Good. Most core functionality works on modern mainline kernels (6.x+). Core Drivers: msm8953 for arm64 driver

PMIC drivers allow battery level reporting and charging, though sometimes require specialized DT patches.

Venus driver works for encode/decode, supporting 1080p60 on SDM450 and 4K30 on SDM625. WCN36xx driver provides Wi-Fi/Bluetooth support. postmarketOS · GitLab 2. Community Resources & Mainline Efforts : Ensure that your driver calls clk_prepare_enable() on

Modern Linux has native support for the MSM8953 platform ( arch/arm64/boot/dts/qcom/msm8953.dtsi ). Mainline drivers use standard Linux frameworks like pinctrl-msm , regmap , and generic RPM (Resource Power Manager) clock drivers.

The true potential of the MSM8953 is unlocked in the ARM64 (AArch64) architecture. While its journey in the mainline Linux kernel has been measured, it is now reaching a state of maturity. For developers, system integrators, and enthusiasts, building a kernel for an MSM8953 device has transitioned from a work-in-progress to a practical reality.

This article breaks down how the MSM8953 interacts with the Linux ecosystem, the challenges of driver support, and the journey to mainline the SoC. 1. The Architectural Blueprint: Understanding MSM8953

Driver support for MSM8953 varies significantly between original vendor releases and community-driven upstreaming: Device msm8953 for arm64
