[libvirt][PATCH v10 1/5] qemu: provide support to query the SGX capability
Haibin Huang
haibin.huang at intel.com
Sat Jan 29 01:49:57 UTC 2022
QEMU version >= 6.2.0 provides support for creating enclave on
SGX x86 platform using Software Guard Extensions (SGX) feature.
This patch adds support to query the SGX capability from the qemu.
