ENUM DRM_XE_OBSERVATION_IOCTLS(9)

💅 NAME 💅

Okay bestie, welcome to the enum drm_xe_...ation_ioctls(9) page from the Kernel API Manual ✨ — this one is all about Observation stream fd ioctls. That’s the whole vibe. 🎀

✨ SYNOPSIS ✨

enum drm_xe_observation_ioctls {
    DRM_XE_OBSERVATION_IOCTL_ENABLE ,
    DRM_XE_OBSERVATION_IOCTL_DISABLE ,
    DRM_XE_OBSERVATION_IOCTL_CONFIG ,
    DRM_XE_OBSERVATION_IOCTL_STATUS ,
    DRM_XE_OBSERVATION_IOCTL_INFO

};

🎀 Constants 🎀

These are the constants in the enum, no cap:

• DRM_XE_OBSERVATION_IOCTL_ENABLE — enables data capture for an observation stream 🔥
• DRM_XE_OBSERVATION_IOCTL_DISABLE — disables data capture for an observation stream 💀
• DRM_XE_OBSERVATION_IOCTL_CONFIG — changes the observation stream configuration 🛠️
• DRM_XE_OBSERVATION_IOCTL_STATUS — returns observation stream status 👀
• DRM_XE_OBSERVATION_IOCTL_INFO — returns observation stream info 🫶

🌸 Description 🌸

The tea ☕: the information exchanged between userspace and kernel for observation fd ioctls is stream type specific. Like, it depends on the stream type — that’s the rule, bestie 💖
