i915_ioc32_compat_ioctl — handle the mistakes of the past ✨

✨ SYNOPSIS ✨

long i915_ioc32_compat_ioctl (struct file *filp , unsigned int cmd ,
       unsigned long arg );

🎀 ARGUMENTS 🎀

• filp — the file pointer. literally the file pointer, bestie. 📁
• cmd — the ioctl command (and encoded flags). so it’s the command, and yes, the encoded flags are in there too. 🎛️
• arg — the ioctl argument (from userspace). straight from userspace, no cap. 🫶

🦋 DESCRIPTION 🦋

okay so here’s the vibe: this function is called whenever a 32-bit process running under a 64-bit kernel performs an ioctl on /dev/dri/card<n>.

that’s it, that’s the whole description. it’s giving “small function, very specific job” and honestly? iconic. 💅
