| | | | | | | | | Clock disciplines may be WATCHDOG_RELATIVE, WATCHDOG_ABSOLUTE, or WATCHDOG_NO_TIMEOUT. A discipline of WATCHDOG_RELATIVE with a timeout of WATCHDOG_NO_TIMEOUT is equivalent to a discipline of WATCHDOG_NO_TIMEOUT. updates #2732

* libdl/rtl-obj.c: synchronize cache after code relocation.Pavel Pisa2016-07-214-2/+74
| | | | | | | | Memory content changes caused by relocation has to be propagated to memory/cache level which is used/snooped during instruction cache fill. Closes #2438

* score: Postpone SMP shutdown in _Terminate()Sebastian Huber2016-07-062-4/+7
| | | | | This enables fatal extensions to continue program execution after some fatal errors.
* score: Do not disable ISR in _Terminate()Sebastian Huber2016-07-062-9/+1
| | | | | | | This partially reverts 38ee75853f674977609bd078c69fb53420afdd08. Let the calling context decide if interrupts must be disabled or not. The goal is to enable fatal extensions to continue program execution after some fatal errors.
* libdl/rtl-obj.c: ensure that loaded code is synchronized through caches.Pavel Pisa2016-07-041-0/+2
| | | | | | | | | | | | Synchronize each cluster of sections of the same type separately to support even cases where text and data are allocated from different areas (for example due allocation from different MPU protection regions). rtems_cache_instruction_sync_after_code_change is called even to data sections. Propagation of data only changes should not require cache maintenance operation on sane SMP mutithread capable systems if barrier instruction is added but be on safe side even for case where self modifying code uses data sections initial values etc.
* rtems+bsps/cache: Define cache manager operations for code synchronization ↵Pavel Pisa2016-07-042-1/+30
| | | | | | | | | | | | | | and maximal alignment. There is need for unambiguous named and defined cache function which should be called when code is updated, loaded or is self-modifying. There should be function to obtain maximal cache line length as well. This function can and should be used for allocations which can be used for data and or code and ensures that there are no partial cache lines overlaps on start and end of allocated region.
* score/arm: Ensure that copile time alignment is 64 bytes for Cortex-A multilib.Pavel Pisa2016-07-042-2/+9
| | | | | Some/many Cortex-A cores have data cache line length 64 bytes and maximum value has to be used for system structures alignment.
* arm/score and shared: define ARM hypervisor mode and alternate vector table ↵Pavel Pisa2016-07-041-0/+1
| | | | | | | | | base access. The main reason for inclusion of minimum hypervisor related defines is that current ARM boards firmware and loaders (U-boot for example) start loaded operating system kernel in HYP mode to allow it take control of virtualization (Linux/KVM for example).
* net: Fix byte order issue for getnameinfo()Sebastian Huber2016-07-011-4/+2
|
* score: Change scheduler node init and destroySebastian Huber2016-07-0123-64/+107
| | | | | | Provide the scheduler node to initialize or destroy to the corresponding operations. This makes it possible to have more than one scheduler node per thread.
* score: Fix MPCI message layoutSebastian Huber2016-07-011-1/+1
| | | | | | | | Restore the 32-bit priority field in MP_packet_Prefix. Bug introduced by 254dc82daf8cbd6922376fcbb81c31e21cbf4d16. Close #2750.
* rtems: Fix rtems_task_set_scheduler() APISebastian Huber2016-07-014-58/+89
| | | | | | | | | | | Task priorities are only valid within a scheduler instance. The rtems_task_set_scheduler() directive moves a task from one scheduler instance to another using the current priority of the thread. However, the current task priority of the source scheduler instance is undefined in the target scheduler instance. Add a third parameter to specify the priority. Close #2749.
* score: Workaround for #2751Sebastian Huber2016-07-011-0/+4
| | | | | | | | | | | | | | | The ARM and PowerPC interrupt epilogues call _Thread_Dispatch() with interrupts disabled (counter example: SPARC). On SMP configurations, since inter-processor interrupts set the thread dispatch necessary indicator this prevents a thread dispatch notification in post-switch handlers (which all run with interrupts disabled). On all configurations, this is a serious issue for the interrupt latency. Update #2751
* score: Next try to fix thread lock on SMPSebastian Huber2016-07-011-6/+16

* score: Fix priority affinity SMP schedulerSebastian Huber2016-07-011-2/+10
| | | | Bug introduced by 9bfad8cd519f17cbb26a672868169fcd304d5bd5.
* score: Strong APA scheduler processor allocationSebastian Huber2016-06-303-24/+24
| | | | | Use _Scheduler_SMP_Allocate_processor_exact() to prevent unexpected migrations.
* score: Avoid atomic fences for thread wait flagsSebastian Huber2016-06-307-34/+37
| | | | | The use of atomic fences is brittle and may break due to changes in different areas which is hard to manage.
* score: Fix thread lock on SMP configurationsSebastian Huber2016-06-304-12/+46

* score: _CPU_SMP_Send_interrupt() documentationSebastian Huber2016-06-291-4/+0
|
* score: Fix SMP message handlingSebastian Huber2016-06-295-28/+37
| | | | | | | | According to the C11 standard only atomic read-modify-write operations guarantee that the last value written in modification order is read, see "7.17.3 Order and consistency". Thus we must use a read-modify-write in _SMP_Inter_processor_interrupt_handler() to make sure we read an up-to-date message.
* libnetworking: Import current <sys/socket.h>Christian Mauderer2016-06-281-73/+373
| | | | | Import the <sys/socket.h> from current FreeBSD. This allows to build some current software (e.g. libressl).

* libnetworking: Add <machine/_align.h>Christian Mauderer2016-06-283-1/+29
| | | | This is necessary for new <sys/socket.h>.
* libnetworking: Import current <arpa/inet.h>Christian Mauderer2016-06-289-38/+73
| | | | | | | | | | Import the <arpa/inet.h> from current FreeBSD. Necessary due to changes in <netinet/in.h>. Remove BSD hack from <arpa/inet.h>. Clean up problems with htonl(). These functions are defined in <arpa/inet.h>. This lead to some problems because they are defined in <rtems/endian.h> too. Add NTOHL, ... to <rtems/rtems_bsdnet_internal.h>.
* libnetworking: Import current <netinet/in.h>Christian Mauderer2016-06-2818-135/+443
| | | | | | | | | | | | | | | | Import the <netinet/in.h> from current FreeBSD. This allows to build some current software (e.g. libressl). Add legacy support like * prototype for in_cksum(), * IPPORT_USERRESERVED, * deprecated IPCTL_RT* defines, * ip_fw_chk_t and ip_fw_ctl_t, * ip_nat_... (IP NAT hooks), and * IP_NAT option for get/setsockopt() to new <rtems/rtems_netinet_in.h>.
* libnetworking: Import current <netinet6/in6.h>Christian Mauderer2016-06-283-0/+760

* libnetworking: Import <sys/_sockaddr_storage.h>Christian Mauderer2016-06-283-1/+60
| | | | | Import the <sys/_sockaddr_storage.h> from current FreeBSD. Necessary for <netinet/in.h> update.
* libnetworking: Add minimal getnameinfo()Christian Mauderer2016-06-282-1/+62
| | | | | | | This implementation just falls back to giving a string representation of the IP. It supports IPv4 only. Add test for getnameinfo().
* libnetworking: Import current <netdb.h>Christian Mauderer2016-06-287-52/+212
| | | | | | | | | | | | Import the <netdb.h> from current FreeBSD. This allows to build some current software (e.g. libressl). Add __h_errno(). Update gethostent_r() API. Linux and FreeBSD use a common API now. Adapt the RTEMS one to provide the same one. Match gethostbyname_r() with prototype.
* libnetworking: Add <rtems/rtems_netdb.h>Christian Mauderer2016-06-2813-22/+66
| | | | | Move prototypes of non-portable _get*by*name/addr and _set/end*ent functions. This makes it easier to update <netdb.h>.
* libcsupport: Add dummy for setgroups().Christian Mauderer2016-06-282-1/+27
| | | | | The dummy for setgroups() allows applications using it to build (for example civetweb webserver).
* score: Change Priority_Control to 64-bitSebastian Huber2016-06-2410-19/+26
| | | | | | | | A 32-bit Priority_Control limits the uptime to 49 days with a 1ms clock tick in case the EDF scheduler is used. Increase it to 64-bit to enable proper operation of the EDF scheduler, Close 2173.
