ENUM DRM_ASAHI_IOCTL_ID(9)

💅 enum drm_asahi_ioctl_id(9)

okay bestie, welcome to the Kernel API Manual ✨ this one's a little enum called enum drm_asahi_ioctl_id, and honestly? it's giving "the master list of every ioctl the asahi driver fw knows about" 🎀

---

🌸 NAME 🌸

enum drm_asahi_ioctl_id — IOCTL IDs 💖 like, the whole cast list of ioctl numbers, no cap.

🦋 Constants 🦋

okay so here's the whole lineup, one by one, and yes we're going through all of them 🌈

• DRM_ASAHI_GET_PARAMS — queries the device properties. it's giving "hi what can u do" 💫
• DRM_ASAHI_GET_TIME — queries the device time. literally just clock-checking ⏰
• DRM_ASAHI_VM_CREATE — creates a GPU VM address space. new address space, new me 🎀
• DRM_ASAHI_VM_DESTROY — destroys a VM. rip to that address space, she served 🫶
• DRM_ASAHI_VM_BIND — binds/unbinds memory to a VM. attaching and detaching, the classic situationship 💀
• DRM_ASAHI_GEM_CREATE — creates a buffer object. tiny baby buffer, iconic 👑
• DRM_ASAHI_GEM_MMAP_OFFSET — gets the offset you pass to mmap to map a given GEM handle. yes bestie, mmap specifically 🧚
• DRM_ASAHI_GEM_BIND_OBJECT — binds memory as a special object. special object gets special treatment, periodt ⭐
• DRM_ASAHI_QUEUE_CREATE — creates a scheduling queue. get in line, literally 🌸
• DRM_ASAHI_QUEUE_DESTROY — destroys a scheduling queue. line's closed, bestie 🙈
• DRM_ASAHI_SUBMIT — submits commands to a queue. sending it, fr fr 🔥

💜 Description 💜

okay this is the important part so listen up ✋

Place new ioctls at the end, don't re-order, don't replace or remove entries. like, the order is sacred, do not touch it, do not be cute with it — new stuff goes at the end, always 💅

these IDs are not meant to be used directly. use the DRM_IOCTL_ASAHI_xxx definitions instead. iykyk 🫶
