xe_hw_engin...out_in_range(9)

✨ NAME ✨

xe_hw_engine_timeout_in_range — bestie, it's literally just a lil helper that checks if a timeout is in range 💖

So this is from the Kernel API Manual, and the star of the show is xe_hw_engine_timeout_in_range(9). That's the whole vibe, okay?

---

🌸 SYNOPSIS 🌸

bool xe_hw_engine_timeout_in_range (u64 timeout , u64 min , u64 max );

Like, it takes three u64s and hands you back a bool. Clean. Simple. Iconic. 🎀

---

🦋 ARGUMENTS 🦋

• timeout — the timeout you're validating, aka the thing we're putting under the microscope 🔍
• min — the min value of the valid range, the floor, the lower bound, the "no going below this" line ⬇️
• max — the max value of the valid range, the ceiling, the upper bound, the "that's far enough" line ⬆️

---

💅 DESCRIPTION 💅

Okay so picture this: this helper exists to validate whether timeout is sitting all cozy inside the min–max range of the HW engine scheduler. That's it. That's the job. It checks the range, it slays, it goes home. No cap. ✨

---

🔥 RETURN 🔥

• Returns false for failure 😭
• Returns true for success 👑

So like, a vibe check result, essentially. true means you're in range and thriving; false means nope.
