similar to: [PATCH][vTPM][XM-TEST] echo command string break-up fix

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 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>

The attached patch - fixes a problem in the vTPM backend where the timer was killed when the timer function was run - removes a variable from being put in the ring by the frontend - reformatting due to indent tool running over some of the files Has been tested with the vtpm-relevant parts of xm-test.

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

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

The following test case does local migration 3 times in a loop.

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.

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

This patch adds TCG BIOS extensions to the high memory area along with some often-used libc utility functions. The TCG extensions are described here: https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf I have tried to keep the patching with rombios.c to a minimum, but some amount of code needs to be inserted at various locations. The code is

Hi, i am using Xen 3.2.0 and want to use the TPM in dom0. I have activated vtpm and everything runs fine in my domUs. The question is, how can I access the TPM in dom0? As far as I know vtpm_managerd exclusively locks /dev/tpm0. As soon as I start vtpm_managerd my own program cannot access the TPM anymore. Is there a vtpm instance for dom0 like the ones for the user domains? Thanks in advance

This patch adds an implementation of the TCG BIOS extensions to the Bochs BIOS and enables logging of boot measurements using the previously implemented support for TCPA ACPI tables. A low-level driver for a TPM TIS device and an Atmel device is provided. The implemented specification is described here:

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.

Following the ACPI spec. I improved the way the RSDP is found in the BIOS extension so that it will still be found if it ever moves. Also makes the code look better.
