# architecture selection
#
# CONFIG_ARCH - identifies the arch subdirectory
# CONFIG_ARCH_name - for use in C code
#
CONFIG_ARCH=sim
CONFIG_ARCH_SIM=y

#
# General OS setup
#
# CONFIG_EXAMPLE - identifies the subdirectory in examples
#   that will be used in the build
# CONFIG_DEBUG - enables built-in debug options
# CONFIG_DEBUG_VERBOSE - enables verbose debug output
# CONFIG_MM_REGIONS - If the architecture includes multiple
#   regions of memory to allocate from, this specifies the
#   number of memory regions that the memory manager must
#   handle and enables the API mm_addregion(start, end);
# CONFIG_HAVE_LOWPUTC - architecture supports low-level, boot
#   time console output
# CONFIG_RR_INTERVAL - The round robin timeslice will be set
#   this number of milliseconds;  Round robin scheduling can
#   be disabled by setting this value to zero.
# CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in 
#   scheduler to monitor system performance
# CONFIG_TASK_NAME_SIZE - Spcifies that maximum size of a
#   task name to save in the TCB.  Useful if scheduler
#   instrumentation is selected.  Set to zero to disable.
# CONFIG_JULIAN_TIME - Enables Julian time conversions
# CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY -
#   Used to initialize the internal time logic.
# CONFIG_DEV_CONSOLE - Set if architecture-specific logic
#   provides /dev/console.  Enables stdout, stderr, stdin.

# The following can be used to disable categories of
# APIs supported by the OS.  If the compiler supports
# weak functions, then it should not be necessary to
# disable functions unless you want to restrict usage
# of those APIs.
#
# There are certain dependency relationships in these
# features.
#
# o mq_notify logic depends on signals to awaken tasks
#   waiting for queues to become full or empty.
# o pthread_condtimedwait() depends on signals to wake
#   up waiting tasks.
