Porting Graphical Stacks to RISC-V using QEMU and Yocto

on YouTube ↗11m

" summary

Port of Plasma Mobile to RISC‑V using QEMU virt and Yocto layers builds a full graphical stack: Linux kernel guest, meta-riscv plus meta-qt5 and KDE frameworks, tested with virtual PCIe/vGPU and VGA. Matchbox terminal and XFCE boots succeed; Plasma Mobile reaches KDE runtime but hits a segfaulting Qt compositor leaving a blank screen and USB keyboard/mouse not delivering input though cursor is visible. Ongoing work is kernel/Qt fixes, upstreaming patches and moving to real hardware.
