I think the main issue keeping the pi with a 32b userspace is the lack of availability of 64bit GPU firmware

  The fully open source driver stack can't some soon enough. (yes I know firmware files still exist, but they don't prevent you from running a 64 bit kernel and userspace)

  > I think the main issue keeping the pi with a 32b userspace is the lack of availability of 64bit GPU firmware Uh, no. It's there because of the design goals and priorities of the Foundation. They want to be able to distribute a distribution that runs on any raspberry pi generation. Performance is of secondary concern to them. So Raspbian remains at 32-bit.

    Can you cite a source for this claim?

        > this will be combined with a 32bit userland, for the reason mentioned above. - the amount of work needed to update all the libraries that talk to the GPU.

          My eyes kinda glaze over when I see that because the vc4-fkms-v3d driver works fine enough with mesa on 2D and 3D shit using a full 64-bit system. Maybe it's not as fast as the original proprietary driver, I don't know as I've never used the original proprietary one nor have I seen anyone benchmark it.
