int xe_eu_stall_stream_open (struct drm_device *dev , u64 data , struct drm_file *file );

💖 ARGUMENTS 💖

• dev — DRM device pointer, aka the whole device vibe check 👑
• data — pointer to the first struct drm_xe_ext_set_property in the chain of input properties coming at us from user space 🫶 (yes, first — it's a whole chain, not just one lonely struct)
• file — DRM file pointer, the file in question fr fr 💅

🌈 DESCRIPTION 🌈

This function opens a EU stall data stream with input properties from the user space. That's it, that's the whole thing — but like, it's iconic 💀✨
