💅 xe_sriov_pf_provision_apply_vf_eq — a lil Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual page for xe_sriov_pf..._apply_vf_eq(9), and no cap this one is a whole vibe: it's the function that changes a VF's execution quantum. yes ma'am, we're doing SR-IOV provisioning today 🎀

🌸 NAME 🌸

xe_sriov_pf_provision_apply_vf_eq — Change VF's execution quantum.

that's it. that's the whole name. iconic, brief, to the point 💅

✨ SYNOPSIS ✨

int xe_sriov_pf_provision_apply_vf_eq (struct xe_device *xe , unsigned
int vfid , u32 eq );

she takes three things and returns an int, periodt 🫶

🦋 ARGUMENTS 🦋

  • xe — the PF xe_device. like, the whole physical function device, bestie 💖
  • vfid — the VF identifier. which virtual function are we talking about, iykyk 🌈
  • eq — execution quantum in [ms] to set. milliseconds, okurrr ⏱️

🔥 DESCRIPTION 🔥

Change VF's execution quantum (EQ) provisioning on all tiles/GTs. literally all of them, she does not do half measures 💀
