I want to emulate mmx/sse for hvm guests when applications inside hvm
guests are compiled for mmx/sse but the underlying hardware doesn't
support mmx/sse. What is the best place to do this? i'm looking at
x86_emulate but i dunno if that is the best place to put the emulation
layer. any suggestions?? also, currently movq emulation is present in
x86_emulate for handling mmio. however, i realized that get_fpu fails
if the hardware doesn't have mmx capability. is it true or am i
missing something here?
