vtime_reset(9)

okay so bestie, welcome to the vtime_reset(9) page from the Kernel API Manual ✨ this one is short and sweet but she still ate 💅

🎀 NAME 🎀

vtime_reset — fast forward vtime entry clocks. literally that's the name, no cap.

✨ SYNOPSIS ✨

void vtime_reset (void );

🫶 ARGUMENTS 🫶

void        no arguments

hi bestie, void means no arguments here — zero, none, the void of it all 🫶. you call it with nothing and you pass it nothing.

💖 DESCRIPTION 💖

okay so the tea: vtime_reset is called from dynticks idle IRQ entry to fast-forward the clocks to current time so that the IRQ time is still accounted by vtime while nohz cputime is paused. that's the whole description, and honestly she's iconic for it 👑.

🌈 SEE ALSO 🌈

• Kernel file ./arch/powerpc/kernel/time.c

go give these a look, bestie — they're right there in the same kernel-file / dyntick-vtime orbit 💫

tiny page, big accounting energy 💀 — and that's it, fr fr.
