After this change, the dependency hierachy can be arbitrarily deep. For example, you can have one boot image that extends another boot image that extends yet another boot image. Bug: 269230245 Test: m Change-Id: I096d0b57bda36b982ecc97378647f9c59071a3bf

// WIP - see http://b/177892522 for details

|
//
|
|
// The build support for boot images is currently being migrated away from singleton to modules so
|
|
// the documentation may not be strictly accurate. Rather than update the documentation at every
|
|
// step which will create a lot of churn the changes that have been made will be listed here and the
|
|
// documentation will be updated once it is closer to the final result.
|
|
//
|
|
// Changes:
|
|
// 1) dex_bootjars is now a singleton module and not a plain singleton.
|
|
// 2) Boot images are now represented by the boot_image module type.
|
|
// 3) The art boot image is called "art-boot-image", the framework boot image is called
|
|
// "framework-boot-image".
|
|
// 4) They are defined in art/build/boot/Android.bp and frameworks/base/boot/Android.bp
|
|
// respectively.
|
|
// 5) Each boot_image retrieves the appropriate boot image configuration from the map returned by
|
|
// genBootImageConfigs() using the image_name specified in the boot_image module.

// 1. ART boot images in general (their types, structure, file layout, etc.)
|
|
// 2. build system support for boot images
|
|
//
|
|
// 1. ART boot images
|
|
// ------------------
|
|
//
|
|
// A boot image in ART is a set of files that contain AOT-compiled native code and a heap snapshot
|
|
// of AOT-initialized classes for the bootclasspath Java libraries. A boot image is compiled from a
|
|
// set of DEX jars by the dex2oat compiler. A boot image is used for two purposes: 1) it is
|
|
// installed on device and loaded at runtime, and 2) other Java libraries and apps are compiled
|
|
// against it (compilation may take place either on host, known as "dexpreopt", or on device, known
|
|
// as "dexopt").
|
|
//
|
|
// A boot image is not a single file, but a collection of interrelated files. Each boot image has a
|
|
// number of components that correspond to the Java libraries that constitute it. For each component
|
|
// there are multiple files:
|
|
// - *.oat or *.odex file with native code (architecture-specific, one per instruction set)
|
|
// - *.art file with pre-initialized Java classes (architecture-specific, one per instruction set)
|
|
// - *.vdex file with verification metadata for the DEX bytecode (architecture independent)
|
|
//
|
|
// *.vdex files for the boot images do not contain the DEX bytecode itself, because the
|
|
// bootclasspath DEX files are stored on disk in uncompressed and aligned form. Consequently a boot
|
|
// image is not self-contained and cannot be used without its DEX files. To simplify the management
|
|
// of boot image files, ART uses a certain naming scheme and associates the following metadata with
|
|
// each boot image:
|
|
// - A stem, which is a symbolic name that is prepended to boot image file names.
|
|
// - A location (on-device path to the boot image files).
|
|
// - A list of boot image locations (on-device paths to dependency boot images).
|
|
// - A set of DEX locations (on-device paths to the DEX files, one location for one DEX file used
|
|
// to compile the boot image).
|
|
//
|
|
// There are two kinds of boot images:
|
|
// - primary boot images
|
|
// - boot image extensions
|
|
//
|
|
// 1.1. Primary boot images
|
|
// ------------------------
|
|
//
|
|
// A primary boot image is compiled for a core subset of bootclasspath Java libraries. It does not
|
|
// depend on any other images, and other boot images may depend on it.
|
|
//
|
|
// For example, assuming that the stem is "boot", the location is /apex/com.android.art/javalib/,
|
|
// the set of core bootclasspath libraries is A B C, and the boot image is compiled for ARM targets
|
|
// (32 and 64 bits), it will have three components with the following files:
|
|
// - /apex/com.android.art/javalib/{arm,arm64}/boot.{art,oat,vdex}
|
|
// - /apex/com.android.art/javalib/{arm,arm64}/boot-B.{art,oat,vdex}
|
|
// - /apex/com.android.art/javalib/{arm,arm64}/boot-C.{art,oat,vdex}
|
|
//
|
|
// The files of the first component are special: they do not have the component name appended after
|
|
// the stem. This naming convention dates back to the times when the boot image was not split into
|
|
// components, and there were just boot.oat and boot.art. The decision to split was motivated by
|
|
// licensing reasons for one of the bootclasspath libraries.
|
|
//
|
|
// As of November 2020 the only primary boot image in Android is the image in the ART APEX
|
|
// com.android.art. The primary ART boot image contains the Core libraries that are part of the ART
|
|
// module. When the ART module gets updated, the primary boot image will be updated with it, and all
|
|
// dependent images will get invalidated (the checksum of the primary image stored in dependent
|
|
// images will not match), unless they are updated in sync with the ART module.
|
|
//
|
|
// 1.2. Boot image extensions
|
|
// --------------------------
|
|
//
|
|
// A boot image extension is compiled for a subset of bootclasspath Java libraries (in particular,
|
|
// this subset does not include the Core bootclasspath libraries that go into the primary boot
|
|
// image). A boot image extension depends on the primary boot image and optionally some other boot
|
|
// image extensions. Other images may depend on it. In other words, boot image extensions can form
|
|
// acyclic dependency graphs.
|
|
//
|
|
// The motivation for boot image extensions comes from the Mainline project. Consider a situation
|
|
// when the list of bootclasspath libraries is A B C, and both A and B are parts of the Android
|
|
// platform, but C is part of an updatable APEX com.android.C. When the APEX is updated, the Java
|
|
// code for C might have changed compared to the code that was used to compile the boot image.
|
|
// Consequently, the whole boot image is obsolete and invalidated (even though the code for A and B
|
|
// that does not depend on C is up to date). To avoid this, the original monolithic boot image is
|
|
// split in two parts: the primary boot image that contains A B, and the boot image extension that
|
|
// contains C and depends on the primary boot image (extends it).
|
|
//
|
|
// For example, assuming that the stem is "boot", the location is /system/framework, the set of
|
|
// bootclasspath libraries is D E (where D is part of the platform and is located in
|
|
// /system/framework, and E is part of a non-updatable APEX com.android.E and is located in
|
|
// /apex/com.android.E/javalib), and the boot image is compiled for ARM targets (32 and 64 bits),
|
|
// it will have two components with the following files:
|
|
// - /system/framework/{arm,arm64}/boot-D.{art,oat,vdex}
|
|
// - /system/framework/{arm,arm64}/boot-E.{art,oat,vdex}
|
|
//
|
|
// As of November 2020 the only boot image extension in Android is the Framework boot image
|
|
// extension. It extends the primary ART boot image and contains Framework libraries and other
|
|
// bootclasspath libraries from the platform and non-updatable APEXes that are not included in the
|
|
// ART image. The Framework boot image extension is updated together with the platform. In the
|
|
// future other boot image extensions may be added for some updatable modules.
|
|
//
|
|
//
|
|
// 2. Build system support for boot images
|
|
// ---------------------------------------
|
|
//
|
|
// The primary ART boot image needs to be compiled with one dex2oat invocation that depends on DEX
|
|
// jars for the core libraries. Framework boot image extension needs to be compiled with one dex2oat
|
|
// invocation that depends on the primary ART boot image and all bootclasspath DEX jars except the
|
|
// core libraries as they are already part of the primary ART boot image.
|
|
//
|
|
// 2.1. Libraries that go in the boot images
|
|
// -----------------------------------------
|
|
//
|
|
// The contents of each boot image are determined by the PRODUCT variables. The primary ART APEX
|
|
// boot image contains libraries listed in the ART_APEX_JARS variable in the AOSP makefiles. The
|
|
// Framework boot image extension contains libraries specified in the PRODUCT_BOOT_JARS and
|
|
// PRODUCT_BOOT_JARS_EXTRA variables. The AOSP makefiles specify some common Framework libraries,
|
|
// but more product-specific libraries can be added in the product makefiles.
|
|
//
|
|
// Each component of the PRODUCT_BOOT_JARS and PRODUCT_BOOT_JARS_EXTRA variables is a
|
|
// colon-separated pair <apex>:<library>, where <apex> is the variant name of a non-updatable APEX,
|
|
// "platform" if the library is a part of the platform in the system partition, or "system_ext" if
|
|
// it's in the system_ext partition.
|
|
//
|
|
// In these variables APEXes are identified by their "variant names", i.e. the names they get
|
|
// mounted as in /apex on device. In Soong modules that is the name set in the "apex_name"
|
|
// properties, which default to the "name" values. For example, many APEXes have both
|
|
// com.android.xxx and com.google.android.xxx modules in Soong, but take the same place
|
|
// /apex/com.android.xxx at runtime. In these cases the variant name is always com.android.xxx,
|
|
// regardless which APEX goes into the product. See also android.ApexInfo.ApexVariationName and
|
|
// apex.apexBundleProperties.Apex_name.
|
|
//
|
|
// A related variable PRODUCT_APEX_BOOT_JARS contains bootclasspath libraries that are in APEXes.
|
|
// They are not included in the boot image. The only exception here are ART jars and core-icu4j.jar
|
|
// that have been historically part of the boot image and are now in apexes; they are in boot images
|
|
// and core-icu4j.jar is generally treated as being part of PRODUCT_BOOT_JARS.
|
|
//
|
|
// One exception to the above rules are "coverage" builds (a special build flavor which requires
|
|
// setting environment variable EMMA_INSTRUMENT_FRAMEWORK=true). In coverage builds the Java code in
|
|
// boot image libraries is instrumented, which means that the instrumentation library (jacocoagent)
|
|
// needs to be added to the list of bootclasspath DEX jars.
|
|
//
|
|
// In general, there is a requirement that the source code for a boot image library must be
|
|
// available at build time (e.g. it cannot be a stub that has a separate implementation library).
|
|
//
|
|
// 2.2. Static configs
|
|
// -------------------
|
|
//
|
|
// Because boot images are used to dexpreopt other Java modules, the paths to boot image files must
|
|
// be known by the time dexpreopt build rules for the dependent modules are generated. Boot image
|
|
// configs are constructed very early during the build, before build rule generation. The configs
|
|
// provide predefined paths to boot image files (these paths depend only on static build
|
|
// configuration, such as PRODUCT variables, and use hard-coded directory names).
|
|
//
|
|
// 2.3. Singleton
|
|
// --------------
|
|
//
|
|
// Build rules for the boot images are generated with a Soong singleton. Because a singleton has no
|
|
// dependencies on other modules, it has to find the modules for the DEX jars using VisitAllModules.
|
|
// Soong loops through all modules and compares each module against a list of bootclasspath library
|
|
// names. Then it generates build rules that copy DEX jars from their intermediate module-specific
|
|
// locations to the hard-coded locations predefined in the boot image configs.
|
|
//
|
|
// It would be possible to use a module with proper dependencies instead, but that would require
|
|
// changes in the way Soong generates variables for Make: a singleton can use one MakeVars() method
|
|
// that writes variables to out/soong/make_vars-*.mk, which is included early by the main makefile,
|
|
// but module(s) would have to use out/soong/Android-*.mk which has a group of LOCAL_* variables
|
|
// for each module, and is included later.
|
|
//
|
|
// 2.4. Install rules
|
|
// ------------------
|
|
//
|
|
// The primary boot image and the Framework extension are installed in different ways. The primary
|
|
// boot image is part of the ART APEX: it is copied into the APEX intermediate files, packaged
|
|
// together with other APEX contents, extracted and mounted on device. The Framework boot image
|
|
// extension is installed by the rules defined in makefiles (make/core/dex_preopt_libart.mk). Soong
|
|
// writes out a few DEXPREOPT_IMAGE_* variables for Make; these variables contain boot image names,
|
|
// paths and so on.
