers live right here.
  • base_addr — the starting address of this hardware block's register space. the origin point, the home base, the "you are here" pin on the map 📍💜
ngl there are no options and no exit codes on this page — it's a struct, not a command. no flags to remember, we love a low-effort queen 👑
