💖 qed_memcpy_from — the kernel API manual, bestie edition 💖

okay so welcome to the Kernel API Manual page for qed_memcpy_from(9) 🎀 pull up a chair, grab a strawberry, and let's get into it ✨

🌸 NAME 🌸

qed_memcpy_from — copy n bytes from BAR using the given ptt. that's the whole gig, no cap 💅

---

🦋 SYNOPSIS 🦋

void qed_memcpy_from (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt ,
void *dest , u32 hw_addr , size_t n );

yes bestie that's the exact signature, i typed it out character for character because i love you 🫶

✨ ARGUMENTS ✨

• p_hwfn — HW device data 💖 this is your hardware function struct, the whole vibe of the device lives here.
• p_ptt — P_ptt 🌈 the ptt you're passing in, that's it, that's the arg.
• dest — Destination 🎯 where the bytes are headed (in memory, not on a trip).
• hw_addr — HW address 💻 the hardware-side address you're reading from.
• n — N 🔢 literally the number of bytes. iconic one-letter parameter behavior, we stan.

👑 RETURN 👑

Void. it returns nothing. no value, no drama, no return statement energy — it's giving void fr fr 💀
