Hi guys,
If I understand the Linux boot correctly, GRUB 2 will drop Linux in a 32-bit
protected mode,
using the Linux 32-bit boot protocol.
Since Linux has a 64-bit boot protocol, I'm thinking that we can make use of
that. On x86_64
target, if we can make use of 64-bit boot protocol, we'll drop Linux in long
mode directly, thus
less code executed in the GRUB side, and less code in Linux side.
Obviously it's cleaner to just use 32-bit protocol to boot both i386 and x86_64
kernel, but this
will not add much complexity.
Just new to this mailing list, am I missing anything?
