💅 xe_gt_sriov_...antum_locked(9)

okay bestie so this is from the Kernel API Manual (yes, the whole manual, we're fancy now) and the page header is literally xe_gt_sriov_...antum_locked(9) — yes it's abbreviated, yes it's giving "we ran out of column inches," no we don't talk about it 💀

✨ NAME ✨

xe_gt_sriov_pf_config_bulk_set_exec_quantum_locked — configures the EQ for the PF and all the VFs. bulk energy, group-chat energy, one call and everybody gets the memo 🫶

🎀 SYNOPSIS 🎀

int xe_gt_sriov_pf_config_bulk_set_exec_quantum_locked (struct xe_gt *gt
, u32 exec_quantum );

🌸 ARGUMENTS 🌸

  • gt — the xe_gt you're configuring. that's the one, that's the target 🎯
  • exec_quantum — the execution quantum you're requesting, in milliseconds. and listen: 0 is infinity ⭐ no cap, zero means forever, that's just how it is.

🦋 DESCRIPTION 🦋

This function can only be called on the PF with the master mutex held. like, held-held. if you don't have the master mutex, this is not your moment, bestie 🙈 not a vibe, not a slay, just don't.

fr fr — PF only, master mutex held. that's the whole vibe check for this one.

💜 RETURN 💜

  • 0 on success 🎉 slay
  • a negative error code on failure 😭 it's giving "not today"

okay that's the page!! sign-off time 🫶 this whole thing lives in ./drivers/gpu/drm/xe and it's dated October 2026, and the footer still says xe_gt_sriov_...antum_locked(9) because of course it does. go configure those quantums bestie, ily, drink water 💖✨🌸
