👑 struct xe_hwmon_fan_info(9) 👑

okay so bestie, welcome to the Kernel API Manual ✨ and today's main character is struct xe_hwmon_fan_info(9) — the tiniest little glow-up struct whose whole entire job is remembering what your fan said last time. no cap, that's it, that's the vibe 🫶

• time_prev — the previous timestamp ⏰ so we know when that last reading happened, iykyk

• struct xe_hwmon(9)

go read those too, they're the extended universe 🌈
