Christian Borntraeger b9e5dc8d45 KVM: provide synchronous registers in kvm_run ... On some cpus the overhead for virtualization instructions is in the same range as a system call. Having to call multiple ioctls to get set registers will make certain userspace handled exits more expensive than necessary. Lets provide a section in kvm_run that works as a shared save area for guest registers. We also provide two 64bit flags fields (architecture specific), that will specify 1. which parts of these fields are valid. 2. which registers were modified by userspace Each bit for these flag fields will define a group of registers (like general purpose) or a single register.
