Msm8953 For Arm64 Driver ❲FRESH — Report❳

Missing from mainline:

Getting a functional ARM64 driver stack on the MSM8953 requires moving away from the "downstream" (Android-specific) 3.18 or 4.9 kernels and toward the (current stable releases). 1. Device Tree (DT) Configuration msm8953 for arm64 driver

A dedicated hardware subsystem using a separate microcontroller. Drivers communicate with the RPM via a messaging interface ( qcom,smd-rpm ) to scale voltage regulators (RPM-regulator) and system clocks. Missing from mainline: Getting a functional ARM64 driver

The display driver for MSM8953 was responsible for managing the MDP (Mobile Display Processor) and DSI (Display Serial Interface). It had to handle complex tasks such as dynamic refresh rates, resolution negotiation, and power management for the screen. Because this driver was deeply intertwined with the proprietary "firmware" loaded onto the Adreno GPU, open-source support was historically fragmented. For years, developers porting newer versions of Android to MSM8953 devices struggled with "fragmentation" issues where the kernel driver expected certain firmware blobs that were incompatible with newer userspace graphics libraries.
