== KDE Yocto Demo Setup for FOSDEM 2024 ==

This page provides the basic information about the demo setup that is available at the KDE stall at FOSDEM 2024.

=== What can I see there? ===

* a Raspberry-Pi5 development board
* a OLED HDR touch screen
* a Plasma mobile Yocto image with KDE Frameworks / Plasma / Applications in RC-2 version of the Qt6 Megarelease

=== What is this demo setup about to present? ===

* show the state of the Yocto meta-layers: read mere at https://community.kde.org/Yocto
* give a feeling about how Plasma Mobile feels on an embedded non-phone device
* give a sneak-peak into Plasma 6
* give an example of how such embedded boards can be used

=== FAQ ===

# Why is the demo not on RISC-V hardware?
#* Because for no RISC-V board (at least to those we have access) the GPU driver is stable enough to handle a Wayland compositor together with complex QtQuick applications; on VisionFive-2 there are apparent GPU-CPU race conditions that very fast lead to severe artifacts that are no fun for a demo
# Why is this running Yocto master?
#* Because the RPi5 device support (just merged some days ago) only booted with Yocto master

== Details ==
=== Hardware ===
Details: https://www.raspberrypi.com/documentation/computers/raspberry-pi-5.html#introduction

Most important facts:
* Quad Arm Cortex-A76 @ 2.4GHz
* 8GB LPDDR4X-4267 SDRAM
* VideoCore VII graphics, with OpenGL-ES 3.1, Vulkan 1.2

=== Software ===
* running Yocto Master (Poky & meta-openembedded)
* meta-raspberrypi latest master version that just got RPi5 support merged.
