Project:Branches: sebhub/rtems:up/posix-sporadic to rtems/rtos/rtems:main Author: Sebastian Huber Assignee: Sebastian Huber Reviewer: Matteo Concas Issue #5745: The sporadic server breaks a scheduler change on a uniprocessor Issue #5788: psx09 always fails in unicore configurations On a uniprocessor, `_Scheduler_Set()` extracted the real priority node of a sporadic server thread at the low priority. The node sits in no tree then. psx09 hides this defect because it first asks for the scheduler of processor 1, which a uniprocessor does not own. | Commit | Change | | --- | --- | | score: Inhibit a scheduler change without SMP | enables the scheduler change inhibitors wherever the POSIX API is enabled | | psxtests/psx09: Use a scheduler which exists | asks for the scheduler of the last processor | `rtems_task_set_scheduler()` returns `RTEMS_RESOURCE_IN_USE` for a sporadic server thread at both priorities on a uniprocessor. An SMP build already does this. At the high priority, the directive returned `RTEMS_SUCCESSFUL` before this series. ## Test Built with GCC 15.2 and run psx09 on SIS for `sparc/erc32` with `RTEMS_DEBUG` and `RTEMS_POSIX_API`. | State | psx09 | | --- | --- | | main | fails at the scheduler lookup of processor 1 | | psx09 commit alone | fails with an assertion in `_RBTree_Extract()` | | both commits | passes | **BSP** `sparc/erc32` ยท **Simulator** SIS ## AI Details <!-- Make sure you have read our statement at https://www.rtems.org/generative-ai/ --> ### Prompt used None as a single prompt. The work was done in interactive Claude Code sessions on the RTEMS tree. The task was to fix the defect of #5745 and to split the psx09 part into #5788. Each change was directed and reviewed. ### AI model used Claude Opus 5 (claude-opus-5) and Claude Opus 5.5 (claude-opus-5-5), through Claude Code. ### How AI was used for the contribution - ( ) Formatting - ( ) Test creation. - ( ) Code comments. - ( ) The entire contribution was generated using AI - ( ) AI code completion such as Copilot in VSCode. The implementation, the test change, the commit messages and this description were produced in those sessions under my direction. ### Access I have not used a product which claims copyright in its output, and I have legitimate access to the one I used. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1516 You're receiving this email because of your account on gitlab.rtems.org.
