adf_cleanup_etr_data(9)

💖 adf_cleanup_etr_data — bestie edition 💖

okay so this is a page from the Kernel API Manual, and honestly? it's a short one but she matters. it's all about tidying up after your acceleration device, and we're gonna get into it 🎀

---

✨ NAME ✨

adf_cleanup_etr_data — clear transport rings for acceleration device 💅

like, the cleanup crew but for kernel rings. no cap.

---

✨ SYNOPSIS ✨

void adf_cleanup_etr_data (struct adf_accel_dev *accel_dev );

that's it. that's the whole vibe. one function, one argument, no drama 🦋

---

✨ ARGUMENTS ✨

• accel_dev — pointer to acceleration device. literally just a pointer to your accel device 🫶 that's the whole thing, she's not complicated.

---

✨ DESCRIPTION ✨

so what does she do? the function clears the communications channels (a.k.a. the rings) of the acceleration device accel_dev 🌸

it's giving "log out, close your tabs, clear the group chat" energy — except it's rings, and it's kernel land 💀

heads up: this one is meant to be used by QAT device specific drivers. so like, iykyk — if you're not in that lane, this isn't your girl 🙈

---

✨ RETURN ✨

void 👑

she returns nothing. she gives nothing back. she simply does the work and leaves. main character energy fr fr ✨

okay that's the whole page!! 🎀 this came out of the kernel API manual, source/version vibe is ./drivers/crypto/intel/qat/qat... and the date on it is October 2026 — so mark your calendars, she's from the future 💖✨🦋 go forth and clean up those rings, ily, bye 💜👑
