I got an issue, when testing command like this :qemu–system–aarch64 -kernel uimage -smp 2...
The whole command , qemu–system–aarch64 -kernel uimage -M vexpress -a15 -cpu cortex-a57 -smp 2 -m256 --nographic The issue is that when running into shell, i didn't find two cpus. The parameter "-smp 2",didn't work. Does qemu support arch arm -v8 when using the parameter(-smp)? From jqh mobile phone.

In order to debug your problem further it would be nice if you could provide a little more information about your setup. Which version of Fiasco are you using (snapshot or public development version)? Is CONFIG_MP in your Fiasco configuration enabled? Please also attach the report generated by "make report" from your L4Re build directory. Regards, Matthias.

Currently, the code to boot up secondary cores on the QEMU rv/vexpress platform is missing in Fiasco for arm64, i.e. your observation is right, that only a single core comes up. This is being worked on. Adam
