Re: Easily run 64-bit Debian Stretch packages on a Raspbian system: new RPi3 demo image released (systemd-nspawn, LXDE)

sakaki has a GitHub repository where she provides a frequently updated 64-bit kernel for the Raspberry Pi 3. If you want to update your kernel, you should update it from that repository.

Re: Debian Stretch ARM64 for Raspberry Pi 3

Seems like what I said was false. The kernel I used in my Debian images (4.18 or 4.19, I can't remember) seems to be at fault for the overlay not working. I tried building a test Debian XFCE ARM64 image for the Pi 3 that used kernel 4.14.95 and then enabling OpenGL in config.txt and the Pi booted us...

Re: TUTORIAL: Enabling KVM virtualisation on the Raspberry Pi 3

sakaki's tutorial will also work on other Linux distros for the Pi 3 such as Debian with this KVM-enabled kernel. It will also work on x64 hosts without KVM enabled but will be slower than on actual ARM64 hardware.

Re: FreeBSD with Wireless support for Raspberry RPI3 ?

Drivers for the Pi 3's built-in WiFi are available, but only for Linux. FreeBSD is Unix, which is similar to Linux, but also different in many ways. The Raspberry Pi hardware is not 'free' so the FreeBSD devs can't code their own drivers.

Re: Easily run 64-bit Debian Stretch packages on a Raspbian system: new RPi3 demo image released (systemd-nspawn, LXDE)

You should be able to do the same from armhf Debian. It should follow then that you could use armhf raspian packages and Debian arm64 packages together with a multiarch setup. The generic Debian kernels are bootable on the pi, you just need to change the fat partition so that it is mounted as /boot...

Re: Raspberry PI OS for Desktop ... LXDE issue

Point releases are simply made so that users don't have to perform so many updates after installation. Ubuntu 18.04.2 is going to be released on the 7th of February, so if you download Ubuntu on the 8th of February and then install it, few (if any) updates will need to be installed.

TUTORIAL: Enabling KVM virtualisation on the Raspberry Pi 3

KVM is an accelerator which can be used with QEMU to run guests of the same architecture as the host at accelerated speed. On x64 PCs, this can be enabled in the BIOS if the CPU supports it (I am aware that some Intel Atom CPUs do not). However, the Pi does not have a BIOS, and there is no config.tx...

Well Pi's only have OpenGLES hardware but I'm running an OpenGL Desktop.
The Pi 2 and 3 do support OpenGL through an experimental driver. The driver is far from production-ready, but it does provide hardware acceleration through the VC4 GPU.

Re: Spider-OS a new operating system

Suggestions:

1. Make OS ARM64 to take full advantage of the Pi 3's SoC.
2. Include basic stuff such as a web browser, notes program, calculator, calendar, and clock.

Does this OS support the built-in WiFi provided by the Pi 3?

Great work! With this image, you get to keep all your familiar Raspbian 32-bit programs, while being able to run 64-bit Debian programs as well. This gives you the latest versions of Chromium and Firefox which aren't present in the Raspbian repositories. You get the efficiency of a 64-bit OS while s...

Re: Run another OS on your RPi3 as a virtualized QEMU guest under KVM (64-bit)

Unfortunately, KVM under 1GB RAM is quite restrictive. At most, you'll be able to allocate 600MB RAM to your VM and that will make your host system very slow. We'll need a Pi with at least 2GB RAM before we can make more use out of KVM. But good tutorial. I'm assuming that this can also be done on a...
