kvm_mips_count_disable(9)
π kvm_mips_count_disable(9) β the Kernel API Manual glow-up
okay so bestie, welcome to the Kernel API Manual entry for kvm_mips_count_disable, and honestly? it's a little baddie of a function. let's get into it π
β¨ NAME β¨
kvm_mips_count_disable β literally just Disable count. that's the whole vibe. periodt. π
πΈ SYNOPSIS πΈ
ktime_t kvm_mips_count_disable (struct kvm_vcpu *vcpu );
like, that's the signature, copy it exactly, no cap. β¨
π¦ ARGUMENTS π¦
vcpuβ the Virtual CPU. that's it, that's the whole argument. she just wants her vcpu π«Ά
π DESCRIPTION π
okay so what she does: she disables the CP0_Count timer π₯.
and here's the tea on timing β a timer interrupt that lands on or before the final stop time will be handled, but anything after it? nope, not happening, she's off the clock π.
also, lowkey important: this function assumes CP0_Count was previously enabled but that now either Guest.CP0_Cause.DC or count_ctl.DC has been set (i.e. count disabled). so like, know that going in, bestie π.
β RETURN β
she returns the time that the timer was stopped π. iconic behavior honestly.
π SEE ALSO π
the Kernel file is ./arch/mips/kvm/emulate.c β and here's the whole friend group, all of them, don't skip a single one π:

ngl, if you're messing with the count timer, read the whole squad above before you ship anything π§
and that's the page!! mwah π β this gem lives in the kernel source tree at ./arch/mips/kvm, dated October 2026, and it's kvm_mips_count_disable(9) all day every day. slay, go stop some timers responsibly ππ
