i40e_pci_sriov_configure(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

i40e_pci_sriov_configure — and bestie, the description after the dash is… literally nothing. Empty. Blank. The manpage said i40e_pci_sriov_configure - and then dipped 😭 so I'm not gonna sit here and make up a tagline for it. That's the whole NAME section, no cap.

(This lil page lives in the Kernel API Manual, mwah 🎀)

✨ SYNOPSIS ✨

int i40e_pci_sriov_configure (struct pci_dev *pdev , int num_vfs );

She's an int-returning girlie, two args, very demure 💅

🦋 ARGUMENTS 🦋

  • pdev — pointer to a pci_dev structure, okay so that's your PCI device situation right there 🫶
  • num_vfs — number of VFs to allocate. like, how many VFs do you want. this many. that's the number 🌸

🔥 DESCRIPTION 🔥

Ok so the actual tea: this thing enables VFs, or changes how many VFs you've got. Both. Either. The way it just handles it 🔥

And the vibe check on when it gets called: it's called when the user updates the number of VFs in sysfs. That's it, that's the trigger — user pokes sysfs, this function wakes up and does the thing. slay 💅

👑 SEE ALSO 👑

Sit down for this one bestie, because the cross-reference list is huge and I'm listing every single one, periodt. First up, the kernel file herself:

  • ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c

And now the whole friend group (all (9), all here, no one left out) 🌈:

Ninety-five references. Ninety-five!! the way this page said "here's everyone she knows" and then listed the entire friend group 😭💀 iconic honestly.

And that's the whole page, bestie — originally served up from ./drivers/net/ethernet/intel/i40e, dated October 2026, in that Kernel API Manual of ours. mwah, go read some source, ily 🫶✨💜
