💅 irdma_sc_alloc_stag — Kernel API Manual ✨

okay so bestie, welcome to the glamorous world of memory-region STAG allocation in the irdma driver. this page is part of the Kernel API Manual, and it's basically the "reserve me a spot in the table" moment for a memory region (MR). no cap, it's a small function with big main-character energy 👑

🌸 NAME 🌸

irdma_sc_alloc_stag — mr stag alloc 🎀

literally it's the memory-region STAG allocator. that's the whole vibe.

🦋 SYNOPSIS 🦋

int irdma_sc_alloc_stag (struct irdma_sc_dev *dev , struct
       irdma_allocate_stag_info *info , u64 scratch , bool post_sq );

it returns an int, bestie. that's your vibe check on whether things worked 💫

✨ ARGUMENTS ✨

  • dev — the sc device struct 🖥️ — your whole device situation, passed in as struct irdma_sc_dev *.
  • info — stag info 📋 — a struct irdma_allocate_stag_info * carrying all the STAG details. it's giving "paperwork but make it C".
  • scratch — u64 saved to be used during cqp completion 🗂️ — you stash this now, and it comes back to hang out later when the CQP completes. lowkey iconic of it.
  • post_sq — flag for cqp db to ring 🔔 — a bool that says whether the CQP doorbell should ring. yes ma'am, ring it.
