💅 xe_gt_sriov_pf_config_set_preempt_timeout_locked 💅

okay so bestie, welcome to the Kernel API Manual</> (section 9, we're fancy here) — this is the page for xe_gt_sriov_pf_config_set_preempt_timeout_locked, and yes the page title really does get truncated like that in the header. iconic little ellipsis moment, no notes 💀

✨ NAME ✨

xe_gt_sriov_pf_config_set_preempt_timeout_locked — literally just here to configure the PF/VF preemption timeout. that's it, that's the whole gig 🎀

🦋 SYNOPSIS 🦋

int xe_gt_sriov_pf_config_set_preempt_timeout_locked (struct xe_gt *gt ,
unsigned int vfid , u32 preempt_timeout );

🌸 ARGUMENTS 🌸

  • gt — the xe_gt 🫶 that's your graphics tile bestie, the whole reason we're here
  • vfid — the PF or VF identifier, like the little name tag telling us which function we're configuring
  • preempt_timeout — the preemption timeout you're requesting, measured in microseconds ⏱️ and heads up: 0 means infinity, which is a whole vibe ngl

🔥 DESCRIPTION 🔥

okay so listen 👀 — this function can only be called on the PF, and only with the master mutex held. that's a hard requirement, not a suggestion, so don't come at it sideways.

the way it works is it'll log the provisioned value — or, if things go sideways, it logs the error instead. either way you get receipts 📝✨

⚠️ lowkey important: PF only, and the master mutex must be held. this is not a "try it and see" situation bestie 😭

⭐ RETURN ⭐

0 on success — slay 💖 — or a negative error code on failure. that's the whole dealio.
