Subject: [PATCH v9 51/84] KVM: introspection: add KVMI_VCPU_GET_INFO
Date: Wed, 22 Jul 2020 00:08:49 +0300 [thread overview]
Message-ID: <20200721210922.7646-52-alazar@bitdefender.com> (raw)
In-Reply-To: <20200721210922.7646-1-alazar@bitdefender.com>
From: Mihai Donțu <mdontu@bitdefender.com>
For now, this command returns the TSC frequency (in HZ) for the specified
vCPU if available (otherwise it returns zero).
