Arm and Qualcomm have been in a war for quite a while now over Qualcomm's Oryon cores. These cores are used in the Snapdragon X series and, now, the Snapdragon 8 Elite. To give a brief overview of the situation,

Arm has finally thrown its toys and given 60 days notice that it intends to cancel Qualcomm's licence to produce chips based on Arm technology. So says Bloomberg, which claims to have seen Arm documents detailing the move.

Any company that makes Arm chips must license technology from Arm Holdings plc, the British company that develops the instruction set. Companies can license the instruction set and create their own CPU designs or license one of Arm's ready-made Cortex CPU core designs to incorporate into their own chips.
