+
+NuttX-7.6
+---------
+
+The 106th release of NuttX, Version 7.6, was made on November 26, 2014,
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-7.5.tar.gz and
+apps-7.5.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+Additional new features and extended functionality:
+
+ * Core OS:
+
+ - Moved name semaphore and message queue support out of the OS and
+ into the VFS. These improves the architecture by unifying the
+ management of named resources, removes redundant resource management
+ logic, and makes named semaphores and message queues visible in the
+ file system. By default, these are visible at /var/lock and
+ /var/mqueue.
+ - Add SIGPOLL for use as part of the AIO implementation.
+ - Remove CONFIG_MAX_TASK_ARGS configuration. There is now no
+ predetermined limit on the number of arguments that may be passed
+ to a new task on start-up.
+
+ * Work queues
+
+ - Add support for priority inheritance on the low priority worker
+ queue. That is, if a higher priority thread has scheduled work, the
+ priority of the low priority worker thread(s) will be boost to the
+ priority of the queuing thread. At work is performed at at least
+ thread priority of the scheduling thread. If there are multiple
+ worker threads, then all threads get reprioritized. Currently
+ only implemented for AIO.
+ - Add support for multiple low-priority work queue threads. This
+ allows individual worker threads to block indefinitely for I/O as
+ necessary without halting the entire work queue.
+
+ * VFS/General Drivers:
+
+ - Implement create() (as a macro).
+ - Add pread() and pwrite(). Also added pread() and pwrite()
+ system calls.
+ - AIO: Add aio_read(), aio_write(), aio_return(), aio_error(),
+ aio_suspend(), aio_canel(), lio_listio(), and aio_fsync(). This
+ logic minimizes the creation of new threads by using the new
+ features also added to the low priority work queue with this
+ release. It uses the new low priority worker thread interface
+ to adjust the priority of the worker thread according to the
+ priority of the AIO client thread
+ - Implement standard syslogmask() to control logging (also removing
+ the non-standard syslog_enable()).
+
+ * File Systems/Block Drivers/MTD:
+
+ - Extend MTD support to the M25P16. From S�bastien Lorquet.
+
+ * Drivers:
+
+ - BCH (Block-to-Charchter): Add support for seeking in BCH. From
+ S�bastien Lorquet.
+
+ * Graphics Support/Graphics-Related Drivers:
+
+ - Add support for a generic ILI9341 LCD driver. From Marco Krahl.
+ - Add ANSI/VT100 foreground and background color commands.
+ - Add driver for ST7565 LCD that works with NHD-C12864KGZ display. From Pierre-noel Bouteville.
+
+ * Networking:
+
+ - Verify that multiple networks can be supported.
+ - Add support for the case where there are multiple networks: One
+ being Ethernet and the other not (SLIP, PPP, ...). The primary
+ difference from the standpoint of the stack is that (1) ARP may or
+ may not be necessary, (2) the size of the link layer header will
+ vary, and (3) different MTUs and TCP receive windows may be used
+ with each link. Suggested by Brennan Ashton.
+ - Extensions to UDP and TCP connection structures for the case of
+ multiple networks. In this case, assigned port numbers only have to
+ be unique with respect to the IP address. So, for example, you
+ could have multiple port 80's, one on each network.
+
+ * Host Simulation:
+
+ - Removed the old, strange up_stdio.c and implemented a simulated UART
+ driver to provide the console input. The new logic starts a
+ separate, Linux domain pthread to read the console input in raw mode
+ and provides the incoming data to NuttX via standard NuttX domain
+ IPCs.
+ - Add support for 64-bit longjmp/setjmp in simulator platform. This
+ will permit operation of the simulation natively on a 64-bit
+ platform.
+
+ * ARMv7-M:
+
+ - Add ARMv7-M CMSIS ITM header file and library. From Pierre-noel
+ Bouteville.
+ - Add ARMv7-M CMSIS DWT and TPI header files. From Pierre-noel
+ Bouteville.
+ - Add ARMv7.M support to use ITM for SYSLOG debug output. Includes
+ logic from Pierre-noel Bouteville.
+
+ * Atmel SAM3/4 Drivers:
+
+ - Add support for SAM3/4 basic serial TERMIOS and flow control.
+ There are issues with IFLOW control: PDC or DMAC support is
+ required.
+
+ * Atmel SAM3/4 Boards:
+
+ - SAM4E-EK: Add support for PHY interrupt.
+
+ * Atmel SAMA5D Boards:
+
+ - SAMA5D3-Xplained: Add a configuration that provides a simple test
+ for the EMAC and GMAC on the SAMA5D3 working together.
+ - SAMA5D4-EK: Add a configuration that provides a simple test for th
+ EMAC0 and EMAC1 on the SAMA5D4 working together.
+
+ * Freescale KL:
+
+ - Add an I2C header file for the Freescale KL family. From Alan
+ Carvalho de Assis.
+
+ * NXP LPC32xx.
+
+ - Add support for tickless operation using the NXP LPC43xx. From
+ Brandon Warhurst.
+
+ * SiLabs EFM32:
+
+ - Add a basic port for the SiLabs EFM32 family. Includes many files
+ contributed by Pierre-noel Bouteville .
+
+ * SiLabs EFM32 Boards:
+
+ - Add board support for the EFM32 Gecko Starter Kit.
+ - Add board support for the Olimex EFM32G8809128 STK. NOTE: I am
+ unable to test this configuration due to tool-related issues.
+ - Add board support for the SiLbas EFM32GG Giant Gecko Starter kit.
+
+ * STMicro STM32:
+
+ - Add support for the STM32 F411RE from Serg Podtynnyi.
+ - Add support for the STM32F103RG. From Murilo Ponte.
+
+ * STMicro STM32 Drivers:
+
+ - STM32 F4: Add logic that implement true high speed support for the
+ STM32 OTGHS peripheral and concurrent support for both LS and HS
+ OTG. New OTGHS drivers provided for both device and host. From
+ Brennan Ashton.
+
+ * STMicro STM32 Boards:
+
+ - STM32 Nucleo-F411RE: Extend this board configuration to also support
+ the Nucleo-F411RE. From Serg Podtynnyi.
+ - Add support for the STM32F429i Discovery's LCD (SPI based). From
+ Marco Krahl.
+ - configs/stm32f100rc_generic: Removed this generic board configuration.
+ I have decided to stop support of generic board configurations. Generic
+ board configurations do not provide support for any specific hardware
+ but can be useful only if there are not other examples for the setup
+ for a particular architecture. Not the case here.
+
+ * C Library:
+
+ - Add a mostly bogus wchar.h header file. This file is mostly bogus
+ because none of the wide character operations are currently
+ supported in the Nuttx C library. The file does provide the wchar_t
+ types needed by some software, however.
+ - Add isatty() function. From Alan Carvalho de Assis.
+ - Add mktemp(), mkstemp(), tmpnam() and tempnam().
+
+ * Configuration/Build System:
+
+ - Add a PRELINK macro to Config.mk. From Kriegleder.
+ - compiler.h: Defines inline functions as not instrumented - this is
+ relevant for anyone using instrumentation. From Lorenz Meier.
+
+ * Applications:
+
+ - apps/interpreter/bas: Added in the Michael Haardt's BAS 2.4 adapted
+ for use by NuttX by Alan Carvalho de Assis. Includes support for
+ VT100 terminals and color commands.
+ - Examples: Added bastest/ which holds a special version of Michael
+ Haardt's BAS 2.4 test files adapted for use by NuttX on a ROMFS file
+ system.
+ - Examples: Add a simple UDP relay bridge for testing configurations
+ with multiple networks. Includes a host-side test driver for
+ testing the bridge.
+ - Netutils: Add implementation of timeouts for the netutils webclient.
+ From Brennan Ashton
+ - NSH: Add support for a custom NSH ROMFS startup image header file
+ location. From Martin Lederhilger.
+ - OS test: Add a simple test of named semaphores.
+ - OS test: Add AIO test case in OS test.
+
+Efforts In Progress. The following are features that are partially
+implemented but present in this release. They are not likely to be
+completed soon.
+
+ * Processes. Much of the work in this release is focused on the
+ realization of Unix-style user processes in NuttX. There is more to
+ be done, however. The full roadmap and status is available at:
+ http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes
+
+ * XMega: There are some fragments in place for an XMega port. That
+ port has not really started, however.
+
+ * Galileo: Similarly, there are fragments in place for an Intel Galileo
+ port. The port not been started in earnest either.
+
+Bugfixes. Only the most critical bugfixes are listed here (see the
+ChangeLog for the complete list of bugfixes and for additional, more
+detailed bugfix information):
+
+I ran cppcheck against the entire code base and correct many latent bugs
+including things as serious as memory leaks, two locations where interrupts
+were be disabled but never re-enabled, and errors in the Tickless mode of
+operation. My thanks to the developers of cppcheck! I am impressed!
+
+ * Core OS:
+
+ - vfork(): Now that arguments are kept on the stack, the way that
+ arguments are passed from parent to child in vfork() must change.
+ This bug has always been present, but was not visible with the
+ old strdup() way of passing arguments.
+ - vfork() problem: If we get to vfork() via system call, then we
+ eed to clone some system call information so that the return form
+ the cloned system call works correctly.
+ - Fixes to tickless operation code, especially in alarm mode. From
+ Brandon Warhurst.
+ - Fix an important bug in the watchdog timer creation logic.
+ - Calling mq_timedreceived() with immediate timeout was getting stuck
+ and not timing out. Immediate timeout is achieved by setting absolute
+ timeout value to past time, for example abstime={ .tv_sec=0,
+ .tv_nsec=0 }. However absolute time was converted to relative time
+ using unsigned integer arithmetic and resulted large ticks count by
+ clock_abstime2ticks, instead of expected negative ticks value.
+ Change corrects clock_abstime2ticks() to return negative ticks, if
+ absolute time is in the past. From Jussi Kivilinna.
+
+ * Memory Management:
+
+ - Fix a place in the memory manager where it explicitly assumed that
+ the size of a pointer is 4 bytes. That assumption was OK if the
+ actual size is smaller but made the heap unstable when used with
+ the x86_64 host simulation.
+ - Granule Allocator: If the INTR granule allocator mode is enabled,
+ there is no semaphore to destroy. From Lorenz Meier.
+
+ * Networking:
+
+ - Network routing: I don't think that the net_route() function has
+ ever worked correctly. The source IP was updated in the match
+ struct instead of the route IP. From Brennan Ashton.
+ - Move and rename IP header flag definitions. The problem fixed here
+ is that there IP header flag definitions were not available when TCP
+ was disabled. The IP flags are used in ICMP and IGMP.
+ - Network routing: Refuse to perform routing table lookups for the
+ Broadcast IP address. From Brennan Ashton.
+ - Network routing: Add logic to netdev_findbyaddr() to return the
+ correct network device for the case where a broadcast
+ address is used. This change caused trivial ripples through other
+ files because additional parameters are required for
+ netdev_findbyaddr() when CONFIG_NET_MULTINIC.
+
+ * File Systems/Block Drivers/MTD:
+
+ - NXFFS Dump: Fix problems with redefinitions of fdbg macro. With the
+ fix to the syslog prototype, a LOG priority must now be the first
+ parameter. Fixed by replacing all occurrences of fdbg with
+ syslog(LOG_DEBUG, and eliminating the macro redefinitions. Noted
+ by Sebastien Lorquet.
+ - poll() was not waking up from signals (for example mq_notify()
+ events). From Jussi Kivilinna.
+ - poll(): Add proper handling for sem_timedwait errnos. From Jussi
+ Kivilinna.
+ - include/nuttx/fs/fs.h: Fix typo in conditional compilation. From
+ Alan Carvalho de Assis.
+
+ * Graphics/Graphic-Related Drivers:
+
+ - Remove warnings when CONFIG_NXTK_BORDERWIDTH is set to zero. From
+ Pierre-Noel Bouteville.
+
+ * Common Drivers:
+
+ - Make standard syslog and vsyslog POSIX compliant (also modify
+ non-standard syslog functions for compatibility).
+ - R/W buffering: Fix typo that can cause compilation error.
+
+ * Atmel SAM3/4:
+
+ - SAM4S: Add missing SPI0 clock configuration macro for the SAM4S. From spasbyspas.
+
+ * Atmel SAM3/4 Drivers:
+
+ - SAM4E-EK: Fix an error in a USART1 pin number.
+
+ * Atmel SAMA5D3/4 Drivers:
+
+ - SAMA5DF4: Fix several typos that will prevented EMAC1 from
+ initializing properly.
+
+ * NXP LPC43xx:
+
+ - Fixes to allow compile of lpc43_gpioint.c. From Brandon Warhurst.
+
+ * STMicro STM32:
+
+ - Add missing ADC pinmap definitions for the STM32 F103R from Martin
+ Lederhilger.
+
+ * STMicro STM32 Drivers:
+
+ - STM32 EXTI: Correct STM32 RTC EXTI bit definition. From Lazlo.
+ - STM32 IWDG, WWDG, DBGMCU: Fix watchdog stop bit usage. From Lazlo.
+ - STM32 OTGFS: Correct a typo in the STM32 OTGFS register bit definitions.
+
+ * ARM:
+
+ - ARM up_internal.h: Add protection from C++ name mangling in the
+ ARM up_internal.h. From Lorenz Meier.
+
+ * MicroChip PIC32MX
+
+ - PIC32MX7: DEVCFG0 bit 2 must be set. Writing bit 2 as zero can
+ brick the CPU on some versions. From Cris Kvist.
+
+ * C Library:
+
+ - The implementation of access() as vararg macro has the issue that
+ any function call with the same name (even in a C++ class) will
+ match with it and result in a compile error. Replaced with a small
+ function. This resolves the compile issue, and shouldn�t have
+ negative side effects for users of the function. From Lorenz Meier.
+ - The definition of strncpy() is that empty space should be zero-
+ filled, the change adds the zero filling (See the POSIX spec here:
+ http://pubs.opengroup.org/onlinepubs/7908799/xsh/strncpy.html). From
+ Lorenz Meier.
+ - limits.h: Remove the definition of INT_FAST32_MIN which is already
+ defined in stdint.h (the correct location). From Lorenz Meier.
+
+ * Applications:
+
+ - apps/: Correct everything under apps to use the corrected syslog
+ interfaces. Remove any non-portable uses of syslog.
+ - NSH: Fix ls -l output for regular files.
+ - NSH: Fix reversed in/out file closing in DD command when an error
+ occurs. From Ken Pettit.
+ - NSH: Add logic to restart the console wait if an error occurs
+ while reading from the console. In USB console startup, the logi
+ must be able to open the USB serial and receive 3 newlines.
+ However, it the USB driver is disconnected or otherwise fails before
+ the 3 newlines are received, the receive loop becomes a killer,
+ infinite loop, CPU hog. Noted by spasbyspas.
+ - Netutils: Fix memcpy of host address in netlib_gethostaddr(). From
+ Brennan Ashton.
+ - Netutils: If you make a DNS request before the DNS address it would
+ cause an assertion. The state of the IP setting is not something the
+ application should be aware of, it should only be concerned with
+ whether or not the name was resolved. From Brennan Ashton.
+ - Netutils: Fix md5 hashing when digest[$i] islower that 16. From
+ Sergey.
+ - Stack Monitor: Fix compile problems introduced when the syslog()
+ prototype changed; Also update Makefile for kernel build From
+ Radoslaw Adamczyk.
+ - Examples: Update NxTerm makefile for kernel-build issues. From
+ Radoslaw Adamczyk.
+ - Examples: Fixes to keypadtest from Pierre-Noel Bouteville.
+ - Examples: These examples all set the IP address of eth1 but the
+ netmask and gateway of eth0 if DHCP is enabled: discover, tcpecho,
+ webserver, xmlrpc. That can't be right.
