When calling perf_event_create_kernel_counter to create perf_event,
assign a overflow handler. Then when perf event overflows, set
irq_pending and call kvm_vcpu_kick() to sync the interrupt.

Hi Shannon,
[auto build test ERROR on kvm/linux-next -- if it's inappropriate base, please
suggest rules for selecting the more suitable base]
url:
https://github.com/0day-ci/linux/commits/Shannon-Zhao/KVM-ARM64-Add-guest-PMU-support/20151030-143148
config: arm-axm55xx_defconfig (attached
Hi,
Thanks for your test:)
It fails because there is no arch/arm/include/asm/pmu.h while
arch/arm64/include/asm/pmu.h exists. Will fix this at next version.
