Zusammenfassung:Various embodiments of methods and systems for thermally aware booting in a portable computing device (PCD) are disclosed. Because bringing high power consumption processing components online when a PCD is booted under less than ideal thermal conditions can be detrimental to the health of the PCD, embodiments leverage a low power processing component early in a boot sequence to authorize, delay or modify the boot sequence based on measured thermal indicators. One exemplary method is essentially a go/no go method that delays or authorizes completion of a boot sequence based on the thermal indicator measurements. Another exemplary method modifies a boot sequence of a PCD based on a thermal boot policy associated with a thermal boot state. A thermal boot policy may include allowing the boot sequence to complete by modifying the power frequency to which one or more high power consumption components will be booted.
