πŸ’… of_fpga_region_parse_ov(9) ✨

okay so like, welcome to the Kernel API Manual, section 9 β€” yes bestie, this is the of_fpga_region_parse_ov page and it is literally the moment. grab a boba, we're parsing overlays 🧚


πŸŽ€ NAME πŸŽ€

of_fpga_region_parse_ov β€” parses and checks an overlay that got applied to a region, no cap πŸ’–


🌸 SYNOPSIS 🌸

struct fpga_image_info * of_fpga_region_parse_ov (struct fpga_region
*region , struct device_node *overlay );

yep that's the whole signature, she's giving function-returns-a-pointer-to-struct fpga_image_info, iconic πŸ‘‘


πŸ¦‹ ARGUMENTS πŸ¦‹

  • region β€” the FPGA region 🫢 like, the whole vibe arena we're working in
  • overlay β€” the overlay that got applied to the FPGA region ✨ the guest of honor

πŸ”₯ DESCRIPTION πŸ”₯

okay so picture this: you've got an overlay that's been applied to an FPGA region. what do we do? we parse the FPGA image specific info in the overlay and then do some checking. that's the whole bit. parsing + checking. lowkey the backbone of the operation πŸ’…

like, the function looks at what the overlay is telling us about the FPGA image, pulls that info out, and gives it a lil vibe check before anyone commits to anything πŸ™ˆ


⭐ RETURN ⭐

  • NULL β€” when the overlay doesn't direct us to program the FPGA πŸ«₯ (like, we're not doing that today bestie, thanks tho)
  • an fpga_image_info struct β€” when there is an image to program πŸ‘‘ that's the good stuff
  • an error code β€” when the overlay is invalid πŸ’€ yeah that's a problem
