Probably some, but not to the degree that you may think. This relies on DMA in the CSI controller, but only a fraction of a pi4's RAM is accessible by DMA. Ba

Probably some, but not to the degree that you may think. This relies on DMA in the CSI controller, but only a fraction of a pi4's RAM is accessible by DMA. Basically from the video core side, there's only a 32-bit bus to main memory, and it has to share that with MMIO space and there's mirrors with/without caching sort of like a MIPS. Probably maxes out after a couple GB or so.
