💅 xe_gt_sriov_pf_init_hw(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function with a big job: xe_gt_sriov_pf_init_hw. say it with me now — ex-ee underscore gee-tee underscore ess-arr-eye-oh-vee underscore pee-eff underscore init underscore aitch-double-you 🎀 iconic name, no notes.

🌸 NAME 🌸

xe_gt_sriov_pf_init_hw — Initialize SR-IOV hardware support. that's it, that's the whole vibe 🫶

✨ SYNOPSIS ✨

so the whole signature is literally one line, slay:

void xe_gt_sriov_pf_init_hw (struct xe_gt *gt );

note the void — it returns nothing, it just does the thing and leaves. main character energy fr 💅

🦋 ARGUMENTS 🦋

  • gt — the xe_gt to initialize 🧚 that's your graphics tile / GT struct, and yes, it's the one getting the glow-up here.

👑 DESCRIPTION 👑

okay so here's the tea ☕ — on some platforms (not all of them, don't @ me), the PF — that's the Physical Function, the big boss of the SR-IOV situation — has to explicitly enable the VF's access to the GGTT. like, it's not automatic, nobody's doing it for you, the PF literally has to go turn that door handle itself 🔑

the VFs don't get a vibe check on the GGTT unless the PF hands them one. periodt. 👑

heads up bestie: this is the hardware init step 💀 don't confuse it with the early init or the regular init — those are different functions, they're in SEE ALSO, we'll get there.
