STRUCT XE_HW_ENGINE_CLASS_INTF(9)

💅 struct xe_hw_engine_class_intf(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual entry for struct xe_hw_engine_class_intf — yes the title line elides it all cute as struct xe_hw...e_class_intf(9), that's just the man page being dramatic about long names, don't worry about it 🫶

---

🌸 NAME 🌸

struct xe_hw_engine_class_intf — the per hw engine class struct interface. that's it, that's the whole vibe. it's an interface, it's per-class, it's giving organizational queen 👑

---

✨ SYNOPSIS ✨

struct xe_hw_engine_class_intf {
    struct {
      u32 job_timeout_ms;
      u32 job_timeout_min;
      u32 job_timeout_max;
      u32 timeslice_us;
      u32 timeslice_min;
      u32 timeslice_max;
      u32 preempt_timeout_us;
      u32 preempt_timeout_min;
      u32 preempt_timeout_max;
    } sched_props, defaults;
 };

like. look at her. a nested anonymous struct holding sched_props and defaults, both of them rocking the exact same nine u32 fields. she said "consistency is my love language" fr fr 💖

🎀 Members 🎀

• sched_props — the scheduling properties, live and in person. and also, tucked right into the same line of the struct: defaults: the default scheduling properties 💫
• sched_props.job_timeout_ms — sets the job timeout in ms for the engine ⏱️
• sched_props.job_timeout_min — the min job timeout in ms for the engine
• sched_props.job_timeout_max — the max job timeout in ms for the engine
• sched_props.timeslice_us — the timeslice period in micro-seconds 🍰
• sched_props.timeslice_min — the min timeslice period in micro-seconds
• sched_props.timeslice_max — the max timeslice period in micro-seconds
• sched_props.preempt_timeout_us — the preemption timeout in micro-seconds ⚡
• sched_props.preempt_timeout_min — the min preemption timeout in micro-seconds
• sched_props.preempt_timeout_max — the max preemption timeout in micro-seconds
• defaults — the default scheduling properties. yes she gets her own bullet, she's the blueprint bestie 🫶

ngl the min/max pattern is everywhere here and it's honestly iconic — every knob comes with its own little floor and ceiling. respect the range 💅

🦋 Description 🦋

contains all the hw engine properties per engine class. like, the whole collection. per class. that's the assignment and she ate 🔥

and that's the page!! no cap, you now know everything this struct is about 🧚

sign-off time: this little beauty lives under ./drivers/gpu/drm/xe, dated October 2026, and the footer calls it struct xe_hw...e_class_intf(9) — same elided name as the header, we love a consistent queen 💀✨ bye bestie, go read the kernel 🎀
