Msm8953 For Arm64 Driver [updated] Jun 2026
The foundation of any driver on ARM64 is the . For the MSM8953, the hardware is described in arch/arm64/boot/dts/qcom/msm8953.dtsi .
In the ARM64 Linux ecosystem, hardware is not self-discoverable. The kernel relies on a Device Tree Source file ( .dts or .dtsi ) to map out memory addresses, interrupts, and clocks.
This compiles the compressed kernel image, device tree blobs (DTBs), and kernel modules. 4. Challenges in Driver Development msm8953 for arm64 driver
For developers, there are efforts to run mainline Linux on MSM8953 via postmarketOS , which supports features like CPU frequency scaling and eMMC storage. Mainlining - postmarketOS Wiki
Adding missing clock-frequency properties in the device tree ( dts ) to ensure components operate at their intended, efficient speed. If you can tell me: The foundation of any driver on ARM64 is the
This is standard ARM IP. The MSM8953 uses – enable ARM_GIC in your defconfig. No surprises here.
Are you facing any specific during the compilation or probing phase? The kernel relies on a Device Tree Source file (
The GPU is Adreno 506 (part of the Adreno 5xx family).
What are some difficulties in mainlining Qualcomm chip drivers into the Linux kernel?
In the sprawling ecosystem of ARM64 System-on-Chips (SoCs), few platforms have achieved the legendary status of Qualcomm’s . Codenamed "Sdm439" in later iterations but more famously known as the Snapdragon 625 – and its clock-bumped sibling, the Snapdragon 626 – this 14nm FinFET chipset powered hundreds of millions of devices between 2016 and 2020. From the Xiaomi Redmi Note 4 to the Moto Z Play and the Asus Zenfone 3, the MSM8953 became synonymous with battery efficiency and reliable performance.
Because it was designed for ARM64 and possesses decent power efficiency, the MSM8953 remains a popular choice for community-driven development, specifically for running mainline Linux, postmarketOS, and Ubuntu Touch. This guide covers the state of ARM64 drivers for the MSM8953, the path to mainlining, and how to work with these drivers. 1. Overview of MSM8953 (Snapdragon 625) Architecture The MSM8953 platform is a "system-on-chip" that includes: 8x ARM Cortex-A53 (ARM64 architecture) GPU: Adreno 506 DSP: Hexagon 546 Modem: Snapdragon X9 LTE Display/Camera: Qualcomm Adreno 506/MDSS
