💅 xe_sriov_pf_provision_bulk_apply_pt 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy here — and today's main character is xe_sriov_pf_provision_bulk_apply_pt. literally the whole vibe is "set the preemption timeout everywhere at once." no cap.

✨ NAME ✨

xe_sriov_pf_provision_bulk_apply_pt — Change preemption timeout for all VFs and PF.

like, all of them. bulk mode. group chat blast. 🫶

🌸 SYNOPSIS 🌸

int xe_sriov_pf_provision_bulk_apply_pt (struct xe_device *xe , u32 pt
);

that's the whole signature bestie, copy it exactly, don't be weird about the spacing 😭

🎀 ARGUMENTS 🎀

  • xe — the PF xe_device. the physical function one. the main character device fr.
  • pt — preemption timeout in [us] to set. microseconds, periodt. ⏱️

🦋 DESCRIPTION 🦋

Change preemption timeout (PT) provisioning on all tiles/GTs.

that's it, that's the whole bit — one call, every tile/GT gets the new PT. it's giving efficiency. it's giving "I'm not doing this in a for-loop myself." 👑

⚠️ real talk though: this function can only be called on PF. like, only. PF only. if you're a VF trying to call this, no you aren't, go home. 🚫

⭐ RETURN ⭐

  • 0 on success 💖
  • a negative error code on failure 💀

that's the whole return contract, sweetie. zero means slay, negative means not slay.

like an entire ensemble cast, honestly. the apply/query/bulk trio for eq, pt, priority AND vram — that's range. 🧚💜
