🎀 xe_sriov_pf..._apply_vf_pt(9) 🎀

okay so we're in the Kernel API Manual, and this page is about xe_sriov_pf_provision_apply_vf_pt — yes, the one that changes a VF's preemption timeout. Bestie, it's giving "tiny provisioning glow-up," and I'm obsessed. 💅

Here's the exact signature, no edits, no crumbs:

int xe_sriov_pf_provision_apply_vf_pt (struct xe_device *xe , unsigned
int vfid , u32 pt );

🎀 ARGUMENTS 🎀

• xe — the PF xe_device.
• vfid — the VF identifier.
• pt — the preemption timeout in [us] to set.

💅 DESCRIPTION 💅

Okay so this one changes the VF's preemption timeout (PT) provisioning on all tiles/GTs. All of them. Every tile/GT gets the PT provisioning update, periodt. ✨
