set_bytes_swap(9)

💅 set_bytes_swap(9) — a Kernel API Manual moment

okay so bestie, welcome to set_bytes_swap 💖 we're in the Kernel API Manual today (yes, the manual section 9 one, the kernel-internals girlies know) and this little function is genuinely iconic. it does exactly one thing and it does it slayfully. no cap.

---

✨ NAME ✨

set_bytes_swap — Set byte order of all setup-finalize descriptors. 🎀 that's it. that's the whole gig. she's a one-job queen and she executes.

---

🌸 SYNOPSIS 🌸

void set_bytes_swap (struct cc_hw_desc *pdesc , bool config );

like, look at her. void return — she doesn't return anything, she doesn't need to, she just does 🦋

---

💅 ARGUMENTS 💅

• pdesc — Pointer to HW descriptor struct. it's the hardware descriptor struct pointer, bestie, that's the thing you're handing her 💫
• config — True to enable byte swapping. so like, pass true and the bytes get swapped, periodt 🔥 pass false and… you know. no swap. the vibe check is in your hands.
