+# Device Trees in AVF
+
+This document aims to provide a centralized overview of the way the Android
+Virtualization Framework (AVF) composes and validates the device tree (DT)
+received by protected guest kernels, such as [Microdroid].
+
+[Microdroid]: ../guest/microdroid/README.md
+
+## Context
+
+As of Android 15, AVF only supports protected virtual machines (pVMs) on
+AArch64. On this architecture, the Linux kernel and many other embedded projects
+have adopted the [device tree format][dtspec] as the way to describe the
+platform to the software. This includes so-called "[platform devices]" (which are
+non-discoverable MMIO-based devices), CPUs (number, characteristics, ...),
+memory (address and size), and more.
+
+With virtualization, it is common for the virtual machine manager (VMM, e.g.
+crosvm or QEMU), typically a host userspace process, to generate the DT as it
+configures the virtual platform. In the case of AVF, the threat model prevents
+the guest from trusting the host and therefore the DT must be validated by a
+trusted entity. To avoid adding extra logic in the highly-privileged hypervisor,
+AVF relies on [pvmfw], a small piece of code that runs in the context of the
+guest (but before the guest kernel), loaded by the hypervisor, which validates
+the untrusted device tree. If any anomaly is detected, pvmfw aborts the boot of
+the guest. As a result, the guest kernel can trust the DT it receives.
+
+The DT sanitized by pvmfw is received by guests following the [Linux boot
+protocol][booting.txt] and includes both virtual and physical devices, which are
+hardly distinguishable from the guest's perspective (although the context could
+provide information helping to identify the nature of the device e.g. a
+virtio-blk device is likely to be virtual while a platform accelerator would be
+physical). The guest is not expected to treat physical devices differently from
+virtual devices and this distinction is therefore not relevant.
+
+```

+[booting.txt]: https://www.kernel.org/doc/Documentation/arm64/booting.txt
+
+## Device Tree Generation (Host-side)
+
+crosvm describes the virtual platform to the guest by generating a DT
+enumerating the memory region, virtual CPUs, virtual devices, and other
+properties (e.g. ramdisk, cmdline, ...). For physical devices (assigned using
+VFIO), it generates simple nodes describing the fundamental properties it
+configures for the devices i.e. `<reg>`, `<interrupts>`, `<iommus>`
+(respectively referring to IPA ranges, vIRQs, and pvIOMMUs).
+
+It is possible for the caller of crosvm to pass more DT properties or nodes to
+the guest by providing device tree overlays (DTBO) to crosvm. These overlays get
+applied after the DT describing the configured platform has been generated, the
+final result getting passed to the guest.
+
+For physical devices, crosvm supports applying a "filtered" subset of the DTBO
+received, where subnodes are only kept if they have a label corresponding to an
+assigned VFIO device. This allows the caller to always pass the same overlay,
+irrespective of which physical devices are being assigned, greatly simplifying
+the logic of the caller. This makes it possible for crosvm to support complex
+nodes for physical devices without including device-specific logic as any extra
+property (e.g. `<compatible>`) will be passed through the overlay and added to
+the final DT in a generic way. This _vm DTBO_ is read from an AVB-verified
+partition (see `ro.boot.hypervisor.vm_dtbo_idx`).
+
+Otherwise, if the `filter` option is not used, crosvm applies the overlay fully.
+This can be used to supplement the guest DT with nodes and properties which are
+not tied to particular assigned physical devices or emulated virtual devices. In
+particular, `virtualizationservice` currently makes use of it to pass
+AVF-specific properties.
+
+```
+            ┌─►{DTBO,filter}─┐
+┌─────────┐ │                │  ┌────────┐
+│ virtmgr ├─┼────►{DTBO}─────┼─►│ crosvm ├───►{guest DT}───► ...
+└─────────┘ │                │  └────────┘
+            └─►{VFIO sysfs}──┘
+```
+
+## Device Tree Sanitization
+
+pvmfw intercepts the boot sequence of the guest and locates the DT generated by
+the VMM through the VMM-guest ABI. A design goal of pvmfw is to have as little
+side-effect as possible on the guest so that the VMM can keep the illusion that
+it configured and booted the guest directly and the guest does not need to rely
+or expect pvmfw to have performed any noticeable work (a noteworthy exception
+being the memory region describing the [DICE chain]). As a result, both VMM and
+guest can mostly use the same logic between protected and non-protected VMs
+(where pvmfw does not run) and keep the simpler VMM-guest execution model they
+are used to. In the context of pvmfw and DT validation, the final DT passed by
+crosvm to the guest is typically referred to as the _input DT_.

+
+### Virtual Platform
+
+The DT sanitization policy in pvmfw matches the virtual platform defined by
+crosvm and its implementation is therefore tightly coupled with it (this is one
+reason why AVF expects pvmfw and the VMM to be updated in sync). It covers
+fundamental properties of the platform (e.g.  location of main memory,
+properties of CPUs, layout of the interrupt controller, ...) and the properties
+of (sometimes optional) virtual devices supported by crosvm and used by AVF
+guests.
+
+### Physical Devices
+
+To support device assignment, pvmfw needs to be able to validate physical
+platform-specific device properties. To achieve this in a platform-agnostic way,
+pvmfw receives a DT overlay (called the _VM DTBO_) from the Android Bootloader
+(ABL), containing a description of all the assignable devices. By detecting
+which devices have been assigned using platform-specific reserved DT labels, it
+can validate the properties of the physical devices through [generic logic].
+pvmfw also verifies with the hypervisor that the guest addresses from the DT
+have been properly mapped to the expected physical addresses of the devices; see
+[_Getting started with device assignment_][da.md].
+
+Note that, as pvmfw runs within the context of an individual pVM, it cannot
+detect abuses by the host of device assignment across guests (e.g.
+simultaneously assigning the same device to multiple guests), and it is the
+responsibility of the hypervisor to enforce this isolation. AVF also relies on
+the hypervisor to clear the state of the device on donation and (most
+importantly) on return to the host so that pvmfw does not need to access the
+assigned devices.
+
+[generic logic]: ../guest/pvmfw/src/device_assignment.rs
+[da.md]: ../docs/device_assignment.md
+
+### Extra Properties (Security-Sensitive)
+
+Some AVF use-cases require passing platform-specific inputs to protected guests.
+If these are security-sensitive, they must also be validated before being used
+by the guest. In most cases, the DT property is platform-agnostic (and supported
+by the generic guest) but its value is platform-specific. The _reference DT_ is
+an [input of pvmfw][pvmfw-config] (received from the loader) and used to
+validate DT entries which are:
+
+- security-sensitive: the host should not be able to tamper with these values
+- not confidential: the property is visible to the host (as it generates it)
+- Same across VMs: the property (if present) must be same across all instances
+- possibly optional: pvmfw does not abort the boot if the entry is missing
+
+[pvmfw-config]: ../guest/pvmfw/README.md#configuration-data-format
+
+### Extra Properties (Host-Generated)
+
+Finally, to allow the host to generate values that vary between guests (and
+which therefore can't be described using one the previous mechanisms), pvmfw
+treats the subtree of the input DT at path `/avf/untrusted` differently: it only
+performs minimal sanitization on it, allowing the host to pass arbitrary,
+unsanitized DT entries. Therefore, this subtree must be used with extra
+validation by guests e.g. only accessed by path (where the name, "`untrusted`",
+acts as a reminder), with no assumptions about the presence or correctness of
+nodes or properties, without expecting properties to be well-formed, ...
+
+In particular, pvmfw prevents other nodes from linking to this subtree
+(`<phandle>` is rejected) and limits the risk of guests unexpectedly parsing it
+other than by path (`<compatible>` is also rejected) but guests must not support
+non-standard ways of binding against nodes by property as they would then be
+vulnerable to attacks from a malicious host.
+
+### Implementation details
+
+DT sanitization is currently implemented in pvmfw by parsing the input DT into
+temporary data structures and pruning a built-in device tree (called the
+_platform DT_; see [platform.dts]) accordingly. For device assignment, it prunes
+the received VM DTBO to only keep the devices that have actually been assigned
+(as the overlay contains all assignable devices of the platform).
+
+[platform.dts]: ../guest/pvmfw/platform.dts
+
+## DT for guests
+
+### AVF-specific properties and nodes
+
+For Microdroid and other AVF guests, some special DT entries are defined:
+
+- the `/chosen/avf,new-instance` flag, set when pvmfw triggered the generation
+  of a new set of CDIs (see DICE) _i.e._ the pVM instance was booted for the
+  first time. This should be used by the next stages to synchronise the
+  generation of new CDIs and detect a malicious host attempting to force only
+  one stage to do so. This property becomes obsolete (and might not be set) when
+  [deferred rollback protection] is used by the guest kernel;
+
+- the `/chosen/avf,strict-boot` flag, always set for protected VMs and can be
+  used by guests to enable extra validation;
+
+- the `/avf/untrusted/defer-rollback-protection` flag controls [deferred
+  rollback protection] on devices and for guests which support it;
+
+- the host-allocated `/avf/untrusted/instance-id` is used to assign a unique
+  identifier to the VM instance & is used for differentiating VM secrets as well
+  as by guest OS to index external storage such as Secretkeeper.
+

+# Microfuchsia
+
+Microfuchsia is an experimental solution for running trusted applications on
+pkvm using the Android Virtualization Framework (AVF).
+
+# How to use
+
+Add the `com.android.microfuchsia` apex to your product.
+
+```
+PRODUCT_PACKAGES += com.android.microfuchsia
+```
+
+Define and add a `com.android.microfuchsia.images` apex to hold the images.
+
+```
+PRODUCT_PACKAGES += com.android.microfuchsia.images
+```
+
+This apex must have a prebuilt `fuchsia.zbi` in `/etc/fuchsia.zbi` and a boot
+shim in `/etc/linux-arm64-boot-shim.bin`.
+
+# Using the console
+
+This command will open the console for the first VM running in AVF, and can be
+used to connect to the microfuchsia console.
+
+```
+adb shell -t /apex/com.android.virt/bin/vm console
+```
