ice_reset_all_vfs(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ice_reset_all_vfs(9) — reset all allocated VFs in one go 💖

okay so first things first, bestie: this page lives in the Kernel API Manual, and the function we're simping over today is ice_reset_all_vfs. It's giving "one big group reset, no chaos" energy and honestly? iconic. 🌈

✨ SYNOPSIS ✨

void ice_reset_all_vfs (struct ice_pf *pf );

no cap, that's the whole signature — she's a void, she takes one pointer, and she handles her business. 💅

🎀 ARGUMENTS 🎀

  • pf — pointer to the PF structure. that's it, that's the whole argument list, and she ate. 🍓

🦋 DESCRIPTION 🦋

so the whole vibe here is: reset all the VFs at once, in response to a PF reset or any other device reset. group reset. all of them. together. periodt. 👑

here's the order of operations, and it lowkey matters:

  1. First, tell the hardware to reset each VF. 🫶
  2. Then do all the waiting in one chunk — like, one big collective wait, not a million tiny ones. 😭
  3. And finally, finish restoring each VF after the wait. ✨

why do we care? because this is genuinely useful during PF routines which need to reset all VFs — otherwise you'd have to perform these resets in a serialized fashion, which sounds exhausting honestly. this way everything's parallel-ish and the code isn't sitting there doing them one at a time like some kind of Victorian era. 💀

🔥 SEE ALSO 🔥

the kernel file, for the brave:

Kernel file ./drivers/net/ethernet/intel/ice/ice_vf_lib.c

and the whole friend group, fr fr — every single one of these is invited to the party:

and if you ever wanna find your way home: ./drivers/net/ethernet/intel/ice 🧚

that's the whole page, bestie — go forth and reset responsibly. before you go, one lil sign-off: this beauty is dated October 2026, and she ships from the Kernel API Manual source/version. mwah. 💜🎀
