From 45b5939e50746b92fd4cb47c02524f79ba8fabe6 Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Fri, 16 Sep 2016 10:27:35 -0400 Subject: kvm: create per-vcpu dirs in debugfs This commit adds the ability for archs to export per-vcpu information via a new per-vcpu dir in the VM's debugfs directory. If kvm_arch_has_vcpu_debugfs() returns true, then KVM will create a vcpu dir for each vCPU in the VM's debugfs directory. Then kvm_arch_create_vcpu_debugfs() is responsible for populating each vcpu directory with arch specific entries. The per-vcpu path in debugfs will look like: /sys/kernel/debug/kvm/29162-10/vcpu0 /sys/kernel/debug/kvm/29162-10/vcpu1 This is all arch specific for now because the only user of this interface (x86) wants to export x86-specific per-vcpu information to user-space.
