Mir, the Canonical CLA and skewing the playing field

Filed under

Ubuntu

Like many Canonical-led projects, Mir is under GPLv3 - a strong copyleft license. There's a couple of aspects of GPLv3 that are intended to protect users from being unable to make use of the rights that the license grants them. The first is that if GPLv3 code is shipped as part of a user product, it must be possible for the user to replace that GPLv3 code. That's a problem if your device is intended to be locked down enough that it can only run vendor code. The second is that it grants an explicit patent license to downstream recipients, permitting them to make use of those patents in derivative works.

One of the consequences of these obligations is that companies whose business models depend on either selling locked-down devices or licensing patents tend to be fairly reluctant to ship GPLv3 software. In effect, this is GPLv3 acting entirely as intended - unless you're willing to guarantee that a user can exercise the freedoms defined by the free software definition, you don't get to ship GPLv3 material. Some companies have decided that shipping GPLv3 code would be more expensive than either improving existing code under a more liberal license or writing new code from scratch.

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).
