💖 mmcsd — the MMC & SD memory card driver 💖

okay bestie, so this one lives in the Kernel Interfaces Manual (section 4, kernel interfaces, iykyk) and it's genuinely so cute and simple, no cap. It's about your memory cards. Yes, those memory cards. Let's get into it ✨

🌸 NAME 🌸

mmcsd — the MMC and SD memory card driver 🎀

✨ SYNOPSIS ✨

Like, this is the whole entire summoning ritual. That's it. That's the vibe:

device mmcsd

🦋 DESCRIPTION 🦋

So the mmcsd driver implements a direct access block device for MMC and SD memory cards. 💅

That's literally it. It's the thing that makes your card show up as a block device so the rest of the system can just… talk to it. Main character energy, lowkey. 🔥
