Krita progress over the past few months has been slower than I’d have liked, for a couple of reasons: porting to Qt4 was quite hard. But! Banish the gloom! There are some really cool and interesting developments. Not only have we got a most impressive ToDo, sometimes items even get done! I already mentioned the flake integration. But there’s more…

Casper Boemann moved Krita’s color model library from Krita to KOffice proper, renaming it to Pigment. Then Cyrille Berger refactored it to use C++ templates, something that has been on the ToDo for a long, long time. The result? When I casually mentioned that having a 16 bits XYZ colorspace would be nice to have, Cyrille committed one in less than an hour.

I have been working on multithreading and on the canvas. Recompositing the image now happens in threads, and I’ve ported Gwenview’s excellent and fast scaling.

Ryzen 7 2700X CPUFreq Scaling Governor Benchmarks On Ubuntu Linux

With this week's Ryzen 5 2600X + Ryzen 7 2700X benchmarks some thought the CPUFreq scaling driver or rather its governors may have been limiting the performance of these Zen+ CPUs, so I ran some additional benchmarks this weekend. Those launch-day Ryzen 5 2600X / Ryzen 7 2700X Ubuntu Linux benchmarks were using the "performance" governor, but some have alleged that the performance governor may now actually hurt AMD systems... Ondemand, of course, is the default CPUFreq governor on Ubuntu and most other Linux distributions. Some also have said the "schedutil" governor that makes use of the kernel's scheduler utilization data may do better on AMD. So I ran some extra benchmarks while changing between CPUFreq's ondemand (default), performance (normally the best for performance, and what was used in our CPU tests), schedutil (the newest option), and powersave (if you really just care about conserving power).
