KDE and Plasma on ARM The Plasma developers worked on running KDE on a so-called "mystery device", a working name for a class of relatively low-performance devices based on the ARM architecture. As a reference device, the developers used a 800 Mhz ARM CPU with 512MB of RAM. During the sprint, KDE 4.2's Plasma was presented running on the device. The overall performance was quite good, although it showed room for improvement. Even without having an accelerated graphics driver available at this point, the developers were quite happy with the performance so far as Souza a.k.a Morpheuz reports on his weblog. Using Qt 4.6 on the device gave another boost in speed. "Even with the short time available to make Plasma run on the device, and without having a proper graphics driver available, we can now be sure that running Plasma on this class of devices is absolutely feasible. I'm sure that, with a bit more integration work, Plasma will offer a premium choice for UI technology on this new class of devices." concludes Souza.
