[PATCH] target/i386/hax: Add XCR0 support

[Wang, Wenchao]

Hi, Thomas,

 

As HAXM v7.8.0 is released and it added XCR0 support, it needs this patch to add corresponding support into HAX user space of QEMU. I have pushed this merge request before and Philippe has reviewed it and he thought the change is correct. If no one else raises any other opinion, could you help to merge this patch for HAX? We have verified the patched QEMU and it can launch all guest OSes. Thanks for your support.

 

 

Best Regards,

Wenchao
