* score: Avoid some deadlocks in _Once()Sebastian Huber2019-02-183-49/+83
| | | | | | | | Recursive usage of the same pthread_once_t results now in a deadlock. Previously, an error of EINVAL was returned. This usage scenario is invalid according to the POSIX pthread_once() specification. Close #3334.
* libdl/rap: Add the section alloc call after section load was splitChris Johns2019-02-151-0/+6
| | | | Updates #3687
* libdl: Allocator does not unlock and lock memory on loading.Chris Johns2019-02-155-17/+158

* libdl: Add powerpc large memory and small data support.Chris Johns2019-02-0923-129/+1099
| | | | | | | | | | | | | | | | | - Add support for architecure sections that can be handled by the architecture back end. - Add trampoline/fixup support for PowerPC. This means the PowerPC now supports large memory loading of applications. - Add a bit allocator to manage small block based regions of memory. - Add small data (sdata/sbss) support for the PowerPC. The support makes the linker allocated small data region of memory a global resource available to libdl loaded object files. Updates #3687 Updates #3685
* libdl: Add support for large memory programsChris Johns2019-02-0912-433/+648
| | | | | | | | | | | | | | | - Add trampolines to support relocs that are out of range on support architectures. - Support not loading separate text/data sections in an object file if the symbol provided in the section is a duplicate. A base image may have pulled in part of an object and another part needs to be dynamically loaded. - Refactor the unresolved handling to scale to hundreds of unresolved symbols when loading large number of files. Updates #3685
* libdl: Add support for trampolinesChris Johns2019-02-0915-126/+925
| | | | | | | | | | | | | - Trampolines or fixups for veneers provide long jump support for instruciton sets that implement short relative address branches. The linker provides trampolines when creating a static image. This patch adds trampoline support to libdl and the ARM architecture. - The dl09 test requires enough memory so modules are outside the relative branch instruction ranges for the architecture. Updates #3685
* libdl: Fix the support for constructors and desctructors.Chris Johns2019-02-096-59/+144
| | | | | | | - Fix the handling of pending objects. - Add a constructor flags in objects to track then being called. Closes #2921
* libtest/dl08: Add a test for archives.Chris Johns2019-02-091-0/+1
| | | | | | | - Create 2 archives. - Load 1 object file which loads 6 object files from the libraries. Updates #3686
* libdl: Add symbol searching and loading from archives.Chris Johns2019-02-0916-437/+2175
| | | | | | | | | | | | | | - Load archive symbol tables to support searching of archives for symbols. - Search archive symbols and load the object file that contains the symbol. - Search the global and archives until all remaining unresolved symbols are not found. Group the loaded object files in the pending queue. - Run the object file and loaded dependents as a group before adding to the main object list. - Remove orphaned object files after references are removed. Updates #3686

* score: Fix _User_extensions_Thread_switch() (SMP)Sebastian Huber2019-02-081-3/+11
| | | | | We have to read the first node again once we obtained the lock since it may have aready changed.
* score: Fix plain priority thread queues (SMP)Sebastian Huber2019-02-071-0/+8
| | | | We must add/remove the priority queue to the FIFO of priority queues.

* Add low level event recording supportSebastian Huber2019-01-2914-0/+2155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add low level event recording infrastructure for system and user defined events. The infrastructure is able to record high frequency events such as * SMP lock acquire/release, * interrupt entry/exit, * thread switches, * UMA zone allocate/free, and * Ethernet packet input/output, etc. It allows post-mortem analysis in fatal error handlers, e.g. the last events are in the record buffer, the newest event overwrites the oldest event. It is possible to detect record buffer overflows for consumers that expect a continuous stream of events, e.g. to display the system state in real-time. The implementation supports high-end SMP machines (more than 1GHz processor frequency, more than four processors). Add a new API instead. The implementation uses per-processor data structures and no atomic read-modify-write operations. It is uses per-processor ring buffers to record the events. The CPU counter is used to get the time of events. It is combined with periodic uptime events to synchronize it with CLOCK_REALTIME. The existing capture engine tries to solve this problem also, but its performance is not good enough for high-end production systems. The main issues are the variable-size buffers and the use of SMP locks for synchronization. To fix this, the API would change significantly. Update #3665.
* m68k: Avoid _Addresses_Add_offset()Sebastian Huber2019-01-291-4/+2
| | | | | This prevents a cyclic dependency between <rtems/score/cpu.h> and <rtems/score/address.h>.

* riscv: Enable robust thread dispatchSebastian Huber2019-01-091-0/+3
| | | | | | | It must be enabled, since the context switch code does not save/restore the interrupt status. Update #3433.
* Adjust interrupt mode tests for some CPU portsSebastian Huber2019-01-093-3/+7
| | | | | | | In case the robust thread dispatch is enabled by the CPU port, then the interrupt level must not be changed through the task mode. Update #3000.

* tftpfs: Some bug fixesThomas Dörfler2018-12-211-10/+20
| | | | | | | | | | | Fix for: - tftpfs did not mount, when device field in mount entry is empty - tftpfs needs to allocate fs structure before it fills it (avoid use of uninitialized pointer) - tftpfs needs to skip initial slash before hostname
* score: Fix per-CPU data allocationSebastian Huber2018-12-183-29/+49
| | | | | | | | | | | Allocate the per-CPU data for secondary processors directly from the heap areas before heap initialization and not via _Workspace_Allocate_aligned(). This avoids dependency on the workspace allocator. It fixes also a problem on some platforms (e.g. QorIQ) where at this early point in the system initialization the top of the RAM is used by low-level startup code on secondary processors (boot pages). Update #3507.
* config: Remove CONFIGURE_CONFDEFS_DEBUGSebastian Huber2018-12-171-59/+0
| | | | | | | This configuration option was undocumented and not really helpful. To debug issues in <rtems/confdefs.h> it is better to save the preprocessesd file (GCC "-save-temps" option) and use the GCC "-Wp,-dD" pre-processor option.
* build: Remove ampolish3Sebastian Huber2018-12-142-12/+0
| | | | Update #3254.
* score: Static Objects_Information initializationSebastian Huber2018-12-1494-1978/+2018
| | | | | | | | | | | Statically allocate the objects information together with the initial set of objects either via <rtems/confdefs.h>. Provide default object informations with zero objects via librtemscpu.a. This greatly simplifies the workspace size estimate. RTEMS applications which do not use the unlimited objects option are easier to debug since all objects reside now in statically allocated objects of the right types. Close #3621.
* rtems: Use object information to get config maxSebastian Huber2018-12-146-17/+131
| | | | | | | Use functions instead of macros. Add missing rtems_configuration_get_maximum_*() functions. Update #3621.
* score: Remove Objects_Information::auto_extendSebastian Huber2018-12-146-30/+53
| | | | | | | Use Objects_Information::objects_per_block to provide this information. Add and use _Objects_Is_auto_extend(). Update #3621.
* posix: Fix shm_unlink()Sebastian Huber2018-12-111-1/+10
| | | | This function is untested.
* score: Remove Objects_Information::the_apiSebastian Huber2018-12-073-18/+12
| | | | | | | Remove Objects_Information::the_class. This information is already contained in Objects_Information::maximum_id. Update #3621.
* score: Remove Objects_Information::maximumSebastian Huber2018-12-0712-55/+67
| | | | | | | This information is already present in Objects_Information::maximum_id. Add and use _Objects_Get_maximum_index(). Update #3621.
* score: Optimize object lookupSebastian Huber2018-12-0716-77/+84
| | | | | | | | | | | | | | | | Use the maximum ID for the ID to object translation. Using the maximum ID gets rid of an additional load from the object information in _Objects_Get(). In addition, object lookups fail for every ID in case the object information is cleared to zero. This makes it a bit more robust during system startup (see new tests in spconfig02). The local table no longer needs a NULL pointer entry at array index zero. Adjust all the object iteration loops accordingly. Remove Objects_Information::minimum_id since it contains only redundant information. Add _Objects_Get_minimum_id() to get the minimum ID. Update #3621.
* score: Rename Objects_Information::allocation_sizeSebastian Huber2018-12-076-35/+47
| | | | | | | | Rename Objects_Information::allocation_size in Objects_Information::objects_per_block. Adjust integer types in _Objects_Shrink_information() and _Objects_Free(). Update #3621.
