fman_port_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… fman_port_init β€” a Kernel API Manual moment (section 9, bestie)

okay so like, welcome to the fman_port_init(9) glow-up ✨ this is the Kernel API Manual page, and we're about to make a FM Port module have a whole main character arc. no cap, it's giving "hardware whisperer" energy πŸŽ€


🌸 NAME 🌸

fman_port_init β€” honestly the name says it all, it's the init. the OG manpage didn't even write a description here (iconic low-effort behavior honestly πŸ’€), but like, it initializes the port. that's the vibe πŸ¦‹


✨ SYNOPSIS ✨

int fman_port_init (struct fman_port *port );

that's it, that's the whole call. one function, one pointer, so clean 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • port β€” a pointer to a FM Port module. that's your girl, the thing you're about to set up. hand her over and let the function do its thing πŸ’–

πŸ‘‘ DESCRIPTION πŸ‘‘

so what does it actually do? literally two things and both of them matter:

  • it initializes the FM PORT module by defining the software structure, and
  • it configures the hardware registers.

so like, it's setting up the bookkeeping and poking the actual silicon. both. at once. lowkey overachiever behavior and we love her for it 🌈


πŸ”₯ RETURN πŸ”₯

  • 0 on success β€” slay, we're so back πŸ’…
  • error code otherwise β€” bestie, if it's not 0, it's not okay, go check that code 😭
ngl there's no in-between here. 0 = win, anything else = look at the error code and deal with it fr fr.

the kernel file itself lives right here:

and the whole friend group, all of them, no one left out πŸ‘‘:


and that's the page, bestie πŸ§šπŸ’œ shoutout to the source/version line ./drivers/net/ethernet/freesca..., dated October 2026, and yes, this whole thing is fman_port_init(9) through and through β€” periodt. πŸ“β­
