📦 version 7.3.1, in nixpkgs unstable

💅 __devm_fpga_mgr_register_full(9) — the Kernel API Manual, but make it make sense ✨

okay so bestie, buckle up, because this one is a devres function and honestly? she's iconic for it. this is the resource-managed lil sibling in the FPGA manager registration family, straight out of the Kernel API Manual, and she is here to save you from yourself (affectionate) 🫶

🎀 NAME 🎀

__devm_fpga_mgr_register_full — the resource-managed variant of fpga_mgr_register(). yes, the double-underscore one. she's fancy. periodt. 💅

🌸 SYNOPSIS 🌸

struct fpga_manager * __devm_fpga_mgr_register_full (struct device
*parent , const struct fpga_manager_info *info , struct module *owner );

look at her. three args, one pointer returned, zero chaos (theoretically 😭).

✨ ARGUMENTS ✨

  • parent — the fpga manager device, coming at you from pdev. she's the one who's gonna be managing things, so be nice to her 💖
  • info — the parameters for the fpga manager. this is where all the config lives, so pack it thoughtfully 🎀
  • owner — the owner module containing the ops. yes, that's your module. main character energy, bestie 👑

🔥 RETURN 🔥

you get an fpga manager pointer on success 🎉 and a negative error code otherwise 😭 — so like, always check. always. no cap.

🦋 DESCRIPTION 🦋

okay so here's the tea: this is the devres variant of fpga_mgr_register_full, for which the unregister function will be called automatically when the managing device is detached. 🧚‍♀️

that's it. that's the whole vibe. you register, devres remembers to unregister for you when the device goes poof — no manual cleanup arc, no leaked resources, no 3am debugging session. she ate. 💅✨

lowkey important: automatically is doing a lot of heavy lifting here — that's the entire point of the devm flavor, so don't go calling unregister yourself on top of it 🙈

like a whole friend group honestly, they all show up together 💜

and that's the whole page bestie!! this lore dropped October 2026, lives in ./drivers/fpga, and was served up fresh from the Kernel API Manual — see you in the next man page, mwah 🍓💖
