A Deep Dive into the MSM8953 (Snapdragon 625/626) and Its ARM64 Driver Ecosystem
Introduction: The Unsung Hero of Mid-Range Android
The MSM8953 (Mobile Station Modem 8953), commercially known as the Qualcomm Snapdragon 625, and its slightly faster sibling, the Snapdragon 626, is one of the most prolific mobile system-on-chips (SoCs) ever produced. Released in 2016, it has powered hundreds of devices—from the Xiaomi Redmi Note 4 and Moto Z Play to the Samsung Galaxy A series and countless IoT devices.
EOL for 32-bit user space: Google’s Play Store already requires 64-bit native code. Any remaining 32-bit driver shims will eventually break. msm8953 for arm64 driver
However, "drivers for MSM8953 on ARM64" is a broad topic. This article breaks down exactly what drivers you need, where to find them, and how they interact with ARM64 Linux kernels. A Deep Dive into the MSM8953 (Snapdragon 625/626)
2.6 Sensors (I2C/SPI/IIO)
Drivers for accelerometer, gyro, proximity (e.g., BMI160, LSM6DS3) are in-kernel and architecture-independent. Vendor libraries (e
- Vendor libraries (e.g.,
libmmcamera2_isp2.so) were 32-bit, but the kernel was now 64-bit. The solution was to ship bothlib(32-bit) andlib64(64-bit) variants—a practice called “dual blob” .
From a driver perspective, the MSM8953 is a complex heterogeneous system: 8 identical A53 cores but different power domains, a separate DSP (Hexagon 546), an ISP, and a GPU. Each block requires a dedicated ARM64 driver.
- ARM64 status: ✅ Perfect.
The MSM8953 uses the pinctrl-msm driver. If you are developing a driver for a new sensor or button, you must define the pin configuration (bias, drive strength, and function) in the pinctrl section of your ARM64 device tree. 2. Power Management (RPM)
