+NuttX-9.1.0 Release Notes -------------------------
+
+ * Major Changes to Core OS:
+ * New Features:
+ - PR-977 PR-987 PR-998 PR-995 PR-997 PR-1007 Thread Local Storage (TLS)
+ is now a required feature and used by all architectures
+ There is detailed information on the implementation and how this
+ impacts errno specifically in the Wiki article: Userspace errno and
+ TLS
+ - PR-957 PR-947 PR-963 PR-969 Provide nx_ versions of many functions
+ that are used internally to avoid disrupting errno in userspace
+ - PR-965 PR-980 PR-984 ioctl is now always in the variadic form.
+ Syscalls in KERNEL builds are also more efficient with this as well now.
+ Previously the ioctl prototype was normally defined as:
+
+ int ioctl(int fd, int cmd, unsigned long arg);
+
+ unless the CONFIG_LIBC_IOCTL_VARIADIC was enabled in which case it was
+
+ int ioctl(int fd, int cmd, ...); This form is now the form defined by
+ opengroup and is also inline with Linux. Prior to this change there
+ were issues with making ioctl calls on 64-bit arch since the
+ implementation assumed that (void *) would be of size long. There is
+ more discussion of this issue in the GitHub issue ticket here:
+
+ https://github.com/apache/incubator-nuttx/issues/959
+
+ - PR-962 PR-964 Add new interface sched_get_stackinfo that simplifies
+ interfaces for things like TLS
+ There are some security imposed rules for using this interface
+ Any thread may query its own stack, A kernel thread may query the
+ stack of any other thread Application threads, however, may query
+ only the stacks of threads within the same task group, i.e., the
+ main thread and any of the child pthreads created with the main
+ thread as a parent or grandparent or great-grandparent.
+
+ - PR-1104 Internal function fs_fsopen() no longer affects errno -
+ - PR-1123 Move task_init() and task_activate() to be internal functions -
+ - PR-1140 Add nxtask_uninit() interface
+ This function will undo all operations on a TCB performed by
+ task_init() and release the TCB by calling kmm_free(). This is
+ intended primarily to support error recovery operations after a
+ successful call to task_init() such was when a subsequent call to
+ task_activate fails.
+ - PR-1134 Add typedef for max_align_t
+ - PR-1141 Handle custom stack allocations
+ sched_releasetcb() will normally free the stack allocated for a task.
+ However, a task with a custom, user-managed stack may be created using
+ nxtask_init() followed by nxtask_activate(). If such a custom stack is
+ used then it must not be freed in this manner or a crash will most
+ likely result.
+
+ This change adds a flag call TCB_FLAG_CUSTOM_STACK that may be passed
+ in the the pre-allocated TCB to nxtask_init(). This flag is not used
+ internally anywhere in the OS except that if set, it will prevent
+ sched_releasetcb() from attempting to free that custom stack.
+
+ * Bug Fixes:
+ - Many private architecture interfaces were using 'up_' instead of the
+ arch name 'arm_'
+ This fix is carried over many PRs such as PR-924. Many files also
+ carried this same error in naming convention and were converted as
+ well.
+
+ - PR-1018 PR-1017 PR-1021 PR-1022 PR-1057 PR-1060 PR-1194 Clean up
+ internal APIs that were not using the properly naming conventions -
+ - PR-857 Wrong value for it_interval field in timespec returned by
+ timer_gettime - PR-902 SMP: On task creation do not clone
+ uninitialized descriptors
+ In SMP mode, there is a possibility that a pthread executing one CPU
+ may create a new task while a pthread on another CPU has allocated
+ the socket but not yet initialized it. This commit updates the
+ socket clone test to assure that the socket is both allocated and
+ initialized before it is cloned.
+ - PR-911 Use OS signal functions internally to not reset errno that
+ applications are using
+ - PR-925 sys/stat.h Change the xtime fields to align with POSIX
+ standard. Starting from Issue 7 of the POSIX standard the fields
+ st_atime, st_mtime and st_ctime have a type of strcut timespec instead
+ of time_t.
+ - PR-939 openamp: Update to 2020.04.0 - PR-953 lib_vsprintf: Fix issue
+ where stack would become corrupt on x86_64
+ This function requires traversing the VA_LIST twice. For some
+ architectures like x86 and x86_64 this needs to be cloned first.
+
+ * Major Changes to the Build System:
+ Parts of the build system have been refactored to reduce duplication and
+ simplify Makefile and Make.defs files across many directories. These changes
+ are particularly beneficial for boards.
+
+ Please note that if you develop your own custom boards, you may need to make
+ some modifications to keep your board's build scripts up-to-date with the
+ rest of NuttX and avoid a broken or defective build. For details, see
+ Compatibility Concerns, Changes to Build System, in these release notes.
+
+ * New Features:
+ - PR-894 openamp and libmetal can now be downloaded and configured by
+ build system - PR-941 Remove 'u' prefix from userspace library in FLAT
+ Build so it is the same for all build types - PR-1044 ARM: Remove
+ support for old redundant gcc toolchains
+
+ This removes support for the Codesourcery, Atollic, DevKitArm,
+ Raisonance, and CodeRed toolchains. Not only are these tools old and
+ no longer used but they are all equivalent to the standard ARM EABI
+ toolchains. Retaining specific support was not meaningful (and they
+ are still supported, but now just as generic EABI toolchains).
+ - PR-1148 PR-1149 Improve build time especially on non-Linux platforms
+ by providing a C version of incdir.sh
+
+ * Bug Fixes:
+ Many small changes to resolve dependency resolution issues that would
+ sometimes appear during parallel builds. Parallel builds should be much
+ more reliable now and bugs filed against any issues found.
+
+ - PR-1000 Fix broken support of ZDS-II Toolchain with MSYS
+
+ * Architectural Support:
+ * New Architecture Support:
+ - PR-879 ARMv8-M support - PR-1051 STM32G474 support
+
+ - Initial architectural support for the STM32G474 family of
+ microcontrollers. In terms of peripherals, currently there is basic
+ support for the RCC and UART, allowing NuttX to boot to a functional
+ NSH prompt on this family. Other peripherals on the SoC are not yet
+ supported and/or not tested yet. Contributions to enable other
+ peripherals are welcome. This adds support for these variants:
+
+ STM32G474C STM32G474M STM32G474R STM32G474Q STM32G474V
+
+ * Architectures With Significant Improvements:
+ - PR-745 The full line of STM32H7 chips are now defined
+ This adds support for these variants:
+
+ STM32H743AG STM32H743AI STM32H743BG STM32H743BI STM32H743IG
+ STM32H743II STM32H743VG STM32H743VI STM32H743XG STM32H743XI
+ STM32H743ZG STM32H753AI STM32H753BI STM32H753VI STM32H753XI
+ STM32H753ZI
+
+ - PR-811 i486: Fix corruption of esp register on full context restore
+ This resolves a long standing issue with running the x86 port under
+ QEMU where it would crash shortly after boot.
+
+ - PR-837 rx65n: Add crashdump support using standby RAM - PR-862
+ STM32L4: Expose LPTIM timers - PR-868 STM32L4: Extend clock options and
+ power regulation for based on clock settings
+ Interface to select the core regulator voltage according to clock
+ frequency range Usage of this interface during clock configuration
+ according to chosen clock frequency Option to choose a different
+ system clock than the main PLL (there is HSI, MSI, HSE and LSE
+ available to use) Option to not enable the main PLL which allows for
+ reduced power usage when setting one of the above options as system
+ clock, to do this you should define STM32L4_BOARD_NOPLL on your
+ board header.
+ - PR-960 STM32: Add support for ADC features EXTSEL and JEXTSEL
+ - PR-1041 STM32H7: Improve IDMA transfer and cache handling
+ This resolves an issue where the sdmmc driver crashes at boot when
+ using writeback cache.
+
+ This also simplifies the sdmmc driver when the IDMA is in use. There
+ is no need to mix IDMA and interrupt based transfers; instead, when
+ making unaligned data tranfers, just make IDMA into an internal
+ aligned buffer and then copy the data. This method also enables
+ multiblock transfers, and transfers from/to data buffers which are not
+ aligned on cache boundary.
+ - PR-1042 STM32H7: Resolve multiple limitations and bugs with progmem
+ especailly for partial memory writes
+ - PR-1045 STM32H7: This gives possibility to send arbitrary number of
+ bytes from memory to peripheral using DMA also when using write-back
+ cache
+ It was not possible to DMA to/from AXI sram if
+ CONFIG_STM32H7_DMACAPABLE=y When doing TX DMA (e.g. in SPI driver in
+ simplex-tx mode), it should not be necessary to align the data
+ buffers to the cache line.
+ - PR-1103 STM32H7: Resolve clocking and pin configurations bugs that
+ could cause SDMMC and ETH to fail in some configurations
+ - PR-1104 STM32H7: Use UUID for Ethernet MAC. This is inline with the
+ behaviour of STM32F7
+ - PR-1110 STM32H7: Use FDCANSEL to determin FDCAN clock source if
+ possible - PR-1165 STM32H7: SPI transaction appears to be completed
+ before the data has actually been flushed
+ TX DMA completes before the data has been actually sent out from the
+ SPI fifo. This is expected, but the exchange should actually wait for
+ spi tx to finish instead of dma to the fifo to finish. This replaces
+ the dma completion event with the SPI TXC event for detecting end of
+ transmission.
+
+ - PR-1203 PR-1204 STM32H7: Enable support for BDMA and enable it for
+ SPI6
+ - PR-905 x86_64: Resolve linking issue when building with gcc 7 and 9.
+ - PR-904 x86_64: Resolve compiler aliasing warnings and RNG
+ pointer cast bug - PR-944 x86_64: Change entrypoint to standard
+ location 1M
+ - PR-971 x86_64: Fix bug in rng implementation using intrinsics
+ - PR-973 x86_64: Fix crash on boot when XSAVE and SSE/AVX is enabled
+ - PR-974 x86_64: Add support booting NuttX as a Jailhouse Cell
+ - PR-919 sim: Add host mmap and perror to allow use of LIBC_MODLIB
+ and BINFMT_LOADABLE
+ - PR-1198 sim: Use correct errno sign with hostfs interface
+ - PR-932 z16: Updated toolchain to ZDS-II 5.2.2

+ using semaphore in DMA buffer handling code
+ - PR-1221 Add INTx_C macro defintion

+ - PR-1115 SPI slave: Improve interface
+ Enable enqueue and receive full buffers of data with single call, to
+ avoid call overhead when sending / receiving large amounts of data.
+ Enable the slave device to leave received data in the controller
+ receive buffers and retrieve it from there by polling
+ - PR-1196 Audio: Add support for using ap_buffer_info without
+ CONFIG_AUDIO_DRIVER_SPECIFIC_BUFFERS and return ENOTTY if provided ioctl
+ is not supported
+ - PR-1222 audio/cxd56: Add audio buffering feature.
+
+ * Board Support:
+ * Significant Improvements:
+
+ - PR-1200 The boards_button_initialize and boards_userled_initialize
+ functions now return the number of buttons and leds, thus their
+ prototypes have changed from:
+ void board_button_initialize(void)

+ - PR-1051 ST Micro B-G474E-DPOW1 Discovery Kit
+ Initial support for the ST Micro B-G474E-DPOW1 Discovery Kit with

+ a functional NSH prompt. Other peripherals on the board are not yet
+ supported or not tested yet. Contributions to enable other peripherals
+ are welcome. The NSH prompt can be accessed from a host computer via a
+ Virtual COM Port over the same Micro-USB Type B connection used for
+ programming/debugging.
+ - PR-1211 STM32F411-Minimum board (a.k.a. BlackPill)
