The CFE works on 2 pixels/clock, so with overheads we get a (non-overclocked) throughput of just under 400 MPix/s. The libcamera pipeline handler will complain loudly if the pixel rate goes above this and attempt to adjust HBLANK to reduce the line rate.I'm also surprised that 4032x3040 10bit @30fps (367MPix/s) works through the CFE as when testing with IMX258 we found that it was limited to 250MPix/s as that is the internal clock of RP1.
