setup_qp_page_tables(9)

💅 setup_qp_page_tables(9) — like, the Kernel API Manual entry, bestie

okay so picture this: it's a (9) page in the Kernel API Manual, the star of the show is setup_qp_page_tables, and it lives in ./drivers/scsi/bnx2i. she's giving niche-but-iconic, and honestly? we're obsessed. let's get into it 🫶

---

✨ NAME ✨

setup_qp_page_tables — the iscsi QP page table setup function. literally her whole thing. no notes. 💅

---

🌸 SYNOPSIS 🌸

void setup_qp_page_tables (struct bnx2i_endpoint *ep );

that's it. that's the whole signature. one arg, void return, main character energy only ✨

---

🎀 ARGUMENTS 🎀

• ep — the endpoint (transport identifier) structure. that's your girl right there, the transport identifier herself 💖

---

🦋 DESCRIPTION 🦋

so what does she do? she sets up page tables for SQ/RQ/CQ. yes, all three, no crumbs left. 🍓

and here's where it gets spicy — the endianness is not one-size-fits-all, bestie:

• 1G/sec devices (5706/5708/5709) require a 64-bit address in big endian format 🔥
• 10G/sec (57710) requires the PT in little endian format 💀

so fr fr, know your device before you go flipping bytes around. the 1G girls and the 10G girl are simply not built the same, and that's on periodt.
