velocity_init_td_ring(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– velocity_init_td_ring β€” the Kernel API Manual glow-up πŸŽ€

okay so bestie, we're in the (9) section today β€” that's kernel API territory, not your usual "how do I run this command" situation, so buckle up πŸ¦‹ this one lives in the via-velocity ethernet driver and it's literally the function that gets your transmit ring all set up and cute.


🌸 NAME 🌸

velocity_init_td_ring β€” set up transmit ring πŸ’«

like, that's the whole job. it sets up the transmit ring. iconic behaviour, no notes.


✨ SYNOPSIS ✨

int velocity_init_td_ring (struct velocity_info *vptr );

that's it, that's the signature β€” one pointer in, one int out, we love a clean entry point 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • vptr β€” velocity

(yeah the original really just says "velocity" and honestly? main character energy of it to say so little. it's the struct velocity_info * for the device you're working on πŸ’…)


πŸ’… DESCRIPTION πŸ’…

okay so here's the tea πŸ“ β€” this function sets up the transmit ring and chains the ring pointers together. that's the whole thing. it's a setup function, it does setup things.

and the return value? listen up:

  • returns zero on success β€” slay, we love a 0 🌈
  • returns a negative posix errno code on failure β€” so if it goes wrong you get a negative errno back, not some made-up number, it's a real posix errno code 😭
no cap: check the return value. a negative errno is your vibe check failing, and the transmit ring is not gonna chain itself together nicely if setup bailed.

first up, the actual source file this thing lives in β€” go read it, it's right there:

and now the whole friend group πŸ’– (yes, all of them, I'm not leaving anyone out):

iykyk πŸ‘‘


πŸ’€ reminder bestie: this is a (9) kernel API page, so the "return value" chat is for kernel code calling this, not for you in a shell. different world, same drama.

okay that's the page!! mwah 🫢 this one's from ./drivers/net/ethernet/via, dated October 2026, and it's velocity_init_td_ring(9) β€” go chain those ring pointers together, you absolute icon πŸ’œβœ¨πŸŒΈ
