STRUCT DRM_ETHOSU_JOB(9)

✨ struct drm_ethosu_job(9) ✨

okay so this is a page from the Kernel API Manual (yes, the manual name is literally "Kernel API Manual", we love that for us) and it's all about struct drm_ethosu_job 💅

---

🎀 NAME 🎀

struct drm_ethosu_job — a job to be run on the NPU. that's it, that's the whole vibe 🧚

---

🌸 SYNOPSIS 🌸

bestie here's the struct, copied exactly, no cap:

struct drm_ethosu_job {
    __u32 cmd_bo;
    __u32 sram_size;
  #define ETHOSU_MAX_REGIONS      8;
    __u32 region_bo_handles[ETHOSU_MAX_REGIONS];
 };

like look at her. cmd_bo? sram_size? region_bo_handles[ETHOSU_MAX_REGIONS]? and the #define ETHOSU_MAX_REGIONS 8; is just sitting there in the middle of the struct being iconic 👑

🦋 Members 🦋

so the original page has a Members section and then… literally nothing under it 😭 no cap, it's empty. the fields are all up in SYNOPSIS, go look there bestie 🫶

---

💖 Description 💖

okay so the real tea: the kernel will schedule the execution of this job, and it takes into account its dependencies with other jobs 🔥 (dependencies, the way that they matter).

and here's the slay part — all tasks in the same job will be executed sequentially on the same core, so they get to benefit from memory residency in SRAM 💜 like they're all hanging out in the same spot, main character energy, no bouncing around.
