Msm8953 For Arm64 Driver Online
Use an aarch64-linux-gnu- toolchain to compile the kernel and modules on an x86_64 host.
Often part of the Hardware Abstraction Layer (HAL), these provide standardized APIs (like OpenGL for the GPU or V4L2 for the camera) to the Android framework or Linux applications. Firmware/TrustZone:
Realistically, a fully functional mainline Linux ARM64 desktop on MSM8953 is – but the progress is tangible.
Vendor Android kernels typically use the msm8953_defconfig or msm8953-perf_defconfig inside the arch/arm64/configs/ directory. Upstream mainline configuration targets are defined in arm64/defconfig , where developers enable specific MSM8953 drivers like the interconnect driver, pinctrl, and specific touchscreen controllers. msm8953 for arm64 driver
Originally, MSM8953 shipped with Android 6/7 (32-bit kernels or 32-bit userlands). By Android 10, Google mandated . This broke every proprietary driver blob:
The Device Tree Source (DTS) is the backbone of ARM64 Linux hardware description. For MSM8953, the main Device Tree Include (DTSI) file is located at: arch/arm64/boot/dts/qcom/msm8953.dtsi
A properly structured MSM8953 ARM64 device tree node requires specific #address-cells and #size-cells properties set to to handle 64-bit addressing structures uniformly, even if the peripherals reside below the 4GB mark. Use an aarch64-linux-gnu- toolchain to compile the kernel
// Example of a Device Tree inclusion for MSM8953 /dts-v1/; #include "msm8953.dtsi" #include "msm8953-common.dtsi" // Shared configuration / model = "Xiaomi Redmi Note 4X"; compatible = "xiaomi,mido", "qcom,msm8953"; ; Use code with caution. 4. Building and Deploying the Kernel
As of 2024, mainline Linux (kernel 6.5+) has for MSM8953 thanks to the Qualcomm ARM64 platform maintainers. Notable drivers mainlined:
The you are targeting (e.g., camera, display, Wi-Fi, custom I2C device). By Android 10, Google mandated
