My totally noob in QEMU guess -
my bet it's CR4.OSFXSR which is controlled by presence of
cpuid.1.edx[24] - FXSR bit (FXSAVE and FXRSTOR) instructions.
That would affect floating point as well.
I'm curious - is there any way in QEMU to redefine returned cpuid leaf
values? It will be interesting to see results if that given bit will
be disabled in configuration.
qemu -cpu host,-flag
I tried that value, result is an error:
Unable to find x86 CPU definition
