AMD RadeonSI Gallium3D Performance For 4K Linux Gaming

Filed under
Graphics/Benchmarks
Gaming

While we routinely carry out Ultra HD (4K) Linux graphics/gaming benchmarks at Phoronix, it's generally been conducted with the proprietary NVIDIA and AMD graphics drivers since the open-source drivers traditionally have had a challenge on performance even at 1080p. However, thanks to the maturing open-source Radeon driver stack, it's possible with higher-end AMD graphics processors with the latest open-source Linux driver code to begin running at the 4K UHD resolution of 3840 x 2160.

Ubuntu

Two months after the release of X.Org Server 1.16, AMD finally has readied a Catalyst Linux driver update that is compatible with the latest xorg-server ABI. This driver is being sent into the Ubuntu 14.10 archive and thus allowing the entire Linux graphics stack in Ubuntu 14.10 to finally be updated.

Sent into utopic-proposed on Tuesday was a new fglrx driver version. The new fglrx driver is labeled 14.201-0ubuntu1 as a new upstream Catalyst/fglrx release. While there is no full change-log for this driver, the Ubuntu change-log notes that the driver is compatible with xorg-video-abi-18 as the Application Binary Interface requirements for X.Org Server 1.16.

GCC 4.9 vs. LLVM Clang 3.5 On Intel's Haswell-E Platform Under Linux

Filed under
Graphics/Benchmarks

With my Intel Core i7 5960X Haswell-E Linux review out there, one of the quick to be requested extra tests is benchmarking the i7-5960X 16-thread processor with LLVM/Clang against GCC. Here's some initial data comparing the compilers for this $1000+ processor.

From the Core i7 5960X system with Gigabyte X99-UD4-CF motherboard, 16GB DDR4 memory, and 128GB SSD, Ubuntu 14.10 was running on the system with its stock Linux 3.16 kernel. For this quick, one-page testing of the i7-5960X compilers I used the packaged GCC 4.9.1 amnd LLVM Clang 3.5.0 compilers found within the Ubuntu 14.10 package archive.

Nexus 5 2014 with Android Lion leaked in benchmark test

Graphics/Benchmarks

Is Android L going to be called Lion? We’ve no certainty of that and the following information should be taken with a grain of salt, but supposedly, Google might choose Lion as the identifier for the new Android OS. Lemon Meringue Pie and Lollipop might also be among the names Google is pondering upon, but we don’t know which is the one that will stick.
The Nexus 5 2014 was listed in the leak with a 5.2 inch Quad HD display, Snapdragon 805 clocked at 2.7 GHz, 3 GB RAM, 32 GB internal storage, a 12 MP rear and 2 MP front camera. So far, these are mildly impressing specs, the best feature of the Nexus 5 2014 being its Snapdragon 805 CPU. This device might also be the one we’ve been hyping about so much, dubbed Nexus 6, Shamu or even Nexus X, but it might as well be a wholly different device.

Drawing Web content with OpenGL (ES 3.0) instanced rendering

Filed under
Graphics/Benchmarks
GNOME

There is one important conclusion coming out from these experiments: The fact that a rasterizer is normally stateless makes it very inefficient to modify a single element in a scene.

By stateless I mean they do not keep semantic information about the elements being drawn. For example, lets say in one frame I draw a rectangle, and for the next frame I want to draw the same rectangle somewhere else on the canvas. You already have a batch with all the elements of the scene, happily stored in a vertex buffer object on GPU memory, and the rectangle in question is there somewhere. If you could keep the offset where that rectangle is in the batch, you could modify its attributes without having to drop and re-submit the whole batch.

9-Way File-System Comparison With A SSD On The Linux 3.17 Kernel

Filed under
Graphics/Benchmarks

Each file-system was tested with its stock mount options on the Linux 3.17 Git kernel. No kernel modifications were made to this system under test. The new AMD FX-8370 system was used for the Linux benchmarking system in this article. All of our disk / file-system tests are facilitated by the Phoronix Test Suite.

Woman force in Open Source: Xorg joins the Outreach Program for Women

OSS
Misc

The CTO of the United States of America is a woman, CEO of HP, Yahoo! and many tech giants are women – leading these companies towards future.

However when it comes to core technologies the number of women participants is quite low and disturbing. I am not aware of any leading open source project which was founded by a woman. So Gnome Foundation started a project called Outreach Program for Women (OPW) to increase the participation of women in free software.

More Wayland Improvements Hit Enlightenment E19

Filed under
Graphics/Benchmarks

One week after Enlightenment's E19 RC3 release, there's more improvements that have landed that will warrant another new release in the very near future.

Posted to the E19 release manager blog is The Septembering -- going over the latest changes so far this September. There's Covery-detected issues fixed, system tray improvements, and more Wayland improvements. The latest Wayland work includes pointer fixes and improved resolution detection.

E19 features the rewritten Wayland compositor that's working out great natively on Wayland without depending upon X11 or Weston for that matter. The E19 release is due out soon with a ton of notable changes.

ACPI, kernels and contracts with firmware

This ends up being a pain in the neck in the x86 world, but it could be much worse. Way back in 2008 I wrote something about why the Linux kernel reports itself to firmware as "Windows" but refuses to identify itself as Linux. The short version is that "Linux" doesn't actually identify the behaviour of the kernel in a meaningful way. "Linux" doesn't tell you whether the kernel can deal with buffers being passed when the spec says it should be a package. "Linux" doesn't tell you whether the OS knows how to deal with an HPET. "Linux" doesn't tell you whether the OS can reinitialise graphics hardware. Read more
