Graphics, sound and multimedia • Re: Map of RPi5 HVS registers

I still haven't quite got my head around how/why the RPi5 splits the video hardware across multiple `dri` cards/devices

i think the pi5 has at least 3 dri devices

one is the 3d core, all it does is turn textures+shaders+polygons into 2d images
one is the bcm2712 2d core, it deals with the HVS, pixel valves, and hdmi
and one is the RP1 2d core (check the RP1 datasheet), it deals with DSI, DPI, and VEC(ntsc/pal)


ive also made many demos of driving the HVS on the pi0-pi3 family
but i havent done much testing on the pi4 or pi5 yet
