[$] Unaddressable device memory

Wednesday 22nd of March 2017 02:32:24 PM
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

Wednesday 22nd of March 2017 01:50:14 PM
Matthew Garrett announces a new, hopefully more efficient process for reviewing bootloaders to be used with Shim in UEFI secure boot systems. "To that end, we're adopting a new model. A mailing list has been created at shim-review@lists.freedesktop.org, and members of this list will review submissions and provide a recommendation to Microsoft on whether these should be signed or not."

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."

[$] ZONE_DEVICE and the future of struct page

Tuesday 21st of March 2017 12:59:06 PM
The opening session of the 2017 Linux Storage, Filesystem, and Memory-Management Summit covered a familiar topic: how to represent (possibly massive) persistent-memory arrays to various subsystems in the kernel. This session, led by Dan Williams, focused in particular on the ZONE_DEVICE abstraction and whether the kernel should use page structures to represent persistent memory or not.

The Intel Edison: Linux Maker Machine in a Matchbox (Linux.com)

Monday 20th of March 2017 07:21:43 PM
Linux.com takes a look at the Intel Edison. "The Intel Edison is a physically tiny computer that draws a small amount of power and breaks out plenty of connections to allow it to interact with other electronics. It begs to be the brain of your next electronics tinkering project, with all the basics in a tiny package and an easy way to connect other things you might need."

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."

Gregg: perf sched for Linux CPU scheduler analysis

Friday 17th of March 2017 05:38:05 PM
Brendan Gregg shows how to do scheduler profiling with the perf sched command. "perf sched timehist was added in Linux 4.10, and shows the scheduler latency by event, including the time the task was waiting to be woken up (wait time) and the scheduler latency after wakeup to running (sch delay). It's the scheduler latency that we're more interested in tuning."

  • Announcing the Shim review process [Ed: accepting rather than fighting very malicious things]
    However, a legitimate criticism has been that there's very little transparency in Microsoft's signing process. Some people have waited for significant periods of time before being receiving a response. A large part of this is simply that demand has been greater than expected, and Microsoft aren't in the best position to review code that they didn't write in the first place.

  • YaST Team: Highlights of YaST development sprint 32
    One of the known limitations of the current installer is that it’s only able to automatically propose an encrypted schema if LVM is used. For historical reasons, if you want to encrypt your root and/or home partitions but not to use LVM, you would need to use the expert partitioner… and hope for the best from the bootloader proposal. But the new storage stack is here (well, almost here) to make all the old limitations vanish. With our testing ISO it’s already possible to set encryption with just one click for both partition-based and LVM-based proposals. The best possible partition schema is correctly created and everything is encrypted as the user would expect. We even have continuous tests in our internal openQA instance for it. The part of the installer managing the bootloader installation is still not adapted, which means the resulting system would need some manual fixing of Grub before being able to boot… but that’s something for an upcoming sprint (likely the very next one).

  • Asus Tinker Board – Chromium YouTube Performance
    One of the many strengths of the Asus Tinker Board is its multimedia support. This 4K video capable machine is a mouthwatering prospect for the multimedia enthusiast. The machine has a respectable 1.8GHz ARM Cortex-A17 quad-core processor. It’s only 32-bit (unlike the Raspberry Pi 3) but has a higher clock speed. The Tinker Board also sports an integrated ARM-based Mali T764 graphics processor (GPU).
