STRUCT DRM_IOCTL_DESC(9)

💅 struct drm_ioctl_desc(9) 💅

✨ NAME ✨

struct drm_ioctl_desc — DRM driver ioctl entry. Okay so this is the Kernel API Manual page for it, bestie, and it’s literally the little struct that describes one DRM driver ioctl entry 💖

🎀 SYNOPSIS 🎀

struct drm_ioctl_desc {
    unsigned int cmd;
    enum drm_ioctl_flags flags;
    drm_ioctl_t *func;
    const char *name;
 };

🦋 Members 🦋

• cmd — the ioctl command number, without flags. No cap, that’s the whole vibe ✨
• flags — a bitmask of enum drm_ioctl_flags 🎯
• func — the handler for this ioctl 👑
• name — a user-readable name for debug output, so debugging can actually slay 🔥

🌸 Description 🌸

For convenience it’s easier to create these using the DRM_IOCTL_DEF_DRV macro. That’s it, that’s the note — iconic little shortcut behavior, fr fr 🫶
