kvm_mips_cou...isable_cause(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

Okay bestie, so this page is from the Kernel API Manual, and it's all about kvm_mips_count_disable_cause — which, as the name lowkey screams, disables the count using CP0_Cause.DC. That's the whole vibe. Periodt.

✨ SYNOPSIS ✨

void kvm_mips_count_disable_cause (struct kvm_vcpu *vcpu );

🎀 ARGUMENTS 🎀

  • vcpu — the Virtual CPU. That's it, that's the whole argument. Your main character struct. 👑

🦋 DESCRIPTION 🦋

So what does this thing actually do? It disables the CP0_Count timer and sets CP0_Cause.DC. Two-for-one slay. 💅

Here's the tea on timing, because it genuinely matters: a timer interrupt that lands on or before the final stop time will be handled — but only if the timer isn't already disabled by count_ctl.DC. After that? Nope. Not happening. 🙈

⚠️ Heads up, bestie: this function assumes CP0_Cause.DC is clear (like, count is enabled). That's the precondition, no cap. Don't come at it with DC already set and expect good things. 😭

🌸 SEE ALSO 🌸

The kernel file in question is ./arch/mips/kvm/emulate.c. And ngl, this function has a whole squad — look at this friend group:

Like, the whole MIPS KVM count-timer cinematic universe. Obsessed. 🔥

Okay that's the whole page, bestie — go disable some counts responsibly 💜
