SFSIOCUPDATEPKG(9)

✨ SFSIOCUPDATEPKG ✨

okay bestie, welcome to SFSIOCUPDATEPKG from the Kernel API Manual — section 9, no cap. this one is all about updating package/payload ASP loads, verifying the SFS package, and executing it. iconic behavior, honestly.

🎀 NAME 🎀

SFSIOCUPDATEPKG updates package/payload ASP loads, verifies the SFS package, and executes it. periodt.

by default, the SFS package/payload is loaded from /lib/firmware/amd, but you can point it at a different firmware loading path using the kernel parameter firmware_class.path — or you can customize the firmware loading path with this sysfs file:

/sys/module/firmware_class/parameters/path

so yeah, default vibe is /lib/firmware/amd, but alternatives are very much allowed. 💅

🌸 SYNOPSIS 🌸

🦋 SEE ALSO 🦋

• Kernel file ./include/uapi/linux/psp-sfs.h struct sfs_user_get_fw_versions(9), struct sfs_user_update_package(9), SFSIOCFWVERS(9)

go read those too, bestie — they're part of the lore. 📚✨

no extra drama here: every path, parameter, sysfs file, and reference above is exactly the tea from the original page. 🫶

mwah 💋 — this page comes from ./include/uapi/linux (that's the source/version line), dated October 2026. slay. 👑
