GN Build Arguments

All builds

acpica_debug_output

Enable debug output in the ACPI library (used by the ACPI bus driver).

Current value (from the default): false

From //zircon/system/ulib/acpica/acpica.gni:7

active_partition

Current value (from the default): ""

From //build/images/args.gni:114

add_qemu_to_build_archives

Whether to include images necessary to run Fuchsia in QEMU in build archives.

Current value (from the default): false

From //build/images/args.gni:120

additional_boards

Additional boards (such as vendor boards) that are to be added to the build graph, and built when all boards for a given architecture are built. These boards MUST be valid in the configured default_toolchain, and be for the current ‘target_cpu’.

Current value (from the default): []

From //boards/BUILD.gn:13

additional_boot_args

List of arguments to add to /boot/config/additional_boot_args. These come after synthesized arguments to configure blobfs and pkgfs.

Current value (from the default): []

From //build/images/args.gni:24

additional_bootserver_arguments

Additional bootserver args to add to pave.sh. New uses of this should be added with caution, and ideally discussion. The present use case is to enable throttling of netboot when specific network adapters are combined with specific boards, due to driver and hardware challenges.

Current value (from the default): ""

From //build/images/args.gni:126

all_cpu_kernel_boot_tests

Cause //zircon/kernel:boot_tests to generate the phys boot tests for all supported CPUs, not just $target_cpu.

List of file paths to every font asset. Populated in fonts.gni.

Current value (from the default): []

From //src/fonts/build/font_args.gni:35

all_toolchain_variants

These should never be set as a build argument. It will be set below and passed to other toolchains through toolchain_args (see variant_toolchain.gni).

Current value (from the default): []

From //build/config/BUILDCONFIG.gn:2099

allowed_test_device_types

A list of device types this build is allowed to run tests on. If set, only these device types will be used for tests.

From //src/diagnostics/archivist/configs.gni:6

arm_sdk_tools

If true, then the arm64 host tools are included in the SDK.

Current value (from the default): false

From //src/developer/ffx/plugins/emulator/emu_companion.gni:9

asan_default_options

Default AddressSanitizer options (before the ASAN_OPTIONS environment variable is read at runtime). This can be set as a build argument to affect most “asan” variants in $variants (which see), or overridden in $toolchain_args in one of those variants. This can be a list of strings or a single string.

Note that even if this is empty, programs in this build cannot define their own __asan_default_options C function. Instead, they can use a sanitizer_extra_options() target in their deps and then any options injected that way can override that option's setting in this list.

Current value (from the default): ["detect_stack_use_after_return=1", "quarantine_size_mb=32"]

From //build/config/sanitizers/sanitizer_default_options.gni:16

Current value (from the default): false

From //build/images/args.gni:149

assembly_generate_fvm_nand

Specifying these variables will generate a NAND FVM image suitable for directly flashing via fastboot. The NAND characteristics are required in order to properly initialize the FTL metadata in the OOB area. fvm_max_disk_size should also be nonzero or else minfs will not have any room to initialize on boot.

Current value (from the default): false

From //build/images/args.gni:156

authorized_ssh_keys_label

Path to the file containing the authorized keys that are able to connect via ssh. This is in the format used by Bazel, and by GN‘s labels, but not by GN’s file path syntax:

authorized_ssh_keys_label = “//path/to/folder:file_name”

To GN, this path should be:

“//path/to/folder/file_name”

But to pass it as a file to the Bazel build, we need to use the “label” syntax, which is going to be fixed up below.

Current value (from the default): false

From //build/bazel/logging.gni:11

bazel_fuchsia_sdk_all_cpus

Set to true to populate the @fuchsia_sdk external repository with prebuilt binaries for all supported target CPU architectures. By default, only those for the current build configuration's target_cpu value will be generated to save about 3 minutes of build time when they are not needed.

bazel_product_bundle_[prefix|board] together identifies the bazel_product_bundle target in GN target to use in Bazel assembly. The actual target used is:

${bazel_product_bundle_prefix}.${bazel_product_bundle_board}

NOTE: bazel_product_bundle_prefix should contain the fully qualified path prefix to the target. Setting both arguments is a prerequisite to enable Bazel assembly.

For example, given:

bazel_product_bundle_prefix = “//build/bazel/assembly:minimal” bazel_product_bundle_board = “x64”

The actual bazel_product_bundle used for Bazel assembly is:

//build/bazel/assembly:minimal.x64

Current value (from the default): false

create_legacy_aib_archive

Create the package and archive for the legacy assembly input bundle. This can be a time-consuming operation, which due to limits in GN and groups, ends up being a blocking step in the build, so only enable this if we know that we want the legacy AIB packaged and archived for a given product:

Current value (from the default): []

From //build/images/custom_signing.gni:18

custom_signing_script_tools

If custom signing script is not empty, a list of host tool labels, without a toolchain, that the script depends on. The reason why these are not in custom_signing_script_deps is because these definitions are typically in board-specific .gni files where host_os or host_toolchain are not defined yet.

cxx_rbe_check

Run one of the more expensive checks, intended for CI. All of these require cxx_rbe_enable=true.

One of:

  • “none”: No additional check.

  • “determinism”: Check of determinism of C++ targets by running locally twice and comparing outputs, failing if any differences are found. Even though this check doesn't involve RBE, it uses the same wrapper script, which knows what output files to expect and compare.

    Build outputs that depend on time are discouraged because they impact caching. Known bad preprocessing macros include DATE and TIME.

  • “consistency”: Check consistency between local and remote C++ compiles, by running both and comparing results.

Current value (from the default): "none"

From //build/toolchain/rbe.gni:185

cxx_rbe_download_obj_files

Controls whether or not to download intermediate .o files. When downloading is disabled, the build produces stubs that be used to retrieve remote artifacts later using build/rbe/dlwrap.py.

cxx_rbe_exec_strategy

One of:

  • “remote”: Execute action remotely on cache miss. The remote cache is always updated with this result.

  • “local”: Lookup action in the remote cache, but execute action locally on cache miss. The locally produced result is not uploaded to the remote cache.

  • “remote_local_fallback”: Execute action remotely first. If that fails, run locally instead. The locally produced results are not uploaded to the remote cache.

  • “racing”: Race local vs. remote execution, take the first to finish.

(There are other rewrapper options that are not exposed.)

Current value (from the default): "remote_local_fallback"

From //build/toolchain/rbe.gni:161

cxx_rbe_minimalist_wrapper

Set to true to use a fast, minimalist wrapper, that lacks features of the python-based wrapper. Use with caution. This flag is only meaningful when cxx_rbe_enable is true.

Current value (from the default): true

From //build/toolchain/rbe.gni:143

data_filesystem_format

If you add package labels to this variable, the packages will be included in the ‘discoverable’ package set, as defined by RFC-0212 “Package Sets”: https://fuchsia.dev/fuchsia-src/contribute/governance/rfcs/0212_package_sets

They will be compiled, and published, but not added as dependencies of the assembled images, and so will not be able to cause the inclusion of ‘config_data’ or ‘shell_command’ entries.

As these cannot be part of the legacy AIB for a product, there is no “legacy” version of this argument.

enable_frame_pointers

Controls whether the compiler emits full stack frames for function calls. This reduces performance but increases the ability to generate good stack traces, especially when we have bugs around unwind table generation. It applies only for Fuchsia targets (see below where it is unset).

enable_perfetto_traced_probes

The traced_probes daemon is very Linux-specific, as it depends on ftrace and various /proc interfaces. There is no point making its code platform-neutral as it won't do anything useful on Windows. The only reason why we still build it on Mac OS is to be able to run the unittests there and making dev on mac less cumbersome. The traced_probes code happens to build cleanly and for now the mainteinance cost on Mac is extremely low.

Current value (from the default): false

enable_suspend

While suspend is being developed we define this flag which enables all suspend features. Developers working on suspend can then simply add this one flag to their build arguments.

Current value (from the default): false

From //build/suspend/config.gni:9

enable_virtual_heap

Enables the use of a virtually managed kernel heap instead of one managed directly out of the physmap. The virtual heap may have some performance and memory usage overheads, but will not exhaust due to fragmentation.

Current value (from the default): false

From //zircon/kernel/params.gni:118

escher_test_for_glsl_spirv_mismatch

If true, this enables the |SpirvNotChangedTest| to check if the precompiled shaders on disk are up to date and reflect the current shader source code compiled with the latest shaderc tools/optimizations. People on the Scenic team should build with this flag turned on to make sure that any shader changes that were not run through the precompiler have their updated spirv written to disk. Other teams and CQ do not need to worry about this flag.

Current value (from the default): false

From //src/ui/lib/escher/build_args.gni:18

escher_use_runtime_glsl

Determines whether or not escher will build with the glslang and shaderc libraries. When false, these libraries will not be included in the scenic/ escher binary and as a result shaders will not be able to be compiled at runtime. Precompiled spirv code will be loaded into memory from disk instead.

Current value (from the default): false

From //src/ui/lib/escher/build_args.gni:10

exclude_testonly_syscalls

If true, excludes syscalls with the [testonly] attribute.

Current value (from the default): false

experimental_cxx_version

NOTE: This is for experimentation only and should not normally be changed. Set the version of the C++ standard to compile for, 17 or 20. Note also that GN code should never use this variable directly, but always instead use the fuchsia_cxx_version variable.

Current value (from the default): 17

From //build/config/fuchsia_cxx_version.gni:10

extra_bazel_assembly_targets

Extra GN targets to include when Bazel assembly is enabled. This list is useful for including verification and other Bazel assembly specific targets.

Current value (from the default): []

From //build/images/args.gni:211

extra_gn_labels_for_bazel_inputs

A list of extra labels to bazel_input_xxx() targets that complement gn_labels_for_bazel_inputs. These labels can be defined anywhere, including the //vendor/... directory.

This can be set in args.gn by vendor-specific build configurations. Consider the following example from a fictitious //vendor/acme/proprietary/BUILD.gn file:

 # Generate the firmware for our device.
 action("generate_firmware") {
   ...
 }

 # Ensure the generated firmware is visible to Bazel as a filegroup()
 # @legacy_ninja_build_outputs repository//:acme_firmware
 bazel_input_resource("acme_firmware") {
   deps = [ ":generate_firmware" ]
   sources = get_target_outputs(deps[0])
   outputs = [ "{{source_file_part}}" ]
   visibility = [ ":*" ]
 }

 # Build the installer with Bazel.
 bazel_action("build_installer") {
   command = "build"
   bazel_targets = "//vendor/acme/proprietary/installer"
   bazel_inputs = [ ":acme_firmware" ]
   copy_outputs = [
     {
       bazel = "vendor/acme/proprietary/installer/installer"
       ninja = "installer"
     }
   ]
 }

Which requires the following, which could be in args.gn, or in a file imported from it (e.g. //vendor/acme/products/device.gni):

extra_gn_labels_for_bazel_inputs = [ “//vendor/acme/proprietary:acme_firmware” ]

In order to ensure that the @legacy_ninja_build_outputs//:acme_firmware filegroup() will be defined and properly generated before building vendor/acme/proprietary:build_installer with Ninja:

ffx_build_dual_mode_plugins_as_subtools

Build any ffx plugins that can be built either as built-in or as separate subtools as subtools.

Note that if you change this and don't fx clean you may wind up with stale copies of either the main ffx binary (with all the plugins built in) or the separately compiled ones, and that might produce confusing ffx help or ffx commands output.

When all subtools that will be migrated to the SDK have been migrated, this config flag will be set to true by default, deprecated, and eventually removed: https://fxbug.dev/42068537

Current value (from the default): false

From //src/developer/ffx/config.gni:19

firmware_prebuilts

List of prebuilt firmware blobs to include in update packages.

Each entry in the list is a scope containing:

  • path: path to the image (see also firmware_prebuilts_path_suffix)
  • type: firmware type, a device-specific unique identifier
  • partition (optional): if specified, the fastboot flash partition

Current value (from the default): []

From //build/images/args.gni:60

firmware_prebuilts_path_suffix

Suffix to append to all firmware_prebuilts path variables.

Typically this indicates the hardware revision, and is made available so that users can easily switch revisions using a single arg.

fuchsia_async_trace_level_logging

Determines whether the fuchsia_async library used by many Rust targets will be compiled with TRACE level log statements that increase binary size a measurable amount. TODO(https://fxbug.dev/42161120) move this to a toolchain to allow multiple products to build together

Current value (from the default): true

From //build/product.gni:32

fuchsia_product_assembly_config_label

The product assembly config used to configure the main Fuchsia image. For GN products, this is required. For Bazel products, this is optional. For Bazel products, netboot will only be available when this is supplied.

Current value (from the default): false

From //build/product.gni:38

fuchsia_sdk_root

Consumers of the Fuchsia SDK instantiate templates for various SDK parts at a specific spot within their buildroots. The target name for the specific part is then derived from the part name as specified in the meta.json manifest. Different buildroot instantiate the SDK parts at different locations and then set this variable. GN rules can then prefix this variable name in SDK builds to the name of the SDK part. This flag is meaningless in non-SDK buildroots.

Current value (from the default): ""

gcc_tool_dir

Directory where the GCC toolchain binaries (“gcc”, “nm”, etc.) are found. This directory is expected to contain aarch64-elf-* and x86_64-elf-* tools used to build for the Fuchsia targets. This directory will not be used for host tools. If this is "", then a standard prebuilt is used.

Current value (from the default): ""

From //build/toolchain/zircon/gcc.gni:10

generate_cuckoo_tests

Defines the default value of kernel_zbi_test() template generate_cuckoo parameters. When true, all instances of kernel_zbi_tests() will default to generating a cuckoo_zbi_test() which is a full system image generated for exfiltrating instrumentation data from a target system.

Current value (from the default): false

Current value (from the default): true

From //build/bazel/licenses/BUILD.gn:23

generate_licenses_spdx_stubs

When true, generated_licenses_spdx template will generate stub SPDX files with placeholder license. License gathering will be skipped. Since license gathering is resource intensive, this is useful for non-production builds that would run faster. The global configuration can be overwritten in specific generated_licenses_spdx template invocation via the generate_stub parameter.

Current value (from the default): true

From //build/licenses/generated_licenses_spdx.gni:14

generate_plasa_artifacts

If set, causes the plasa artifacts to be generated. Not all builds need to use the plasa artifacts, so we set the default to skip the generation.

Current value (from the default): false

From //build/sdk/plasa/config.gni:8

gigaboot_backends

gocache_dir

gocache_dir Directory GOCACHE environment variable will be set to. This directory will have build and test results cached, and is safe to be written to concurrently. If overridden, this directory must be a full path.

Current value (from the default): "/b/s/w/ir/x/w/fuchsia/out/not-default/.gocache"

From //build/go/go_build.gni:19

goma_dir

Directory containing the Goma source code. This can be a GN source-absolute path (“//...”) or a system absolute path.

Current value (from the default): "//prebuilt/third_party/goma/linux-x64"

Typically useful for initially flashing a device from zero-state.

Current value (from the default): ""

From //build/images/args.gni:84

graphics_compute_generate_debug_shaders

Set to true in your args.gn file to generate pre-processed and auto-formatted shaders under the “debug” sub-directory of HotSort and Spinel target generation output directories.

These are never used, but can be reviewed manually to verify the impact of configuration parameters, or when modifying a compute shader.

Example results:

out/default/ gen/src/graphics/lib/compute/ hotsort/targets/hs_amd_gcn3_u64/ comp/ hs_transpose.comp -> unpreprocessed shader debug/ hs_transpose.glsl -> preprocessed shader

Current value (from the default): true

From //src/graphics/lib/compute/gn/glsl_shader_rules.gni:29

graphics_compute_generate_spirv_debug_info

If you‘re using GPU-assisted validation then it’s useful to include debug info in combination with skipping the spirv-opt and spirv-reduce pass.

Current value (from the default): false

From //src/graphics/lib/compute/gn/glsl_shader_rules.gni:47

graphics_compute_skip_spirv_opt

At times we may want to compare the performance of unoptimized vs. optimized shaders. On desktop platforms, use of spirv-opt doesn't appear to provide major performance improvements but it significantly reduces the size of the SPIR-V modules.

Disabling the spirv-opt pass may also be useful in identifying and attributing code generation bugs.

Current value (from the default): false

From //src/graphics/lib/compute/gn/glsl_shader_rules.gni:40

grpc_use_static_linking

TODO(169395837): Somehow gRPC symbols cannot be found on Android. Keep using static linking for now. In windows and mac use static linking.

host_tools_base_path_override

Set this to the path of a directory containing prebuilt binaries for the host tools generated by compiled_action(). This is useful when performing sub-builds (e.g. when generating the IDK which requires rebuilding SDK collections for different API levels and CPU architectures) to avoid rebuilding the host tools every time.

Current value (from the default): ""

From //build/host.gni:21

host_tools_dir

This is the directory where host tools intended for manual use by developers get installed. It‘s something a developer might put into their shell’s $PATH. Host tools that are just needed as part of the build do not get copied here. This directory is only for things that are generally useful for testing or debugging or whatnot outside of the GN build itself. These are only installed by an explicit install_host_tools() rule (see //build/host.gni).

Current value (from the default): "//out/not-default/host-tools"

From //build/host.gni:13

hwasan_default_options

Default HawrdwareAddressSanitizer options (before the HWASAN_OPTIONS environment variable is read at runtime). This can be set as a build argument to affect most “hwasan” variants in $variants (which see), or overridden in $toolchain_args in one of those variants. This can be a list of strings or a single string.

Note that even if this is empty, programs in this build cannot define their own __hwasan_default_options C function. Instead, they can use a sanitizer_extra_options() target in their deps and then any options injected that way can override that option's setting in this list.

Current value (from the default): ["allocator_may_return_null=1"]

If true, compile icu into a standalone static library. Currently this is only useful on Chrome OS.

Current value (from the default): false

From //build/icu.gni:19

icu_fuchsia_extra_compile_flags

Fuchsia sometimes requires extra compilation flags for ICU to adapt it to its current toolchain. Since it takes a while for ICU to roll through Fuchsia, it can take a long time from an ICU commit to a fix rolling into Fuchsia. This flag allows us to define the flag ahead of time in //build/icu.gni, and remove the rollout issues.

Current value (from the default): []

From //build/icu.gni:38

icu_fuchsia_override_data_dir

If set to nonempty, this is the label of the directory to be used to pull the ICU data files content. The setting has effect only when building inside the Fuchsia source tree.

Current value (from the default): ""

From //build/icu.gni:24

icu_major_version_number

Contains the major version number of the ICU library, for dependencies that need different configuration based on the library version. Currently this is only useful in Fuchsia.

Current value (from the default): "73"

From //third_party/icu/default/version.gni:13

icu_root

The GN files for the ICU library are located in this directory. Some Fuchsia builds use a different value here.

icu_tzres_path

Current value (from the default): "//prebuilt/third_party/tzres"

From //src/lib/icu/tzdata/icu_tzres_source.gni:26

icu_tzres_source

Which source location to use for ICU's time zone .res files: “git” or “prebuilt”.

If set to “git”, then the tzres files will contain the same time zone definitions as the ICU data monolith.

If set to “prebuilt”, then the tzres files will be retrieved from CIPD and may be newer than what's available in the ICU data monolith.

Current value (from the default): "prebuilt"

From //src/lib/icu/tzdata/icu_tzres_source.gni:16

icu_use_data_file

Tells icu to load an external data file rather than rely on the icudata being linked directly into the binary.

Current value (from the default): true

From //build/icu.gni:10

icu_use_stub_data

If true, then this creates a stub data file. This should be disabled if a custom data file will be used instead, in order to avoid conflicting symbols.

Current value (from the default): true

From //build/icu.gni:15

icu_use_target_out_dir

If set, the built libraries will live in their respective default output directories, not the root_build_dir.

include_shell_commands_package

Include the shell commands package. Used as a parameter to assembled_system(). See documentation there.

Current value (from the default): false

From //build/images/args.gni:174

include_zxdb_large_tests

Normally these tests are not built and run because they require large amounts of optional data be downloaded. Set this to true to enable the build for the zxdb_large_tests. See symbols/test_data/README.md for how to download the data required for this test.

Current value (from the default): false

From //src/developer/debug/zxdb/BUILD.gn:12

inet_config_enable_async_dns_sockets

Current value (from the default): true

From //src/fonts/tests/integration/BUILD.gn:21

is_analysis

If set, the build will produce compilation analysis dumps, used for code cross-referencing in code search. The extra work done during analysis is only needed for cross-referencing builds, so we're keeping the flag and the analysis overhead turned off by default.

Current value (from the default): false

From //build/config/BUILDCONFIG.gn:23

is_debug

Debug build.

Current value for target_cpu = "arm64": false

is_perfetto_build_generator

All the tools/gen_* scripts set this to true. This is mainly used to locate .gni files from //gn rather than //build.

Current value (from the default): false

From //third_party/perfetto/gn/perfetto.gni:82

is_perfetto_embedder

This is for override via gn args (e.g. for tools/gen_xxx). Embedders based on GN (e.g. v8) should NOT set this and instead directly sets perfetto_build_with_embedder=true in their GN files.

Current value (from the default): false

From //third_party/perfetto/gn/perfetto.gni:87

jtrace_enabled

Please refer to https://fuchsia.dev/fuchsia-src/development/debugging/jtrace for a description of these configuration options.

Note that the special value “auto” is used only by the default definitions of the entries (below). It acts as a special value which automatically chooses a default based on whether or not JTRACE is configured for persistent tracing, while still allowing a user to explicitly override the value regardless of whether persistent tracing is enabled or not.

kernel_based_memory_attribution_enabled

Controls the instantiation of AttributionObjects on ProcessDispatcher creation.

Current value (from the default): false

From //zircon/kernel/params.gni:142

kernel_debug_level

Enables various kernel debugging and diagnostic features. Valid values are between 0-3. The higher the value, the more that are enabled. A value of 0 disables all of them.

TODO(https://fxbug.dev/42117912): This value is derived from assert_level. Decouple the two and set kernel_debug_level independently.

Current value (from the default): 2

From //zircon/kernel/params.gni:106

kernel_debug_print_level

Controls the verbosity of kernel dprintf messages. The higher the value, the more dprintf messages emitted. Valid values are 0-2 (inclusive): 0 - CRITCAL / ALWAYS 1 - INFO 2 - SPEW

Current value (from the default): 2

From //zircon/kernel/params.gni:113

kernel_extra_defines

Extra macro definitions for kernel code, e.g. “DISABLE_KASLR”, “ENABLE_KERNEL_LL_DEBUG”.

Current value (from the default): []

From //zircon/kernel/params.gni:98

kernel_extra_deps

A list of GN labels comprising additional dependencies of the kernel proper. This can be useful - in a prototyping or ‘vendor’ capacity - for injecting new instances of subsystems that the kernel has defined modularly (e.g., pdev drivers or k commands).

Current value (from the default): []

From //zircon/kernel/BUILD.gn:40

kernel_no_userabi

Build a kernel with no user-space support, for development only.

Current value (from the default): false

From //zircon/kernel/params.gni:145

kernel_version_string

Version string embedded in the kernel for zx_system_get_version_string. If set to the default "", a string is generated based on the status of the fuchsia git repository.

Current value (from the default): ""

From //zircon/kernel/lib/version/BUILD.gn:18

kernel_zbi_extra_deps

A list of GN labels reaching zbi_input()-style targets to include in the kernel ZBI. These targets can be zbi_input(), kernel_cmdline(), etc. to inject ZBI items or resource(), etc. to inject items into the filesystem image that physboot decodes.

These are injected first, so an item that's itself a zbi_executable() or the like can be listed here to be used as a ZBI-to-ZBI boot shim (e.g. //zircon/kernel/arch/x86/phys/boot-shim:x86-legacy-zbi-boot-shim)

Current value (from the default): []

From //zircon/kernel/BUILD.gn:34

known_variants

List of variants that will form the basis for variant toolchains. To make use of a variant, set select_variant.

Normally this is not set as a build argument, but it serves to document the available set of variants. See also universal_variants. Only set this to remove all the default variants here. To add more, set extra_variants instead.

Each element of the list is one variant, which is a scope defining:

configs (optional) [list of labels] Each label names a config that will be automatically used by every target built in this variant. For each config ${label}, there must also be a target ${label}_deps, which each target built in this variant will automatically depend on. The variant() template is the recommended way to define a config and its _deps target at the same time.

remove_common_configs (optional) remove_shared_configs (optional) [list of labels] This list will be removed (with -=) from the default_common_binary_configs list (or the default_shared_library_configs list, respectively) after all other defaults (and this variant's configs) have been added.

deps (optional) [list of labels] Added to the deps of every target linked in this variant (as well as the automatic ${label}_deps for each label in configs).

name (required if configs is omitted) [string] Name of the variant as used in select_variant elements' variant fields. It's a good idea to make it something concise and meaningful when seen as e.g. part of a directory name under $root_build_dir. If name is omitted, configs must be nonempty and the simple names (not the full label, just the part after all /s and :s) of these configs will be used in toolchain names (each prefixed by a “-”), so the list of config names forming each variant must be unique among the lists in known_variants + extra_variants.

tags (optional) [list of strings] A list of liberal strings describing properties of the toolchain instances created from this variant scope. See //build/toolchain/variant_tags.gni for the list of available values and their meaning.

toolchain_args (optional) [scope] Each variable defined in this scope overrides a build argument in the toolchain context of this variant.

host_only (optional) target_only (optional) [scope] This scope can contain any of the fields above. These values are used only for host or target, respectively. Any fields included here should not also be in the outer scope.

Current value (from the default):

link_rbe_check

Run one of the more expensive checks, intended for CI. All of these require link_rbe_enable=true.

One of:

  • “none”: No additional check.

  • “determinism”: Check of determinism of linking by running locally twice and comparing outputs, failing if any differences are found. Even though this check doesn't involve RBE, it uses the same wrapper script, which knows what output files to expect and compare.

  • “consistency”: Check consistency between local and remote link actions, by running both and comparing results.

Current value (from the default): "none"

From //build/toolchain/rbe.gni:244

link_rbe_enable

Set to true to enable remote linking using RBE. This covers actions that use ar, or use clang to drive linkers like lld.

link_rbe_exec_strategy

One of:

  • “remote”: Execute action remotely on cache miss. The remote cache is always updated with this result.

  • “local”: Lookup action in the remote cache, but execute action locally on cache miss. The locally produced result is not uploaded to the remote cache.

  • “remote_local_fallback”: Execute action remotely first. If that fails, run locally instead. The locally produced results are not uploaded to the remote cache.

  • “racing”: Race local vs. remote execution, take the first to finish.

(There are other rewrapper options that are not exposed.)

Current value (from the default): "remote"

llvm_prefix

This directory contains the cipd packages for linux-x64, linux-arm64, and mac-x64. Rather than using the prebuilts provided with the source tree, you can download these individual packages from cipd and set this to the directory containing those packages.

lsan_default_options

Default LeakSanitizer options (before the LSAN_OPTIONS environment variable is read at runtime). This can be set as a build argument to affect most “lsan” variants in $variants (which see), or overridden in $toolchain_args in one of those variants. This can be a list of strings or a single string.

Note that even if this is empty, programs in this build cannot define their own __lsan_default_options C function. Instead, they can use a sanitizer_extra_options() target in their deps and then any options injected that way can override that option's setting in this list.

min_crashlog_size

Controls minimum amount of space of persistent RAM to reserve for the crashlog.

monolithic_binaries

Only for local development. When true the binaries (perfetto, traced, ...) are monolithic and don't use a common shared library. This is mainly to avoid LD_LIBRARY_PATH dances when testing locally. On Windows we default to monolithic executables, because pairing dllexport/import adds extra complexity for little benefit. The only reason for monolithic_binaries=false is saving binary size, which matters mainly on Android. See also comments on PERFETTO_EXPORT_ENTRYPOINT in compiler.h.

Current value (from the default): true

From //src/graphics/drivers/msd-arm-mali/src/BUILD.gn:13

msd_arm_enable_protected_debug_swap_mode

In protected mode, faults don‘t return as much information so they’re much harder to debug. To work around that, add a mode where protected atoms are executed in non-protected mode and vice-versa.

NOTE: The memory security ranges should also be set (in TrustZone) to the opposite of normal, so that non-protected mode accesses can only access protected memory and vice versa. Also, growable memory faults won't work in this mode, so larger portions of growable memory should precommitted (which is not done by default).

pw_toolchain_CLANG_PREFIX

This flag allows you to specify a prefix to use for clang, clang++, and llvm-ar binaries to use when compiling with a clang-based toolchain. This is useful for debugging toolchain-related issues by building with an externally-provided toolchain.

Pigweed toolchains should NOT override this variable so projects or users can control it via .gn or by setting it as a regular gn argument (e.g. gn gen --args='pw_toolchain_CLANG_PREFIX=/path/to/my-llvm-').

Examples: pw_toolchain_CLANG_PREFIX = "" command: “clang” (from PATH)

pw_toolchain_CLANG_PREFIX = “my-” command: “my-clang” (from PATH)

pw_toolchain_CLANG_PREFIX = “/bin/my-” command: “/bin/my-clang” (absolute path)

pw_toolchain_CLANG_PREFIX = “//environment/clang_next/” command: “../environment/clang_next/clang” (relative path)

GN templates should use pw_toolchain_clang_tools.* to get the intended command string rather than relying directly on pw_toolchain_CLANG_PREFIX.

If the prefix begins with “//”, it will be rebased to be relative to the root build directory.

Current value (from the default): "//prebuilt/third_party/bin/"

From //third_party/pigweed/src/pw_toolchain/clang_tools.gni:56

pw_toolchain_COVERAGE_ENABLED

Indicates if this toolchain supports generating coverage reports from pw_test targets.

For example, the static analysis toolchains that run clang-tidy instead of the test binary itself cannot generate coverage reports.

This is typically set by individual toolchains and not by GN args.

Current value (from the default): false

From //third_party/pigweed/src/pw_toolchain/host_clang/toolchains.gni:32

pw_toolchain_FUZZING_ENABLED

Indicates if this toolchain supports building fuzzers. This is typically set by individual toolchains and not by GN args.

Current value (from the default): false

From //third_party/pigweed/src/pw_toolchain/host_clang/toolchains.gni:39

pw_toolchain_OSS_FUZZ_ENABLED

Indicates if this build is a part of OSS-Fuzz, which needs to be able to provide its own compiler and flags. This violates the build hermeticisim and should only be used for OSS-Fuzz.

Current value (from the default): false

From //third_party/pigweed/src/pw_toolchain/host_clang/toolchains.gni:44

pw_toolchain_PROFILE_SOURCE_FILES

List of source files to selectively collect coverage.

Current value (from the default): []

From //third_party/pigweed/src/pw_toolchain/host_clang/toolchains.gni:35

pw_toolchain_RBE_DEBUG

Current value (from the default): false

From //third_party/pigweed/src/pw_toolchain/rbe.gni:26

pw_toolchain_RUST_PREFIX

This flag allows you to specify a prefix for rustc.

This follows the same rules as pw_toolchain_CLANG_PREFIX, see above for more information.

If the prefix begins with “//”, it will be rebased to be relative to the root build directory.

Current value (from the default): "//prebuilt/third_party/bin/"

From //third_party/pigweed/src/pw_toolchain/clang_tools.gni:65

pw_toolchain_SANITIZERS

Sets the sanitizer to pass to clang. Valid values are “address”, “memory”, “thread”, “undefined”, “undefined_heuristic”.

Current value (from the default): []

From //third_party/pigweed/src/pw_toolchain/host_clang/toolchains.gni:23

pw_toolchain_SCOPE

Scope defining the current toolchain. Contains all of the arguments required by the generate_toolchain template. This should NOT be manually modified.

Current value (from the default): { }

From //third_party/pigweed/src/pw_toolchain/generate_toolchain.gni:23

pw_toolchain_STATIC_ANALYSIS_SKIP_INCLUDE_PATHS

Disable clang-tidy for specific include paths. In the clang-tidy command, include paths that end with one of these, or match as a regular expression, are switched from -I to -isystem, which causes clang-tidy to ignore them. Unfortunately, clang-tidy provides no other way to filter header files.

For example, the following ignores header files in “repo/include”:

pw_toolchain_STATIC_ANALYSIS_SKIP_INCLUDE_PATHS = [“repo/include”]

While the following ignores all third-party header files:

pw_toolchain_STATIC_ANALYSIS_SKIP_INCLUDE_PATHS = [“./third_party/.”]

Current value (from the default): []

From //third_party/pigweed/src/pw_toolchain/static_analysis_toolchain.gni:48

pw_toolchain_STATIC_ANALYSIS_SKIP_SOURCES_RES

Regular expressions matching the paths of the source files to be excluded from the analysis. clang-tidy provides no alternative option.

For example, the following disables clang-tidy on all source files in the third_party directory:

pw_toolchain_STATIC_ANALYSIS_SKIP_SOURCES_RES = [“third_party/.*”]

Current value (from the default): []

From //third_party/pigweed/src/pw_toolchain/static_analysis_toolchain.gni:33

Current value (from the default): false

From //third_party/pigweed/src/pw_toolchain/rbe.gni:20

pw_unit_test_AUTOMATIC_RUNNER

Path to a test runner to automatically run unit tests after they are built.

If set, a pw_test target‘s <target_name>.run action will invoke the test runner specified by this argument, passing the path to the unit test to run. If this is unset, the pw_test target’s <target_name>.run step will do nothing.

Targets that don't support parallelized execution of tests (e.g. a on-device test runner that must flash a device and run the test in serial) should set pw_unit_test_POOL_DEPTH to 1.

Type: string (name of an executable on the PATH, or path to an executable) Usage: toolchain-controlled only

Current value (from the default): ""

From //third_party/pigweed/src/pw_unit_test/test.gni:63

pw_unit_test_AUTOMATIC_RUNNER_ARGS

Current value (from the default): []

From //third_party/pigweed/src/pw_unit_test/test.gni:69

pw_unit_test_AUTOMATIC_RUNNER_TIMEOUT

Optional timeout to apply when running tests via the automatic runner. Timeout is in seconds. Defaults to empty which means no timeout.

Current value (from the default): ""

From //third_party/pigweed/src/pw_unit_test/test.gni:73

pw_unit_test_BACKEND

The unit test framework implementation. Defaults to pw_unit_test:light, which implements a subset of GoogleTest safe to run on device. Set to //pw_unit_test:googletest when using GoogleTest.

Current value (from the default): "pw_executable"

From //third_party/pigweed/src/pw_unit_test/test.gni:102

pw_unit_test_EXECUTABLE_TARGET_TYPE_FILE

The path to the .gni file that defines pw_unit_test_EXECUTABLE_TARGET_TYPE.

If pw_unit_test_EXECUTABLE_TARGET_TYPE is not the default of pw_executable, this .gni file is imported to provide the template definition.

pw_unit_test_GOOGLETEST_BACKEND

The GoogleTest library target. This is not a pw_unit_test backend (anymore). Use this to depend on the GoogleTest library directly WITHOUT using the pw_unit_test facade. The //pw_unit_test:googletest backend depends on this library target. Defaults to //third_party/googletest.

pw_unit_test_POOL_DEPTH

The maximum number of unit tests that may be run concurrently for the current toolchain. Setting this to 0 disables usage of a pool, allowing unlimited parallelization.

Note: A single target with two toolchain configurations (e.g. release/debug) will use two separate test runner pools by default. Set pw_unit_test_POOL_TOOLCHAIN to the same toolchain for both targets to merge the pools and force serialization.

Type: integer Usage: toolchain-controlled only

Current value (from the default): 0

From //third_party/pigweed/src/pw_unit_test/test.gni:86

pw_unit_test_POOL_TOOLCHAIN

The toolchain to use when referring to the pw_unit_test runner pool. When this is disabled, the current toolchain is used. This means that every toolchain will use its own pool definition. If two toolchains should share the same pool, this argument should be by one of the toolchains to the GN path of the other toolchain.

Type: string (GN path to a toolchain) Usage: toolchain-controlled only

Current value (from the default): ""

From //third_party/pigweed/src/pw_unit_test/test.gni:96

pw_unit_test_TESTONLY

qemu_boot_format

Boot format to use with QEMU. This chooses the boot format to use with QEMU, determining which boot shim implementation is used as QEMU “kernel”. Valid alternatives vary by machine, but include “linuxboot”.

Current value (from the default): "linuxboot"

qr_codes_path

Current value (from the default): "//src/recovery/system/res/qr_codes.riv"

From //src/recovery/system/system_recovery_args.gni:11

recovery_label

Allows a product to specify the recovery image used in the zirconr slot. Default recovery image is zedboot. Overriding this value will keep zedboot in the build but will not include it as the default zirconr image. Recovery images can provide an update target by specifying the metadata item “update_target” in the format =. (Such as update_target = [ "recovery=" + rebase_path(recovery_path, root_build_dir) ]) Example value: “//build/images/recovery”

recovery_only

This is really a build for a recovery image, and so the fuchsia image that is being built isn‘t properly configured, and so just disable the new image assembly work until that’s been addressed.

repository_publish_blob_copy_mode

Controls which mode to use when copying blobs into the repository. Supported modes are:

  • copy: copy the blob if the blob does not already exist in the repository. This will use copy-on-write to efficiently copy the blob on file systems that support it.

  • copy-overwrite: always copy the blob, overwriting any blob that exists in the blob repository. This will use copy-on-write to efficiently copy the blob on file systems that support it.

  • hard-link: hard link the blob into the repository, or copy if we cannot create a hard link between the blob and the blob repository. Note that it is possible to modify the blob through the hard link, which would result in the blob not matching the blob's merkle.

Current value (from the default): "hard-link"

From //src/sys/pkg/bin/package-tool/package-tool.gni:287

restat_cc

Set to true to make C++ compiles preserve timestamps of unchanged outputs. re-client provides this feature out-of-the-box with --preserve_unchanged_output_mtime, so it makes sense to default to true when using cxx_rbe_enable. When not using re-client, you can still get write-if-change behavior through the restat_wrapper script, but at the cost of the wrapper overhead (tradeoff vs. action pruning).

Current value (from the default): false

rust_cap_lints

Sets the maximum lint level. “deny” will make all warnings into errors, “warn” preserves them as warnings, and “allow” will ignore warnings.

Current value (from the default): "deny"

From //build/rust/config.gni:55

rust_debug_assertions

Enable debug assertions, e.g. for overflow checking.

Current value (from the default): false

From //build/config/rust/BUILD.gn:33

rust_emit_rmeta

Set to true to emit additional .rmeta files when compiling Rust rlibs. The .rmeta metadata files can be used by downstream build actions to quickly evaluate transitive dependencies (and remote inputs).

Current value (from the default): false

From //build/toolchain/rbe.gni:126

rust_incremental

Enable incremental rust compilation. Takes a path to the directory to use as the cache.

Current value (from the default): ""

rust_lto

Sets the default LTO type for rustc builds.

Current value (from the default): ""

From //build/rust/config.gni:47

rust_one_rlib_per_dir

To avoid build nondeterminism due to extern search paths resolving to more than one path during a build, enable this option to place every rlib into its own exclusive directory. This requires rustc_use_response_file = true due to the command-line bloat this causes. See http://g-issues.fuchsia.dev/issues/319148874 for more details.

Current value (from the default): false

From //build/rust/build.gni:19

rust_rbe_check

Run one of the more expensive checks, intended for CI. All of these require rust_rbe_enable=true.

One of:

  • “none”: No additional check.

  • “determinism”: Check of determinism of rustc targets by running locally twice and comparing outputs, failing if any differences are found. Even though this check doesn't involve RBE, it uses the same wrapper script, which knows what output files to expect and compare.

    Build outputs that depend on time are discouraged because they impact caching. If your result depends on the current time, this check will definitely fail. If it depends on only the date, there is still a nonzero chance of failure, if the rerun falls on the next day.

  • “consistency”: Check consistency between local and remote rust compiles, by running both and comparing results.

Current value (from the default): "none"

From //build/toolchain/rbe.gni:114

rust_rbe_download_rlibs

rust_rbe_download_unstripped_binaries

Controls whether or not to download (often large) unstripped Rust binaries. When downloading is disabled, the build produces stubs that be used to retrieve remote artifacts later using build/rbe/dlwrap.py. TODO(b/284994230): This option is only available to developers, and not restricted environments that lack direct network access.

Current value (from the default): true

rust_rbe_exec_strategy

One of:

  • “remote”: Execute action remotely on cache miss. The remote cache is always updated with this result.

  • “local”: Lookup action in the remote cache, but execute action locally on cache miss. The locally produced result is not uploaded to the remote cache.

  • “remote_local_fallback”: Execute action remotely first. If that fails, run locally instead. The locally produced results are not uploaded to the remote cache.

  • “racing”: Race local vs. remote execution, take the first to finish.

(There are other rewrapper options that are not exposed.)

Current value (from the default): "remote"

Current value (from the default): "//prebuilt/third_party/rust/linux-x64"

From //build/rust/config.gni:19

rustc_use_response_files

Place lengthy rustdeps and externs (GN) into ninja response files. Response files are needed to get around command line length limitations. rustc support for response files (as needed in our GN build) was added with revision ‘git_revision:dfe53afaebd817f334d8ef9dc75a5cd2562cf6e6’. This optional will eventually become permanently true.

Current value (from the default): false

rustc_version_description

Human-readable identifier for the toolchain version.

Current value (from the default): ""

From //build/rust/config.gni:44

rustc_version_string

This is a string identifying the particular toolchain version in use. Its only purpose is to be unique enough that it changes when switching to a new toolchain, so that recompilations with the new compiler can be triggered.

When using the prebuilt, this is ignored and the CIPD instance ID of the prebuilt is used.

Current value (from the default): "UTqyxcD4n3nCoqodkYrlANhYywikk4TKAhxkbPhQTYIC"

scenic_enable_vulkan_validation

scheduler_extra_invariant_validation

Enables extra (expensive) validation of scheduler invariants to assist in debugging changes to the scheduler's behavior.

Current value (from the default): false

From //zircon/kernel/params.gni:60

scheduler_lock_spin_tracing_compressed

Enables compressed records when tracing lock-spin events. The events will be more difficult to interpret in a trace visualizer, but will take less space and provide the same information to scripts which parse lock trace data.

Current value (from the default): false

From //zircon/kernel/params.gni:70

scheduler_lock_spin_tracing_enabled

Enables scheduler lock-spinning trace events for trace-based scheduler performance analysis.

Current value (from the default): false

scheduler_queue_tracing_enabled

Enables scheduler queue tracing for trace-based scheduler performance analysis.

Current value (from the default): false

From //zircon/kernel/params.gni:56

scheduler_tracing_level

The level of detail for scheduler traces when enabled. Values greater than zero add increasing details at the cost of increased trace buffer use.

0 = Default kernel:sched tracing. 1 = Adds duration traces for key scheduler operations. 2 = Adds flow events from wakeup to running state. 3 = Adds detailed internal durations and probes.

Current value (from the default): 0

From //zircon/kernel/params.gni:52

scudo_default_options

Default Scudo options (before the SCUDO_OPTIONS environment variable is read at runtime). Scudo is the memory allocator in Fuchsia's C library, so this affects all Fuchsia programs. This can be a list of strings or a single string.

This operates similarly to asan_default_options and its cousins for other sanitizers, but is slightly different. If this variable is empty, then no __scudo_default_options function is injected into programs at all. Individual targets can use dependencies on sanitizer_extra_options() targets to cause options to be injected, and that will be compatible with any build-wide settings of scudo_default_options. Programs can define their own __scudo_default_options functions, but doing so will break all builds with this variable is set to nonempty, so any program in the build that needs such a setting (which should be only in tests) can use the sanitizer_extra_options() mechanism instead.

Current value (from the default): []

From //build/config/sanitizers/sanitizer_default_options.gni:82

sdk_archive_labels

sdk_cross_compile_host_tools

Whether to cross-compile SDK tools for all supported host toolchains, rather than just the current host toolchains. For example, if this is true then for instance if building on linux x64 then you'll also build SDK host tools for linux arm64.

Current value (from the default): false

sdk_inside_sub_build

Whether currently building a sub-build (vs. the main build). Can be true for any API level, including the default level.

Current value (from the default): false

From //build/sdk/config.gni:12

sdk_inside_supported_api_sub_build

Whether currently building a sub-build for a specific supported API level rather than a build or sub-build at the default API level. Note that this can be false in sub-builds - specifically, when building the default API level for target CPUs other than the host. sdk_inside_sub_build must be true and override_target_api_level must be set to a valid level.

Current value (from the default): false

From //build/sdk/config.gni:20

sdk_max_simultaneous_sub_builds

An upper bound on the maximum number of subbuilds that may be running at the same time. A larger number means these good things:

  • Better parallelization of the inherently single-threaded parts of GN and ninja.
  • Better parallelization in the face of “stragglers” in the build - situations where each subbuild is executing a small number of actions.

But also these bad things:

  • More memory usage, potentially leading to swapping and slowdowns.
  • More CPU contention when the build process is actually CPU-bound.
  • Potentially forcing a lower value of sdk_sub_build_parallelism, since the total load is proportional to sdk_max_simultaneous_sub_builds * sdk_sub_build_parallelism.

5 was chosen mostly because it's the number of fingers on each of my hands.

Current value (from the default): 5

From //build/sdk/config.gni:37

sdk_sub_build_max_load_average

Value of -l to pass to ninja during a subbuild. If the system load average on the system goes beyond this value, ninja will throttle itself. If left blank, the subbuild script will make a guess.

Current value (from the default): ""

From //build/sdk/config.gni:49

sdk_sub_build_parallelism

Value of -j to pass to ninja during a subbuild. Note that up to sdk_max_simultaneous_sub_builds subbuilds may be happening in parallel, so the number of concurrent actions may go as high as this number times the number of concurrent subbuilds. If left blank, the subbuild script will make a guess.

Current value (from the default): ""

From //build/sdk/config.gni:44

select_variant

List of “selectors” to request variant builds of certain targets. Each selector specifies matching criteria and a chosen variant. The first selector in the list to match a given target determines which variant is used for that target.

Each selector is either a string or a scope. A shortcut selector is a string; it gets expanded to a full selector. A full selector is a scope, described below.

A string selector can match a name in select_variant_shortcuts. If it‘s not a specific shortcut listed there, then it can be the name of any variant described in known_variants and universal_variants (and combinations thereof). A selector that’s a simple variant name selects for every binary built in the target toolchain: { host=false variant=selector }.

If a string selector contains a slash, then it‘s "shortcut/filename" and selects only the binary in the target toolchain whose output_name matches "filename", i.e. it adds output_name=["filename"] to each selector scope that the shortcut’s name alone would yield.

The scope that forms a full selector defines some of these:

variant (required)
    [string or `false`] The variant that applies if this selector
    matches.  This can be `false` to choose no variant, or a string
    that names the variant.  See
    [`known_variants`](#known_variants) and
    [`universal_variants`](#universal_variants).

The rest below are matching criteria. All are optional. The selector matches if and only if all of its criteria match. If none of these is defined, then the selector always matches.

The first selector in the list to match wins and then the rest of the list is ignored. To construct more complex rules, use a blocklist selector with variant=false before a catch-all default variant, or a list of specific variants before a catch-all false variant.

Each “[strings]” criterion is a list of strings, and the criterion is satisfied if any of the strings matches against the candidate string.

host
    [boolean] If true, the selector matches in the host toolchain.
    If false, the selector matches in the target toolchain.

testonly
    [boolean] If true, the selector matches targets with testonly=true.
    If false, the selector matches in targets without testonly=true.

target_type
    [strings]: `"executable"`, `"loadable_module"`, or `"fuchsia_driver"`

output_name
    [strings]: target's `output_name` (default: its `target name`)

label
    [strings]: target's full label with `:` (without toolchain suffix)

name
    [strings]: target's simple name (label after last `/` or `:`)

dir
    [strings]: target's label directory (`//dir` for `//dir:name`).

Current value (from the default): []

From //build/config/BUILDCONFIG.gn:2089

select_variant_canonical

This should never be set as a build argument. It exists only to be set in toolchain_args. See //build/toolchain/clang_toolchain.gni for details.

Current value (from the default): []

From //build/config/BUILDCONFIG.gn:2094

select_variant_shortcuts

List of short names for commonly-used variant selectors. Normally this is not set as a build argument, but it serves to document the available set of short-cut names for variant selectors. Each element of this list is a scope where .name is the short name and .select_variant is a a list that can be spliced into select_variant.

Current value (from the default):

[{
  name = "host_asan"
  select_variant = [{
  host = true
  variant = "asan"
}]
}, {
  name = "host_asan-ubsan"
  select_variant = [{
  host = true

size_checker_input

The input to the size checker. The build system will produce a JSON file to be consumed by the size checker, which will check and prevent integration of subsystems that are over their space allocation. The input consists of the following keys:

asset_ext(string array): a list of extensions that should be considered as assets.

asset_limit(number): maximum size (in bytes) allocated for the assets.

core_limit(number): maximum size (in bytes) allocated for the core system and/or services. This is sort of a “catch all” component that consists of all the area / packages that weren't specified in the components list below.

core_creep_limit(number): maximum size creep (in bytes) per-CL allocated for the core system and/or services. This may be enforced by Gerrit.

components(object array): a list of component objects. Each object should contain the following keys:

component(string): name of the component.

src(string array): path of the area / package to be included as part of the component. The path should be relative to the obj/ in the output directory. For example, consider two packages foo and far, built to out/.../obj/some_big_component/foo and out/.../obj/some_big_component/bar. If you want to impose a limit on foo, your src will be [“some_big_component/foo”]. If you want to impose a limit on both foo and far, your src will be [“some_big_component”]. If a package has config-data, those prebuilt blobs actually live under the config-data package. If you wish to impose a limit of those data as well, you should add “build/images/config-data/$for_pkg” to your src. The $for_pkg corresponds to the $for_pkg field in config.gni.

limit(number): maximum size (in bytes) allocated for the component. creep_limit(number): maxmium size creep (in bytes) per-CL allocated for the component. This may be enforced by Gerrit.

distributed_shlibs(string array): a list of shared libraries which are distributed in the Fuchsia SDK for partners to use in their prebuilt packages.

distributed_shlibs_limit(number): maximum size (in bytes) allocated for distributed shared libraries.

distributed_shlibs_creep_limit(number): maximum size creep (in bytes) allocated for distributed shared libraries. This may be enforced by Gerrit.

icu_data(string array): a list of files which contribute to the ICU data limit.

icu_data_limit(number): maximum size (in bytes) allocated to ICU data files.

icu_data_creep_limit(number): maximum size creep (in bytes) allocated to ICU data files. This may be enforced by Gerrit.

Example: size_checker_input = { asset_ext = [ “.ttf” ] asset_limit = 10240 core_limit = 10240 core_creep_limit = 320 distributed_shlibs = [ “lib/ld.so.1”, “lib/libc++.so.2”, ] distributed_shlibs_limit = 10240 distributed_shlibs_creep_limit = 320 icu_data = [ “icudtl.dat” ] icu_data_limit = 20480 icu_data_creep_limit = 320 components = [ { component = “Foo” src = [ “topaz/runtime/foo_runner” ] limit = 10240 creep_limit = 320 }, { component = “Bar” src = [ “build/images” ] limit = 20480 creep_limit = 640 }, ] }

Note that even if this is empty, programs in this build cannot define their own __tsan_default_options C function. Instead, they can use a sanitizer_extra_options() target in their deps and then any options injected that way can override that option's setting in this list.

TODO(https://fxbug.dev/42171381): ignore_noninstrumented_modules=1 can be reevaluated when/if we have an instrumented libstd for Rust.

use_prebuilt_ffmpeg

Use a prebuilt ffmpeg binary rather than building it locally. See //src/media/lib/ffmpeg/README.md for details. This is ignored when building in variant builds for which there is no prebuilt. In that case, ffmpeg is always built from source so as to be built with the selected variant's config. When this is false (either explicitly or in a variant build) then //third_party/ffmpeg must be in the source tree, which requires:

TODO(https://fxbug.dev/42068172): This isn't currently working. Use the method below.

Or, if already importing a different manifest from there, resulting in errors from jiri update, it can work to just git clone (but jiri update won't manage third_party/ffmpeg in this case):
