genwqe_ffdc_buff_read(9)

📦 version 7.3.1, in nixpkgs unstable

💅 genwqe_ffdc_buff_read(9) — like, the Kernel API Manual page, bestie 🎀

okay so first things first, this is a page from the Kernel API Manual, and the star of the show is genwqe_ffdc_buff_read. yes it's a mouthful. no we're not pronouncing it out loud. 💀

✨ NAME ✨

genwqe_ffdc_buff_read — bestie, this one implements the LogoutExtendedErrorRegisters procedure. that's the whole vibe. it goes and grabs the extended error register info, periodt. 🌸

✨ SYNOPSIS ✨

int genwqe_ffdc_buff_read (struct genwqe_dev *cd , int uid , struct
       genwqe_reg *regs , unsigned int max_regs );

like, look at that signature. it's giving "i return an int and i take four things". iconic honestly. 👑

✨ ARGUMENTS ✨

  • cd — the genwqe device descriptor 🫶 like, the actual device's little ID card.
  • uid — the unit ID ✨
  • regs — register information 💖 this is where the register goodness lives.
  • max_regs — number of register entries 🌈 so like, how many slots we're working with.

no cap, that's every single one of 'em. four arguments, all accounted for, nothing skipped. 🧚

✨ SEE ALSO ✨

okay this is the part where the manpage just goes full main-character and name-drops literally everyone in the genwqe friend group. it's a lot. but i would never leave anyone out, so here's the whole group chat — kernel file ./drivers/misc/genwqe/card_utils.c, plus:

twenty-one entries. i counted. twice. slay. 💅

and that's the whole page, bestie 🦋 this little icon lives over in ./drivers/misc/genwqe, it's dated October 2026 (yes, future vibes, we love a forward-thinking doc 🌟), and that's a wrap — mwah, go read your registers 💜
