Hi all, We would like to submit our current work on the arm64 port of ipipe/xenomai. We hope that this contribution will encourage further development of arm64 support in ipipe/xenomai.
This port was largely developed on ipipe-3.10 as a base, so it is likely to be the most well tested there. Though recently, we have also ported these changes to ipipe-3.14.44. ( We noticed that 3.10 is missing from rc7. Is this intended, or will 3.10 support return? ) At the end of this message are the relevant git repos and branches for the arm64 port. Also included is a build script to build a minimal busybox linux system which may be ran using qemu (arm64 virt). Development status: The 3.14 port is missing the fast-syscall changes (in entry.S) from armv7, and instead contains the 3.10 entry.S changes forward ported to 3.14. FPU support is incomplete. Smokey tests: 3.10/rc6 smokey tests all pass 3.14/rc6 smokey tests all pass 3.14/rc7 smokey tests sched-quota and sched-tp fail git repos: https://gitlab.mperpetuo.com/it/xenomai-3.git https://gitlab.mperpetuo.com/it/ipipe.git https://gitlab.mperpetuo.com/it/build-scripts.git ipipe/xenomai arm64 branches: ipipe-core-3.10.32-arm-10-arm64-2c, v3.0-rc6-arm64-1c ipipe-core-3.14.44-arm-11-arm64-2, v3.0-rc6-arm64-1c ipipe-core-3.14.44-arm-12-arm64-2, v3.0-rc7-arm64-1c The system is built with the following commands. git clone https://gitlab.mperpetuo.com/it/build-scripts.git mkdir -p build cd build ../build-scripts/build_linux_emulator-arm64.sh or ../build-scripts/build_linux_emulator-arm64.sh --314-rc6 or ../build-scripts/build_linux_emulator-arm64.sh --314-rc7 To run the resulting build: sudo apt-get install qemu-system-arm ( cd out/target/product/xenomai_arm64; ./run.sh ) We look forward to any feedback or questions. Please let us know how we may continue to contribute to move this arm64 port forward. -Don Mahurin _______________________________________________ Xenomai mailing list [email protected] http://xenomai.org/mailman/listinfo/xenomai
