Subject: [PATCH v9 56/84] KVM: introspection: add KVMI_VCPU_GET_REGISTERS
Date: Wed, 22 Jul 2020 00:08:54 +0300 [thread overview]
Message-ID: <20200721210922.7646-57-alazar@bitdefender.com> (raw)
In-Reply-To: <20200721210922.7646-1-alazar@bitdefender.com>
From: Mihai Donțu <mdontu@bitdefender.com>
This command is used to get kvm_regs and kvm_sregs structures,
plus a list of struct kvm_msrs from a specific vCPU.
While the kvm_regs and kvm_sregs structures are included with every
event, this command allows reading any MSR and can be used as a quick
way to read the state of any vCPU.
