[Xen-users] "modprobe tpmbk" and "CONFIG_XEN_TPMDEV_BACKEND"

[ilish ilish <ilishim@xxxxxxxxxxx>]

Hi ,

I have installed Xen4.0.0 and kernel 2.6.13 on my debian system and I boot from this configuration. Now I want to use vtpm_managerd command. First I used "modprobe tpmbk" and got an error like "FATAL: Module tpmbk not found." 

Every source I read tells me that I have to modularise CONFIG_XEN_TPMDEV_BACKEND entry in my kernel configuration. I typed "make menuconfig" on my kernel's directory and searched for "Backend" and saw that there are a lot of entries for xen and backend and I did not see anything specifically TPMDEV_BACKEND.

These are the entries related to Xen backend. Can someone tell me which one to modularize to make tpmbk work?
