Since we already have a TYPE_VIRT_MACHINE for other targets, I wonder whether it might be better to use LOONGARCH_VIRT_MACHINE than just VIRT_MACHINE here? Philippe, could you comment on this? Thomas

It is great if there is one QEMU binary which supports different targets. And LOONGARCH_VIRT_MACHINE is ok for me. Regards Bibo Mao > > Thomas

Hi Thomas, Philippe, Does machine name "virt" need be changed if LOONGARCH_VIRT_MACHINE is used? There will be compatible issues if "virt" machine type is not suggested to use. However CPU type "max" is not widely used now, can we get different architectures from CPU type rather than machine type for one QEMU binary which supports different targets?

I assume it should be fine to keep the "virt" machine name and "max" CPU type for each target, we've got a bunch of those already. I assume we'll keep the binary names as symlinks to the generic binary around and then decide via argv[0] about the main target...? Philippe, do you have already concrete plans for this? Thomas

The method using symlinks to generic binary is great. It is transparent to detailed architectures. I will refresh the patch and use LOONGARCH_VIRT_MACHINE macro. Regards Bibo Mao > > Thomas > >
