[Xen-devel] [PATCH 0/12] VTPM mini-os

[Matthew Fioravante <matthew.fioravante@xxxxxxxxxx>]

The following set of patches add vtpm-stubdom, a vtpm mini-os domain. 
They also add vtpmmgrdom, a mini-os domain for the vtpm manager.
Also included are number of bug fixes to the original vtpm system, some 
mini-os enhancements, and a few new pieces of software ported to the 
stubdom build structure.
Xen vtpms are now robust and stable and there are many ways to use them:
vtpmd (dom0 process) and vtpm_manager (dom0 process)
vtpm-stubdom (domain) and vtpm_manager (dom0 process)
vtpm-stubdom (domain) and vtpmmgrdom (domain)

Domains communicate using the paravirtualized tpmfront and tpmback 
drivers. Ports of these drivers from linux have been written for 
mini-os. Also included is a tpm hardware driver for mini-os for the vtpm 
manager domain to talk directly to the hardware tpm and bypass dom0.

These patches do not require the previous set of vtpm patches I 
submitted back in august that were not included into xen. In those 
previous patches I had a rudimentary method of disabling certain 
features  in mini-os so vtpms would not have unnecessary drivers like 
network and pci. Since there was debate on the implementation this has 
not been included.
