      qemu-ga: Add Windows VSS provider and requester as DLL · b39297ae
      Tomoki Sekiyama authored
      
      
      Adds VSS provider and requester as a qga-vss.dll, which is loaded by
      Windows VSS service as well as by qemu-ga.
      
      "provider.cpp" implements a basic stub of a software VSS provider.
      Currently, this module only relays a frozen event from VSS service to the
      agent, and thaw event from the agent to VSS service, to block VSS process
      to keep the system frozen while snapshots are taken at the host.
      
      To register the provider to the guest system as COM+ application, the type
      library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl),
      VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also
      adds pre-compiled .tlb file in the repository in order to enable
      cross-compile qemu-ga.exe for Windows with VSS support.
      
      "requester.cpp" provides the VSS requester to kick the VSS snapshot process.
      Qemu-ga.exe works without the DLL, although fsfreeze features are disabled.
      
      These functions are only supported in Windows 2003 or later. In older
      systems, fsfreeze features are disabled.
      
      In several versions of Windows which don't support attribute
      VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error
      VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error.
      To solve this fundamentally, we need a framework to handle mount writable
      snapshot on guests, which is required by VSS auto-recovery feature
      (cleanup phase after a snapshot is taken).

      target-i386: Add "feature-words" property to X86CPU · 8e8aba50
      Eduardo Habkost authored
      
      
      This property will be useful for libvirt, as libvirt already has logic
      based on low-level feature bits (not feature names), so it will be
      really easy to convert the current libvirt logic to something using the
      "feature-words" property.
      
      The property will have two main use cases:
       - Checking host capabilities, by checking the features of the "host"
         CPU model
       - Checking which features are enabled on each CPU model
      
      Example output:
      
        $ ./QMP/qmp --path=/tmp/m \
          qom-get --path=/machine/icc-bridge/icc/child[0] \
                  --property=feature-words

      tpm: reorganize headers and split hardware part · bdee56f5
      Paolo Bonzini authored
      
      
      The TPM subsystem does not have a full front-end/back-end separation.
      The sole available backend, tpm_passthrough, depends on the data
      structures of the sole available frontend, tpm_tis.
      
      However, we can at least try to split the user interface (tpm.c) from the
      implementation (hw/tpm).  The patches makes tpm.c not include tpm_int.h,
      which is shared between tpm_tis.c and tpm_passthrough.c; instead it
      moves more stuff to tpm_backend.h.

      configure: Don't fall back to gthread coroutine backend · 7c2acc70
      Peter Maydell authored
      
      
      The gthread coroutine backend is broken and does not produce a working
      QEMU; it is only useful for some very limited debugging situations.
      Clean up the backend selection logic in configure so that it now runs
      "if on windows use windows; else prefer ucontext; else sigaltstack".
      
      To do this we refactor the configure code to separate out "test
      whether we have a working ucontext", "pick a default if user didn't
      specify" and "validate that user didn't specify something invalid",
      rather than having all three of these run together. We also simplify
      the Makefile logic so it just links in the backend the configure
      script selects.

      Support for TPM command line options · d1a0cf73
      Stefan Berger authored
      
      
      This patch adds support for TPM command line options.
      The command line options supported here are
      
      ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
                 -device tpm-tis,tpmdev=<id>,id=<other id>
      
      and
      
      ./qemu-... -tpmdev help
      
      where the latter works similar to -soundhw help and shows a list of
      available TPM backends (for example 'passthrough').
      
      Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
      passthrough driver. The interpretation of the other parameters along
      with determining whether enough parameters were provided is pushed into
      the backend driver, which needs to implement the interface function
      'create' and return a TPMDriverOpts structure if the VM can be started or
      'NULL' if not enough or bad parameters were provided.
      
      Monitor support for 'info tpm' has been added. It for example prints the
      following:
      
      (qemu) info tpm
      TPM devices:
       tpm0: model=tpm-tis
        \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel
