I don't confirm this.  I have Linux version 5.12.0-rc5+ installed and I
see the attached in my binary_bios_measurements (I've run it through
tpm2-eventlog so you can see the actual events).

What that commit did was to allow the event log to be provided by the
ACPI table if one existed rather than always defaulting to it being
provided by the EFI configuration table.  What I suspect has happened
from this:

Is that somehow you've got an empty TPM2 table installed in ACPI but I
don't know how you've done this.  On my OVMF boot I'm using the direct
kernel command line and I have secure boot enabled but not activated,
which is why you only see PCRs 0-7 in the log.
