       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 doesn't 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).
