  • What is hello_pi that I find in /opt/vc?

    From Chris Green@3:770/3 to All on Wed Aug 4 12:47:37 2021
    I was just looking at what uses space on my DNS server Pi and found
    that there is a program (suite?) called hello_pi installed in /opt/vc.

    Is this something that comes with a standard Pi installation or is it
    something I installed a long time ago and forgot about? The README
    file just tells how to build it, not what it does.

    I see it's also on my other Pi (backup server) so I guess it must come
    with the standard Pi installation.

    I assume I can just remove it?

    /opt/vc is where the demo programs for the VideoCore, the Pi's GPU, live. Originally they were a collection of video playing/3D graphics/etc demos.
    As shown by the link posted in this thread, they're also been used for tutorials about how to run things, but that wasn't the original intention.

    (the 2011 Pi prototype had them there, so I think they were part of the original Broadcom SD image, pre-Raspbian, and they've been kept in the image)
