[PATCH 0/4] RISC-V KVM PMU fix and selftest improvement
From: Atish Patra
Date: Wed Feb 26 2025 - 15:25:22 EST
This series adds a fix for KVM PMU code and improves the pmu selftest
by allowing generating precise number of interrupts. It also provided
another additional option to the overflow test that allows user to
generate custom number of LCOFI interrupts.
