* posix: fix warnings with mmap from heap/wkspaceGedare Bloom2017-07-242-2/+2
| | | | | | Avoid void pointer arithmetic. Updates #2859.
* posix: replace mmap mappings lock with libio lockGedare Bloom2017-07-243-86/+13
| | | | | | Use the libio mutex lock instead of the mmap mappings lock. Updates #2859.
* posix: Use unprotected chain operationsSebastian Huber2017-07-202-2/+2
| | | | | | Operarations are already protected by mmap_mappings_lock. Updates #2859.
* Fixed issue with searching mapped addressesKevin Kirspel2017-07-201-3/+4
| | | | | | | | | | The loop that checks if the current address is already mapped uses the same local variable for the chanin node as the newly allocated chain node so the allocated chain node gets over written. Added a new local variable for the loop that checks the address Updates #2859.

* sparc: Add assembly workaround for LEON3FT B2BST errataDaniel Cederman2017-07-173-0/+33
| | | | | | | | | | | | | | | This patch adds NOP instructions to prevent instruction sequences that are sensitive to the LEON3FT B2BST errata. See GRLIB-TN-0009: "LEON3FT Stale Cache Entry After Store with Data Tag Parity Error" for more information. The sequences are only modified if __FIX_LEON3FT_B2BST is defined. The patch works in conjunction with the -mfix-ut700, -mfix-gr712rc, and -mfix-ut699 GCC flags that prevents the sensitive sequences from being generated. Update #3057.
* posix/mmap: Add support for file handler and MAP_ANONKevin Kirspel2017-07-1434-113/+312
| | | | | | | | | | | Added a mmap file handler to struct _rtems_filesystem_file_handlers_r. Updated each file handler object to support the default mmap handler. Updated mmap() to call the mmap handler for MAP_SHARED. Added a mmap file handler for shm Added support for MAP_ANON in mmap(). Updates #2859

| | | | | | | This mechanism can be used to safely move the interrupt server from one scheduler instance to another for example. Update #3071.

* score: Make EDF the default SMP schedulerSebastian Huber2017-07-101-2/+2
| | | | | | | | | | | | | The EDF SMP scheduler supports simple thread processor affinities (see #3059) with a small run-time overhead. The current default SMP scheduler lacks support for thread processor affinities at all. The EDF SMP scheduler offers a good feature set for most applications. So, use it by default. Run-time libraries like libgomp, MTAPI, work stealing schedulers, language interpreters (e.g. Erlang virtual machine), maintainence of per-processor data (e.g. Universal Memory Allocator (UMA)), etc. use a one-to-one thread processor affinity for example. Update #3063.
* score: Fix set schedulerSebastian Huber2017-07-101-5/+13
| | | | | | | Ensure that the thread processor affinity fits the new scheduler instance. Update #3059.

* score: Fix default set affinitySebastian Huber2017-07-071-4/+3
| | | | | | | | The set of online processors must be a subset of the thread processor affinity for the schedulers without arbitrary processor affinity support to avoid problems in case of processor addition and removal. Update #3059.

| | | | | | | | Account for the thread processor affinity and make sure that it is possible to allocate a processor to each thread dedicated to a scheduler instance. Update #3059.

| | | | | | | | Implement the Processor_mask via <sys/bitset.h>. Provide _Processor_mask_To_uint32_t() to enable its use in device specific routines, e.g. interrupt affinity register in an interrupt controller. Update #3059.

* arm: Fix ARMv7-M interrupt processingSebastian Huber2017-07-042-30/+48
| | | | | | | | | | | | Right after a "msr basepri_max, %[basepri]" instruction an interrupt service may still take place (observed at least on Cortex-M7). However, pendable service calls that are activated during this interrupt service may be delayed until interrupts are enable again. The _ARMV7M_Pendable_service_call() did not check that a thread dispatch is allowed. Move this test from _ARMV7M_Interrupt_service_leave() to _ARMV7M_Pendable_service_call(). Update #3060.

* shell: Display scheduler instead of current CPUSebastian Huber2017-06-162-11/+19
| | | | | | | Display the scheduler name instead of the current CPU in the "task" shell command. The current CPU could be misleading in case locking protocols are involved. The "cpuuse" command can be used to obtain the current CPU.
