💅 zynqmp_pm_write_ggs(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the Xilinx/ZynqMP firmware world and you just need to put a value somewhere that survives. That's this function. It's a lil PM API (power management, not "private message", tho honestly same energy) and it writes to global general storage — ggs for the girlies who like abbreviations. Let's get into it ✨

✨ NAME ✨

zynqmp_pm_write_ggs — the PM API for writing global general storage (ggs). yes that's really what it stands for. no I will not be elaborating further, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

int zynqmp_pm_write_ggs (u32 index , u32 value );

like look at her. two u32s, returns an int. clean. minimal. iconic. 👑

🦋 ARGUMENTS 🦋

  • index — the GGS register index. which slot you're writing to, bestie. pick responsibly 💖
  • value — the register value to be written. this is the actual thing going into the slot. slay 💅

💜 DESCRIPTION 💜

So what does she do? This function writes value to the GGS register. That's it. That's the whole arc. no cap, no side quests, no hidden lore — it writes the value to the GGS register and minds her own business 🧚

⭐ RETURN ⭐

Returns status — either success, or error+reason. so like, she'll tell you if it went great, and she'll also tell you why if it didn't. communication queen fr fr 🫶

🌈 SEE ALSO 🌈

okay this is the part where I need you to sit down, because the list is LONG and every single one of these deserves a lil shoutout. this function is part of a whole friend group 💀

The kernel file lives at ./drivers/firmware/xilinx/zynqmp.c and honestly it's the main character — but here's everyone:

like?? that's a whole roster. and yes I listed every single one, because we do NOT gatekeep on this page 💖✨

ok but fr fr — if you're writing to GGS you probably wanna also peek at zynqmp_pm_read_ggs(9) so you can check your work. go read her too, she's lovely 🫶

and that's the page!! special shoutout to ./drivers/firmware/xilinx for the source, October 2026 for the date, and zynqmp_pm_write_ggs(9) herself for being the moment. mwah 💋 go write some registers, bestie 🌟
