* Update company nameSebastian Huber2023-05-201-1/+1
| | | | | The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
* score: Add SMP scheduler make/clean stickySebastian Huber2021-11-231-0/+1
| | | | | | | | | | | | | | | | | | | | This patch fixes the following broken behaviour: While a thread is scheduled on a helping scheduler, while it does not own a MrsP semaphore, if it obtains a MrsP semaphore, then no scheduler node using an idle thread and the ceiling priority of the semaphore is unblocked for the home scheduler. This could lead to priority inversion issues and is not in line with the MrsP protocol. Introduce two new scheduler operations which are only enabled if RTEMS_SMP is defined. The operations are used to make the scheduler node of the home scheduler sticky and to clean the sticky property. This helps to keep the sticky handing out of the frequently used priority update operation. Close #4532.
* score: Remove unused default scheduler opsSebastian Huber2021-09-211-1/+0
| | | | | | | | | | If SMP support is enabled and the system has exactly one processor, then it may use an uniprocessor scheduler. The ask for help, reconsider help request, and withdraw node operations can be NULL in this case, since they are only used if a thread has at least one helping scheduler node. At least two schedulers are required to get a helping node and each scheduler involved must own at least one processor. This is not possible on a system with exactly one processor.
* score: Provide two thread pin/unpin defaultsSebastian Huber2021-09-211-0/+1
| | | | | | | | | | | | | | The uniprocessor schedulers do not support systems with more than more processors. So they rivially support thread pinning and thus the SMP_FATAL_SCHEDULER_PIN_OR_UNPIN_NOT_SUPPORTED cannot happen. Add a second default implementation for SMP schedulers which do not support thread pinning. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* score: Split SMP multicast action moduleSebastian Huber2021-07-291-0/+3
| | | | | Split up the SMP multicast action module since the use of the SMP multicast action variants depend on the architecture and BSP.
* score: Move per-CPU jobs supportSebastian Huber2021-07-281-2/+2
| | | | Add percpujobs.c to contain the per-CPU jobs implementation.
* build: Alternative build system based on wafSebastian Huber2020-09-141-0/+31
Update #3818.
