    Re: No 3D acceleration on Raspberry Pi 4

    Yes .... got the 1014 kernel update and now the V3D 4.2 pi driver is showing as in use, so fixed.
    Clearly some change to the kernel has been included/picked up as a patch and has fixed the issue.

    may indicate that the V3D driver is not starting up correctly and generating the required /dev/ entries.
    The first line appears to indicate that the probe has not received the expected number of output ports which then appears to remove the /dev entries.
