This patch series provides support for enabling Intel's Software
Guard Extensions (SGX) feature in guest VM.
Giving the SGX support in QEMU had been merged. Intel SGX is a
set of instructions that increases the security of application code
and data, giving them more protection from disclosure or modification.
Developers can partition sensitive information into enclaves, which
are areas of execution in memory with more security protection.
The typical flow looks below at very high level:
1. Calls virConnectGetDomainCapabilities API to domain capabilities
that includes the following SGX information.
<feature>
...
<sgx supported='yes'>
<epc_size unit='KiB'>N</epc_size>
</sgx>
...
</feature>
2. User requests to start a guest calling virCreateXML() with SGX
requirement. It does not support NUMA yet, since latest QEMU 6.2
release does not support NUMA.
It should contain
<devices>
...
<memory model='sgx-epc'>
<target>
<size unit='KiB'>N</size>
</target>
</memory>
...
</devices>
Please note that SGX NUMA support will be implemented in future patches.
Haibin Huang (4):
Get SGX capabilities form QMP
Convert QMP capabilities to domain capabilities
Adding of the QEMU CAPS flag for unit test
conf: expose SGX feature in domain capabilities
Lin Yang (2):
conf: Introduce SGX EPC element into device memory xml
qemu: Add command-line to generate SGX EPC memory backend
