NAME         top

       systemd-tpm2-generator - Generator for inserting TPM2
       synchronization point in the boot process

SYNOPSIS         top

       /usr/lib/systemd/system-generators/systemd-tpm2-generator

DESCRIPTION         top

       systemd-tpm2-generator is a generator that adds a Wants=
       dependency from sysinit.target to tpm2.target when it detects that
       the firmware discovered a TPM2 device but the OS kernel so far did
       not.  tpm2.target is supposed to act as synchronization point for
       all services that require TPM2 device access. See
       systemd.special(7) for details.

       The systemd.tpm2_wait= kernel command line option may be used to
       override behaviour of the generator. It accepts a boolean value:
       if true then tpm2.target will be added as synchronization point
       even if the firmware has not detected a TPM2 device. If false, the
       target will not be inserted even if firmware reported a device but
       the OS kernel does not expose a device for it yet. The latter
       might be useful in environments where a suitable TPM2 driver for
       the available hardware is not available.

       systemd-tpm2-generator implements systemd.generator(7).
