RH-MergeRequest: 65: Enable SGX and add SGX Numa support
|
|
RH-Commit: [5/5] 0d3b9f37cd3cce202050ba3bd51eef4410ef3d38
|
|
RH-Bugzilla: 2033708

|
|
|
|
The SGX NUMA patches were merged into Qemu 7.0 release, we need
|
|
clarify detailed version history information and also change
|
|
some related comments, which make SGX related comments clearer.
|
|
|
|
The QMP command schema promises backwards compatibility as standard.
|
|
We temporarily restore "@section-size", which can avoid incompatible
|
|
API breakage. The "@section-size" will be deprecated in 7.2 version.
