T-state is Processor Clock Throttling state. It is designated to throttle the
processor clock in a few specific situations, like the CPU temperature
exceeds a threshold value.

T-state is defined in ACPI spec and need BIOS implementation to get
supported. The warning message means T-state is not supported on
your machine. This is mostly because the BIOS doesn't support it.

Don't worry, your system won't be impacted at all without T-state support.
BIOS and Solaris kernel will cover all the cases of T-state.
