The Qualcomm Snapdragon 625, identified by the chipset code MSM8953, represents a pivotal moment in mobile architecture history. Released in 2016, it was the first mobile SoC (System on Chip) to be manufactured using a 14nm FinFET process. While now considered a legacy platform, the MSM8953 remains a subject of intense relevance for embedded Linux developers, Android aftermarket developers (custom ROMs), and IoT engineers.

The Cortex-A53 cores in the MSM8953 are efficient but not high-performance. In a high-quality driver, Interrupt Service Routines (ISRs) must be kept as short as possible. Developers should utilize threaded IRQs ( request_threaded_irq ) for heavy processing tasks, such as handling touch screen data or sensor events. This prevents the ARM64 cores from stalling in interrupt context, maintaining UI fluidity.
