sdio_retune_crc_enable(9)

📦 version 7.3.1, in nixpkgs unstable

💅 sdio_retune_crc_enable — a Kernel API Manual moment ✨

okay so bestie, pull up a chair, because we're in the Kernel API Manual today and honestly? this one is short and sweet and kind of iconic for it 🎀

✨ NAME ✨

sdio_retune_crc_enable — re-enable retuning on CRC errors, no cap 🔥

🦋 SYNOPSIS 🦋

void sdio_retune_crc_enable (struct sdio_func *func );

like, that's it. that's the whole signature. she's giving minimalism 💅

🌸 ARGUMENTS 🌸

  • func — the SDIO function attached to the host 🫶 (yes it's struct sdio_func *, yes you gotta pass it, no there's no way around it)

💖 DESCRIPTION 💖

so here's the tea, bestie: this is the complement to sdio_retune_crc_disable. that's it. that's the description. the docs said what they said and they said it in one sentence 😭

think of it as the "undo" button for the disable one — you disabled the retuning-on-CRC-errors behaviour, and now you're turning it back on. slay ✨

no extra lore in here, babes. the manpage keeps it mysterious. i'm not gonna invent behaviour that isn't written down — that's not the vibe, fr fr 🙈

🔮 SEE ALSO 🔮

the lore dump, the whole friend group, the kernel file ./drivers/mmc/core/sdio_io.c — and every single one of these icons 👑

like go read those too, they're all part of the same little universe 🌈⭐

and that's the whole page, bestie!! sourced straight from ./drivers/mmc/core, version date October 2026 — signed, sealed, delivered, and honestly kind of obsessed with how short this one was 💜 🧚‍♀️💫
