qed_memcpy_to(9)

💅 qed_memcpy_to(9) — a Kernel API Manual moment 🎀

okay bestie, welcome to the qed_memcpy_to(9) page, like the actual kernel API manual energy, and honestly? it's a short one but she serves. this is the "copy stuff INTO the BAR" girlie, and yes she has a p_ptt and yes we're gonna talk about it 💖

---

✨ NAME ✨

qed_memcpy_to — copy n bytes to BAR using the given ptt 🫶

like, that's the whole assignment. copy. bytes. to the BAR. with a ptt. iconic.

---

🌸 SYNOPSIS 🌸

void qed_memcpy_to (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt ,
u32 hw_addr , void *src , size_t n );

she's void, she takes five things, no cap 🤷‍♀️✨

---

🦋 ARGUMENTS 🦋

look, the original docs are mad terse here, and I'm not about to invent lore, so here's exactly what you get:

• p_hwfn — HW device data. 💻 (the hardware device's whole situation, basically her main character data)
• p_ptt — P_ptt. 🎀 (yes. that's the description. we love a minimal queen)
• hw_addr — HW address. 📍 (the address, on the hardware)
• src — Source. 📤 (where the bytes are coming from)
• n — N. 🔢 (the count. the number. the n.)

ngl the upstream descriptions are giving "wrote this at 3am before the merge window closed" 😭 but we're respecting the source material fr fr — no extra guesses added, bestie's honour 💅

---

💀 RETURN 💀

Void. 🕳️

that's it. nothing comes back. she does the thing and dips, zero notes, no return value, main character exit 🌈
