Software Guard eXtensions (SGX) hardware enables for user space
applications to set aside private memory regions of code and data.
These memory regions are called enclaves.
The support can be determined by
grep sgx /proc/cpuinfo
SGX must both be supported in the processor and enabled by the BIOS.
This commit labels 3 device nodes with a new label for each device type.
/dev/sgx_enclave can be used by any application (not only virt-related)
to create and interact with an SGX enclave through SGX kernel driver.
Each enclave is contained in an Enclave Page Cache (EPC).
/dev/sgx_vepc can be used by a hypervisor (e.g. qemu) to create an EPC
(without creating an enclave in it) that can be passed to a guest, so
the applications running in the guest system can create SGX enclaves.
/dev/sgx_provision is used to set PROVISION_KEY flag on the enclave
by calling an ioctl() on the enclave with fd to /dev/sgx_provision
as another argument. QEMU does open this file, perhaps also some other
processes can.
