[$] Unaddressable device memory

10 hours 47 min ago
In a morning plenary session on the first day of the 2017 Linux Storage, Filesystem, and Memory-Management Summit, Jérôme Glisse led a discussion on memory that cannot be addressed by the CPU because it lives in devices like GPUs or FPGAs. There is often a substantial pile of memory on these devices and it can be accessed much more quickly by the devices than the system RAM can be. Making it easier for user-space programmers to use that memory transparently is the goal of the heterogeneous memory management (HMM) patches that Glisse has been working on.

Garrett: A new Shim review process

11 hours 30 min ago

O-MG, the Developer Preview of Android O is here! (Android Developers Blog)

Tuesday 21st of March 2017 08:39:33 PM
The Android Developers Blog introduces the first developer preview of Android O. This version includes background limits, notification channels, autofill APIs, PIP for handsets, font resources in XML, adaptive icons, and much more. "Building on the work we began in Nougat, Android O puts a big priority on improving a user's battery life and the device's interactive performance. To make this possible, we've put additional automatic limits on what apps can do in the background, in three main areas: implicit broadcasts, background services, and location updates. These changes will make it easier to create apps that have minimal impact on a user's device and battery. Background limits represent a significant change in Android, so we want every developer to get familiar with them."

Ubuntu: A follow-up on 32-bit powerpc architecture

Friday 17th of March 2017 06:27:20 PM
Ubuntu has discontinued support for the 32-bit powerpc architecture in Zesty Zappus (17.04). "We are well into Feature Freeze at this point, so an update is overdue. As of Feature Freeze in February, the status is that powerpc packages are no longer considered for proposed-migration, and we have discontinued all CD image builds for powerpc in zesty. For the moment, uploads continue to be built for powerpc in Launchpad, and packages are still published in the archive. You should expect both to be discontinued before the 17.04 release."

It's the scheduler latency that we're more interested in tuning."

  • Device Tailored Compositors with Qt Wayland at CLAAS E-Systems
    Have you heard about software in cars that run on embedded devices? Do you think that creating such software might be challenging? Well, welcome to a complete new world of complexity, welcome to the world of agriculture machines! For many years, automatic steering (on fields), terminals to control the complex mechanical operations of a self-driving 16 ton combine harvester on a soft ground, and self-optimization systems to optimize any tiny bit of your harvester, are key demands from customers. I, myself, am working at CLAAS E-Systems, the electronics and software department within the CLAAS group. Our group is well known for being among the leading manufacturers for combine harvesters, tractors and forage harvesters.
  • Qt Wayland Is Next Appearing On Tractors & Farm Equipment

One of those is a company specializing in farm equipment like combine harvesters, tractors, and harvesters. As a guest post on the official Qt blog, developer Andreas Cord-Landwehr of CLAAS E-Systems talked up Qt Wayland for their purposes in the highly-regulated agriculture industry.
