Hold off on these patches--there appear to be a few issues when I run them on
the current tip.

> Subject: [Xense-devel] [PATCH] txt: 0/6 - Overview
>
> 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-xen_phys_addr_start_fix.patch - "fix" xen_phys_start
for 32b builds
> xen-txt-02-protect_txt_ranges.patch - explicitly protect TXT addr
ranges from dom0
> xen-txt-03-use_protected_dmar.patch - use TXT''s
DMA-protected DMAR table to setup VT-d
> xen-txt-04-acpi_gas_support.patch - ACPI Generic Address Structure
for tboot shutdown
> xen-txt-05-unified_shutdown_entry.patch - single tboot entry point for
shutdown
> xen-txt-06-hypervisor_s3_integrity.patch - hypervisor integrity on S3
>
> 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.
