* Use a common phrase for pointer parametersSebastian Huber2021-06-1514-181/+180
| | | | | | | Mention the type of the pointer in the parameter description. Use the more general term "object" instead of "variable". Update #3993.
* score: Add PER_CPU_DATA_NEED_INITIALIZATION()Sebastian Huber2021-06-108-55/+118
| | | | | | | | | Make the initialization of the per-CPU data optional. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* splinkersets01: Test linker sets in librarySebastian Huber2021-06-107-7/+66
| | | | | Make sure that the linker sets work if placed in a library (this is how they are used in RTEMS).
* bsps/sparc: Simplify memory initializationSebastian Huber2021-06-102-34/+39
| | | | | | | | | | | | | Directly initialize the memory in the start sequence defined by start.S instead of using a system initialization handler. This avoids using the global variable rdb_start which used a memory location which was shared with _ERC32_MEC_Timer_Control_Mirror. This change makes it possible to use _Memory_Allocate() even before the system initialization is started. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* bsps/sparc: Simplify stack initializationSebastian Huber2021-06-101-28/+21
| | | | | | Initialize the stacks for all processors in one place. Do not rely on Per_CPU_Control::interrupt_stack_high and directly use the statically allocated interrupt stack area.
* bsps/sparc: Unify stack initializationSebastian Huber2021-06-101-8/+6
| | | | | Initialize the stacks in start.S in one place and identical to _CPU_Context_Initialize().
* bsps/sparc: Remove support to load data sectionSebastian Huber2021-06-101-32/+4
| | | | | | | | | | | | | | | | | | Remove the support to load the data section and rely on the boot loader. The code is an artifact from the old erc32 days, when we would boot and execute from ROM and the .data had to be copied over to RAM. With leon1/2/3, this is not used anymore as a boot loader is made from the RAM image using a custom tool (mkprom). In SMP configurations, this support was also broken since LEON3_Boot_Cpu (in the data section due to the -1 initialization value) was used quite early in the start sequence. If the data copy is really necessary, then an application can still add this step as a very early system initialization step, since boot_card() and the system initialization loop does not use initialized read-write data (only read-only and BSS data). However, the SMP startup would still not work in this case. A boot loader is a better place to load the sections.
* bsps/sparc: Remove unused __bsp_mem_init symbolSebastian Huber2021-06-101-1/+1

* score: Fix initialization of thread queue contextSebastian Huber2021-06-106-9/+15
| | | | | | | Set Thread_queue_Context::timeout_absolute in _Thread_queue_Context_set_timeout_argument() to avoid using it uninitialized. The bug was introduced by a89ecaa1a94d49ddae7753d6b83923e9d2a00486.
* sysconf: Remove sysconf(515)Ryan Long2021-06-092-12/+0
| | | | | | | GCC originally needed this 20 years ago. No longer needed, so it is being removed. Closes #4391
* main_edit.c: get rid of malloc warningRyan Long2021-06-091-8/+8
| | | | | | A warning was present when building RTEMS that stated that the argument for malloc() exceeded the maximum object size. To get rid of this, I changed many places where 'int' was being used to 'size_t'.
* aarch64: add qemu bsps for cortex-a72Gedare Bloom2021-06-0918-0/+749
| | | | The a72 BSPs are identical to the a53 BSPs just changing a53 to a72.
* futimens.c, utime.c: Remove unnecessary include of <sys/stat.h>.Joel Sherrill2021-06-092-2/+0
|
* fsnofs01/init.c: Check for ENOENT from utime().Joel Sherrill2021-06-081-3/+6
| | | | | | The addition of the entire *utime*() family of functions resulted in this call returning ENOENT not ENXIO. This is better aligned with the POSIX definition of the methods.

| | | | | | Improved tests for utime() and utimes() and update license. Close #4399
* libcsupport: Implement utimes() in terms of utimensat()Ryan Long2021-05-281-14/+49
| | | | | | | | | utimes() now calls utimensat() to update file access and modification timestamps. Updated license. Closes #4398
* libcsupport: Implement utime() in terms of utimensat()Ryan Long2021-05-281-32/+40
| | | | | | | | | 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

| | | | | | 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

* 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

* 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.

* 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.
