While in transit to ZZZ [Airport]; with 2 passengers on board and just prior to entering ZZZ1 Center Control airspace; I started getting occasional low pressurization indications that eventually stopped. After and while in ZZZ Center airspace and talking to ZZZ Center Control I was directed to descend from flight level 310 to 270. After setting up my descent I received a low cabin pressure warning indication that prompted me to don my mask and drop the cabin masks as well. My TBM 850 aircraft is equipped with an emergency descent feature in the event of low pressure and that system went into effect turning me 90 degrees to the right and descending me. While descending I requested priority handling and was diverted to ZZZ1 [Airport] where I landed safely.
TBM 850 pilot reported a low cabin pressure warning indication issue during cruise resulting in a diversion.
