Nouveau Works On Maxwell Fan Management

Filed under
Graphics/Benchmarks

Nouveau developer Martin Peres has published a set of ten Nouveau DRM patches working towards proper fan/power management support for NVIDIA's latest "Maxwell" GPUs.

The patches by the long-time Nouveau contributor from France adds Maxwell support for fan management, changes to fan handling, PWM fan support (Pulse Width Modulation) support, and other power/fan related fixes and improvements.

AMD Compiler Optimization Benchmarks With GCC 4.10 (GCC 5.0)

Filed under
Graphics/Benchmarks

As a continuation to yesterday's brief GCC 4.9 vs. GCC 4.10 (GCC 5.0) comparison with the AMD A10 A-Series "Kaveri" APU, here's some benchmarks when using the GCC 4.10 development snapshot and trying a variety of CFLAGS/CXXFLAGS to see the current impact on their performance for a variety of Linux benchmarks.

GCC 5.0 Doesn't Show Much Difference Yet For AMD's Steamroller

Filed under
Graphics/Benchmarks

GCC 4.10 has been under development since the 4.9.0 release near the beginning of the year. However, at the GNU Tools Cauldron it was agreed upon that GCC 4.10 will most likely become GCC 5.0 upon its release in 2015. The GCC version scheme is also being shaken up for future releases. Years ago there was talk of GCC 5.0 being modular and more like LLVM but to date there's no "killer features" of GCC 5.0 at this point in its SVN code-base.

AMD Quietly Releases Catalyst 14.8 Linux Driver

Linux

Back on 8 August there was evidently the Catalyst 14.8 Linux driver replace to succeed the Catalyst 14.6 Beta that was last updated in mid-July. AMD didn't make any announcement about the 14.8 Linux driver update and we didn't even notice until now when a Phoronix reader stumbled across Catalyst 14.8.

Unfortunately AMD didn't publish a change-log for the Catalyst 14.8 Linux driver update so we're really not sure what (if any) significant changes made it into this latest release, but we would certainly assume there's more Linux game bug-fixes to be found in this newest version. Given it was released at the end of last week, there's not OpenGL 4.5 support expected. It's also likely too soon to expect any Linux 3.16 kernel compatibility.

Linux 3.17 Doesn't Do Much For AMD Kaveri's Graphics Performance

Filed under
Graphics/Benchmarks

Following yesterday's RadeonSI Gallium3D vs. Catalyst comparison using the new AMD A10-7800 Kaveri APU with Radeon R7 Graphics, I then upgraded to the latest Git code for the Linux 3.17 kernel to look for performance changes.

Trying The Configurable 45 Watt TDP With AMD's A10-7800 / A6-7400K

Filed under
Graphics/Benchmarks

AMD Kaveri APUs feature a configurable TDP whereby users can opt to run their A-Series APUs with a lower power consumption and operating temperature but at the cost of slightly reduced performance.

AMD Kaveri: Catalyst vs. RadeonSI Gallium3D On Linux

Filed under
Graphics/Benchmarks

With the recently released AMD A10-7800 Kaveri APU I carried out some new benchmarks comparing the open and closed-source Linux GPU driver performance for AMD with their Catalyst and RadeonSI Gallium3D solutions. When running the open-source Ubuntu driver tests, multiple versions of Mesa and the Linux kernel were used.

NVIDIA Already Publishes An OpenGL 4.5 Linux Driver

Graphics/Benchmarks
Linux

While the OpenGL 4.5 specification is fresh off the press and we haven't even seen the Khronos SIGGRAPH announcement yet, NVIDIA has already made public their OpenGL 4.5 beta drivers for Linux and Windows.

The NVIDIA 340.23.01 Linux driver is available today and provides beta support for OpenGL 4.5 and the OpenGL Shading Language (GLSL) 4.50 versions. For tapping all of the potential of OpenGL 4.5, a Fermi, Kepler, or Maxwell GPU is needed. This is conveniently the GeForce 400 series and newer, which is only what's supported now after NVIDIA dropped pre-Fermi support from their mainline Linux driver.

The Khronos Group Is Developing A New Graphics API From The Ground-Up

Filed under
Graphics/Benchmarks

Khronos announced a call for participation in a next-generation OpenGL initiative. The announcement reads, "Khronos announced a call for participation today in a project to define a future open standard for high-efficiency access to graphics and compute on modern GPUs. Key directions for the new ground-up design include explicit application control over GPU and CPU workloads for performance and predictability, a multithreading-friendly API with greatly reduced overhead, a common shader program intermediate language, and a strengthened ecosystem focus that includes rigorous conformance testing. Fast-paced work on detailed proposals and designs are already underway, and any company interested to participate is strongly encouraged to join Khronos for a voice and a vote in the development process."

Nouveau's Big Batch Of Changes Land In Linux 3.17

Filed under
Graphics/Benchmarks

Being merged into the mainline kernel code-base for Linux 3.17 was the big DRM feature pull that included enhancements to the Intel and AMD Radeon graphics drivers (among the other smaller DRM/KMS drivers), but missing from action was the open-source NVIDIA driver. The Nouveau driver changes were delayed by some last-minute bug-hunting but now a separate pull request was issued to land the Nouveau driver updates for Linux 3.17.

OpenForum Europe Challenges Governments to Walk the Open Format Walk

OpenForum Europe, an advocacy group focusing on IT openness in government, issued a press release earlier today announcing its launch of a new public Internet portal. At that site, anyone can report a government page that offers a document intended for collaborative use for downloading if that document is not available in an OpenDocument Format (ODF) compliant version. The portal is called FixMyDocuments.eu, and you can show your support for the initiative (as I have) by adding your name here (the first supporter listed is the EU's indominatable digital champion, Neelie Kroes). The announcement coincides with the beginning of another initiative, Global Legislative Openness Week, which will involve global activities annd "events hosted by the Legislative Openness Working Group of the Open Government Partnership and members of the parliamentary openness community." A full calendar of events is here. Read more

Nouveau For Linux 3.18 Gains DP Audio, More Re-Clocking

Ben Skeggs sent in his Nouveau DRM driver changes for the drm-next tree of open-source NVIDIA driver improvements that will land in Linux 3.18. With the DRM merge window now closing earlier in the cycle, David Airlie is cutting off new features for the next kernel merge window from landing into drm-next after -rc5 of the current kernel. Thus, this week is the cut-off for new DRM driver functionality aiming for Linux 3.18 with Linux 3.17-rc5 having been released. As such, Ben Skeggs sent in his big batch of Nouveau DRM improvements.

With Android One, Google puts itself firmly back in the OS' driving seat

Under Android One, Google has developed its reference hardware designs — meaning OEMs no longer have to develop and test their own smartphones; they just pick up Google's ready-to-wear versions and get manufacturing. Google already has three local Indian smartphone makers signed up to do just that — Karbonn, Spice, and Micromax — all soon be be selling Google-designed, Android One-powered devices for around $100. Android One uses a stock version of Android, as seen on its Nexus products — meaning no UI customisation is possible — but Google has graciously offered to let OEMs and mobile operators add their own apps to handsets running the OS. The operators don't seem to mind the disintermediation much, and have teamed up with Google to launch Android One mobile plans to coincide with the launch of the new phones. Read more
