If preserving the current qemu is not necessary, then I can just update devel/qemu to version 4.1.0 and not add devel/qemu4. This probably makes more sense  ...

Agree. On ubuntu, the supporting libraries are not needed at all as they can be installed through the standard package manager. But building them inside RSB makes it easier for the end-user who does not need to figure out what to install (or read the manual .. :-)

Not really, the tests are dead-locked somehow. This is probably because of qemu timing behavior. Here is the list of failures:



It would be great if rtems-test could (optionally) take a timeout value from the bsp file, as some targets need a bit longer delay. (e.g. crypt01.exe fails on sis/RISC-V due to this).
