[Xen-devel] [PATCH v2] txt: 0/5 - Overview

["Cihula, Joseph" <joseph.cihula@xxxxxxxxx>]

This patch series are changes to Xen to support new functionality, and a 
changed API, in the tboot project (see http://sourceforge.net/projects/tboot 
for more info about tboot).  Some of these changes originated from comments 
received when the first set of Linux tboot/Intel(r) TXT patches were posted to 
LKML.

Attached to this patch is a single patch to be applied to the current tip of 
the tboot source tree (located at http://www.bughost.org/repos.hg/tboot.hg).  
Due to the API change, for those who wish to test the patches, it would be best 
to apply all of the tboot patch at once and test with all of the Xen patches 
applied to Xen.

Since the API changes are not backwards compatible, the resulting tboot will 
not work with a Xen that does not have the patches applied.  Likewise, a Xen 
with these patches applied will not work with the un-patched tboot.  To keep 
backward compatibility would have left the interface and code fairly ugly and 
didn't seem worth the trouble.

The Xen patches are as follows:

xen-txt-01-unified_shutdown_entry.patch    - single tboot entry point for 
shutdown
xen-txt-02c-acpi_gas_support.patch         - ACPI Generic Address Structure for 
tboot shutdown
xen-txt-03c-protect_txt_ranges.patch       - explicitly protect TXT addr ranges 
from dom0
xen-txt-04c-hypervisor_s3_integrity.patch  - hypervisor integrity on S3
xen-txt-05b-use_protected_dmar.patch       - use TXT's DMA-protected DMAR table 
to setup VT-d

We are currently working on a patch that will extend the S3 integrity to 
domains, as configurable via a domain's config file (and always for dom0).

The patches apply cleanly to the latest xen-unstable (c/s 19104:31983c30c460).
