# 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
CONFIG_ARCH_SIM=y
CONFIG_ARCH_BOARD=sim
CONFIG_ARCH_BOARD_SIM=y

#
# General OS setup
#
# CONFIG_APPS_DIR - Identifies the relative path to the directory
#   that builds the application to link with NuttX.  Default: ../apps
# CONFIG_DEBUG - enables built-in debug options
# CONFIG_DEBUG_VERBOSE - enables verbose debug output
# CONFIG_DEBUG_SYMBOLS - build without optimization and with
#   debug symbols (needed for use with a debugger).
# 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_MSEC_PER_TICK - The default system timer is 100Hz
#   or MSEC_PER_TICK=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.
# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
#   driver (minimul support)
# CONFIG_MUTEX_TYPES: Set to enable support for recursive and
#   errorcheck mutexes. Enables pthread_mutexattr_settype().
# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
#   inheritance on mutexes and semaphores. 
# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
#   inheritance is enabled.  It defines the maximum number of
#   different threads (minus one) that can take counts on a
#   semaphore with priority inheritance support.  This may be 
#   set to zero if priority inheritance is disabled OR if you
#   are only using semaphores as mutexes (only one holder) OR
#   if no more than two threads participate using a counting
#   semaphore.
# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
#   then this setting is the maximum number of higher priority
#   threads (minus 1) than can be waiting for another thread
#   to release a count on a semaphore.  This value may be set
#   to zero if no more than one thread is expected to wait for
#   a semaphore.
# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
#   by task_create() when a new task is started.  If set, all
#   files/drivers will appear to be closed in the new task.
# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
#   three file descriptors (stdin, stdout, stderr) by task_create()
#   when a new task is started. If set, all files/drivers will
#   appear to be closed in the new task except for stdin, stdout,
#   and stderr.
# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
#   desciptors by task_create() when a new task is started. If
#   set, all sockets will appear to be closed in the new task.
