💅 ufshcd_reset_and_restore — Kernel API Manual ✨

okay so bestie, welcome to the glow-up doc for ufshcd_reset_and_restore(9) from the Kernel API Manual — this is the UFS universe's ultimate "have you tried turning it off and on again" moment, and honestly? iconic. 🎀

🌸 NAME 🌸

ufshcd_reset_and_restore — reset and re-initialize host/device 🦋

✨ SYNOPSIS ✨

int ufshcd_reset_and_restore (struct ufs_hba *hba );

bestie look at that signature. she's short, she's simple, she takes exactly one pointer and returns an int. no notes. 💅

🫶 ARGUMENTS 🫶

  • hba — the per-adapter instance, aka the main character of this whole operation 🌟

💖 DESCRIPTION 💖

So here's the vibe: this function resets and recovers the device and the host, and then re-establishes the link between them. 🔥

Think of it as the full factory-reset-and-reconnect arc. It's literally the move you pull when the communication has completely fallen apart — the manpage says it's "helpful to recover the communication in fatal error conditions", and ngl, that's the whole point. 🚨 When things are giving catastrophic breakdown energy, this is the one that hits the refresh button on the relationship and gets everyone talking again. fr fr. 💀➡️💖

⭐ RETURN ⭐

  • zero on success 🥳
  • non-zero on failure 😭

that's it, that's the contract. no cap.

👑 SEE ALSO 👑

all the neighbors, all the lore. Kernel file ./drivers/ufs/core/ufshcd.c and literally the entire UFS extended family, in order, exactly as the ancestors wrote them 🧚

🌈 and that's the whole page, bestie. this lil gem lives over in ./drivers/ufs/core, dated October 2026, in the Kernel API Manual, and it's filed under ufshcd_reset_and_restore(9) in case you ever need to find her again. slay, stay hydrated, and remember: when in doubt, reset and re-establish the link. periodt. 💜🎀✨
