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.
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.
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.
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.
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.
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.
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.
