Even when using open-source drivers, you will need the proprietary firmware blobs (located in /lib/firmware/qcom/ ) for the DSP (Hexagon), GPU, and modem to function properly. 5.

Avoid the mainline ath10k_sdio – it lacks proper runtime PM for this chip.
Ensure the ASoC (ALSA System on Chip) drivers for msm8953 are loaded to support low-latency audio processing. 4.

The MSM8953 is not dead; it is a mature workhorse. With high-quality ARM64 drivers, it will continue to power reliable, efficient devices for years to come. Invest the time to find or build them correctly—your device’s performance depends on it.
A production-grade driver must cleanly parse properties from the Device Tree. Below is an abstract example of how a high-quality MSM8953 peripheral driver initializes hardware resources using the modern platform_driver API: Reliability in Modern Apps : It handles the
Optimizing the MSM8953 (Snapdragon 625) platform for modern arm64 environments requires a deep understanding of its architecture and driver ecosystem. While this SoC is a veteran of the mobile world, its efficiency and octa-core Cortex-A53 design continue to make it a popular choice for IoT, embedded systems, and custom Android ROM development. Achieving high-quality driver performance on arm64 requires a strategic approach to kernel integration and hardware abstraction.
With eight cores executing code simultaneously, race conditions are a significant risk. High-quality drivers protect shared state variables using appropriate synchronization primitives:
CONFIG_INTERCONNECT=y CONFIG_INTERCONNECT_QCOM=y CONFIG_INTERCONNECT_QCOM_MSM8953=y
