Subject: [PATCH v4 0/8] xen: Xen vTPM stubdomains
Precedence: list
Content-Type: text/plain; charset="US-ASCII"

This patchset introduces the basic recipes necessary to build Xen
stubdomains, in particular the vTPM and vTPM Manager stubdomains. vTPM
stubdomains provide Xen guest domains access to a virtualized TPM. The
vTPM Manager stubdomain manages each of the vTPM domains and seals them
to the physical TPM. The intention of this patchset is to provide the
ability to build Xen stubdomains separately from the rest of the Xen
components since the stubdomains have separate dependencies that are
hard-coded within the Xen build and configuration files.  Separating the
stubdomain recipes and dependencies from the rest of the Xen build gives
the ability to use newer or different libraries than what is currently
used.

The stubdom.inc file defines a set of CPPFLAGS, CFLAGS, and LDFLAGS
common for building all Xen stubdomains. Xen stubdomains are
cross-compiled with the MiniOS, which creates some issues when trying to
compile stubdomains in an OpenEmbedded environment. To address these
issues and to ensure the stubdoms are built as Xen had intended, all of
the build flags and build tools that are exported into the environment
by OE have been unset. Each of the new recipes introduced here then
implements the build flags and the tools as though the build had been
run in the bare-metal environment.

Recipes to create slightly modified source packages for lwIP amd Mini-OS
are introduced to standardize the dependency tree among stubdomain
related recipes and to avoid the hassle of maintaining the same tasks
within many recipes.

Xen vTPM stubdomains have depencencies on static libraries for newlib,
polarssl, gmp, and tpm emulator. Xen vTPM Manager stubdomain has
dependencies on static libraries for newlib and polarssl.

The newlib, polarssl, gmp, and tpm emulator recipes are constructed to
behave the same as a bare-metal build. These recipes are cross-compiled
against both the Xen and MiniOS source code.

The xen-vtpm recipe is responsible for building and installing the vTPM
and vTPM Manager stubdomain images into the Xen boot directory. xen-vtpm
would need to be added to DISTRO_FEATURES the similar for what is done
for Xen.

---
Changes in v4:
 - Fix whitespace errors in MiniOS, Newlib, and TPM Emulator patchfiles
 - Corrected type in Newlib recipe
Changes in v3:
 - Limit builds to 64-bit only through COMPATIBLE_HOST
 - Change Xen version comparison logic in xen-vtpm recipe
 - Introduce MiniOS patch for GCC v7 that was not backported into the
   4.9.x releases
 - Change cross-root-${XEN_TARGET_ARCH} to cross-root-${GNU_TARGET_ARCH}
Changes in v2:
 - Multi-line variables formatted to match OE style guide
 - SRC_URI formatted to use SRCREV rather than git tag
 - patches formatted to striplevel=1
 - introduced Mini-OS recipe
 - Removed Xen dependency since this is handled (mostly) by Mini-OS
 - Changed version number of xen-vtpm recipe to match Xen version
