DBCIOCNONCE(9)

💅 NAME 💅

okay so bestie, this is DBCIOCNONCE(9) from the Kernel API Manual, and it's literally the move where you fetch a nonce from the PSP for authenticating commands. ✨

• if a nonce is fetched without authentication, it can only be utilized for one command. one. single. command. periodt. 💀
• if a nonce is fetched with authentication, it can be used for multiple requests. slay, reusable nonce energy. 👑

✨ SYNOPSIS ✨

ngl, the whole synopsis is just this iconic little line:

DBCIOCNONCE

that's it. that's the vibe. 🎀

🌸 SEE ALSO 🌸

go look at these besties for the full lore 🫶:

• Kernel file ./include/uapi/linux/psp-dbc.h
• AMD Dynamic Boost Control (DBC) interface(9)
• struct dbc_user_nonce(9)
• struct dbc_user_setuid(9)
• struct dbc_user_param(9)
• DBCIOCUID(9)
• DBCIOCPARAM(9)
• enum dbc_cmd_msg(9)

iykyk, that header file is lowkey main character energy here. 💜

mwah 💖 this page lives in ./include/uapi/linux, dated October 2026, and it's literally DBCIOCNONCE(9) — bye bestie! 🦋
