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.

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

Current value (from the default): false
From //build/images/fvm.gni:86
Current value (from the default): false
From //build/images/fvm.gni:88
The max size of the disk where the FVM is written. This is used for
preallocating metadata to determine how much the FVM can expand on disk.
Only applies to sparse FVM images. At sparse image construction time, the
build fails if the inputs are larger than fvm_max_disk_size. At paving
time, the FVM will be sized to the target's disk size up to
fvm_max_disk_size. If the size of the disk increases after initial paving,
the FVM will resize up to fvm_max_disk_size. During paving, if the target
FVM has declared a smaller size than fvm_max_disk_size, the FVM is
reinitialized to the larger size.
The default value is false which sets the max disk size to the size of the disk
at pave/format time.

From //build/images/fvm.gni:36
The size of the FVM partition images "slice size". The FVM slice size is a minimum size of a particular chunk of a partition that is stored within FVM. A very small slice size may lead to decreased throughput. A very large slice size may lead to wasted space. The selected default size of 8mb is selected for conservation of space, rather than performance.

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.

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

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).

- Apply SWD policies in product definitions alongside the existing SWD targets configuration. Assert that product configuration has not changed.

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.

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.

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`).

List of short names for commonly-used variant selectors. Normally this

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.

Arguments to fx flash script (along with any firmware_prebuilts which
specify a partition).
If fvm_partition is provided, the flash script will flash the full OS,
recovery + Zircon + FVM + SSH keys. In this case, the bootloader must also
support fastboot oem add-staged-bootloader-file ssh.authorized_keys.
Otherwise, the script will flash the recovery image to all slots, which doesn't require the FVM or SSH keys.

Zircon optimization level. Same acceptable values as optimize.
Note that this will be ignored, in favor of the global optimize variable
if the latter is one of: "none", "sanitizer", or "profile".
"Default" optimization offers a good balance of size and speed, as measured by size comparisons of release builds and extensive microbenchmarks. See: https://fuchsia-review.googlesource.com/c/fuchsia/+/600221/comments/3a4855ec_cf46619c

This should never be set as a build argument.
It exists only to be set in toolchain_args.
For Zircon toolchains, this will be a scope whose schema
is documented in //build/toolchain/zircon/zircon_toolchain.gni.
For all other toolchains, this will be false.
This allows testing for a Zircon-specific toolchain with:
if (zircon_toolchain != false) { // code path for Zircon-specific toolchains } else { // code path for non-Zircon ones. }
Current value (from the default): false

TODO(fxbug.dev/32255): This is a temporary switch that will be removed.
Set this to make the ZBI compatible with older boot loaders such as a gigaboot or zedboot image already installed on a machine that's hard to update. This is an interim workaround only for people who have machines that are not physically accessible to update their boot images, and will be removed after everyone has had a chance to get hold of their machines.
