-# This file is your local configuration file and is where all local user settings

-# to the system might want to change but pretty much any configuration option can
-# be set in this file.
-#
-# Lines starting with the '#' character are commented out and in some cases the

-#
-# Machine Selection
-#
-MACHINE ??= "template"
-#
-# Where to place downloads
-#
-# During a first build the system will download many different source code tarballs
-# from various upstream projects. This can take a while, particularly if your network
-# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
-# can preserve this directory to speed up this part of subsequent builds. This directory
-# is safe to share between multiple builds on the same machine too.
-#
-# The default is a downloads directory under TOPDIR which is the build directory.
-#
-DL_DIR ?= "${TOPDIR}/../downloads"
-#
-# Where to place shared-state files
-#
-# BitBake has the capability to accelerate builds based on previously built output.
-# This is done using "shared state" files which can be thought of as cache objects
-# and this option determines where those files are placed.
-#
-# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
-# from these files if no changes were made to the configuration. If changes were made
-# to the configuration, only shared state files where the state was still valid would
-# be used (done using checksums).
-#
-# The default is a sstate-cache directory under TOPDIR.
-#
-#SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
-#
-# Where to place the build output
-#
-# This option specifies where the bulk of the building work should be done and
-# where BitBake should place its temporary files and output. Keep in mind that
-# this includes the extraction and compilation of many applications and the toolchain
-# which can use Gigabytes of hard disk space.
-#
-# The default is a tmp directory under TOPDIR.
-#
-#TMPDIR = "${TOPDIR}/tmp"
-#
-# Default policy config
-#
-# The distribution setting controls which policy settings are used as defaults.
-# The default value is fine for general Yocto project use, at least initially.
-# Ultimately when creating custom policy, people will likely end up subclassing
-# these defaults.
-#
-DISTRO ?= "openbmc-phosphor"
-# As an example of a subclass there is a "bleeding" edge policy configuration
-# where many versions are set to the absolute latest code from the upstream
-# source control systems. This is just mentioned here as an example, its not
-# useful to most new users.
-# DISTRO ?= "poky-bleeding"
-#
-# Package Management configuration
-#
-# This variable lists which packaging formats to enable. Multiple package backends
-# can be enabled at once and the first item listed in the variable will be used
-# to generate the root filesystems.
-# Options are:
-#  - 'package_deb' for debian style deb files
-#  - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
-#  - 'package_rpm' for rpm style packages
-# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
-# We default to ipk:
-PACKAGE_CLASSES ?= "package_ipk"
-#
-# SDK/ADT target architecture
-#
-# This variable specifies the architecture to build SDK/ADT items for and means
-# you can build the SDK packages for architectures other than the machine you are
-# running the build on (i.e. building i686 packages on an x86_64 host).
-# Supported values are i686 and x86_64
-#SDKMACHINE ?= "i686"
-SANITY_TESTED_DISTROS_append ?= " *"
-#
-# Extra image configuration defaults
-#
-# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
-# images. Some of these options are added to certain image types automatically. The
-# variable can contain the following options:
-#  "dbg-pkgs"       - add -dbg packages for all installed packages
-#                     (adds symbol information for debugging/profiling)
-#  "dev-pkgs"       - add -dev packages for all installed packages
-#                     (useful if you want to develop against libs in the image)
-#  "ptest-pkgs"     - add -ptest packages for all ptest-enabled packages
-#                     (useful if you want to run the package test suites)
-#  "tools-sdk"      - add development tools (gcc, make, pkgconfig etc.)
-#  "tools-debug"    - add debugging tools (gdb, strace)
-#  "eclipse-debug"  - add Eclipse remote debugging support
-#  "tools-profile"  - add profiling tools (oprofile, exmap, lttng, valgrind)
-#  "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
-#  "debug-tweaks"   - make an image suitable for development
-#                     e.g. ssh root access has a blank password
-# There are other application targets that can be used here too, see
-# meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.
-# We default to enabling the debugging tweaks.
-EXTRA_IMAGE_FEATURES = "debug-tweaks"
-#
-# Additional image features
-#
-# The following is a list of additional classes to use when building images which
-# enable extra features. Some available options which can be included in this variable
-# are:
-#   - 'buildstats' collect build statistics
-#   - 'image-prelink' in order to prelink the filesystem image
-#   - 'image-swab' to perform host system intrusion detection
-# NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
-# NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended
-USER_CLASSES ?= "buildstats image-prelink"
-#
-# Runtime testing of images
-#
-# The build system can test booting virtual machine images under qemu (an emulator)
-# after any root filesystems are created and run tests against those images. To
-# enable this uncomment this line. See classes/testimage(-auto).bbclass for
-# further details.
-#TEST_IMAGE = "1"
-#
-# Interactive shell configuration
-#
-# Under certain circumstances the system may need input from you and to do this it
-# can launch an interactive shell. It needs to do this since the build is
-# multithreaded and needs to be able to handle the case where more than one parallel
-# process may require the user's attention. The default is iterate over the available
-# terminal types to find one that works.
-#
-# Examples of the occasions this may happen are when resolving patches which cannot
-# be applied, to use the devshell or the kernel menuconfig
-#
-# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
-# Note: currently, Konsole support only works for KDE 3.x due to the way
-# newer Konsole versions behave
-#OE_TERMINAL = "auto"
-# By default disable interactive patch resolution (tasks will just fail instead):
-PATCHRESOLVE = "noop"
-#
-# Disk Space Monitoring during the build
-#
-# Monitor the disk space during the build. If there is less that 1GB of space or less
-# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
-# shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
-# of the build. The reason for this is that running completely out of space can corrupt
-# files and damages the build in ways which may not be easily recoverable.
-# It's necessary to monitor /tmp, if there is no space left the build will fail
-# with very exotic errors.

-# Shared-state files from other locations
-#
-# As mentioned above, shared state files are prebuilt cache data objects which can
-# used to accelerate build time. This variable can be used to configure the system
-# to search other mirror locations for these objects before it builds the data itself.
-#
-# This can be a filesystem directory, or a remote url such as http or ftp. These
-# would contain the sstate-cache results from previous builds (possibly from other
-# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
-# cache locations to check for the shared objects.
-# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
-# at the end as shown in the examples below. This will be substituted with the
-# correct path within the directory structure.
-#SSTATE_MIRRORS ?= "\
-#file://.* http://someserver.tld/share/sstate/PATH;downloadfilename=PATH \n \

-# Qemu configuration
-#
-# By default qemu will build with a builtin VNC server where graphical output can be
-# seen. The two lines below enable the SDL backend too. This assumes there is a
-# libsdl library available on your build system.
-#PACKAGECONFIG_append_pn-qemu-native = " sdl"

-#ASSUME_PROVIDED += "libsdl-native"

-# track the version of this file when it was generated. This can safely be ignored if
-# this doesn't mean anything to you.
