💾 zynqmp_pm_write_pggs — Kernel API Manual era 💾

okay so bestie, buckle up, we're diving into zynqmp_pm_write_pggs(9) — a little function from the Kernel API Manual that is, and I cannot stress this enough, literally the whole personality of "write one thing into one register." no cap. 🫶

✨ NAME ✨

zynqmp_pm_write_pggs — the PM API for writing to persistent global general storage (pggs). yes that's three g's and one p and she ate 💅

🦋 SYNOPSIS 🦋

int zynqmp_pm_write_pggs (u32 index , u32 value );

look at her. two arguments. no drama. iconic. ✨

🌸 ARGUMENTS 🌸

  • index — the PGGS register index 💖 this is the which one of it all
  • value — the register value to be written ✨ this is the what goes in there

that's it that's the whole vibe check. one tells her where, one tells her what. 🎀

👑 DESCRIPTION 👑

so what does she actually do? she writes value to the PGGS register. periodt. 💅

ngl bestie this is a short one — the manpage is not gonna give you a whole novel here. she writes the value to the register and that's the entire plot. no filler, no secret third thing, no extra behaviour described anywhere. 🙈

⭐ RETURN ⭐

returns status — either success, or error+reason 😭 so like, check it. don't just yolo it and walk away. fr fr.

🧚 SEE ALSO 🧚

okay this is the part where the manpage goes FULL group-chat-tag-everyone mode. the kernel file is ./drivers/firmware/xilinx/zynqmp.c and here's the entire friend group, no one left out, i checked twice 💀:

and that's the whole page bestie!! go forth and write your persistent global general storage 💖

okay final sign-off, cute style: this little love letter lives in ./drivers/firmware/xilinx, and it's dated October 2026 — so yes, it's from the future, and yes, it's still just writing a value to a register. mwah 🎀💜🦋✨
