zynqmp_pm_g...zone_version(9)

🦋 zynqmp_pm_get_trustzone_version — Kernel API Manual 🦋

okay so real talk, the page title up top got literally chopped into zynqmp_pm_g...zone_version(9) and honestly? mysterious. icon behavior. but the full name is down in NAME and we're gonna get into it. this one's from the Kernel API Manual, and it is such a little function. let's go 💅

---

✨ NAME ✨

zynqmp_pm_get_trustzone_version — Get secure trustzone firmware version 🎀

like, that's it. that's the whole vibe. she fetches the version of the secure trustzone firmware. no cap.

---

🌈 SYNOPSIS 🌈

int zynqmp_pm_get_trustzone_version (u32 *version );

look at her. one argument. returns an int. clean, minimal, main character energy fr fr.

---

💖 ARGUMENTS 💖

• version — Returned version value ✨ — this is where the version comes back out, so you gotta hand her a pointer to a u32 and she'll fill it in. she's not asking, she's telling (politely).

---

🔥 RETURN 🔥

Returns status, either success or error+reason 💀 — so yeah, check that return value, bestie. success is success, and error comes with a reason attached. not me ignoring a return code… couldn't be me 🙈

the way that list just keeps going 😭 she said "and my friends" and brought the entire kernel. iykyk.

and that's the page!! 🫶 sourced straight from ./drivers/firmware/xilinx, dated October 2026, and the title up top still reads zynqmp_pm_g...zone_version(9) because we love a dramatic abbreviation. periodt. 💜
