pseries_eeh_write_config(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual page for pseries_eeh_write_config(9) — yes, that's the manual name, folded in right here instead of doing a boring header copy. The function is literally called pseries_eeh_write_config, and it does one iconic thing: write PCI config space. Periodt. 💅

✨ SYNOPSIS ✨

int pseries_eeh_write_config (struct eeh_dev *edev , int where , int
size , u32 val );

🎀 ARGUMENTS 🎀

• edev — EEH device handle. It's giving "your device's backstage pass" 🫶
• where — PCI config space offset. Basically where in config space we're writing.
• size — size to write. Yep, the size — not the vibe check.
• val — value to be written. The actual value going in. Slay.

🦋 DESCRIPTION 🦋

Write config space to the specified device. That's the whole mood, no cap. ✨
