similar to: [PATCH] Remove variable buffer size and partial reads from tpm.c

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>

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

Hi All, Please read the following steps involved in installing and configuring my Xen box with V-TPM enabled, which I am not able to make it work. Host Linux Distro - CentOS 4.1 Guest Linux distros - Centos 4.1, SUSE TPM module - TPM emulator Downloads: gmp-4.1.4 xen-instable-src.tgz (downloaded on 29/9/2005) bridge-utils-1.0.6.tar.gz compiled and installed gmp-4.1.4 and bridge-utils. Now

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.

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

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

The attached patch allows adjustment of the size of TPM transfer buffers to the size that a lower-layer driver supports.

Hi, In advance, sorry, I am not sure if it''s the right mailing list to ask that, but as my question is half-way between Xen and trousers, I thought asking in both mailing lists would not be too much.... I am currently having a little problem finding out how to make work my seal/unseal things... Running a Debian Lenny on top of Xen 3.5 unstable. with vtpm management enabled on my

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.

Hi again! Succeeded in creating vtpmmgr-stubdom.gz from the source RPM with some shortcuts. ow the next problem seems to be that the libvirt we have will not support the XEN vtpm:s For example: virsh dumpxml <vm-machine> will not contain any info on the vtpm :-( Am I really the first one around with a need for TPM support in the VM:s ??

I can get vtpm_manager to run if I delete /var/vtpm/VTPM. However, when I kill it with control-c, and try to run it again, I get: INFO[VTPM]: Starting VTPM.

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