## Default features of crosvm. This selection is somewhat arbitrary for historical reasons.
default = ["audio", "balloon", "config-file", "document-features", "gpu", "qcow", "usb", "libvda-stub", "net", "slirp"]

## Enables support for the Android [sparse image format](https://android.googlesource.com/platform/system/core/+/HEAD/libsparse/sparse_format.h)
## in the block device.
android-sparse = ["disk/android-sparse"]

## Enables cross-platform audio devices
audio = ["devices/audio"]

## Enables the virtio-balloon device which allows dynamic scaling of memory via `vm_control`
## commands. See [Balloon Device](https://crosvm.dev/book/devices/balloon.html) for more
## information.
balloon = ["devices/balloon", "vm_control/balloon"]

## Enables the composite-disk format, which adds protobufs as a dependency of the build. This format
## is intended to speed up crosvm's usage in CI environments that might otherwise have to
## concatenate large file system images into a single disk image.
composite-disk = ["protos/composite-disk", "protobuf", "disk/composite-disk"]

## Enables virtiofs uid-gid mapping from the host side through command line when user-namespace
## isn't available for non-root users. This format is supported only for vhost-user-fs.
fs_runtime_ugid_map = ["devices/fs_runtime_ugid_map"]

## Enables support for JSON configuration files that can be specified using `--cfg`. See
## [Configuration Files](https://crosvm.dev/book/running_crosvm/options.html#configuration-files)
## for more information.
config-file = []

## Enables using gdb to debug the guest kernel. See
## [GDB Support](https://crosvm.dev/book/running_crosvm/advanced_usage.html#gdb-support) for more
## information.
gdb = [
    "aarch64/gdb",

    "gdbstub",
    "gdbstub_arch",

    "vm_control/gdb",
    "x86_64/gdb",
]

## Enables virtio-net and vhost-user-net backend.
net = ["devices/net"]

## Enables PCI hotplug. Only available on Linux, and currently only for x86/x86-64.
pci-hotplug = ["devices/pci-hotplug", "vm_control/pci-hotplug"]

## Enables virtio-pvclock. Currently only available for x86-64 and aarch64.
pvclock = ["devices/pvclock"]

## Enables the use of the qcow format for block devices.

## Enables the non-upstream virtio wayland protocol. This can be used in conjuction with the gpu
## feature to enable a zero-copy display pipeline.
wl-dmabuf = ["devices/minigbm"]

## Enables the usage of the X11 protocol for display on the host.

#! ### Graphics features

## Enables basic virtio-gpu support. This includes basic display and input features, but lacks 3D
## acceleration in the absence of other crosvm features.
gpu = ["devices/gpu", "gpu_display", "vm_control/gpu"]

## Enables 3D acceleration for guest via the gfxstream protocol over virtio-gpu. This is used for
## compatibility with the Android Emulator. The protocol provides the best speed and compatibility
## with GL/vulkan versions by forwarding the guest's calls to the host's graphics libraries and GPU.
## However, this means the sandbox is not enabled for the virtio-gpu device.
gfxstream = ["devices/gfxstream"]

## Adds a stub implementation of gfxstream to allow us to compile the gfxstream feature without
## access to the gfxstream library.
## Note that this feature only allows compilation of gfxstream and will not be functional at
## runtime.
gfxstream_stub = ["rutabaga_gfx/gfxstream_stub"]

## Enables 3D acceleration for the guest via the virglrenderer library over virtio-gpu.
virgl_renderer = ["devices/virgl_renderer"]

## Enables the usage of Vulkan for display on the host.

# Enables the highly experimental vulkan graphics buffer allocator.
# see rutabaga_gfx/Cargo.toml for instructions on building with enabled.
vulkano = ["rutabaga_gfx/vulkano"]

# Enables the GPU display backend for Android. The backend uses Android surface as the backing
# store.
android_display = ["devices/android_display"]

# Stub implementation of the Android display backend. This is only used for building and testing the
# Android display backend on a non-Android target
android_display_stub = ["devices/android_display_stub"]

#! ### Video features
#!
#! See [Video Device](https://crosvm.dev/book/devices/video.html) for more information.

## Enables the video decoding device
video-decoder = ["devices/video-decoder"]

## Enables the video encoding device
video-encoder = ["devices/video-encoder"]

## Enables the ffmpeg backend of video devices.

# Enables the VAAPI backend of video devices.
vaapi = ["devices/vaapi"]

#! ### Linux-specific feature flags

## Enables the use of the GenieZone hypervisor
geniezone = ["devices/geniezone", "hypervisor/geniezone"]

## Enables the use of the Gunyah hypervisor
gunyah = ["devices/gunyah", "hypervisor/gunyah"]

## Enables the Linux trace_marker backend for cros_tracing. This backend is only
## supported on Linux systems. It sends all cros_tracing tracepoints to the tracefs
## filesystem if mounted, for easier debugging with tools like trace-cmd.
trace_marker = ["cros_tracing/trace_marker"]

## Facilitate tracing all syscalls by sandboxed processes.
seccomp_trace = ["jail/seccomp_trace","base/seccomp_trace","devices/seccomp_trace"]

## Enables virtio-gpu devices to request a non-coherent memory mapping from the
## hypervisor. Currently only supported in KVM on x86 and requires kernel
## patches from:
## <https://lore.kernel.org/all/20240105091535.24760-1-yan.y.zhao@intel.com/>
noncoherent-dma = ["devices/noncoherent-dma", "hypervisor/noncoherent-dma"]

#! ### Windows-specific feature flags
#!
#! These feature flags are only available on Windows builds of crosvm.

## Enables the use of the HAXM hypervisor
haxm = ["hypervisor/haxm"]

## Enables the use of the WHPX hypervisor
whpx = ["devices/whpx", "hypervisor/whpx"]

## Enables a libslirp based network device. Currently only supported on Windows.
slirp = ["devices/slirp", "net_util/slirp"]

## Enables slirp debugging.
slirp-debug = ["net_util/slirp-debug"]

## Enables slirp capture.
slirp-ring-capture = [
    "net_util/slirp-ring-capture",
    "devices/slirp-ring-capture",
]

#! ### Non-additive feature flags
#!
#! These feature flags change the behavior of crosvm instead of adding functionality.
#! This is deprecated and will be phased out.

## Run crosvm with `--disable-sandbox` by default.
default-no-sandbox = []

#! ### Project specific features
#!
#! These features are specific to downstream projects and may not be functional or useful
#! for standard linux builds of crosvm.
#! They are however enabled in upstream builds for compile and test coverage in CI.

#! #### ChromeOS
#!
#! These features will only be functional in ChromeOS builds running on ChromeOS.

## Enables ARCVM specified virtio-fs feature including:
## - Support quota reporting for ARCVM
##   Requires access to the org.chromium.ArcQuota dbus service.
## - Support for FS_IOC_SETPERMISSION ioctl
## - Support for FS_IOC_SETPATHXATTR ioctl
arc_quota = ["devices/arc_quota"]

## Enables use of Android AAudio virtio-snd backend.
audio_aaudio = ["devices/audio_aaudio"]

## Stub implementation of Android AAudio NDK library. This is only used for building and testing the
## Android audio on a non-Android target
libaaudio_stub = ["android_audio/libaaudio_stub"]

## Enables use of the ChromeOS audio server. ChromeOS builds will replace libcras_stub with an
## implementation that talks to the audio server. In upstream builds, using this option will panic.
audio_cras = ["devices/audio_cras"]

## Enables the VDA backend of the video devices. This feature requires the ChromeOS only
## libvda library and can be compiled but not linked. See b/244619291.
libvda = ["devices/libvda"]

## Builds the VDA video backend with a set of no-ops stubs instead of linking with libvda, which is
## only available on ChromeOS.
libvda-stub = ["devices/libvda-stub"]

## Enables the crosvm plugin API where functionality is provided via a FFI plugin API.
## This feature is used to integrate Parallels with crosvm and is not functional upstream.
plugin = ["protos/plugin", "crosvm_plugin", "kvm", "kvm_sys", "protobuf"]

## Enables battery reporting via the ChromeOS powerd. Requires access to the
## `org.chromium.PowerManager` dbus service.
power-monitor-powerd = ["arch/power-monitor-powerd"]

## Enables a virtualized TPM device that uses the `org.chromium.Vtpm` dbus service.
vtpm = ["devices/vtpm"]

#!
#! These features will only be functional in future builds of windows crosvm.

## Enables reporting of crosvm crashes
