 ## implementation that talks to the audio server. In upstream builds, using this option will panic.

 ## 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.

 #!
 #! These feature flags enable all features that are supported for a given platform.

	#!
	#! 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

	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/>

	#!

	haxm = ["hypervisor/haxm"]

	## Enables the use of the WHPX hypervisor

	#! ### 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.

	#! ### 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 virtio-fs quota reporting for ARCVM. Requires access to the
	## org.chromium.ArcQuota dbus service.
	arc_quota = ["devices/arc_quota"]

	## 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"]

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

	## Enables reporting of crosvm crashes
	crash-report = ["broker_ipc/crash-report", "crash_report"]

	#! ### Platform Feature Sets
	#!
	#! These feature flags enable all features that are supported for a given platform.
	#! Note that these may include project specific features that will not be functional at runtime but
	#! are enabled for compile and test coverage.
