hi gents

would anybody know why tpm_rng is gone from 3.10.0-957.el7.x86_64 ?

I need it on my oldish heavy boxes, so do lots of others I would imagine.

According to `yum provides '*/tpm_rng*'` it has never been shipped by CentOS. What does `rpm -qf /path/to/your/tpm_rng.ko.xz` say about what package provides it?

Ah, it's called tpm-rng.ko.xz (not tpm_rng) and was part of the 3.10.0-862* kernels and is indeed gone from the -957 one.

I'm guessing it's related to https://bugzilla.redhat.com/show_bug.cgi?id=1627822

it actually seems to work, and seems that something is in that new kernel that now, without that module, makes tpm/hwrg works on my old Opterons, 63xxx.

thanks, L.
