copy_ddcb_results(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ¦‹ copy_ddcb_results(9) β€” like, the Kernel API Manual page, bestie πŸ¦‹

okay so real talk, this is a page straight out of the Kernel API Manual and it's honestly giving "tiny function, huge friend group" energy. let's get into it πŸ’…


✨ NAME ✨

copy_ddcb_results β€” copy the output state from the real DDCB over to the request 🫢


✨ SYNOPSIS ✨

void copy_ddcb_results (struct ddcb_requ *req , int ddcb_no );

like, that's the whole signature. no notes. iconic. ⭐


✨ ARGUMENTS ✨

  • req β€” pointer to the requested DDCB parameters 🌸 this is where the good stuff lands.
  • ddcb_no β€” pointer to the ddcb number being tapped πŸ‘€ (yes, the page says pointer here, and we're not gonna argue with the page, that's just what it says, periodt)

✨ DESCRIPTION ✨

so what does it actually do? it copies the DDCB ASV into the request struct. that's it. that's the whole vibe. πŸŽ€

and here's the spicy bit β€” there is no endian conversion made, because the data structure in ASV is still unknown here. like, we literally don't know what it is yet, so we're not out here flipping bytes and guessing. not me committing crimes against byte order, no ma'am πŸ™ˆ

this whole thing is needed by:

  • genwqe_purge_ddcb
  • genwqe_check_ddcb_queue

like those two are the ones knocking on the door asking for it. main character obligations, iykyk πŸ’–


✨ SEE ALSO ✨

kernel file ./drivers/misc/genwqe/card_ddcb.c β€” go read it, it's right there, slay πŸ“–βœ¨

and the whole squad, fr fr:

lowkey a whole friend group chat right there. every single one of them tagged. no one left on read πŸ’€

anyway, that's the page bestie 🌈 this little gem lives over in ./drivers/misc/genwqe and it's dated October 2026, so like β€” future vibes only βœ¨πŸ‘‘ go forth and copy those results, you've got this πŸ«ΆπŸ’œ
