💳 WBSD(4) — like, the SD card driver for your Winbond reader, bestie ✨

okay so this is a kernel interfaces manual page, and the vibe is very niche but honestly kind of iconic. sit down, grab a strawberry 🍓, and let me tell you about wbsd.

🌸 NAME 🌸

wbsd — the Winbond W83L518D/W83L519D SD memory card interface driver. that's it, that's the whole name. short, sweet, slays 💅

---

⭐ SYNOPSIS ⭐

wbsd* at ebus?
sdmmc* at wbsd?

like literally just those two lines. wbsd attaches at ebus? (the question mark is doing its thing, don't question it), and then sdmmc* attaches at wbsd?. nesting dolls but make it kernel config 🪆

---

🦋 DESCRIPTION 🦋

so the wbsd driver provides support for the SD memory card interface of the Winbond W83L518D/W83L519D integrated media reader. yes, the integrated media reader — it's giving "built into the machine and proud of it" 👑

and the sdmmc(4) subsystem is the main character that actually performs the SD/MMC transactions, communicating with whatever MMC, SD, SDHC, or SDIO devices are inserted into the SD slot. wbsd is lowkey the supportive bestie and sdmmc(4) does the talking, iykyk 🤝
