similar to: [PATCH] Fix for vTPM backend

This patch adds a TPM device model to the qemu dm for fully virtualized VMs. It is enabled in the VM only if the user requests a TPM device in the vm configuration file using the ''vtpm=[...]'' line. It enables the qemu device model command line with a ''vtpm_instance <instance number>'' parameter. Signed-off-by: David Safford <safford@watson.ibm.com>

This patch should be applied the source tree once the 2.6.16-rc4 or 2.6.17 or a later kernel is used. I am sending it now in order not to break the build when switching. I am updating tpm.c and tpm.h to follow the changes in mainline. As a result of the patch, all changes to these two files (when compared to mainline) are surrounded by #ifdef CONFIG_XEN. Since now the chip structure is returned

When redirecting the output of the echo command using ''>'' on bash, the output seems to be broken up into multiple write()s (depending on the version of busybox?). Unfortunately /dev/tpm0 needs to have the complete command written to in one chunk. The work-around ''echo <string> > file ; cat file > /dev/tpm0'' seems to get around this problem. The

Attached is the patch that provides additions to include files, particularly to support the control messages for the TPM front- and backend drivers.

I am removing the experimental feature that allows buffer sizes for transfers from TPMs larger than 2kb. This could become useful if a vTPM is located in its owns domain and needs to be serialized for suspension or migration and the packet size becomes bigger than the current limit. Partial reads were supposed to complement this feature for applications to know how many bytes to read from

This patch adds a TIS device model compliant to the 1.2 TPM specification to Qemu. It implements all registers necessary to make the Linux TIS driver work (tpm_tis.c). All of the basic registers supported by this type of device are implemented. Also the locality selection has been implemented, but has not been tested. The legacy registers as described in the specification are not supported.

I''d like to write some documentation for vtpm as a whole but wanted to ask what your preference is on where it gets located and how its formatted. Right now the old vtpm uses docs/misc/vtpm.txt. I can just update this file or do something else. Here are my current suggestions: READMEs in stubdom/vtpm and stubdom/vtpmmgr explaining their command line arguments and specifics.

The following are a set of patches to run the berlios tpm emulator 0.6.1 in a mini-os domain, called vtpm-stubdom. Documentation on how to use this domain is located at stubdom/vtpm/README. The following are a series of patches that enable this domain and also add significant stability improvements to the entire vTPM subsystem, including the original method of using vtpmd as a process.

The following test case does local migration 3 times in a loop. I currently see the following error output on x86-64 (only!) inside the guest (change debugMe in line 68 of xm-test/lib/XmTestLib/Console.py to True): @%@%> XENBUS error -12 while reading message XENBUS error -12 while reading message XENBUS unexpected type [1325400064], expected [4] XENBUS error -12 while reading message XENBUS

Hello everyone, I am sorry for interrupting your work I am following the correspondence in silence. I am trying to build a vtpm implementation into xen 6.2 but I was not able to find all the means to do it. What can be found is just abstract knowledge. Most of the info always forwards me to this doc

This patch rewrites the rtc/timeoffset entry so the VM''s record can be retrieved with the Java xmlrpc library. If the entry is ''None'' it upsets the xmlrpc parser. This fixes it, though maybe there''s a better place in xend to place similar code. Signed-off-by: Stefan Berger <stefanb@us.ibm.com> _______________________________________________ Xen-devel
