Thanks! I should be able to post a Tested-by next Monday. Boris, are you going to pick it up for 4.21?

And as far as qemu/qboot changes, should we assume that the general approach is acceptable? I understand that the patches will probably need to go through some iterations but I want to make sure we have a path forward there. -boris ___ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

It's not really code, only Kconfig (and I remarked on it just now), but it doesn't hurt of course. > And as far as qemu/qboot changes, should we assume that the general > approach is acceptable?

I have already reviewed the qboot parts, I guess we will also want an option ROM similar to linuxboot/multiboot for SeaBIOS support but that's simple matter of programming. :) Paolo ___ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
