###############################################################################
#
# This script is for starting QEMU against the input build and running the
# robot CI test suite against it.(ROBOT CI TEST CURRENTLY WIP)
#
###############################################################################
#
# Parameters used by the script:
#  UPSTREAM_WORKSPACE = The directory from which the QEMU components are being
#                       imported from. Generally, this is the build directory
#                       that is generated by the OpenBMC build-setup.sh script
#                       when run with "target=qemu".
#                       Example: /home/builder/workspace/openbmc-build/build.
#
# Optional Variables:
#
#  WORKSPACE          = Path of the workspace directory where some intermediate
#                       files will be saved to.
#  QEMU_RUN_TIMER     = Defaults to 300, a timer for the QEMU container.
#  DOCKER_IMG_NAME    = Defaults to openbmc/ubuntu-robot-qemu, the name the
#                       Docker image will be tagged with when built.
#  OBMC_BUILD_DIR     = Defaults to /tmp/openbmc/build, the path to the
#                       directory where the UPSTREAM_WORKSPACE build files will
#                       be mounted to. Since the build containers have been
#                       changed to use /tmp as the parent directory for their
#                       builds, move the mounting location to be the same to
#                       resolve issues with file links or referrals to exact
#                       paths in the original build directory. If the build
#                       directory was changed in the build-setup.sh run, this
#                       variable should also be changed. Otherwise, the default
#                       should be used.
