Many recent Windows (on ARM and x86) laptops have replaced the standard UVC USB camera module with a raw MIPI camera-sensor using a CSI receiver and ISP in the CPU to process the raw data into an image (and on smartphones this has been the norm for ages).
Supporting these cameras under Linux is an ongoing challenge. At FOSDEM 2024 a solution using a software ISP running on the CPU was presented as a solution to get these cameras to work with a fully opensource stack.
This talk will look at where support for MIPI cameras using the software ISP is at now, 1.5 years later, mainly focusing on the ubiquitous x86 laptops using cameras connected to Intel's IPU6.
Depending on ongoing work this will include a demo of recent developments such as running the software ISP on the GPU and the first FOSS color-corrected images from an IPU6 attached sensor with the color calibration done using all FOSS tools.
