Most MSM8953 boards (like the DragonBoard 410c's bigger brothers or repurposed phones) output kernel logs via UART. This is essential for debugging "kernel panics" before the display driver initializes.
Writing display drivers for ARM64 Qualcomm chips involves the . In the mainline kernel, this is handled by the msm DRM driver. It manages the DSI (Display Serial Interface) lanes to push pixels to the panel. Development Tips msm8953 for arm64 driver
The MSM8953 relies on the . Drivers for this SoC often communicate with the RPM via a messaging protocol (SMD or GLINK) to request clock speeds or voltages. Without a functional RPM driver, the SoC will often stay in its lowest power state, leading to sluggish performance. 3. Display (DSI/MDP) Most MSM8953 boards (like the DragonBoard 410c's bigger
