Msm8953 For Arm64 Driver High Quality Fixed Link

Mastering the MSM8953: A Guide to High-Quality ARM64 Driver Development

3.1. Clock and Reset Control

• Implement pm_runtime_get_sync/put_autosuspend when reading sensors.
• Set autosuspend_delay_ms to a reasonable default.

Camera (ISP) and MIPI CSI

Low-quality drivers manifest as:

3. Bus Bandwidth and Interconnects

Modern SoCs like the MSM8953 utilize an internal NoC (Network on Chip). High-quality display and camera drivers cannot simply write to memory; they must vote for bandwidth. For the MSM8953, developers should implement the interconnect framework. This ensures that when the GPU (Adreno 506) or VFE (Video Front End) requires high data throughput, the system bus (SNOC/PCNOC) is scaled up accordingly, and scaled down during idle to save power. Failure to implement this results in "starvation" artifacts or excessive heat. msm8953 for arm64 driver high quality
