✨ xe_gt_sriov_pf_policy_init(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 — yes, that's the whole vibe, we're in the Kernel API Manual today and this page is literally called xe_gt_sriov_pf_policy_init(9). Buckle up, it's a short one and honestly kind of iconic for it 🎀

🌸 NAME 🌸

xe_gt_sriov_pf_policy_init — Initializes the SW state of the PF policies. that's it. that's the whole job. slay 💖

ngl the name is a mouthful, but it's giving exactly what it says on the tin: it's the init for the PF policy SW state, on a gt. iykyk 🦋

⭐ SYNOPSIS ⭐

void xe_gt_sriov_pf_policy_init (struct xe_gt *gt );

like, no return value, no nonsense. it takes one gt and it goes ✨ void ✨ — it's giving "I do my thing and I don't report back" main character energy 👑

🧚 ARGUMENTS 🧚

  • gt — the xe_gt 🫶 (yes queen, that's the argument. that's the whole argument. we love a one-parameter function fr fr)

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this function can only be called on PF. not PF-adjacent, not "if you feel like it", PF only. periodt 💀

and the other thing? this function does not touch the HW at all — zero hardware contact, it's purely vibing in software-land 🦋 but! and this is the important part bestie — it must be called after the engines have been initialized. so like, don't come at it early, it needs the engines already set up or it's gonna be awkward 😭

⚠️ tiny but mighty caveats: PF only, no HW interaction, call it after engine init. no cap, those three things are the entire personality of this function 💅

👑 SEE ALSO 👑

first up, the source file where all this lives — go look, she's right there:

  • Kernel file ./drivers/gpu/drm/xe/xe_gt_sriov_pf_policy.c

and then the whole friend group 🫶 — literally all the related calls, no gatekeeping:

like, the whole setter/getter cinematic universe 🌈 go read them, they're all right there, I'm not doing your homework for you bestie 😌

and that's the page!! mwah 💋 this gem comes to you from ./drivers/gpu/drm/xe, dated October 2026 — so mark your calendars, screenshot it, frame it, whatever 🎀 bye bestie, go init some PF policy SW state responsibly 🦋💜
