ips_irq_handler(9)

💅 ips_irq_handler(9) — like, the whole page, bestie

okay so this is from the Kernel API Manual (yes, that one) and it's about ips_irq_handler — the little function that handles temperature triggers and other IPS events. it's giving "the friend who notices you're about to overheat and turns the fan on" energy, and honestly? iconic. 🥵✨

🌸 NAME 🌸

ips_irq_handler — handle temperature triggers and other IPS events 🎀

like literally what it says on the tin. temp triggers? handled. other IPS events? also handled. she does it all, no cap. 🫶

---

✨ SYNOPSIS ✨

irqreturn_t ips_irq_handler (int irq , void *arg );

that's it. two args, one return type, zero drama. main character function signature fr fr. 💅

---

🦋 ARGUMENTS 🦋

• irq — the irq number. that's the whole description. it's just. the irq number. 💀
• arg — unused. she is literally not beating the "unused" allegations. sitting there being void * and doing absolutely nothing. we respect her anyway 🙈

---

🔥 DESCRIPTION 🔥

okay so here's the tea: this function handles temperature limit trigger events, and it generally does that by lowering the clamps. think of clamps as the vibe ceiling — she's bringing it down when things get too warm. 😌

and if we're at a critical limit? she doesn't panic, she doesn't spiral, she just clamps back to the lowest possible value to prevent emergency shutdown. like, that's self-care. that's damage control. that's protecting the whole system from a full-on meltdown. 🌈

not me being the last line of defense between you and an emergency shutdown 🚨💀

---

👑 RETURN 👑

IRQ_NONE or IRQ_HANDLED

two options. no in-between. she either handled it or she didn't, and either way she's telling you honestly. communication queen. ⭐

first up, the kernel file that started it all: ./drivers/platform/x86/intel_ips.c — that's the source, bestie, go read it, it's right there 👀

and now the whole group chat, in the exact order they're listed:

ips_cpu_busy(9), ips_cpu_raise(9), ips_cpu_lower(9), do_enable_cpu_turbo(9), ips_enable_cpu_turbo(9), do_disable_cpu_turbo(9), ips_disable_cpu_turbo(9), ips_gpu_busy(9), ips_gpu_raise(9), ips_gpu_lower(9), ips_enable_gpu_turbo(9), ips_disable_gpu_turbo(9), mcp_exceeded(9), cpu_exceeded(9), mch_exceeded(9), verify_limits(9), update_turbo_limits(9), ips_adjust(9), ips_monitor(9), ips_detect_cpu(9), ips_get_i915_syms(9)

that's twenty-one cross-references and yes, she knows every single one of them by name. iykyk 💜
