Camera Subsystem on Qualcomm Platforms Under the Hood

This presentation provides an in-depth overview of Qualcomm's camera subsystem IP evolution, tracing its development from a simple ISP controller to a complex network of interconnected hardware components. Explore how the increasing complexity of Qualcomm camera IP has necessitated significant reworks in the CAMSS device driver within the Linux kernel. Learn about the Qualcomm camera subsystem architecture, its associated controllers, and understand both the legacy support and recent modifications to the CAMSS driver that aim to manage the hardware ISP complexity in the upstream Linux kernel.
