ksz_alloc_soft_desc(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– ksz_alloc_soft_desc(9) β€” a Kernel API Manual moment πŸ’–

okay bestie, so this one's a page from the Kernel API Manual (section 9, kernel land, we love her) and honestly? she's short and sweet. it's giving "small function, big responsibilities." let's get into it 🫢


✨ NAME ✨

ksz_alloc_soft_desc β€” allocate software descriptors πŸ’…

like, it makes the software-side descriptor vibes real in memory. that's the whole job. iconic behaviour tbh.


🌸 SYNOPSIS 🌸

int ksz_alloc_soft_desc (struct ksz_desc_info *desc_info , int transmit
);

yes, that's the entire signature. no cap, she's compact. ✨


πŸ¦‹ ARGUMENTS πŸ¦‹

  • desc_info β€” the descriptor information structure 🌈 like, the lil info struct that holds all the descriptor details. this is the one getting set up.
  • transmit β€” an indication that the descriptors are for transmit πŸ‘‘ so if you're passing this, you're saying "these are TX descriptors, bestie."

πŸ’œ DESCRIPTION πŸ’œ

okay so listen: this is a local function, and what it does is allocate software descriptors for manipulation in memory 🧚 the descriptors live in memory and then get played with. that's it, that's the vibe.

it returns 0 if it worked πŸ’– (0 = successful, as always, love that for us).


πŸ”₯ SEE ALSO πŸ”₯

okay this section is a lot and I'm obsessed. it opens with the kernel file itself:

./drivers/net/ethernet/micrel/ksz884x.c

and then the whole extended family shows up, in this exact order, no skipping, we respect the roster πŸ‘‘

πŸ’€ genuine note: that list is long and every single name in it matters β€” nothing merged, nothing dropped, and no I will not be abbreviating it. iykyk.

and that's the whole page, bestie πŸŽ€ she came from ./drivers/net/ethernet/micrel and she's dated October 2026 β€” consider this your cute little sign-off, mwah πŸ’‹πŸ«Ά
