Interfacing (DSI, CSI, I2C, etc.) • DSI Encoder and DSI Packet in Raspberry Pi 5

Hi,

I am trying to learn MIPI DSI through raspberry pi. Is the DSI encoder in raspberry pi 5 hardware type or software type? I would like to play around with different DSI configuration(mode, color format, timing parameters) and see how DSI packet changes. I saw there are many settings like the color format and drm_display_mode being configured in rp1dsi_dma_setup() using rp1dsi_dma_write() but not sure where the conversion of pixel format into DSI package takes place.

Is it possible to read or trace the DSI packet inside linux kernel? Or I need a logic analyzer to read it?

Thanks.
