💅 ufshcd_compl_one_cqe(9) — the "handle a completion queue entry" page 💅

okay so bestie, welcome to the Linux Kernel API Manual, and today's main character is ufshcd_compl_one_cqe. It lives over in ./drivers/ufs/core/ufshcd.c — yes, that file, the big one, the iconic one. Put your hair up, we're doing UFS internals. 🎀

✨ NAME ✨

ufshcd_compl_one_cqe — handle a completion queue entry

Like, one entry. One CQE. She's doing her single little job and she's doing it gorgeously. 🦋

🌸 SYNOPSIS 🌸

void ufshcd_compl_one_cqe (struct ufs_hba *hba , int task_tag , struct
cq_entry *cqe );

Returns nothing (void) — she gives, she doesn't take. periodt. 💅

💖 ARGUMENTS 💖

  • hba — the per adapter instance, aka the whole vibe of this host bus adapter. Think of it as the group chat and everything in it. 👑
  • task_tag — the task tag of the request that's being completed. It's the little ID that says this request, not the other one, bestie, please don't mix them up 😭
  • cqe — pointer to the completion queue entry. That's the actual envelope being opened. 💌

🌈 SEE ALSO 🌈

Okay this is the part where I need you to sit down. The kernel file is ./drivers/ufs/core/ufshcd.c, and the cross-reference list is long — I'm keeping every single one because we do not ghost family. 🫶

Interrupts & HBA basics — the "who's awake" girlies

Power, clocks & QoS — the high-maintenance section (affectionate) 💀

UPIUs, queries & memory — her intellectual era 🧚

DME / UIC power mode & link bring-up — the glow-up arc ✨

Exception events, bkops, errors & TM — the crisis-management queens 🔥

Probe, suspend/resume & teardown — the whole life cycle, she contains multitudes 😭

ngl bestie, that's a LOT of cross-references, but every single one is here and in the original order, so the vibe check passes ✅

mwah 💜 that's the whole page. sourced straight from ./drivers/ufs/core, dated October 2026, and no cap — nothing got left out, not one flag, not one name. go forth and complete those queue entries, queen. 👑🦋✨
