+  RGMP stands for RTOS and GPOS on Multi-Processor.  RGMP is a project for 
+  running GPOS and RTOS simultaneously on multi-processor platforms. You can
+  port your favorite RTOS to RGMP together with an unmodified Linux to form a
+  hybrid operating system. This makes your application able to use both RTOS
+  and GPOS feathures.

 configs/sim
 	A user-mode port of NuttX to the x86 Linux platform is available.
 	The purpose of this port is primarily to support OS feature development.

+# CONFIG_ARCH - identifies the arch subdirectory and, hence, the

+# 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)

+
+#
+# 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.

+# 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=rgmp
+CONFIG_ARCH_RGMP=y
+CONFIG_ARCH_BOARD=rgmp
+CONFIG_ARCH_BOARD_RGMP=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.
