Since shaz won’t post on the blog himself, I’ll post it here for him. This comes from his mail to SERG Archive:
This one is specially for Dr.M and Mr.T. The tpm_dev is a kernel module for backward compatibility, when application space made a call to tpm driver i.e. before TIS and 1.2 specification. Do you agree recluze? Now this kernel module is not required when a user space library, “tddl”, can forward userspace requests to “tpmd” the tpm daemon. Do we really need to port tpm_dev module to kernel. It will not be tough but the lesser we handle at a time the better possibility to troubleshoot.
Waiting for ur suggestions. I know its not very difficult to decide but wanted a group decision so that we are even.
I’m not sure what tpm_dev is. I never came across it during our implementation. If as you say, it’s something from before tpm_tis, we probably don’t need it. Tpm1.1 spec had many problems and has been _extensively_ revised in 1.2. So, I don’t think you should worry about it until the troubleshooting phase. Maybe Mr. T and DrM can shed more light.
I had the same opinion about it too. Now that I went through the readme of tpm emulator 0.5v, I came across this info that tpm_dev is totally obsolete now so now have to figure out how much obsolete
It was supported till 0.3v
