Hi,
The tpm module included in grub 2.04 doesn't seem to be installed/loaded by
default. How can I configure it such that it can be built and included
into the core.img?
Or is the tpm module ready for general use yet?
Regards,
Hanson

Figured it out:
$ ./configure --with-platform=efi --target=x86_64 --prefix=/usr
$ make
$ sudo make install
$ sudo grub-install --modules=tpm
Reboot, then
$ tpm2_pcrread sha256
sha256:
