OSS

Open-source computers have so far lacked good graphics, but Gizmosphere’s new Gizmo 2 is an exception.

The Gizmo 2 is an uncased single-board computer that will sell for $199. The computer can be used to build robots, electronics with large screens, or interactive computer systems that can recognize gestures or images.

Linux

Following the recent Btrfs RAID: Native vs. Mdadm comparison, the dual-HDD Btrfs RAID benchmarks, and four-SSD RAID 0/1/5/6/10 Btrfs benchmarks are RAID Linux benchmarks on these four Intel SATA 3.0 solid state drives using other file-systems -- including EXT4, XFS, and Btrfs with Linux 3.18.

Intel Has More Graphics Changes Ready For Linux 3.19

Filed under
Graphics/Benchmarks

Daniel Vetter has sent in his latest drm-intel-next pull request for DRM graphics driver code targeting the Linux 3.19 kernel.

There's just 2~3 weeks until DRM-Next is closing early again for Linux 3.19 so Vetter on Monday sent in another pull request. There's already been new code queued up that includes initial hardware enablement for Skylake while more code is ready now.

The latest batch of Intel DRM changes for the next kernel cycle include suspend/resume/freeze/thaw unification work, WA list improvements, more kernel documentation of the i915 driver code, 180 rotation support for cursors, and many fixes all over the place.

Atomic Mode-Setting Moves Along For KMS Drivers

Graphics/Benchmarks
Linux

Vetter posted his atomic mode-setting patch series in latest form on Sunday. There's the helper libraries for migrating over to atomic mode-setting and the other core/driver interface changes for this work. The description on his latest patch series is quite lengthy so check it out if you're wanting to learn some more. These patches though don't offer the actual atomic mode-setting ioctl to expose to user-space.

NVIDIA's Linux Driver On Ubuntu 14.10 Can Deliver Better OpenGL Performance Than Windows 8.1

Filed under
Graphics/Benchmarks

The same Intel Core i7 4770K system used for yesterday's Windows vs. Linux graphics benchmarks were used when benchmarking the GeForce GTX 780 Ti, 970, and 980 graphics cards. Windows 8.1 Pro x64 had all available system updates at the time and was running the NVIDIA 344.48 WHQL binary driver that was their latest release at the time of testing. When running Ubuntu 14.10 x86_64 on the system with its Linux 3.16 kernel, the NVIDIA 343.22 driver was used. The 343.22 driver was the latest publicly available proprietary Linux driver at the time of testing and their first to support the GTX 970/980 under Linux. All of the same hardware was used under each operating system and each OS was with its software default settings as were the driver settings.

Has The Sky Fallen? Qualcomm Contributes To Freedreno's DRM/KMS Driver

Filed under
Graphics/Benchmarks

In an interesting change of events, Code Aurora on the behalf of the Qualcomm Innovation Center has added Adreno A4xx product support to the Freedreno-spawned DRM/KMS "MSM" driver.

Rob Clark started the Freedreno project over two years ago as a reverse-engineered project around Qualcomm's Adreno hardware. At the time Rob was working for Texas Instruments but now is employed by Red Hat. The Freedreno driver has largely been developed just by Rob with contributions by a few others, but without any official support from Qualcomm. Freedreno is to Adreno hardware as Nouveau is to NVIDIA hardware. Like Nouveau, Rob developed Freedreno code through clean-room reverse engineering.

Windows 8.1 vs. Ubuntu 14.10 With Intel HD Graphics

Filed under
Graphics/Benchmarks
Linux
Microsoft

For those curious how the latest open-source Intel Linux graphics driver is performing against Intel's newest closed-source Windows OpenGL driver, we've put Ubuntu 14.10 (including a second run with the latest Linux kernel / Mesa) against Microsoft Windows 8.1 with the newest Intel GPU driver released earlier this month.

As I've been mentioning on Twitter, fresh Windows 8.1 vs. Ubuntu 14.10 benchmarks are coming in the days ahead with Intel HD Graphics, AMD Radeon, and NVIDIA GeForce hardware. With the AMD/NVIDIA tests it includes the closed-source, binary drivers for Linux too. The Intel Haswell graphics results are up first since that's the most straight forward with Intel's Linux graphics support only coming through via their open-source driver.

Btrfs On 4 x Intel SSDs In RAID 0/1/5/6/10

Filed under
Graphics/Benchmarks

These results are much more interesting than the earlier two-disk HDD benchmarks now using solid-state storage and having bought four Intel Series 530 120GB SSDs for making this an interesting RAID comparison. Four of the Intel SSDSC2BW120A4K5 solid-state drives were used in their 120GB capacity. Each of these solid-state drives retail for $75~80 USD and features sequential reads up to 540MB/s and sequential writes up to 480MB/s with its Serial ATA 3.0 interface. The 2.5-inch SSD 530 Series drive is rated by a five-year warranty and uses 20nm Intel NAND MLC memory.

Android Leftovers

  • OnePlus Will Reveal Details Of Its ‘Oxygen’ Android ROM On February 12
    OnePlus introduced its own version of Android for its One smartphone earlier this month in response to its standoff with Cyanogen, and now the company has revealed that it will unveil its own ROM which can be installed on third-party Android devices on February 12. Correction: OnePlus tells us that, in fact, it won’t launch the ROM on the 12th. This is a tease-of-a-tease, and instead we can expect to see “more information about the ROM” not an actual download for third-party Android devices.
  • Android is suddenly surrounded by enemies
    Cyanogen is one of these forks. It has just raised $70 million from a number of investors including Microsoft to continue producing its own version of Android that it can position as a direct competitor to Google's.

    You might want to think twice before sending that sensitive text message over your supposedly secure Blackphone. A security flaw discovered by an Australian communication security expert could have allowed attackers to decrypt a Blackphone user’s messages, gather location information, and run additional code of the attacker’s choosing.

    A smartphone marketed as the most anti-surveillance, NSA-proof personal device – the BlackPhone – has been found vulnerable to a simple SMS attack that allows the hacker to steal contacts, decrypt messages, and even take full control of the device.
