Project:Branches: sebhub/rtems-sis:up/gr740-irqmap to rtems/tools/rtems-sis:main Author: Sebastian Huber ## Summary The RTEMS GR740 BSP translates every interrupt through the interrupt map registers of the IRQ(A)MP at offset 0x300. SIS decoded the IRQ(A)MP offset with `addr & 0xff` and had no map registers. The BSP thus built its map from zero or from other registers, and no clock tick reached it. | Commit | Change | | --- | --- | | build: Replace autotools with waf | waf 2.1.9 replaces the generated autotools files and `build-aux/`. The readline check also tests the header. | | tap: Rewrite the TUN device setup | removes a copy of the example of the Linux TUN/TAP document, which is GPL-2.0 only | | Adopt the REUSE licensing conventions | adds SPDX tags, `LICENSES/` and `REUSE.toml`. `reuse lint` passes. | | gr740: Map the full IRQMP register block | decodes the full 4 KiB block of the IRQ(A)MP | | grlib: Emulate the IRQ(A)MP interrupt map | adds the eight map registers of GR740-UM-DS section 21.3.19, enabled for the GR740 only | The REUSE commit names the origin of each imported file and of each file which received a new header. `sparc.c` and `sparc.h` come from binutils-gdb `sim/erc32/exec.c`. `br_add_interface()` in `tap.c` comes from bridge-utils v1.6. Files without a comment header receive GPL-3.0-or-later, the license of the project. Their holders come from `git blame`. ## Test - Each commit builds with `./waf`. `reuse lint` passes from the REUSE commit on. - The five GR740 reference binaries produce byte identical output under the autotools build and the waf build. - The RTEMS test suite of the GR740 BSP, RTEMS `e9d427c097d`, uni and SMP, passes on SIS with this series. The one exception is `ts-validation-intr.exe`. It fails because the BSP accepts vectors up to 63, and the GR740 has only 32 bus interrupt lines. This is a defect of the BSP, not of SIS. **BSP** sparc/gr740 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 SIS tree. The tasks were to find why the GR740 BSP received no clock tick on SIS, to replace the autotools build, and to make the licensing of every file machine readable. Each change was directed and reviewed. ### AI model used Claude Opus 5.5 (claude-opus-5-5), 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, the implementation and the licensing research were produced in those sessions 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/tools/rtems-sis/-/merge_requests/13 You're receiving this email because of your account on gitlab.rtems.org.
