nfp_cpp_area...oc_with_name(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nfp_cpp_area_alloc_with_name(9) — from the Kernel API Manual

okay bestie, so this one is a kernel API manual page, and the function we're obsessing over is nfp_cpp_area_alloc_with_name ✨

✨ NAME ✨

nfp_cpp_area_alloc_with_name — allocate a new CPP area 🎀

🌸 SYNOPSIS 🌸

struct nfp_cpp_area * nfp_cpp_area_alloc_with_name (struct nfp_cpp *cpp
 , u32 dest , const char *name , unsigned long long address , unsigned
 long size );

🦋 ARGUMENTS 🦋

  • cpp — the CPP device handle, your whole entry point to the device 🫶
  • dest — NFP CPP ID, u32 energy
  • name — name of region, literally just what you're calling this thing
  • address — address of region 📍
  • size — size of region

💖 DESCRIPTION 💖

So what this does is allocate and initialize a CPP area structure for you. Iconic. But listen — the area isn't usable right away 😭 it must later be locked down with an 'acquire' before it can be safely accessed. No shortcuts, no cap.

⭐ NOTE ⭐

address and size must be 32-bit aligned values. fr fr, don't skip this one 🚨

👑 RETURN 👑

Returns an NFP CPP area handle, or NULL 💀 (so, y'know, check it).

🌈 SEE ALSO 🌈

The kernel file lives at ./drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c 🧚
