Emulation: QEMU 10.0 / bboot 0.8
QEMU is an open-source computer emulator and virtualizer. The emulation of complete computers also makes it possible to run operating systems such as AmigaOS 4 or MorphOS under QEMU that are tailored to a quite specific hardware platform. This support is provided by QEMU developer Zoltan Balaton, who clearly summarises the possibilities on a specially created and now redesigned website.
QEMU is now available in version 10.0.0, Windows installers are provided as usual by Stefan Weil.
Version 0.8 of the bootloader "bboot" for loading AmigaOS 4 on QEMU-emulated AmigaOne and Pegasos2 machines, which was released by Zoltan Balaton about a month ago, requires the options -kernel, -initrd and -append for the amigaone machine, which are now available in QEMU 10.0. This makes it easier to use and is similar to pegasos2. Older bboot versions still require the -device loader options and will not work with -kernel on amigaone. Since the amigaone emulation might have less problems than pegasos2 (and is still available), according to Zoltan Balaton this might be a better choice now.
Finally, the developer has created a new subpage on VFIO device drivers under Linux: VFIO is a device driver that is used to assign virtual machines to devices and thus enable full access to a specific GPU, for example.
As he adds to us, the use of a GPU with VFIO on qemu-system-ppc is currently still experimental and would take some effort to set up. However, some users have managed to achieve usable results: it is therefore possible in principle, even if it is not easy to implement. (dr)
