okay so this is bcmpcie(4), straight outta the Kernel Interfaces Manual — the page for the Broadcom BCM2711 Host/PCIe bridge. It’s short, it’s specific, and it’s lowkey essential if you’re kicking it with the right hardware. 🫶

it’s giving “small page, very specific hardware, absolutely iconic” energy. 🍓
