From 0d0ae656b71155ccc0be9388beef77a1f7e7558e Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 30 Mar 2023 18:47:41 +0100 Subject: KVM: arm64: timers: Use a per-vcpu, per-timer accumulator for fractional ns Instead of accumulating the fractional ns value generated every time we compute a ns delta in a global variable, use a per-vcpu, per-timer variable. This keeps the fractional ns local to the timer instead of contributing to any odd, unrelated timer.
