- user_xfeatures
Track which features are currently enabled for the vCPU
Please rename to alloc_xfeatures
- user_perm
Copied from guest_perm of the group leader thread. The first
vCPU which does the copy locks the guest_perm
Please rename to perm_xfeatures.
- realloc_request
KVM sets this field to request dynamically-enabled features
which require reallocation of @fpstate
This field should be in vcpu->arch, and there is no need for
fpu_guest_realloc_fpstate. Rename __xfd_enable_feature to
fpu_enable_xfd_feature and add it to the public API, then just do
if (unlikely(vcpu->arch.xfd_realloc_request)) {
u64 request = vcpu->arch.xfd_realloc_request;
ret = fpu_enable_xfd(request, enter_guest);
}
to kvm_put_guest_fpu.
