One Laptop Per Child: XO Phase 2

Filed under
OLPC

One Laptop Per Child project is currently working on the “Build 2″ (B2) release of their “XO”laptop (the name comes from a characteristic symbol representing the user in the interface: a circle above the cross). The first pieces of the B1 series have been produced in November last year. The B2 prototypes are planned to be delivered to the interested countries for practical testing this month.

Recent architecture changes

During this period of time, there have been some noticeable changes in the XO project. We are going to cover the essential ones here.

Wireless drivers

The wireless driver used for XO is supposed to become part of the default Linux kernel. The kernel developers managed to decrease the number of interruptions from 200/s to 5-6/s. This optimization should help to lower the energy consumption of the card.

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).
