Yes, that seems to be exactly my problem. So it's not intentionally
disabled. Then I can hope that it may be fixed some day. Thanks for
your help.

The only loaded module with "rng" in its name is "rng_core". That one
is present in both kernels, but four TPM-related modules are absent
from Linux 6.1:

generator disappeared.

number generators available:
# cat /sys/class/misc/hw_random/rng_available
ccp-1-rng tpm-rng-0
ccp-1-rng is nonfunctional because AMD's
