ice_reset_vf(9)

💅 ice_reset_vf(9) — the Kernel API Manual, bestie edition 🎀

okay so this is ice_reset_vf from the Kernel API Manual, and it's literally the "hit the reset button on one VF" function. Let's get into it ✨

---

🌸 NAME 🌸

ice_reset_vf — Reset a particular VF

yeah that's it, that's the whole vibe check: one specific VF gets reset, nobody else 💅

---

⭐ SYNOPSIS ⭐

int ice_reset_vf (struct ice_vf *vf , u32 flags );

so you hand it a vf and some flags, and it gives you back an int. simple as 🫶

---

💖 ARGUMENTS 💖

• vf — pointer to the VF structure. like, the actual VF you're about to reset. main character energy 👑
• flags — flags that control the behavior of the reset. these are the little switches that change how the reset goes down ✨

---

🔥 DESCRIPTION 🔥

okay so here's the flag lore, and honestly you need all three bestie:

Flags:

• ICE_VF_RESET_VFLR — Indicates a reset is due to VFLR event. so like, this reset happened because of a VFLR thing, not because someone just felt like it 💀
• ICE_VF_RESET_NOTIFY — Send VF a notification prior to reset. polite queen behavior honestly, warn them first 🎀
• ICE_VF_RESET_LOCK — Acquire VF cfg_lock before resetting. grab the lock first, no cap 🔒

Return values, listen up:

• Returns 0 if the VF is currently in reset
• Returns 0 if resets are disabled
• Returns 0 if the VF resets successfully
• Returns an error code if the VF fails to rebuild 😭

fr fr though — a 0 here does NOT only mean "yaaay success". it also means the VF was already mid-reset, or that resets are just turned off entirely. three different situations, same 0. iykyk 🙈

🦋 SEE ALSO 🦋

the kernel file lives right here, go look at it if you want the tea:

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