STRUCT DRM_IVPU_CMDQ_CREATE(9)

✨ struct drm_ivpu_cmdq_create(9) ✨

Hey bestie, welcome to the Kernel API Manual 🫶 — this is the one where we learn about struct drm_ivpu_cmdq_create, aka the glow-up moment where a command queue gets born so jobs have somewhere to be submitted. Literally main character energy for the NPU. 💅

---

🌸 NAME 🌸

struct drm_ivpu_cmdq_create — create a command queue for job submission, periodt. 🎀

---

🦋 SYNOPSIS 🦋

struct drm_ivpu_cmdq_create {
    __u32 cmdq_id;
    __u32 priority;
    __u32 flags;
 };

That's the whole little guy. Three fields, no cap. 💖

👑 Members 👑

💫 cmdq_id

The returned ID of the created command queue. That's it, that's the field — it gets handed back to you so you know which queue you're dealing with. 🎯

💫 priority

The priority to be set for the related job command queue. It can be one of the following:

• DRM_IVPU_JOB_PRIORITY_DEFAULT
• DRM_IVPU_JOB_PRIORITY_IDLE
• DRM_IVPU_JOB_PRIORITY_NORMAL
• DRM_IVPU_JOB_PRIORITY_FOCUS
• DRM_IVPU_JOB_PRIORITY_REALTIME

Pick your fighter, bestie. 🌈

💫 flags

Supported flags:

🔥 DRM_IVPU_CMDQ_FLAG_TURBO

Enable low-latency mode for the command queue. The NPU will maximize performance when executing jobs from such a queue — at the cost of increased power usage. So yeah, it ate, but your battery is gonna feel it. 💀⚡

Later, bestie! This lil' page lives in ./include/uapi/drm and was dated October 2026 — and the header up top was struct drm_ivpu_cmdq_create(9), bestie, in case you forgot already. 💜🍓
