At the moment the only visibility we have is "the CPU supports TME" and "the kernel printed a message in the journal". The sysfs/procfs file read allows us to notify the admin if the firmware is deliberately disabling TME for some reason, without resorting to `grep` on dmesg. I don't think perfect should be the enemy of the good. Richard.
