Re: 64-bit weekly kernel autobuilds for RPi4 released (bcm2711_defconfig)

Yes, edit /boot/config.txt and comment out the arm_64bit=1 line.

Edit: I didn’t realize this was the other kernel thread. You may run into issues because there’s another line kernel=kernel8-pi4.img to be undone. You’ll probably have an easier time getting and using 64-bit kernels via rpi-update.

Re: How to setup Dolphin on a Pi 4 with Raspbian Buster

Strange, Gentoo should be even easier to run with GLES because it already comes with the correct build of Mesa. My initial guess would be a spacing or other formatting issue in your GFX.ini, but if PreferGLES = True weren't getting picked up you would have seen some obvious dialog errors complaining...

If on Raspbian, armhf Docker won't run arm64 containers. I reported on GitHub: https://github.com/docker/distribution/issues/3008 but it's unlikely to get any attention soon. LXC, systemd-nspawn, or chroot have no trouble spawning a 64-bit environment from a 32-bit userland, so the problem is specif...

It supposedly brings everything into OPENGLES 3.1 compliance and gets EXT_BUFFER_STORAGE working
The kernel update won't do that alone. You need Mesa built off that specific branch as well.

Welcome to the forums. It appears you attempted to run directly on Raspbian's userland rather than a 64-bit chroot or container. This would not only fail to run java arm64, but any aarch64 binary. Instructions for setting up a 64-bit userland environment (chroot or systemd-nspawn container) mentione...

Connecting the DS4 to the Pi is straightforward, but having the Pi talk to the PS4 is not.

Looking at https://github.com/raspberrypi/linux/pull/3203 the kernel fix landed on Friday, so once rpi-update gives you 4.19.74-v8+ or newer it'll contain that required patch. As for the Mesa update, even when v3d-gles31 gets merged and libgl1-mesa-dri is updated in the Raspbian repo it'll be 32-bit...

after doing 'rpi-update', it rebooted so that 'uname -a' reports 'aarch64'. However, 'getconf LONG_BIT' reported '32'. But then, 'lscpu' says 'aarch64'. gcc however still compiles to 32-bits, and there doesn't seem to be a way to update it. A newly downloaded tcc said its '-m64' option was not impl...
