The new baked image is a Prekernel and a Kernel baked together now, so
essentially we no longer need to pass the Prekernel as -kernel and the
actual kernel image as -initrd to QEMU, leaving the option to pass an
actual initrd or initramfs module later on with multiboot.
Still try parsing the now gone "-audio-help" output first, then attempt
the new "-audiodev help" if stdout was empty. This fixes support for
QEMU 8.2+ audio since "-audio-help" is now an invalid option.
A Python script is much easier to maintain than the organically grown
variable mess that was run.sh.
For now, the script inherits most environment variable modifiability
from the shell script, but this is not a requirement.
While porting this script, a couple of improvements have been made:
- Spaces (especially in paths) cannot break most arguments anymore.
Exceptions are environment variables specifying multiple arguments on
purpose, these should be replaced in the future anyways.
- Force control over virtualization is now possible with
SERENITY_VIRTUALIZATION_SUPPORT. If set to 0, this variable was
sometimes ignored before.
- Handling Windows native QEMU is much more robust. Multiple incorrect
checks for WSL, but not Windows native QEMU, were used before. This
would also allow disabling native Windows QEMU much more easily in the
future, which is necessary for GDB.
- Various machine types had wrong or outdated arguments, such as qn.
