# EC is configured to power off the system at 105C, so add a two degree
# buffer so the OS can gracefully shutdown.

# EC is configured to assert PROCHOT at 100C. That drastically lowers
# performance. Instead we will tell the OS to start throttling the CPUs
# at 95C in hopes that we don't hit the PROCHOT limit.
#
# We set use_acpi1_thermal_zone_scope because the Chrome ec.asl
# performs a `Notify` to the `_\TZ` scope.
