📦 version 7.3.1, in nixpkgs unstable

💅 fpga_mgr_buf_load(9) — like, the whole Kernel API Manual but make it make sense

okay bestie, welcome to the glow-up of fpga_mgr_buf_load — the kernel function that takes your FPGA from "just sitting there" to "fully configured and serving looks" ✨ this is part of the Kernel API Manual, so grab your matcha and let's go 🍓

✨ NAME ✨

fpga_mgr_buf_load — load fpga from image in buffer 🎀

🌸 SYNOPSIS 🌸

int fpga_mgr_buf_load (struct fpga_manager *mgr , struct fpga_image_info
*info , const char *buf , size_t count );

🦋 ARGUMENTS 🦋

  • mgr — the fpga manager 🫶 (this is your main character struct, no cap)
  • info — fpga image info ✨ (all the deets about the image)
  • buf — buffer contain fpga image 💖 (yes, the literal bytes, held in a buffer)
  • count — byte count of buf 🌈 (how many bytes we're working with, fr fr)

💜 DESCRIPTION 💜

so what this does is: it steps the low level fpga manager through the device-specific steps of getting an FPGA ready to be configured, writing the image to it, then doing whatever post-configuration steps necessary 🔥 like a full makeover sequence — prep, apply the look, then the finishing touches 💅

and here's the important bit, ngl: this code assumes the caller got the mgr pointer from of_fpga_mgr_get and checked that it is not an error code 😭 like please do that check, bestie. don't come in here with a bad pointer, it is not the vibe.

⭐ RETURN ⭐

0 on success 🎉, negative error code otherwise 💀 (iykyk, always check your return values)
