STRUCT PCI_HOST_PERST(9)

💅 NAME

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for struct pci_host_perst(9) — and it’s literally the PERST# GPIO descriptor 🎀

✨ SYNOPSIS

here’s the whole struct, no cap:

       struct pci_host_perst {
           struct list_head        list;
           struct gpio_desc        *desc;
        };

🎀 Members

• list — the list node used for linking multiple PERST# GPIOs 🫶
• desc — the GPIO descriptor for the PERST# signal ⭐

🦋 Description

This structure holds a single PERST# GPIO descriptor 💖 it’s giving small-but-iconic, and that’s the whole vibe 😌
