Subject: [PATCH v3 0/7] hyperv: VMBus implementation
Date: Tue, 7 Apr 2020 08:51:49 +0300 [thread overview]
Message-ID: <20200407055156.137249-1-arilou@gmail.com> (raw)
This is a rebase of the old patchset from Roman for HyperV VMBus
implementation.
How to use:
-device vmbus-bridge
Later on new paravirtualized devices can be implemented on top of it
(Network/SCSI/etc.)
VMBus is a collection of technologies. At its lowest layer, it's a message
passing and signaling mechanism, allowing efficient passing of messages to and
from guest VMs. A layer higher, it's a mechanism for defining channels of
communication, where each channel is tagged with a type (which implies a
protocol) and a instance ID. A layer higher than that, it's a bus driver,
serving as the basis of device enumeration within a VM, where a channel can
optionally be exposed as a paravirtual device. When a server-side (paravirtual
back-end) component wishes to offer a channel to a guest VM, it does so by
specifying a channel type, a mode, and an instance ID. VMBus then exposes this
in the guest.
More information about VMBus can be found in the file
vmbuskernelmodeclientlibapi.h in Microsoft's WDK.
v3:
Fixed an error asan
v2:

vmbus: vmbus implementation
i386:pc: whitelist dynamic vmbus-bridge
i386: Hyper-V VMBus ACPI DSDT entry
