-nuttx-6.26 2013-05-15 Gregory Nutt <gnutt@nuttx.org> +6.27 2013-04-28 Gregory Nutt <gnutt@nuttx.org> - * drivers/serial/serial.c: Correct some race conditions when checking - for disconnection of a removable serial device. - * sched/task_posixspawn.c, task_spawn.c, task_spawnparms.c and - spawn_internal.h: Create new interface task_spawn() that is - like posix_spawn(), but uses entry point addresses like - task_create(). - * Corrected all argv[] arguments. Should be char * const *, not - const char **. - * sched/pthread* and include/nuttx/sched: Move pthread join data - and pthread key calculation data into the "task group" structure. - * sched/atexit.c, on_exit.c, task_exithook.c and include/nuttx/sched.h: - Move atexit and on_exit data structures to task group. These - callbacks are only issued now when the final member of the task - group exits. - * sched/waitpid.c, task_exithook.c and include/nuttx/sched.h: - Move waitpid data data structures to task group. Callers of - of waitpid() are now only awakened whent he final thread of the - task group exits. - * sched/mq_descreate.c, mq_open.c, mq_remove.c, group_leave.c, and - include/nuttx/sched.h: Move list of opened message queues to - the task group structures. Now all message queues opened by - members of the group are closed when the last member of the group - exits. - * includes/nuttx/sched.h and Lots of files: Change name of _TCB to - struct tcb_s so that (1) it is consitent with other NuttX naming and - so that (2) the naming can handle some upcoming changes. - * includes/nuttx/sched.h and sched/: There are three TCB structures: - struct tcb_s is a generic common version, struct task_tcb_s is a - version for tasks and kernel threads and pthread_tcb_s is a version - for pthreads. By dividing the TCB structure into these variants, - pthreads do not have to be burdened by task-specific data structures - (and vice versa). - * sched/task_exithook.c adn group_create.c: Fix an error, the - task within the task group may exit early leaving a pthread to - exit the task group last. In this case, we need to remember the - the PID of the main task in the task group and use that PID for - signalling SIGCHILD to the parent task group. - * included/nuttx/sched.h and sched/sig*.c: Numerous changes to the - signal deliver logic so that the delivery of signals to threads - within a task group will be compliant with delivery of signals - to threads within a POSIX process. - * sched/mq_recover.c and task_exithook.c: Add logic to handle the - case where a task is deleted (or pthread canceled) while it is - waiting on a message queue. task_delete() and pthread_cancel() - are dangerous interfaces. This is only one feeble recover measure - of *many* that would be needed to do this safely. - * sched/group_killchildren.c, task_recover.c, group_foreachchild.c, - sched/restart.c, sched/task_delete.c, and others: Beef up logic - to better support task deletion and pthread cancellation. Needed - to pass need OS test case for task_restart(). - * sched/include/sched.h and all timed functions in sched/: Move - timer from local variables to TCB. This is needed so that if a - task is canceled or restarted while it is waiting for a timed - event, we can gracefully recover. We can't let the timer expire - after the task has been deleted. - * arch/arm/include/stm32 and arch/arm/src/stm32: Add support for - the STM32 F3 family (still missing some things). - * configs/stm32f3discovery: This will (eventually) be support for - the STM32F3Discovery board. - * STM32 F3 and STM32F3Discovery port is complete a ready for test. - * arch/arm/src/lpc17xx: Add support for the Cortex-M4 FPU and - Mikes "common vector" logic. The LPC1788 is going to need - these things. - * arch/arm/src/stm32/stm32_spi.c: Fix SPI DMA logic that does - not work if sem_wait() is interrupt by a signal. From Petteri - Aimonen. - * drivers/input/max11802.c: MAX11802: Fix a timing bug that - corrupted coordinates. From Petteri Aimonen. - * drivers/mmcsd/mmcsd_spi.c: Use SPI locking so that MMC/SD can - exist on the same bus as other SPI devices. From Petteri - Aimonen. - * graphics/nxfonts/nxfonts_sans17x22.h: Small mod to hyphen in - sans17x22 font. The hyphen did not have any space on its sides. - This caused it to run together with other characters so that for - example "+-" would look weird. From Petteri Aimonen. - * mm/mm_mallinfo.c: Take MM semaphore in mm_mallinfo. From Petteri - Aimonen. - * configs/stm32f3discovery/nsh/defconfig: Disable SPI. It is not - used. - * drivers/mtd/sst39vf: Add a driver for the SST29VF NOR FLASH parts. - * sched/os_start.c: Add an additional call-out to support board- - specific driver initialization during the start phase: If - CONFIG_BOARD_INITIALIZE is defined, then an additioinal - initialization function called board_initialize() will be called - just after up_initialize() is called and just before the initial - application is started. - * arch/arm/src/stm32/stm32_otgfsdev.c, drivers/usbdev/usbdev_trprintf.c, - and include/nuttx/usb/usbdev_trace.h: Add logic to support decoding - of device-specific trace events to make the trace ouput more readable. - From Petteri Aimonen. - * arch/arm/src/stm32/stm32_otgfsdev.c: Need to manually set CNAK in - the case where we are waiting for a SETUP command with DATA. Otherwise, - the core may NAK further transactions. From Petteri Aimonen. - * arch/arm/src/stm32/stm32_otgfsdev.c: Add logic to prevent premature - to IDLE state. This change (plus the previous) was necessary to get - the CDC/ACM driver working the certain STM32 F4 hardware (but not others). - These changes appear to prevent certain race conditions that may or may - not cause USB problems. From Petteri Aimonen. - * arch/arm/include/armv6-m and arch/arm/src/armv6-m: First cut at support - for the Cortex-M0 - * configs/nutiny-nuc120, arch/arm/include/nu1xx, and arch/arm/src/nuc1xx: - Support for Nuvoton NuTiny NUC120. - * 2013-02-22: the Cortex-M0, NuvoTron NUC1xx, and NuTiny-SDK-NUC120 port - is code complete and ready for testing. - * configs/ekk-lm3s9b96/ostest and nsh: All EKK-LM3S9B96 configurations - converted to use the mconf configuration tool. - * configs/zkit-arm-1769: Add support for Zilogic System's ARM development - Kit, ZKIT-ARM-1769. From Rashid. - * configs/zkit-arm-1769/hello: Add a "Hello, World!" configuration for - the KBIT-ARM-1769 board. From Rashid. - * configs/zkit-arm-1769/thttpd: Add a THTTPD configuration for the - KBIT-ARM-1769 board. From Rashid. - * 2013-02-27: All configurations for the Cortex-M0 NuTINY-SDK-NUC120 - appear to be functional and stable. - * configs/zkit-arm-1769/nsh: Add an NSH configuration for the - KBIT-ARM-1769 board. From Rashid. - * arch/arm/src/stm32/stm32_otgfsdev.c: Fixes from Petterri Aimonen - related to corner cases that can cause infinite interrupts. - * drivers/usbdev/usbmsc_scsi.c: Change to allow the full name in the - USB descriptor but a truncated, 8-byte name in the SCSI field. - From Petteri Aimonen. - * arch/arm/src/stm32/stm32_spi.c: Need to clear error flags to prevent - corruption of subsequent transfers. Also, bit count should not be - changed while the SPI peripheral is enabled. From Petteri Aimonen. - * drivers/mmcsd/mmcsd_spi.c: When bus is shared, the speed has to be - set every time. Also SD cards require a few dummy clocks to react - into CS release. From Petteri Aimonen. - * configs/lm4f120-launchpad: In initial configuration for testing - the LM4F120 LaunchPad port. This is to support testing only and - is not yet a functional board port (as of 2013-03-01). - * arch/arm/include/lm/lm4f_irq.h and arch/arm/src/lm/chip/lm4f_vector.h: - Add interrupt vector/IRQ number definitions for the LM4F120. - * arch/arm/src/stm32f20xxx_dma.c and stm32f40xxx_dma.c: Fix a typo - in assigned base register addresses for each DMA channel. From - Yan T. - * Several build fixes from Mike Smith were incorporated. These were - mostly compilation errors introduced into the system because of the - large number of recent changes with broad scope (2013-03-04). - * configs/zkit-arm-17969/src/up_can.c: Add CAN support to the - Zilogics Technologies ZKIT-ARM-1769 board (From Rashid Fatah, (2013-03-04)). - * arch/arm/src/lpc17/lpc17*_clockconfig.c: The WaveShare Open1788 - board now boots and passes the OS test. This is the work of - Rommel Marcelo (2013-03-04). - * arch/arm/src/lm/lm_gpio.c, lm_gpio.h, and chip/lm4f_pinconfig.h - Extend GPIO logic to handle LM4F. Add LM4F pin configuration header - file (2013-03-04). - * configs/open1788: Enable LED support in all configurations. - (2013-03-04) - * configs/open1788/nsh: NSH configuration verified function. By Rommel - Marcelo (2013-03-05). - * configs/open1788/src/lpc17_nsh.c: Use the SD card interface, not SPI - to interface with SD cards (2013-03-05. - * arch/arm/src/lpc17xx/lpc17_sdcard.c and header files: Clone the STM32 - SD card interface to the LPC1788. It appears to be the same IP. - (2013-03-05) - * libc/wqueue: Work queue logic moved from sched/ to libc/wqueue. It - is not really core OS functionality and this move helps prepare for - user-space work queues. (2013-03-05) - * libc/wqueue: Implemented user-space work queues. These will not - get tested until the next time I attempt a NuttX kernel build. - (2013-03-05). - * arch/arm: Correct some bad syscall dispatching logic. This change - cannot be fully tested until there is a fielded NuttX kernel build. - (2013-03-06). - * net/net_poll.c: Correct logic that checks if the socket is - disconnected when the poll is setup. That is bad logic: Listen - sockets, for example, are not connected. In that case, the purpose of - the poll is to wait for connection events. As a result of this, - poll/select would return immediately with POLLHUP with it was used to - detect connection events. This fix for now was to check instead if - the socket is closed (meaning that it was connected at one time but - was closed by the remote peer). That excludes the listen socket which - was never connected. This does introduce a new problem, however. If - the socket was not closed, but lost the connection through an abnormal - event, then poll/select will hang. That needs to be revisited. - (2013-03-07) - * fs/fs_select.c: Was not checking if the timeout parameter was NULL - but would, instead, setup a bogus timeout based on whatever it found at - address zero. Also, improved some of the memory allocation logic so - that it will not use so much memory. (2013-03-07) - * net/net_poll.c: Handle the missing case. Now tests for not connected - AND not listening. I think that now covers all of the cases including - the missing case noted above. (2013-03-07) - * mm/: Move all memory manager globals into a structure. A reference - to this structure is now passed internally between mm APIs. This - change will (eventually) support multiple heaps and heap allocators. - (2013-03-08). - * mm/ and include/nuttx/mm.h: Implement support for multiple heaps. - (2013-03-08). - * arch/*/src: xyz_addregion() needs to call kmm_addregion, not mm_addregion. - (2013-03-08). - * sched/kmm*.c: Move this garbage kmm*.c file to mm/. until I decide what - to do with them (which is probably to just delete them). (2013-03-08). - * mm/mm_test.c and Makefile.test: Deleted the memory test. This was - a good test and helped me a lot when I wrote the memory manager, but - now it is in the way and paralyzing other efforts. So the memory unit - test was deleted. (2013-03-08) - * sched/sched_free.c: Rename sched_free() to sched_ufree(); Add - sched_kfree() to handler deferred kernel heap allocations. (2013-03-10) - * arch/: User user-accessible heap to allocate all stacks. (2013-03-10) - * arch/arm/src/sam3u: The AT91SAM3U will now support a kernel heap if - so configured. (2013-03-10) - * configs/sam3u-ek/knsh: This configuration was converted to use the - kconfigs-frontends build tool. (2013-03-10) - * configs/*/include/user_map.h and include/nuttx/userspace.h: Remove - the very kludgy user_map.h file and replace it with a header that - is expected at the beginning of the user-space blob.

If %n occurs in + the format statement after the input data stream has been fully + parsed, the %n format specifier will not be handled. Reported by + Lorenz Meier (and also earlier by Kate) (2013-03-17). + * drivers/serial/serial.c: Support for O_NONBLOCK was not supported + in the "upper half" serial driver.

Only the prototypes were changed on this + big, initial checkin. The next step will be to add logic to + allocate stacks for kernel threads from protected kernel memory + and all other task types from unprotected user memory (2013-03-20). + * arch/*/src/common/up_createstack.c, up_use_stack.c, and + up_release_stack.c: If creating or releasing the stack for a kernel + thread, use the kernel allocator so that the kernel thread stacks + are protected from user application meddling (2013-03-20). + * arch/arm/src/armv[6|7]-m/up_scall.c: Fix parameter passing for + all system call inline functions with > 3 parameters (2013-03-20) + * arch/*/src/common/up_stackframe.c and include/nuttx/arch.h: Add + and new interface to set aside memory on the stack. This will be + used at least in the kernel build to hold task arguments (2013-03-21). + * sched/sig_deliver.c: When dispatching signals to user threads, + copy the siginfo_t from the sigq to the stack.

Consequently, if the action event handler tried - to stop the timer, the request would be ignored. Changes the order - so that the timer is re-enabled before the callback. There is still - no risk of re-entrancy, because everything executes on the USRWORK work - queue. From Petteri Aimonen. - * NxWidgets::CMultiLineTestBox: Fix text placement error. From Petteri - Aimonen. - * NxWidgets::CWidgetControl: Added another semaphore, boundssem, which - is set as soon as the screen bounds are known. This corrects two - problems: - 1) Due to the way nxgl_rectsize computes the size, it will never - be 0,0 like CWidgetControl expects. Therefore the size is considered - valid even though it has not been set yet. - 2) After the check is fixed to test for > 1, NxWM window creation will - hang. This is due to the fact that it uses the screen bounds for - determining window size. This was being blocked on geosem, which - is only posted after the size has been set. - From Petteri Aimonen. - * NxWidgets::CImage: Two enhancements: - 1) Allow changing the bitmap even after the control has been created. - 2) Allow giving 'null' to have the control draw no image at all. - From Petteri Aimonen. - * NxWM::CTaskBar: Allow windows with null icon.

From Petteri Aimonen. - * NwWM::CStartWindow, NxWM::CWindowMessenger: Get rid of the start window - thread. Instead, handle all events through the USRWORK work queue. - For me, this was necessary because I would open some files in button - handlers and close them in NxTimer handlers. If these belonged to - different tasks, the close operation would fail. Further benefits: - + Gets rid of one task and message queue. - + Reduces the amount of code required - + Decouples CStartWindow from everything else - now it is just a window - with application icons, not an integral part of the event logic. - + All events come from the same thread, which reduces the possibility of - multithreading errors in user code. - + The user code can also send events to USRWORK, so that everything gets - serialized nicely without having to use so many mutexes. - Drawbacks: - - Currently the work state structure is malloc()ed, causing one allocation - and free per each input event. Could add a memory pool for these later, but - the speed difference doesn't seem noticeable. - - The work queue will add ~50 ms latency to input events. This is however - configurable, and the delay is anyway short enough that it is unnoticeable. - From Petteri Aimonen. + * NxWidgets bitmap_converter.py: Fix bug when image width > 255.
