# Architecture selection
#
# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
#   processor architecture.
# CONFIG_ARCH_name - for use in C code.  This identifies the particular
#   processor architecture (CONFIG_ARCH_SIM).
# CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
#   the board that supports the particular chip or SoC.
# CONFIG_ARCH_BOARD_name - for use in C code
# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
#
CONFIG_ARCH=sim

#
# 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_ARCH_LOWPUTC - architecture supports low-level, boot
#   time console output
# CONFIG_TICKS_PER_MSEC - The default system timer is 100Hz
#   or TICKS_PER_MSEC=10.  This setting may be defined to
#   inform NuttX that the processor hardware is providing
#   system timer interrupts at some interrupt interval other
#   than 10 msec.
# 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

# 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
