[feature request] linux-image-4.3.0-1-sparc64-smp: tpm random module for linux LDOMs

[Anatoly Pugachev <matorola@gmail.com>]

Package: src:linux
Version: 4.3.3-2
Severity: wishlist

Dear Maintainer,

Can you please enable CONFIG_TCG_TPM (TPM security chip) and
CONFIG_HW_RANDOM_TPM linux kernel config options (as modules), to
enable hardware RNG device for use in LDOM (containers) of debian
sparc64.

Right now, there's no hardware RNG provider is available :

$ ls /sys/class/misc/hw_random
ls: cannot access /sys/class/misc/hw_random: No such file or directory
# grep -i TPM /boot/config-4.3.0-1-sparc64-smp
# CONFIG_TCG_TPM is not set


But if we enable TPM random module (tpm-rng), it will be (output taken
from oracle linux for sparc):

[root@linuxsparc log]# cat /sys/class/misc/hw_random/rng_available
tpm-rng
[root@linuxsparc log]# cat /sys/class/misc/hw_random/rng_current
tpm-rng

[root@linuxsparc log]# grep TPM /boot/config-4.1.8-15.1.el6uek.sparc64
CONFIG_HW_RANDOM_TPM=y
CONFIG_TCG_TPM=y

Thanks.
