Chapter 5.2 - shared data

[eckhard-delfs-qualcomm]

Second bullet: "non-confidential memory - used only for shared data"...
Should there be a way to exclusively share memory between TVMs managed by different TSMs? I.e. via the sharing option supported by SmMTT. The model described in CoVE seems to limit sharing using non-confidential regions (like the ARM approach via Non-secure). Or is the idea that shared pages are always tagged as non-confidential, even if they are shared privately with another TSM/TVMs, but not with the host OS/VMM?
This feature may also be pushed to a second release.
