✨ ufshcd_enable_ee ✨

okay so this is a page from the Kernel API Manual, section 9 β€” ufshcd_enable_ee(9) β€” and it's literally just one tiny function that does one very specific thing. short queen behavior, we respect it πŸ’…


🌸 NAME 🌸

ufshcd_enable_ee β€” enable exception event πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

int ufshcd_enable_ee (struct ufs_hba *hba , u16 mask );

πŸ’– ARGUMENTS πŸ’–

  • hba β€” the per-adapter instance, aka the one host controller bus adapter we're talking about here 🫢
  • mask β€” the exception event we wanna enable, bestie. that's the one ✨

πŸ‘‘ DESCRIPTION πŸ‘‘

so what this does is: it enables the corresponding exception event in the device β€” like, on the actual device side, not just in your head β€” so the device is allowed to alert the host when something critical goes down πŸ”₯

that's it. that's the whole vibe. it's giving "open the door so the device can yell at you if things go wrong," no cap πŸ’€


⭐ RETURN ⭐

  • zero on success πŸŽ‰
  • a non-zero error value on failure 😭

like every good well-behaved kernel function. periodt.


🌈 SEE ALSO 🌈

first up, the kernel file this whole family lives in: ./drivers/ufs/core/ufshcd.c 🧚

and now the entire friend group β€” yes, all of them, we are not skipping a single one, i don't do that πŸ™ˆ

like… that's the whole roster πŸ’€ going through it one by one is a lot, but we did it, and we didn't lose anybody πŸ«‘πŸ’–


ngl, this one's short but it matters β€” exception events are literally how the device tells you something critical happened, so enabling the right one is kinda iconic of it πŸ”₯

that's the whole page, bestie πŸŽ€ this cutie lives in ./drivers/ufs/core and got stamped October 2026 β€” mwah, love that for us πŸ’œπŸ§šβ€β™€οΈ
