tpacpi_check_quirks(9)

✨ tpacpi_check_quirks ✨

okay so bestie, this is a page from the Kernel API Manual — the tpacpi_check_quirks(9) one 💅 and it's literally about searching the BIOS/EC version on a list. stay with me, it's cute, i promise 🫶

🌸 SYNOPSIS 🌸

unsigned long tpacpi_check_quirks (const struct tpacpi_quirk *qlist ,
       unsigned int qlist_size );

🎀 ARGUMENTS 🎀

• qlist — the array of struct tpacpi_quirk. that's the list we're scrolling through, like a group chat of quirks 📱
• qlist_size — how many elements are in qlist. so, the headcount in that group chat 🔢

🦋 DESCRIPTION 🦋

so what it does: it iterates over a quirks list until it finds one that matches the ThinkPad's vendor, BIOS and EC model. that's it, that's the vibe check ✨

the match criteria is: vendor, ec and bios must match. all three, no cap. not two out of three, not "close enough" — all three or it's not the one 👑

💖 RETURN 💖

0 if nothing matches 😭 (no match, no sparkle) — otherwise it returns the quirks field of the matching struct tpacpi_quirk entry. the one that made it through the vibe check gets to shine 🌟

🌈 SEE ALSO 🌈

• Kernel file ./drivers/platform/x86/lenovo/thinkpad_acpi.c — go read the source, iykyk 📖
• usbc_security_query(9) — another one for your reading list 🧚

lowkey reminder bestie: the match is strict — vendor, ec and bios. if your entry fumbles even one of those, nobody's getting matched 💀

and that's the page!! made it out of ./drivers/platform/x86/lenovo, dated October 2026 🎀💜 slay, go forth and match those quirks fr fr 🌸
