Hi, Philippe,
As Paolo did not comment with this patch, as you used to think it looks
correct, could you help to merge this one-line patch as no one picked it up so
far? Thanks a lot.
Best Regards,
Wenchao

Hi, Philippe,
Do you agree with my opinion and is there any further process that I need to
follow to get this patch merged? Thanks a lot.
I don't understand this part of HAXM enough, but per your explanation, your
change looks correct. I'll let Paolo decide :)
Regards,
Phil.

Hi, Philippe,
It is just the full patch. Currently, the implementation of HAXM is simple, we
did not synchronize the vCPU register for xcr0 from QEMU. HAXM will handle the
xcr0 state within the kernel space, including initialization, update, etc. This
patch adds the xcr0 variable for allocating extra 8-byte buffer occupation,
which will be passed between QEMU and HAXM when hax_sync_vcpu_state() is
invoked. We have verified the patched QEMU and it can launch all guest OSes.
Thanks for your comments.
Best Regards,
Wenchao
