kvm_mips_resume_hrtimer(9)

okay so bestie, this is the kvm_mips_resume_hrtimer(9) page from the Kernel API Manual, and it’s literally about resuming an hrtimer and updating its expiry. 💖

✨ NAME ✨

kvm_mips_resume_hrtimer — Resume hrtimer, updating expiry. That’s the whole main-character job, no cap. 🎀

🎀 SYNOPSIS 🎀

void kvm_mips_resume_hrtimer (struct kvm_vcpu *vcpu , ktime_t now , u32
       count );

💅 ARGUMENTS 💅

• vcpu — Virtual CPU. literally the vCPU we’re resuming for.
• now — ktime at point of resume.
• count — CP0_Count at point of resume.

🦋 DESCRIPTION 🦋

Resumes the timer and updates the timer expiry based on now and count. This can be used in conjunction with kvm_mips_freeze_timer when timer parameters need to be changed. It’s giving freeze-and-resume teamwork. ✨

It is guaranteed that a timer interrupt immediately after resume will be handled, but not if CP_Compare is exactly at count. That case is already handled by kvm_mips_freeze_timer. So yeah — tiny exception, very important. 💀

Assumes !kvm_mips_count_disabled(vcpu) (guest CP0_Count timer is running). Keep that assumption close, bestie. 🫶
