fpga_mgr_load(9)

📦 version 7.3.1, in nixpkgs unstable

💖 fpga_mgr_load — bestie, it's FPGA loading time 💖

okay so this is a page from the Kernel API Manual, section 9 — yes, the kernel one, we're in the big leagues now. Anyway, sit down, grab a snack 🍓, because this little function is genuinely doing main character work.

✨ NAME ✨

fpga_mgr_load — load an FPGA from a scatter/gather table, a buffer, or firmware 🧚

🌸 SYNOPSIS 🌸

int fpga_mgr_load (struct fpga_manager *mgr , struct fpga_image_info *info );

like, that's the whole call. two args. iconic behaviour honestly 💅

🎀 ARGUMENTS 🎀

  • mgr — the fpga manager, aka your guy. the one doing the managing. 🫶
  • info — the fpga image information. yep, the info about the image. it's giving "descriptive name" and we love that for it 💜

🦋 DESCRIPTION 🦋

So here's the vibe: fpga_mgr_load loads the FPGA from an image, and that image is the one indicated in info. 📸

And if it works? If it actually works?? The FPGA ends up in operating mode. that's it. that's the goal. not me getting emotional over a successful load 😭✨

no cap, "operating mode" is the whole payoff here — that's the win condition, bestie. 🏆

🌈 RETURN 🌈

  • 0 on success 🎉
  • negative error code otherwise 💀

so like, zero = slay, negative = go read your logs and have a little cry. both are valid. 🔥

and then the whole friend group of related functions, all here so you can go down the rabbit hole:

like, that's the entire group chat. get to know them. 🫶💖

and that's the page!! 💅 this little gem lives in ./drivers/fpga and the version we're looking at is dated October 2026 — so yeah, future-dated documentation, very mysterious, very demure, very cutesy 🎀✨ go load some FPGAs, bestie, you've got this! 🌸🦋
