Subject: [RFC PATCH v6 08/92] kvm: introspection: add KVMI_CHECK_COMMAND and KVMI_CHECK_EVENT
Date: Fri, 9 Aug 2019 18:59:23 +0300 [thread overview]
Message-ID: <20190809160047.8319-9-alazar@bitdefender.com> (raw)
In-Reply-To: <20190809160047.8319-1-alazar@bitdefender.com>
These commands can be used by the introspection tool to check what
introspection commands and events are supported (by KVMi) and allowed
(by userspace/QEMU).
The introspection tool will get one of the following error codes:
* -KVM_EOPNOTSUPP (unsupported command/event)
* -KVM_PERM (disallowed command/event)
* -KVM_EINVAL (the padding space, used for future extensions,
is not zero)
* 0 (the command/event is supported and allowed)
These commands can be seen as an alternative method to KVMI_GET_VERSION
in checking if the introspection supports a specific command/event.
As with the KVMI_GET_VERSION command, these commands can never be
disallowed by userspace/QEMU.
