💅 am33xx_restart(9) — Kernel API Manual ✨

okay so bestie, welcome to the am33xx_restart page — it lives in section 9 of the Kernel API Manual and it's genuinely one of those tiny-but-iconic little functions that just does one thing and does it slayfully 🎀

---

✨ NAME ✨

am33xx_restart — trigger a software restart of the SoC 💫

like, that's it. that's the whole job. press the big red button, but in code 🫶

---

🌸 SYNOPSIS 🌸

void am33xx_restart (enum reboot_mode mode , const char *cmd );

no cap, it returns nothing, it takes two things, and it's about to end your SoC's whole career 😭🔥

---

🦋 ARGUMENTS 🦋

• mode — the "reboot mode", fr. for the deets on this one, go look at arch/arm/kernel/{setup,process}.c — that's where the lore lives 👑
• cmd — this one gets passed down from the userspace program that's rebooting the system (if one was provided, that is 💅). so like, if userspace had something to say, this is where it says it.

---

💖 DESCRIPTION 💖

so what does it actually do? it resets the SoC. periodt. 💀

as for cmd, bestie, go check the 'reboot' syscall over in kernel/sys.c — that's the icon that hands it over in the first place 🌈

and the return value? none. there isn't one. no return value, no notes, no follow-up questions. main character energy only 😌✨

🧚 SEE ALSO 🧚

• Kernel file ./arch/arm/mach-omap2/am33xx-restart.c — literally the whole source of truth, go read it, it's giving required reading 📖💜

ngl this page is short but it ate. small function, clear vibes, zero ambiguity 🍓

---

and that's the vibe check bestie 🫶 this page came from ./arch/arm/mach-omap2 (the source/version situation, iykyk), dated October 2026, and it's forever filed under am33xx_restart(9) 👑💫 go forth and restart responsibly 💅
