DWXE(4)

💖 DWXE(4) — the Allwinner EMAC ethernet girlies 💖

okay so bestie, this is the manual page for dwxe, a 4-section kernel interfaces page, and it's literally all about the Allwinner EMAC 10/100/1Gb Ethernet device. yes that's a lot of numbers, no I will not apologise, let's get into it ✨

🌸 NAME 🌸

dwxe — the Allwinner EMAC 10/100/1Gb Ethernet device. that's the whole vibe. it's a network driver. it does ethernet. slay 💅

---

🦋 SYNOPSIS 🦋

dwxe* at fdt?
rgephy* at mii?

translation for the girlies: dwxe attaches at fdt? (that's the device tree situation) and rgephy attaches at mii? (that's the PHY situation). two lines, two attachments, very demure, very mindful 🎀

✨ DESCRIPTION ✨

so the dwxe driver provides support for various Ethernet controllers based on the Allwinner EMAC. and where do we find these gorgeous little controllers? on the Allwinner A64/H3/H5/H6/H616 SoCs. yes, that's five SoCs, and yes, I listed all of them, because we do not skip details in this house 🫶

the dwxe driver supports several media types, and you select them via the ifconfig(8) command. the supported media types are, in order, and I am not skipping a single one:

• media autoselect — attempt to autoselect the media type (and this is the default, so it's kind of the main character here 👑)
• media 1000baseT mediaopt full-duplex — use 1000baseT on copper, full duplex 🔥
• media 1000baseT mediaopt half-duplex — use 1000baseT on copper, half duplex
• media 100baseTX mediaopt full-duplex — use 100baseTX, full duplex
• media 100baseTX mediaopt half-duplex — use 100baseTX, half duplex

that's all five. count them. five. ate and left no crumbs 💀

ngl, if you're picking a media type manually instead of letting autoselect cook, make sure you actually know which duplex your switch wants, bestie. just saying 🙈
