Project:Branches: sebhub/rtems:up/mips to rtems/rtos/rtems:main Author: Sebastian Huber ## Summary Issue #5742: Six defects of the BSP and the MIPS port Issue #5752: The exception vector publishes the frame in a global Issue #5754: The frame indices and the exception resume Issue #5764: The floating point unit has a context of its own Issue #5765: The exception return ignores a changed program counter Issue #5766: The boot command line pointer holds a loop counter Issue #5767: The polled character input blocks Issue #5768: The interrupt return drops the status register Issue #5769: The exception frame holds $f31 as fcr31 The branch carries the MIPS work of ten issues. It repairs the Malta BSP so that it runs the test suite, gives the port its own exception handler registration, brings the floating point context in line with the arm, powerpc and riscv ports, and adds the exception resume. The validation tests of the context switch, the interrupt processing and the exception resume come from specification items. Only the generated sources reach this repository. The tenth issue is #2279, which this section does not list, because the tracker already carried it. The libdl tests of the `hurricane`, `rbtx4925` and `rbtx4938` BSPs build again. Closes #5742. Closes #5752. Closes #5754. Closes #5764. Closes #5765. Closes #5766. Closes #5767. Closes #5768. Closes #5769. Closes #2279. **BSP** `mips/malta` and `mips/jmr3904` ยท **Simulator** Qemu and the GDB simulator ## 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 an interactive Claude Code session on the RTEMS tree. The task was to run the test suites of the simulator BSPs, diagnose every failure and fix the cause. Each change was directed and reviewed. ### AI model used Claude Opus 5 (claude-opus-5), through Claude Code. ### How AI was used for the contribution - [ ] Formatting - [ ] Test creation. - [x] Code comments. - [ ] The entire contribution was generated using AI - [ ] AI code completion such as Copilot in VSCode. The diagnosis and the implementation were produced in that session under my direction, and the commit messages were drafted there. ### 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/1486 You're receiving this email because of your account on gitlab.rtems.org.
