Msm8953 For Arm64 Driver Here

If you are developing a new driver for this platform, always test on actual hardware (e.g., DragonBoard 625c or a cheap MSM8953 phone) and use dmesg to debug ARM64-specific issues like alignment faults or 32-bit syscall compatibility.

CONFIG_DRM_MSM=y CONFIG_DRM_MSM_MDP5=y CONFIG_DRM_MSM_DSI=y

Use kernel 4.9 (minimum) with Android common patches. Recommended repo: LineageOS kernel_xiaomi_msm8953 (updated for 64-bit binder). msm8953 for arm64 driver

Demystifying the MSM8953 (Snapdragon 625) Architecture and ARM64 Driver Porting

Here is a breakdown of the driver landscape for the MSM8953 on the ARM64 architecture. If you are developing a new driver for

In the ARM64 Linux ecosystem, drivers do not discover hardware at runtime. Instead, the kernel reads a Device Tree Blob (DTB). For MSM8953, the hardware description is split across several files in the kernel source tree under arch/arm64/boot/dts/qcom/ . Key DTS Components

For the MSM8953, the entry point file in the mainline Linux kernel is typically located at: arch/arm64/boot/dts/qcom/msm8953.dtsi For MSM8953, the hardware description is split across

Drivers use the standard Linux Regulator API framework ( regulator_get , regulator_enable ).

# 1. Set the architecture environment variables export ARCH=arm64 export CROSS_COMPILE=aarch64-linux-gnu- # 2. Load the default Qualcomm multiplatform configuration make defconfig # 3. Compile the kernel, modules, and device tree blobs make -j$(nproc) Image modules dtbs Use code with caution.
