💅 accel_open(9) — Kernel API Manual vibes ✨

Okay so bestie, this is the accel_open(9) page from the Kernel API Manual, and it’s lowkey iconic. Let’s get into it 🫶

🌸 NAME 🌸

  • accel_open — open method for ACCEL file

🎀 SYNOPSIS 🎀

int accel_open (struct inode *inode , struct file *filp );

🦋 ARGUMENTS 🦋

  • inode — device inode
  • filp — file pointer.

💅 DESCRIPTION 💅

This function must be used by drivers as their file_operations.open method. No cap.

It looks up the correct ACCEL device and instantiates all the per-file resources for it. It also calls the drm_driver.open driver callback. Slay, it’s doing the absolute most in the best way 💖

🔥 RETURN 🔥

0 on success or negative errno value on failure. That’s the whole vibe check ✨
