The Nitro Enclaves driver keeps an internal info per each enclave.
This is needed to be able to manage enclave resources state, enclave
notifications and have a reference of the PCI device that handles
command requests for enclave lifetime management.
Changelog
v9 -> v10
* Update commit message to include the changelog before the SoB tag(s).
v8 -> v9
* Add data structure to keep references to both Nitro Enclaves misc and
PCI devices.
v7 -> v8
* No changes.
v6 -> v7
* Update the naming and add more comments to make more clear the logic
of handling full CPU cores and dedicating them to the enclave.
v5 -> v6
* Update documentation to kernel-doc format.
* Include in the enclave memory region data structure the user space
address and size for duplicate user space memory regions checks.
v4 -> v5
* Include enclave cores field in the enclave metadata.
* Update the vCPU ids data structure to be a cpumask instead of a list.
v3 -> v4
* Add NUMA node field for an enclave metadata as the enclave memory and
CPUs need to be from the same NUMA node.
v2 -> v3
* Remove the GPL additional wording as SPDX-License-Identifier is
already in place.
v1 -> v2
* Add enclave memory regions and vcpus count for enclave bookkeeping.
* Update ne_state comments to reflect NE_START_ENCLAVE ioctl naming
update.
