β¨ kvm_mips_count_time(9) β¨
okay so this is from the Kernel API Manual, section 9, and bestie it's a little one but it's lowkey important π
πΈ NAME πΈ
kvm_mips_count_time β get effective current time, no cap β°
π¦ SYNOPSIS π¦
ktime_t kvm_mips_count_time (struct kvm_vcpu *vcpu );
π ARGUMENTS π
vcpuβ the virtual CPU. that's it, that's the whole argument π«Ά
π DESCRIPTION π
okay so the way this works: it gets you the effective monotonic ktime. and honestly? most of the time it's literally just a straightforward ktime_get. like, nothing dramatic, nothing extra, just vibing π
but β and this is the part you gotta clock β when the master disable bit is set in count_ctl, it is not a plain ktime_get anymore. in that case it's count_resume, i.e. the time that the count was disabled. so it's giving "rewind to the moment we paused" energy π the count was frozen, and this hands you back that exact timestamp. iconic behaviour, fr fr.
β RETURN β
effective monotonic ktime for CP0_Count π
