STRUCT DRM_ROCKET_TASK(9)

💜 NAME 💜

struct drm_rocket_task — the little baby unit of work that gets run on the NPU, bestie ✨

Okay so before we even get into it, this header situation: this page lives in the Kernel API Manual, and it's all about struct drm_rocket_task. That's the vibe. Sit with it 🫶

---

🌸 SYNOPSIS 🌸

struct drm_rocket_task {
    __u32 regcmd;
    __u32 regcmd_count;
};

That's the whole struct, ngl. Two __u32s. Tiny. Iconic. Absolutely carrying the NPU on its back 💅

---

🎀 Members 🎀

• regcmd — Input, bestie: a DMA address to the NPU mapping of the register command buffer. So like… it's not the buffer itself, it's where the buffer lives as far as the NPU is concerned. Location check, slay ✨
• regcmd_count — Input again: the number of commands chilling inside that register command buffer. Like how many things you're about to do. Counting matters 🧮💖

---

🦋 Description 🦋

A task is the smallest unit of work that can be run on the NPU. That's it. That's the whole personality. Smallest. Unit. Of work. Main character energy but make it micro 👑🌱

Everything else gets built on top of this little guy. Respect the little guy fr fr 😤💜
