Subject: [PATCH v9 42/84] KVM: introspection: add KVMI_VM_CHECK_COMMAND and KVMI_VM_CHECK_EVENT
Date: Wed, 22 Jul 2020 00:08:40 +0300 [thread overview]
Message-ID: <20200721210922.7646-43-alazar@bitdefender.com> (raw)
In-Reply-To: <20200721210922.7646-1-alazar@bitdefender.com>
These commands are used to check what introspection commands and events
are supported (kernel) and allowed (device manager).
These are alternative methods to KVMI_GET_VERSION in checking if the
introspection supports a specific command/event.
As with the KVMI_GET_VERSION command, these two commands can never be
disallowed by the device manager.

The introspection tool should use this command to identify the features
supported by the kernel side and what messages must be used for event
replies.
