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)?

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.
The parameter "-smp 2",didn't work. Does qemu support arch arm -v8 when using the parameter(-smp)?

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.
