💅 xe_sriov_pf_service_reset_vf 💅

okay so real talk, this one's from the Kernel API Manual bestie, and it's a whole function page about resetting a VF connection. yes it's niche, no i'm not apologizing, it's iconic actually 💖

✨ NAME ✨

xe_sriov_pf_service_reset_vf — Reset a connection with the VF.

like, the whole vibe of this function is "we're starting over, no hard feelings" 🫶

---

🌸 SYNOPSIS 🌸

void xe_sriov_pf_service_reset_vf (struct xe_device *xe , unsigned int
vfid );

not me giving you the exact signature character for character, because i love you and also because it matters 😌

---

💜 ARGUMENTS 💜

• xe — the xe_device. that's the device, the main character of this whole story ngl 👑
• vfid — the VF identifier. which VF are we resetting, bestie? this one. this number right here ✨

🦋 DESCRIPTION 🦋

so here's the tea: this resets a VF driver negotiated VF/PF ABI version. yes that's a mouthful, no i won't shorten it, it's giving "technical precision" and we respect it 🎀

after that point — and this is the important part, like highkey important — the VF driver will have to perform a new version handshake to continue use of the PF services again. so basically: reset happened, vibe check done, and now they gotta re-introduce themselves properly before they can use the PF services again. no skipping the handshake, no cap 🙈

⚠️ heads up bestie: this function can only be called on PF. that's a hard limit, not a suggestion. don't try it anywhere else, fr fr 💀
