[Qemu-devel] [RFC PATCH 11/20] linux-headers: Add temporary placeholder for KVM_CAP_SGX_ATTRIBUTE
Posted by Sean Christopherson 6 years, 1 month ago
KVM_CAP_SGX_ATTRIBUTE is a proposed capability for Intel SGX that can be
used by userspace to enable privileged attributes, e.g. access to the
PROVISIONKEY.  The capability number is a placeholder defined well above
existing capabilities so that it's stable during development.
