-# The output of this class behaves similar to how kernel-devicetree.bbclass

-# Packaging process
-#
-# Executive summary: This class iterates over the functions listed in PACKAGEFUNCS
-# Taking D and splitting it up into the packages listed in PACKAGES, placing the
-# resulting output in PKGDEST.
-#
-# There are the following default steps but PACKAGEFUNCS can be extended:
-#
-# a) package_convert_pr_autoinc - convert AUTOINC in PKGV to ${PRSERV_PV_AUTOINC}
-#
-# b) perform_packagecopy - Copy D into PKGD
-#
-# c) package_do_split_locales - Split out the locale files, updates FILES and PACKAGES
-#
-# d) split_and_strip_files - split the files into runtime and debug and strip them.
-#    Debug files include debug info split, and associated sources that end up in -dbg packages
-#
-# e) fixup_perms - Fix up permissions in the package before we split it.
-#
-# f) populate_packages - Split the files in PKGD into separate packages in PKGDEST/<pkgname>
-#    Also triggers the binary stripping code to put files in -dbg packages.
-#
-# g) package_do_filedeps - Collect perfile run-time dependency metadata
-#    The data is stores in FILER{PROVIDES,DEPENDS}_file_pkg variables with
-#    a list of affected files in FILER{PROVIDES,DEPENDS}FLIST_pkg
-#
-# h) package_do_shlibs - Look at the shared libraries generated and autotmatically add any
-#    dependencies found. Also stores the package name so anyone else using this library
-#    knows which package to depend on.
-#
-# i) package_do_pkgconfig - Keep track of which packages need and provide which .pc files
-#
-# j) read_shlibdeps - Reads the stored shlibs information into the metadata
-#
-# k) package_depchains - Adds automatic dependencies to -dbg and -dev packages
-#
-# l) emit_pkgdata - saves the packaging data into PKGDATA_DIR for use in later
-#    packaging steps

-# Help runqemu boot target board, "QB" means Qemu Boot, the following
-# vars can be set in conf files, such as <bsp.conf> to make it can be
-# boot by runqemu:
-#
-# QB_SYSTEM_NAME: qemu name, e.g., "qemu-system-i386"
-#
-# QB_OPT_APPEND: options to append to qemu, e.g., "-device usb-mouse"
-#
-# QB_DEFAULT_KERNEL: default kernel to boot, e.g., "bzImage"
-#
-# QB_DEFAULT_FSTYPE: default FSTYPE to boot, e.g., "ext4"
-#
-# QB_MEM: memory, e.g., "-m 512"
-#
-# QB_MACHINE: qemu machine, e.g., "-machine virt"
-#
-# QB_CPU: qemu cpu, e.g., "-cpu qemu32"
-#
-# QB_CPU_KVM: the similar to QB_CPU, but used when kvm, e.g., '-cpu kvm64',
-#             set it when support kvm.
-#
-# QB_SMP: amount of CPU cores inside qemu guest, each mapped to a thread on the host,
-#             e.g. "-smp 8".
-#
-# QB_KERNEL_CMDLINE_APPEND: options to append to kernel's -append
-#                           option, e.g., "console=ttyS0 console=tty"
-#
-# QB_DTB: qemu dtb name
-#
-# QB_AUDIO_DRV: qemu audio driver, e.g., "alsa", set it when support audio
-#
-# QB_AUDIO_OPT: qemu audio option, e.g., "-device AC97", used
-#               when QB_AUDIO_DRV is set.
-#
-# QB_RNG: Pass-through for host random number generator, it can speedup boot
-#         in system mode, where system is experiencing entropy starvation
-#
-# QB_KERNEL_ROOT: kernel's root, e.g., /dev/vda
-#                 By default "/dev/vda rw" gets passed to the kernel.
-#                 To mount the rootfs read-only QB_KERNEL_ROOT can be set to e.g. "/dev/vda ro".
-#
-# QB_NETWORK_DEVICE: network device, e.g., "-device virtio-net-pci,netdev=net0,mac=@MAC@",
-#                    it needs work with QB_TAP_OPT and QB_SLIRP_OPT.
-#                    Note, runqemu will replace @MAC@ with a predefined mac, you can set
-#                    a custom one, but that may cause conflicts when multiple qemus are
-#                    running on the same host.
-#                    Note: If more than one interface of type -device virtio-net-device gets added,
-#                          QB_NETWORK_DEVICE:prepend might be used, since Qemu enumerates the eth*
-#                          devices in reverse order to -device arguments.
-#
-# QB_TAP_OPT: network option for 'tap' mode, e.g.,
-#             "-netdev tap,id=net0,ifname=@TAP@,script=no,downscript=no"
-#              Note, runqemu will replace "@TAP@" with the one which is used, such as tap0, tap1 ...
-#
-# QB_SLIRP_OPT: network option for SLIRP mode, e.g., -netdev user,id=net0"
-#
-# QB_CMDLINE_IP_SLIRP: If QB_NETWORK_DEVICE adds more than one network interface to qemu, usually the
-#                      ip= kernel comand line argument needs to be changed accordingly. Details are documented
-#                      in the kernel docuemntation https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
-#                      Example to configure only the first interface: "ip=eth0:dhcp"
-# QB_CMDLINE_IP_TAP: This parameter is similar to the QB_CMDLINE_IP_SLIRP parameter. Since the tap interface requires
-#                    static IP configuration @CLIENT@ and @GATEWAY@ place holders are replaced by the IP and the gateway
-#                    address of the qemu guest by runqemu.
-#                    Example: "ip=192.168.7.@CLIENT@::192.168.7.@GATEWAY@:255.255.255.0::eth0"
-#
-# QB_ROOTFS_OPT: used as rootfs, e.g.,
-#               "-drive id=disk0,file=@ROOTFS@,if=none,format=raw -device virtio-blk-device,drive=disk0"
-#              Note, runqemu will replace "@ROOTFS@" with the one which is used, such as core-image-minimal-qemuarm64.ext4.
-#
-# QB_SERIAL_OPT: serial port, e.g., "-serial mon:stdio"
-#
-# QB_TCPSERIAL_OPT: tcp serial port option, e.g.,
-#                   " -device virtio-serial-device -chardev socket,id=virtcon,port=@PORT@,host=127.0.0.1 -device virtconsole,chardev=virtcon"
-#                   Note, runqemu will replace "@PORT@" with the port number which is used.
-#
-# QB_ROOTFS_EXTRA_OPT: extra options to be appended to the rootfs device in case there is none specified by QB_ROOTFS_OPT.
-#                      Can be used to automatically determine the image from the other variables
-#                      but define things link 'bootindex' when booting from EFI or 'readonly' when using squashfs
-#                      without the need to specify a dedicated qemu configuration
-#
-# QB_GRAPHICS: QEMU video card type (e.g. "-vga std")
-#
-# Usage:
-# IMAGE_CLASSES += "qemuboot"
-# See "runqemu help" for more info

-#    ROOTFS_DEBUG_FILES += "${TOPDIR}/conf/dropbear_rsa_host_key ${IMAGE_ROOTFS}/etc/dropbear/dropbear_rsa_host_key ;"

-#    ROOTFS_DEBUG_FILES += "${TOPDIR}/conf/dropbear_rsa_host_key ${IMAGE_ROOTFS}/etc/dropbear/dropbear_rsa_host_key 0600;"

-# testimage.bbclass enables testing of qemu images using python unittests.
-# Most of the tests are commands run on target image over ssh.
-# To use it add testimage to global inherit and call your target image with -c testimage
-# You can try it out like this:
-# - first add IMAGE_CLASSES += "testimage" in local.conf
-# - build a qemu core-image-sato
-# - then bitbake core-image-sato -c testimage. That will run a standard suite of tests.
-#
-# The tests can be run automatically each time an image is built if you set
-# TESTIMAGE_AUTO = "1"
-
-TESTIMAGE_AUTO ??= "0"
-
-# You can set (or append to) TEST_SUITES in local.conf to select the tests
-# which you want to run for your target.
-# The test names are the module names in meta/lib/oeqa/runtime/cases.
-# Each name in TEST_SUITES represents a required test for the image. (no skipping allowed)
-# Appending "auto" means that it will try to run all tests that are suitable for the image (each test decides that on it's own).
-# Note that order in TEST_SUITES is relevant: tests are run in an order such that
-# tests mentioned in @skipUnlessPassed run before the tests that depend on them,
-# but without such dependencies, tests run in the order in which they are listed
-# in TEST_SUITES.
-#
-# A layer can add its own tests in lib/oeqa/runtime, provided it extends BBPATH as normal in its layer.conf.
-
-# TEST_LOG_DIR contains a command ssh log and may contain infromation about what command is running, output and return codes and for qemu a boot log till login.
-# Booting is handled by this class, and it's not a test in itself.
-# TEST_QEMUBOOT_TIMEOUT can be used to set the maximum time in seconds the launch code will wait for the login prompt.
-# TEST_OVERALL_TIMEOUT can be used to set the maximum time in seconds the tests will be allowed to run (defaults to no limit).
-# TEST_QEMUPARAMS can be used to pass extra parameters to qemu, e.g. "-m 1024" for setting the amount of ram to 1 GB.
-# TEST_RUNQEMUPARAMS can be used to pass extra parameters to runqemu, e.g. "gl" to enable OpenGL acceleration.
-# QEMU_USE_KVM can be set to "" to disable the use of kvm (by default it is enabled if target_arch == build_arch or both of them are x86 archs)
-
-# TESTIMAGE_BOOT_PATTERNS can be used to override certain patterns used to communicate with the target when booting,
-# if a pattern is not specifically present on this variable a default will be used when booting the target.
-# TESTIMAGE_BOOT_PATTERNS[<flag>] overrides the pattern used for that specific flag, where flag comes from a list of accepted flags
-# e.g. normally the system boots and waits for a login prompt (login:), after that it sends the command: "root\n" to log as the root user
-# if we wanted to log in as the hypothetical "webserver" user for example we could set the following:
-# TESTIMAGE_BOOT_PATTERNS = "send_login_user search_login_succeeded"
-# TESTIMAGE_BOOT_PATTERNS[send_login_user] = "webserver\n"
-# TESTIMAGE_BOOT_PATTERNS[search_login_succeeded] = "webserver@[a-zA-Z0-9\-]+:~#"
-# The accepted flags are the following: search_reached_prompt, send_login_user, search_login_succeeded, search_cmd_finished.
-# They are prefixed with either search/send, to differentiate if the pattern is meant to be sent or searched to/from the target terminal

-# This file is part of U-Boot verified boot support and is intended to be

-#
-# The signature procedure requires the user to generate an RSA key and
-# certificate in a directory and to define the following variable:
-#
-#   UBOOT_SIGN_KEYDIR = "/keys/directory"
-#   UBOOT_SIGN_KEYNAME = "dev" # keys name in keydir (eg. "dev.crt", "dev.key")
-#   UBOOT_MKIMAGE_DTCOPTS = "-I dts -O dtb -p 2000"
-#   UBOOT_SIGN_ENABLE = "1"
-#
-# As verified boot depends on fitImage generation, following is also required:
-#
-#   KERNEL_CLASSES ?= " kernel-fitimage "
-#   KERNEL_IMAGETYPE ?= "fitImage"
-#
-# The signature support is limited to the use of CONFIG_OF_SEPARATE in U-Boot.
-#
-# The tasks sequence is set as below, using DEPLOY_IMAGE_DIR as common place to
-# treat the device tree blob:
-#
-# * u-boot:do_install:append
-#   Install UBOOT_DTB_BINARY to datadir, so that kernel can use it for
-#   signing, and kernel will deploy UBOOT_DTB_BINARY after signs it.
-#
-# * virtual/kernel:do_assemble_fitimage
-#   Sign the image
-#
-# * u-boot:do_deploy[postfuncs]
-#   Deploy files like UBOOT_DTB_IMAGE, UBOOT_DTB_SYMLINK and others.

-# This class is used to help the alternatives system which is useful when
-# multiple sources provide same command. You can use update-alternatives
-# command directly in your recipe, but in most cases this class simplifies
-# that job.
-#
-# To use this class a number of variables should be defined:
-#
-# List all of the alternatives needed by a package:
-# ALTERNATIVE:<pkg> = "name1 name2 name3 ..."
-#
-#   i.e. ALTERNATIVE:busybox = "sh sed test bracket"
-#
-# The pathname of the link
-# ALTERNATIVE_LINK_NAME[name] = "target"
-#
-#   This is the name of the binary once it's been installed onto the runtime.
-#   This name is global to all split packages in this recipe, and should match
-#   other recipes with the same functionality.
-#   i.e. ALTERNATIVE_LINK_NAME[bracket] = "/usr/bin/["
-#
-# NOTE: If ALTERNATIVE_LINK_NAME is not defined, it defaults to ${bindir}/name
-#
-# The default link to create for all targets
-# ALTERNATIVE_TARGET = "target"
-#
-#   This is useful in a multicall binary case
-#   i.e. ALTERNATIVE_TARGET = "/bin/busybox"
-#
-# A non-default link to create for a target
-# ALTERNATIVE_TARGET[name] = "target"
-#
-#   This is the name of the binary as it's been install by do_install
-#   i.e. ALTERNATIVE_TARGET[sh] = "/bin/bash"
-#
-# A package specific link for a target
-# ALTERNATIVE_TARGET_<pkg>[name] = "target"
-#
-#   This is useful when a recipe provides multiple alternatives for the
-#   same item.
-#
-# NOTE: If ALTERNATIVE_TARGET is not defined, it will inherit the value
-# from ALTERNATIVE_LINK_NAME.
-#
-# NOTE: If the ALTERNATIVE_LINK_NAME and ALTERNATIVE_TARGET are the same,
-# ALTERNATIVE_TARGET will have '.{BPN}' appended to it.  If the file
-# referenced has not been renamed, it will also be renamed.  (This avoids
-# the need to rename alternative files in the do_install step, but still
-# supports it if necessary for some reason.)
-#
-# The default priority for any alternatives
-# ALTERNATIVE_PRIORITY = "priority"
-#
-#   i.e. default is ALTERNATIVE_PRIORITY = "10"
-#
-# The non-default priority for a specific target
-# ALTERNATIVE_PRIORITY[name] = "priority"
