📦 version 7.3.1, in nixpkgs unstable

💾 xe_gt_sriov_pf_migration_mmio_save(9) — bestie edition ✨

okay so this is from the Kernel API Manual (the xe_gt_sriov_...on_mmio_save(9) page, yes the title got abbreviated, she's mysterious like that 💅) and honestly? she's short, she's sweet, and she does exactly one thing. let's get into it 🎀

🌸 NAME 🌸

xe_gt_sriov_pf_migration_mmio_save — literally just "Save VF MMIO migration data." that's the whole personality. no notes. iconic. 🫶

✨ SYNOPSIS ✨

int xe_gt_sriov_pf_migration_mmio_save (struct xe_gt *gt , unsigned int
vfid );

like yes that's a struct xe_gt * and an unsigned int and she returns an int, we love a simple signature, no cap 💖

🦋 ARGUMENTS 🦋

  • gt — the xe_gt. that's it. that's the description. she's a struct xe_gt pointer and she knows it 👑
  • vfid — the VF identifier. and heads up bestie: it can't be 0. like, at all. zero is not invited to this party 🙈

💜 DESCRIPTION 💜

so the vibe check here is very specific: this function is for PF only. PF, not VF. don't come at her with VF business, she will not be doing that 🫠

that's genuinely the entire description. she's a one-line icon and she ate. ⭐

🔥 RETURN 🔥

  • 0 — success, slay, we're so back 🌈
  • negative error code — failure, we're so not back 😭

🧚 SEE ALSO 🧚

okay this is the part where she name-drops literally her entire friend group, and there are a LOT of them, so buckle up buttercup 🍓

first, the source file where she lives (iykyk):

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

and now the whole squad, in order, exactly as listed, no gatekeeping:

not a single one skipped bestie, we do NOT do that here 💀

<ahem> and that's the whole page!! 💖

sign-off time because the footer deserves her moment too: this little gem comes from the source dir ./drivers/gpu/drm/xe, dated October 2026, and she's filed under xe_gt_sriov_...on_mmio_save(9) — same truncated queen energy as the header, we stan a consistent brand 🎀✨

mwah, go save those MMIOs, ily 🫶💜
