[PATCH v3 0/5] SGX NUMA support plus vepc reset

From: Yang Zhong
Subject: [PATCH v3 0/5] SGX NUMA support plus vepc reset
Date: Mon, 1 Nov 2021 12:20:04 -0400

The basic SGX patches were merged into Qemu release, the left NUMA
function for SGX should be enabled. The patch1 implemented the SGX NUMA
ACPI to enable NUMA in the SGX guest. Since Libvirt need detailed host
SGX EPC sections info to decide how to allocate EPC sections for SGX NUMA
guest, the SGXEPCSection list is introduced to show detailed sections info
in the monitor or HMP interface.

This version also plus the vEPC reset support because the related kernel
patches were merged into tip tree master branch, please ref below link:
or the tip tree master branch.



Changes from V2:
- Updated the reset patch(patch 5), reduced to 2 pass.(Paolo)

Changes from V1:

- changed the "index" to "node" in struct SGXEPCSection.(Eric, Paolo)
- squashed the previous patch 4 and patch 5 into patch 3.(Paolo)
- added reset patch(patch 5) into this version.
