pvr_drm_driver_open(9)

💖 NAME 💖

okay so bestie, this is the pvr_drm_driver_open(9) page from the Kernel API Manual — and the whole vibe is: pvr_drm_driver_open is the driver callback for when a new &struct drm_file is opened. It's literally the "new file just dropped" moment. 💅

✨ SYNOPSIS ✨

int pvr_drm_driver_open (struct drm_device *drm_dev , struct drm_file
       *file );

That's the signature, no edits, no cap.

🎀 ARGUMENTS 🎀

• drm_dev — [IN] DRM device. The device in question, marked input.
• file — [IN] DRM file private data. The per-file private-data situation, marked input.

💅 DESCRIPTION 💅

This callback allocates the powervr-specific file private data — literally a struct pvr_file, periodt. It's registered in pvr_drm_driver, so that's where it gets hooked in. 🫶

🌈 RETURN 🌈

• 0 on success — iconic.
• -ENOMEM if the allocation of a struct ipvr_file fails — yes bestie, the return section says struct ipvr_file; keep your eyes on the exact name. 😭
• Any error returned by pvr_memory_context_init — whatever that error is, it comes through.
