| | | | | | | | | utime() now calls utimensat() to update file access and modification timestamps. Updated license. Closes #4397
* libcsupport: Added futimens() and utimensat()Ryan Long2021-05-287-15/+494
| | | | | | | | | | Created futimens.c and utimensat.c to add support for the POSIX methods futimens() and utimensat(). utime() and utimes() are considered obsolote by POSIX, but RTEMS will continue to support them. Closes #4396

* thread-API: Add rtems_*mutex_try_lockChristian Mauderer2021-05-282-0/+91
| | | | | | This adds a rtems_mutex_try_lock and a rtems_recursive_mutex_try_lock. Update #4440.
* cpukit: Add description of release version numbersChristian Mauderer2021-05-281-0/+21
| | | | | The release version in the git sources doesn't change. Add a note why that is the case.
* score: Add RTEMS_UNREACHABLE() to a groupSebastian Huber2021-05-281-0/+2

* spec/aarch64: Add BSPs for real ZynqMP hardwareKinsey Moore2021-05-277-2/+85
| | | | | | | Add the BSPs for running on the ZU3EG Ultrascale+ Zynq MPSoC and alter the option defaults necessary for them to run properly using the standard BOOT.BIN configured for PetaLinux that comes in the Out-of-Box package.
* bsps/aarch64: Add MMU driver to relax alignmentKinsey Moore2021-05-2711-20/+603
| | | | | | | | | | | | | | | Currently, the AArch64 BSPs have a hard time running on real hardware without building the toolchain and the bsps with -mstrict-align in multiple places. Configuring the MMU on these chips allows for unaligned memory accesses for non-device memory which avoids requiring strict alignment in the toolchain and in the BSPs themselves. In writing this driver, it was found that the synchronous exception handling code needed to be rewritten since it relied on clearing SCTLR_EL1 to avoid thread stack misalignments in RTEMS_DEBUG mode. This is now avoided by exactly preserving thread mode stack and flags and the new implementation is compatible with the draft information provided on the mailing list covering the Exception Management API.
* bsps/a53: Increase available RAMKinsey Moore2021-05-271-1/+1
| | | | | | | The default available RAM on the A53 BSP is quite small at 8MB. This bumps that to 128MB to avoid allocation failures in tmcontext01 caused by large allocations on a cache size of 16MB reported by the system registers in QEMU.
* bsps/aarch64: Advertise cache function supportKinsey Moore2021-05-271-0/+10
| | | | | Ensure that cache functions are flagged as usable by the generic cache implementation code.
* bsps/aarch64: Align MVAs consistentlyKinsey Moore2021-05-271-8/+5
| | | | | | This fixes a bug where addresses were not being aligned correctly. Addresses used in cache functions are now aligned consistently using RTEMS_ALIGN_DOWN.
* bsps/aarch64: Break out system registersKinsey Moore2021-05-273-180/+10019
| | | | | Break out system register definitions and accessors so that they're usable by other parts of RTEMS.
* rtems: Document new rtems_task_delete() errorSebastian Huber2021-05-271-0/+3
| | | | Update #4414.
* cpukit/libpci: fix potential buffer overflow in pci_cfg_print_code.cHarrison Edward Gerber2021-05-261-2/+2
| | | | | | See also CID 1399721 Closes #4442
* score/aarch64: Align context validation frameKinsey Moore2021-05-261-11/+18
| | | | | | Ensure the stack remains aligned by keeping the context frame at a multiple of 16 bytes. This avoids stack alignment exceptions which occur when the stack pointer is not 16 byte aligned.
* score: Direct thread dispatch in a self restartSebastian Huber2021-05-261-5/+11
| | | | | | | | | | Commit 73ebf9a27ed5cd0fd3e0dc0da98345d7faa610a2 accidentally removed the direct thread dispatch in a self thread restart. In case of a self restart (always in task context) the directive shall not return. If this is not possible due to a bad thread dispatch disable level, then a fatal error shall occur. Update #4412.
* score: Fix _Thread_Cancel()Sebastian Huber2021-05-261-26/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The _Thread_Cancel() (in contrast to _Thread_Restart() which used a similar code block) may have produced ready threads with an active timer in case the thread to cancel had its thread life protection enabled. The problem was this code block: Priority_Control priority; _Thread_Add_life_change_request( the_thread ); if ( _Thread_Is_life_change_allowed( previous ) ) { _Thread_State_release( the_thread, &lock_context ); _Thread_queue_Extract_with_proxy( the_thread ); _Thread_Timer_remove( the_thread ); } else { _Thread_Clear_state_locked( the_thread, STATES_SUSPENDED ); _Thread_State_release( the_thread, &lock_context ); } priority = _Thread_Get_priority( executing ); _Thread_Raise_real_priority( the_thread, priority ); _Thread_Remove_life_change_request( the_thread ); The life change request should only be added/removed if a life change is allowed (see _Thread_Restart()). Add _Thread_Try_life_change_request() and use it in _Thread_Cancel() and _Thread_Restart(). Close #4435.
* posix: Allow pthread_cancel() from within ISRsSebastian Huber2021-05-262-40/+49
| | | | Close #4413.
* score: Simplify calling _Thread_Exit()Sebastian Huber2021-05-266-53/+28
| | | | | Move common code into _Thread_Exit(). This enables a tail call optimization in most cases.
* rtems: Return RTEMS_CALLED_FROM_ISRSebastian Huber2021-05-261-5/+15
| | | | | | | If rtems_task_delete() is called from within interrupt context, then return RTEMS_CALLED_FROM_ISR. This makes the behaviour predictable. Update #4414.
* sysinit: Do not open console when just referencing reentrancy structure.Joel Sherrill2021-05-252-6/+21
| | | | | | | | | This change eliminates a system initialization dependentcy which resulted in an application without a file system or console referencing errno being forced to include the code to open(/dev/console), close(), atexit(), and the unmount infrastructure. Closes #4439.
* powerpc/.../sbrk.c: Do not reference errno.Joel Sherrill2021-05-251-2/+12
| | | | Closes #4r37.
* ppc-irq-legacy.c: Use rtems_malloc() instead of malloc().Joel Sherrill2021-05-251-10/+11
| | | | Closes #4438.
* telnetd.c: Remove RTEMS_NETWORKING checkVijay Kumar Banerjee2021-05-201-10/+1
| | | | Set the priority manually to make telnetd compatible with the
* testsuites: Remove telnetd01Vijay Kumar Banerjee2021-05-205-179/+0
| | | | | telnetd01 test cannot be run without a network stack, so this test is being moved to the rtems-net-legacy repository.
* score: Simplify thread queue timeout handlingSebastian Huber2021-05-1810-44/+88
| | | | | | | Add Thread_queue_Context::timeout_absolute to specify an absolute or relative timeout. This avoid having to get the current time twice for timeouts relative to the current time. It moves also functionality to common code.
* posix: Fix use of clock for relative timesSebastian Huber2021-05-181-13/+18
| | | | Close #4426.
* score: Add _CPU_Context_switch_no_return()Sebastian Huber2021-05-1810-5/+58
| | | | | | | | | | | The __builtin_unreachable() cannot be used with current GCC versions to tell the compiler that a function does not return to the caller, see: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99151 Add a no return variant of _CPU_Context_switch() to avoid generation of dead code in _Thread_Start_multitasking() if RTEMS was built with SMP support enabled.
* score: Move _Thread_queue_Queue_get_name_and_id()Sebastian Huber2021-05-174-36/+78
| | | | | | | | | | Move this diagnostic function to a separate file since it does not provide a core function of the system. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* posix: Use RTEMS_POSIX_API in clock_nanosleep()Sebastian Huber2021-05-171-0/+5
| | | | | It is only possible to get interrupted by a POSIX signal if RTEMS_POSIX_API is defined.
* posix: Move clock_nanosleep()Sebastian Huber2021-05-174-91/+118
| | | | | | | Move clock_nanosleep() to a separate file to avoid a dependency on errno which pulls in the Newlib reentrancy support. This is an issue since most parts which are pulled in cannot be garbage collected by the linker due to the system initialization linker set.
* bsps/imxrt: Enable DMA clockChristian Mauderer2021-05-171-0/+3
| | | | | | The EDMA is intialized so make sure the the clock is initialized too. Update #4180
* bsps/imxrt: Fix OCRAM, ITCM and DTCM sizesChristian Mauderer2021-05-1710-4/+119
| | | | | | | | | | | | The sizes are configurable via fuses or per software via some registers. At the moment the registers are not changed. Changing the registers destroys data stored in the RAM areas (like application code or data). So either the fuses or some bootloader should be used to set them before the application starts. This also adds an OCRAM only linker command file. Update #4180
* bsps/imxrt: Add addresses and interrupts to dtsChristian Mauderer2021-05-172-521/+1651
| | | | | | | | Add addresses and interrupts for most internal peripherals to the dts. The additional aliases make it possible for an application to easily access these informations. Update #4180
* bsps/imxrt: Reduce devicetree sizeChristian Mauderer2021-05-172-765/+472
| | | | | | | Remove symbols that would be necessary for overlays and decrease padding that would be necessary for adding stuff during run-time. Update #4180
* bsps/imxrt: Fix documentation errorChristian Mauderer2021-05-171-1/+1
| | | | Update #4180
* score: Add and use _Per_CPU_Is_ISR_in_progress()Sebastian Huber2021-05-174-13/+22
| | | | | Add _Per_CPU_Is_ISR_in_progress() as an optimized version of _ISR_Is_in_progress().
* score: Improve parameters in _Thread_Change_life()Sebastian Huber2021-05-172-22/+29

* arm/altera-cyclone-v: Fix compile errorSebastian Huber2021-05-171-2/+2
| | | | Update #4406.
* rtems: Fix task restart within interrupt contextSebastian Huber2021-05-143-74/+17
| | | | | | | | | | | rtems_task_restart() may be called from within interrupt context. So checking only that the thread to restart is equal to the executing thread is insufficient to determine a self restart. We have to also check that no ISR is in progress. Merge _Thread_Restart_other() and _Thread_Restart_self() into one _Thread_Restart() since they share a lot of common code. Close #4412.
* rtems: Always set the real priority during restartSebastian Huber2021-05-141-26/+32
| | | | | | | Unconditionally set the real priority of the task to its initial priority during a task restart. Close #4411.
