ENUM DRM_GPU_SCHED_STAT(9)

💅 enum drm_gpu_sched_stat(9)

okay so bestie, welcome to the Kernel API Manual page for enum drm_gpu_sched_stat(9) — yes the whole name, we're being formal today ✨ this is literally the scheduler's status enum and she's kind of a big deal in DRM land 🎀

---

🌸 NAME 🌸

enum drm_gpu_sched_stat — the scheduler's status 💫 like, the vibe check for your GPU scheduler, fr fr

---

✨ SYNOPSIS ✨

enum drm_gpu_sched_stat {
    DRM_GPU_SCHED_STAT_NONE ,
    DRM_GPU_SCHED_STAT_RESET ,
    DRM_GPU_SCHED_STAT_ENODEV ,
    DRM_GPU_SCHED_STAT_NO_HANG

};

that's the whole lineup, four little constants, no cap 🫶

---

🦋 Constants 🦋

so these are the members, and each one has lore:

• DRM_GPU_SCHED_STAT_NONE — Reserved. Do not use. that's it, that's the message, she's reserved, hands off, periodt 🙈
• DRM_GPU_SCHED_STAT_RESET — the GPU hung and then successfully reset 🔥 like it fainted and then came back slay 💅
• DRM_GPU_SCHED_STAT_ENODEV — Error: Device is not available anymore. yeah the device is gone gone 😭 not me checking for a device that literally does not exist
• DRM_GPU_SCHED_STAT_NO_HANG — plot twist 👑 contrary to the scheduler's assumption, the GPU did not hang and is still running. the scheduler assumed wrong and honestly? iconic 💀
