It's already used for the Xen guest kernel, just not GCC. The gcc manpage says that all -march=pentium4 means is enable MMX, SSE, and SSE2, which I believe the old Atoms support, but even if they don't, running any VM on such low-spec processors isn't likely to work anyway. Using -march=i686 is an alias for Pentium Pro, that is, before the Pentium II. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

I would rather prefer -march=i686 and -mtune=generic for the x86 virtual machine images, but I am not an x86 expert. Do I need hardware support for visualization in my host CPU for all these images?
