[PATCH v9 00/18] HSM driver for ACRN hypervisor

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

ACRN is a Type 1 reference hypervisor stack, running directly on the bare-metal
hardware, and is suitable for a variety of IoT and embedded device solutions.

ACRN implements a hybrid VMM architecture, using a privileged Service VM. The
Service VM manages the system resources (CPU, memory, etc.) and I/O devices of
User VMs. Multiple User VMs are supported, with each of them running Linux,
Android OS or Windows. Both Service VM and User VMs are guest VM.

Below figure shows the architecture.

There is only one Service VM which could run Linux as OS.

In a typical case, the Service VM will be auto started when ACRN Hypervisor is
booted. Then the ACRN userspace (an application running in Service VM) could be
used to start/stop User VMs by communicating with ACRN Hypervisor Service
Module (HSM).

ACRN Hypervisor Service Module (HSM) is a middle layer that allows the ACRN
userspace and Service VM OS kernel to communicate with ACRN Hypervisor
and manage different User VMs. This middle layer provides the following
functionalities,
  - Issues hypercalls to the hypervisor to manage User VMs:
      * VM/vCPU management
      * Memory management
      * Device passthrough
      * Interrupts injection
  - I/O requests handling from User VMs.
  - Exports ioctl through HSM char device.
  - Exports function calls for other kernel modules

ACRN is focused on embedded system. So it doesn't support some features.
E.g.,
  - ACRN doesn't support VM migration.
  - ACRN doesn't support vCPU migration.

This patch set adds the HSM to the Linux kernel.
I also added a simple example to launch a small guest (with several instructions
as payload) on ACRN with demonstration ioctl usage.

The basic ARCN support was merged to upstream already.

+ACRN Hypervisor Introduction
+============================
+
+The ACRN Hypervisor is a Type 1 hypervisor, running directly on bare-metal
+hardware. It has a privileged management VM, called Service VM, to manage User
+VMs and do I/O emulation.
+
+ACRN userspace is an application running in the Service VM that emulates
+devices for a User VM based on command line configurations. ACRN Hypervisor
+Service Module (HSM) is a kernel module in the Service VM which provides
+hypervisor services to the ACRN userspace.
+
+Below figure shows the architecture.

+
+ACRN userspace allocates memory for the User VM, configures and initializes the
+devices used by the User VM, loads the virtual bootloader, initializes the
+virtual CPU state and handles I/O request accesses from the User VM. It uses
+ioctls to communicate with the HSM. HSM implements hypervisor services by
+interacting with the ACRN Hypervisor via hypercalls. HSM exports a char device
+interface (/dev/acrn_hsm) to userspace.
+
+The ACRN hypervisor is open for contribution from anyone. The source repo is
+available at https://github.com/projectacrn/acrn-hypervisor.

+I/O request handling
+====================
+
+An I/O request of a User VM, which is constructed by the hypervisor, is
+distributed by the ACRN Hypervisor Service Module to an I/O client
+corresponding to the address range of the I/O request. Details of I/O request
+handling are described in the following sections.
+
+1. I/O request
+--------------
+
+For each User VM, there is a shared 4-KByte memory region used for I/O requests
+communication between the hypervisor and Service VM. An I/O request is a
+256-byte structure buffer, which is 'struct acrn_io_request', that is filled by
+an I/O handler of the hypervisor when a trapped I/O access happens in a User
+VM. ACRN userspace in the Service VM first allocates a 4-KByte page and passes
+the GPA (Guest Physical Address) of the buffer to the hypervisor. The buffer is
+used as an array of 16 I/O request slots with each I/O request slot being 256
+bytes. This array is indexed by vCPU ID.
+
+2. I/O clients
+--------------
+
+An I/O client is responsible for handling User VM I/O requests whose accessed
+GPA falls in a certain range. Multiple I/O clients can be associated with each
+User VM. There is a special client associated with each User VM, called the
+default client, that handles all I/O requests that do not fit into the range of
+any other clients. The ACRN userspace acts as the default client for each User
+VM.
+
+Below illustration shows the relationship between I/O requests shared buffer,
+I/O requests and I/O clients.

+     |  +-------------+                                     |
+     +------------------------------------------------------+
+
+3. I/O request state transition
+-------------------------------
+
+The state transitions of an ACRN I/O request are as follows.
+
+::
+
+   FREE -> PENDING -> PROCESSING -> COMPLETE -> FREE -> ...
+
+- FREE: this I/O request slot is empty
+- PENDING: a valid I/O request is pending in this slot
+- PROCESSING: the I/O request is being processed
+- COMPLETE: the I/O request has been processed
+
+An I/O request in COMPLETE or FREE state is owned by the hypervisor. HSM and
+ACRN userspace are in charge of processing the others.
+
+4. Processing flow of I/O requests
+----------------------------------
+
+a. The I/O handler of the hypervisor will fill an I/O request with PENDING
+   state when a trapped I/O access happens in a User VM.
+b. The hypervisor makes an upcall, which is a notification interrupt, to
+   the Service VM.
+c. The upcall handler schedules a worker to dispatch I/O requests.
+d. The worker looks for the PENDING I/O requests, assigns them to different
+   registered clients based on the address of the I/O accesses, updates
+   their state to PROCESSING, and notifies the corresponding client to handle.
+e. The notified client handles the assigned I/O requests.
+f. The HSM updates I/O requests states to COMPLETE and notifies the hypervisor
+   of the completion via hypercalls.

[PATCH v9 02/18] x86/acrn: Introduce acrn_{setup, remove}_intr_handler()

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

The ACRN Hypervisor builds an I/O request when a trapped I/O access
happens in User VM. Then, ACRN Hypervisor issues an upcall by sending
a notification interrupt to the Service VM. HSM in the Service VM needs
to hook the notification interrupt to handle I/O requests.

Notification interrupts from ACRN Hypervisor are already supported and
a, currently uninitialized, callback called.

Export two APIs for HSM to setup/remove its callback.

[PATCH v9 03/18] x86/acrn: Introduce acrn_cpuid_base() and hypervisor feature bits

[shuo.a.liu]

From: Yin Fengwei <fengwei.yin@intel.com>

ACRN Hypervisor reports hypervisor features via CPUID leaf 0x40000001
which is similar to KVM. A VM can check if it's the privileged VM using
the feature bits. The Service VM is the only privileged VM by design.

[PATCH v9 04/18] x86/acrn: Introduce hypercall interfaces

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

The Service VM communicates with the hypervisor via conventional
hypercalls. VMCALL instruction is used to make the hypercalls.

ACRN hypercall ABI:
  * Hypercall number is in R8 register.
  * Up to 2 parameters are in RDI and RSI registers.
  * Return value is in RAX register.

Introduce the ACRN hypercall interfaces. Because GCC doesn't support R8
register as direct register constraints, use supported constraint as
input with a explicit MOV to R8 in beginning of asm.

[PATCH v9 05/18] virt: acrn: Introduce ACRN HSM basic driver

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

ACRN Hypervisor Service Module (HSM) is a kernel module in Service VM
which communicates with ACRN userspace through ioctls and talks to ACRN
Hypervisor through hypercalls.

Add a basic HSM driver which allows Service VM userspace to communicate
with ACRN. The following patches will add more ioctls, guest VM memory
mapping caching, I/O request processing, ioeventfd and irqfd into this
module. HSM exports a char device interface (/dev/acrn_hsm) to userspace.

[PATCH v9 06/18] virt: acrn: Introduce VM management interfaces

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

The VM management interfaces expose several VM operations to ACRN
userspace via ioctls. For example, creating VM, starting VM, destroying
VM and so on.

The ACRN Hypervisor needs to exchange data with the ACRN userspace
during the VM operations. HSM provides VM operation ioctls to the ACRN
userspace and communicates with the ACRN Hypervisor for VM operations
via hypercalls.

HSM maintains a list of User VM. Each User VM will be bound to an
existing file descriptor of /dev/acrn_hsm. The User VM will be
destroyed when the file descriptor is closed.

[PATCH v9 07/18] virt: acrn: Introduce an ioctl to set vCPU registers state

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

A virtual CPU of User VM has different context due to the different
registers state. ACRN userspace needs to set the virtual CPU
registers state (e.g. giving a initial registers state to a virtual
BSP of a User VM).

HSM provides an ioctl ACRN_IOCTL_SET_VCPU_REGS to do the virtual CPU
registers state setting. The ioctl passes the registers state from ACRN
userspace to the hypervisor directly.

[PATCH v9 08/18] virt: acrn: Introduce EPT mapping management

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

The HSM provides hypervisor services to the ACRN userspace. While
launching a User VM, ACRN userspace needs to allocate memory and request
the ACRN Hypervisor to set up the EPT mapping for the VM.

A mapping cache is introduced for accelerating the translation between
the Service VM kernel virtual address and User VM physical address.

From the perspective of the hypervisor, the types of GPA of User VM can be
listed as following:
   1) RAM region, which is used by User VM as system ram.
   2) MMIO region, which is recognized by User VM as MMIO. MMIO region is
      used to be utilized for devices emulation.

Generally, User VM RAM regions mapping is set up before VM started and
is released in the User VM destruction. MMIO regions mapping may be set
and unset dynamically during User VM running.

To achieve this, ioctls ACRN_IOCTL_SET_MEMSEG and ACRN_IOCTL_UNSET_MEMSEG
are introduced in HSM.

[PATCH v9 09/18] virt: acrn: Introduce I/O request management

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

An I/O request of a User VM, which is constructed by the hypervisor, is
distributed by the ACRN Hypervisor Service Module to an I/O client
corresponding to the address range of the I/O request.

For each User VM, there is a shared 4-KByte memory region used for I/O
requests communication between the hypervisor and Service VM. An I/O
request is a 256-byte structure buffer, which is 'struct
acrn_io_request', that is filled by an I/O handler of the hypervisor
when a trapped I/O access happens in a User VM. ACRN userspace in the
Service VM first allocates a 4-KByte page and passes the GPA (Guest
Physical Address) of the buffer to the hypervisor. The buffer is used as
an array of 16 I/O request slots with each I/O request slot being 256
bytes. This array is indexed by vCPU ID.

An I/O client, which is 'struct acrn_ioreq_client', is responsible for
handling User VM I/O requests whose accessed GPA falls in a certain
range. Multiple I/O clients can be associated with each User VM. There
is a special client associated with each User VM, called the default
client, that handles all I/O requests that do not fit into the range of
any other I/O clients. The ACRN userspace acts as the default client for
each User VM.

The state transitions of a ACRN I/O request are as follows.

   FREE -> PENDING -> PROCESSING -> COMPLETE -> FREE -> ...

FREE: this I/O request slot is empty
PENDING: a valid I/O request is pending in this slot
PROCESSING: the I/O request is being processed
COMPLETE: the I/O request has been processed

An I/O request in COMPLETE or FREE state is owned by the hypervisor. HSM
and ACRN userspace are in charge of processing the others.

The processing flow of I/O requests are listed as following:

a) The I/O handler of the hypervisor will fill an I/O request with
   PENDING state when a trapped I/O access happens in a User VM.
b) The hypervisor makes an upcall, which is a notification interrupt, to
   the Service VM.
c) The upcall handler schedules a worker to dispatch I/O requests.
d) The worker looks for the PENDING I/O requests, assigns them to
   different registered clients based on the address of the I/O accesses,
   updates their state to PROCESSING, and notifies the corresponding
   client to handle.
e) The notified client handles the assigned I/O requests.
f) The HSM updates I/O requests states to COMPLETE and notifies the
   hypervisor of the completion via hypercalls.

[PATCH v9 10/18] virt: acrn: Introduce PCI configuration space PIO accesses combiner

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

A User VM can access its virtual PCI configuration spaces via port IO
approach, which has two following steps:
 1) writes address into port 0xCF8
 2) put/get data in/from port 0xCFC

To distribute a complete PCI configuration space access one time, HSM
need to combine such two accesses together.

Combine two paired PIO I/O requests into one PCI I/O request and
continue the I/O request distribution.

[PATCH v9 11/18] virt: acrn: Introduce interfaces for PCI device passthrough

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

PCI device passthrough enables an OS in a virtual machine to directly
access a PCI device in the host. It promises almost the native
performance, which is required in performance-critical scenarios of
ACRN.

HSM provides the following ioctls:
 - Assign - ACRN_IOCTL_ASSIGN_PCIDEV
   Pass data struct acrn_pcidev from userspace to the hypervisor, and
   inform the hypervisor to assign a PCI device to a User VM.

 - De-assign - ACRN_IOCTL_DEASSIGN_PCIDEV
   Pass data struct acrn_pcidev from userspace to the hypervisor, and
   inform the hypervisor to de-assign a PCI device from a User VM.

 - Set a interrupt of a passthrough device - ACRN_IOCTL_SET_PTDEV_INTR
   Pass data struct acrn_ptdev_irq from userspace to the hypervisor,
   and inform the hypervisor to map a INTx interrupt of passthrough
   device of User VM.

 - Reset passthrough device interrupt - ACRN_IOCTL_RESET_PTDEV_INTR
   Pass data struct acrn_ptdev_irq from userspace to the hypervisor,
   and inform the hypervisor to unmap a INTx interrupt of passthrough
   device of User VM.

[PATCH v9 12/18] virt: acrn: Introduce interrupt injection interfaces

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

ACRN userspace need to inject virtual interrupts into a User VM in
devices emulation.

HSM needs provide interfaces to do so.

Introduce following interrupt injection interfaces:

ioctl ACRN_IOCTL_SET_IRQLINE:
  Pass data from userspace to the hypervisor, and inform the hypervisor
  to inject a virtual IOAPIC GSI interrupt to a User VM.

ioctl ACRN_IOCTL_INJECT_MSI:
  Pass data struct acrn_msi_entry from userspace to the hypervisor, and
  inform the hypervisor to inject a virtual MSI to a User VM.

ioctl ACRN_IOCTL_VM_INTR_MONITOR:
  Set a 4-Kbyte aligned shared page for statistics information of
  interrupts of a User VM.

[PATCH v9 13/18] virt: acrn: Introduce interfaces to query C-states and P-states allowed by hypervisor

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

The C-states and P-states data are used to support CPU power management.
The hypervisor controls C-states and P-states for a User VM.

ACRN userspace need to query the data from the hypervisor to build ACPI
tables for a User VM.

HSM provides ioctls for ACRN userspace to query C-states and P-states
data obtained from the hypervisor.

[PATCH v9 14/18] virt: acrn: Introduce I/O ranges operation interfaces

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

An I/O request of a User VM, which is constructed by hypervisor, is
distributed by the ACRN Hypervisor Service Module to an I/O client
corresponding to the address range of the I/O request.

I/O client maintains a list of address ranges. Introduce
acrn_ioreq_range_{add,del}() to manage these address ranges.

[PATCH v9 15/18] virt: acrn: Introduce ioeventfd

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

ioeventfd is a mechanism to register PIO/MMIO regions to trigger an
eventfd signal when written to by a User VM. ACRN userspace can register
any arbitrary I/O address with a corresponding eventfd and then pass the
eventfd to a specific end-point of interest for handling.

Vhost is a kernel-level virtio server which uses eventfd for signalling.
To support vhost on ACRN, ioeventfd is introduced in HSM.

A new I/O client dedicated to ioeventfd is associated with a User VM
during VM creation. HSM provides ioctls to associate an I/O region with
a eventfd. The I/O client signals a eventfd once its corresponding I/O
region is matched with an I/O request.

[PATCH v9 16/18] virt: acrn: Introduce irqfd

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

irqfd is a mechanism to inject a specific interrupt to a User VM using a
decoupled eventfd mechanism.

Vhost is a kernel-level virtio server which uses eventfd for interrupt
injection. To support vhost on ACRN, irqfd is introduced in HSM.

HSM provides ioctls to associate a virtual Message Signaled Interrupt
(MSI) with an eventfd. The corresponding virtual MSI will be injected
into a User VM once the eventfd got signal.

[PATCH v9 17/18] virt: acrn: Introduce an interface for Service VM to control vCPU

[shuo.a.liu]

From: Shuo Liu <shuo.a.liu@intel.com>

ACRN supports partition mode to achieve real-time requirements. In
partition mode, a CPU core can be dedicated to a vCPU of User VM. The
local APIC of the dedicated CPU core can be passthrough to the User VM.
The Service VM controls the assignment of the CPU cores.

Introduce an interface for the Service VM to remove the control of CPU
core from hypervisor perspective so that the CPU core can be a dedicated
CPU core of User VM.

Does this mean that ACRN has a limit of 16 vCPUs ?
