Msm8953 For Arm64 Driver Here
The Qualcomm MSM8953 (Snapdragon 625/450/626/632) is a highly versatile, ARM64-based octa-core SoC from 2016. Due to its prevalence in Android devices and IoT applications, it has robust community-driven Linux support, including mainlining efforts for modern kernels postmarketOS Wiki
One of the biggest hurdles in MSM8953 driver development is the gap between "Downstream" and "Mainline." msm8953 for arm64 driver
The MSM8953, popularly known as the Qualcomm Snapdragon 625, is a 64-bit octa-core system-on-chip (SoC) based on the arm64 (ARMv8-A) architecture. Driver support for this platform has transitioned from legacy Android vendor kernels to active "mainlining" efforts in the Linux community, enabling it to run modern Linux distributions like postmarketOS. Architecture & Hardware Overview CPU: Eight ARM Cortex-A53 cores running at up to 2.0 GHz. Kernel Driver : The MSM8953 kernel driver is
To prepare a paper or technical guide for developing an MSM8953 (Snapdragon 625) keep in mind the following:
The MSM8953 utilizes a 64-bit ARMv8-A architecture, specifically eight Cortex-A53
- Kernel Driver: The MSM8953 kernel driver is responsible for managing the processor's hardware components. You can find the kernel driver source code in the Qualcomm Linux kernel repository or the Android Open Source Project (AOSP) repository.
- Device Tree: The Device Tree is a data structure used to describe the hardware components of a system. For MSM8953, you'll need to create or modify a Device Tree file (
.dtsor.dtb) to describe the processor's peripherals and memory layout. - ARM64-specific considerations: When developing the MSM8953 driver for ARM64, keep in mind the following:
- AArch64 cross-compiler:
aarch64-linux-android-(from NDK) oraarch64-linux-gnu- - Kernel source: version 4.9 or 4.14 (backported)
- AArch64 cross-compiler:
