DWPCIE(4)

💅 DWPCIE(4) — the Synopsys DesignWare Host/PCIe bridge, bestie edition 🎀

okay so real talk, this is a page from the Kernel Interfaces Manual, section 4, and it's about dwpcie — say it with me, it's giving "DesignWare PCIe" and it's lowkey iconic. 🦋

✨ SYNOPSIS ✨

dwpcie* at fdt?
pci* at dwpcie?

like, that's it. that's the whole vibe. dwpcie* attaches at fdt?, and then pci* attaches at dwpcie?. nesting dolls but make it kernel. 💅

🌸 DESCRIPTION 🌸

so the dwpcie driver is literally out here providing support for the Synopsys DesignWare PCIe controller — no cap, that's the whole job. and where does this controller live? it's built into various SoCs. not bolted on, not hot-glued, built in. main character energy fr fr. 👑
