💅 arm_smccc_get_soc_id_revision — Kernel API Manual

okay so bestie, we're in the Kernel API Manual today and this one is a lil page from arm_smccc_g..._id_revision(9) — yes the title is literally truncated with an ellipsis in the header, that's just how it is, we don't make the rules 💀. Sit down, this one's short and sweet.

🌸 NAME 🌸

arm_smccc_get_soc_id_revision — and that's it. That's the whole name section. The original literally leaves the description blank after the dash, so no, I'm not gonna invent one for you babe, that would be lying ✨

---

🎀 SYNOPSIS 🎀

s32 arm_smccc_get_soc_id_revision (void );

that's the whole function signature, she's a s32 return and takes no arguments, iconic minimalism 🫶

---

🦋 ARGUMENTS 🦋

• void — no arguments. none. zero. the void. she needs nothing from you, she's independent like that 👑

---

✨ DESCRIPTION ✨

So what does she do? She returns the SOC ID revision — that's it, straightforward, no cap 💖

But here's the important bit (the vibe check, if you will): when ARM_SMCCC_ARCH_SOC_ID is not present, she returns SMCCC_RET_NOT_SUPPORTED.

so if you're on a platform that doesn't have that SMCCC arch thing going on, don't be surprised when you get SMCCC_RET_NOT_SUPPORTED back — that's not a bug, that's the documented behavior, fr fr 🙈
