Intel P-State vs. CPUFreq Benchmarks On The i7-5960X

Filed under
Graphics/Benchmarks

Testing was done with the Intel Core i7 5960X at stock speeds. The Linux 3.17 Git kernel atop Ubuntu 14.10 was used for this round of testing. The Core i7 5960X has eight physical cores plus Hyper Threading, 3.0GHz base frequency, and 3.5GHz turbo frequency (that's the reported difference in the system information table due to P-State advertising the turbo frequency where as CPUFreq just reports the base frequency).

Graphics Driver Changes Coming In The Linux 3.18 Kernel

Filed under
Graphics/Benchmarks
Linux

While the Linux 3.17 kernel isn't being released for a few weeks, we already have a good idea for the DRM graphics driver improvements coming for the Linux 3.18 cycle.

Linux 3.17 has many new features, including many DRM graphics improvements, with Linux 3.18 there's of course more changes to get excited about; it's a never-ending cycle in improving Linux graphics drivers and the kernel stack as a whole. With Linux 3.18 though, it's going to be the first release where the drm-next merge window is closing early. Usually David Airlie, the DRM subsystem maintainer, allows new DRM graphics driver code to be introduced up until the start of the next kernel merge window, with that drm-next code-base then being sent in for mainline inclusion. Beginning with Linux 3.18, Airlie is planning to close the merge window of drm-next around the -rc5 state of the previous release. As a result, this week is likely the last that major new DRM graphics driver code has a chance to land for making the 3.18 window.

Linux

With X.Org Server 1.16 having landed in Ubuntu 14.10, it's time for some benchmarks comparing the 1.15 and 1.16 releases on Ubuntu while using the GLAMOR 2D acceleration library.

For some basic X.Org 2D benchmarks I tested a Radeon HD 7950 and R7 260X while running various Linux 2D desktop benchmarks on Ubuntu 14.10 with the Linux 3.16 kernel and Mesa 10.4-devel. In testing the two graphics cards, I was using X.Org Server 1.15.1 that was previously found in the Ubuntu Utopic archive and then switched to X.Org Server 1.16.0 with the rebuilt DDX driver packages too.

RadeonSI Gallium3D vs. Catalyst At 4K UHD On Linux

Filed under
Graphics/Benchmarks

The open-source driver stack tested was with the Linux 3.17 Git kernel while using the Oibaf PPA to upgrade to Mesa 10.4-devel for the latest RadeonSI and LLVM AMD GPU code. The closed-source driver was the fglrx 14.20.7 / OpenGL 4.4.12968 Catalyst release. When running the Catalyst binary blob we had to downgrade from Linux 3.17 to Linux 3.16 for kernel compatibility. All tests were done from the Intel Core i7 5960X system running Ubuntu 14.10.

New Code Starts Lining Up For X.Org Server 1.17

Filed under
Graphics/Benchmarks

X.Org Server 1.17 is planned for release at the start of 2015 and thus puts the closing of the merge window in the middle of October. While some xorg-server 1.17 code has already landed, more is on the way.

X.Org Server 1.17 will continue with refining the in-server GLAMOR code that was merged with 1.16 for 2D acceleration in a generic manner over OpenGL. X.Org Server 1.17 is also looking to integrate the universal KMS mode-setting DDX driver. Keith Packard on Monday also shared several other code branches he's looking at as material for the 1.17 release.

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

Filed under
Graphics/Benchmarks

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.

Intel Core i7 5960X CPU Core Scaling Under Linux

Filed under
Graphics/Benchmarks

With the Intel Core i7 5960X Haswell-E is an eight-core processor with Hyper Threading to yield sixteen logical threads, we're seeing how well this extreme Haswell processor really scales with modern open-source workloads as we benchmark the i7-5960X under Ubuntu Linux and see how the benchmarks scale with varying core counts.

NVIDIA Maxwell GPU Support On Nouveau Still Requires More Work

Filed under
Graphics/Benchmarks

While the Maxwell-based GTX 900 series graphics cards are rumored to be launching in the weeks ahead, the GTX 750 Maxwell graphics cards on the open-source "Nouveau" Linux driver still need some more work before they'll play nicely when not using NVIDIA's proprietary Linux driver.

For NVIDIA Maxwell support within the open-source driver there's basic support within recent Linux kernel releases, the user-space code for Maxwell has landed within Nouveau's NVC0 Gallium3D driver, and there's xf86-video-nouveau support using GLAMOR. With the GLAMOR-required acceleration for Maxwell, the Nouveau DDX depends upon the built-in GLAMOR of X.Org Server 1.16 and newer (rather than the earlier independent GLAMOR acceleration library). With Ubuntu 14.10 now having X.Org Server 1.16 and is running the Linux 3.16 kernel (though with my tests for this Maxwell trial I already switched to Linux 3.17 Git), I pulled in the latest Mesa 10.4-devel packages and other updated components via the Oibaf PPA On Ubuntu 14.10.

RadeonSI Gallium3D-Nine Can Beat AMD Catalyst With Some Wine Tests

Filed under
Graphics/Benchmarks

The out-of-tree Direct3D 9.0 state tracker for Mesa's Gallium3D continues to show much potential for allowing Wine-based games to better perform on Linux with the open-source Gallium3D drivers.

There's a chance of this Direct3D 9 support being added to Mesa but Wine developers still appear uninterested in supporting this state tracker since it only covers Linux users, which itself is a subset of all Wine users with the program working on other programs too, and for the Linux support is bound just to those using the open-source Radeon and Nouveau Gallium3D drivers. For those going through the process of setting up "Gallium3D-Nine" and patching Wine, the D3D9 performance improvements tend to be dramatic over Wine's Direct3D-to-OpenGL translation layer.

Nouveau Lands A OpenGL 4.3 Feature & Fixes MPEG4 Video Decoding

Filed under
Graphics/Benchmarks

As explained by the OpenGL.org registry, "This extension allows a texture's data store to be 'viewed' in multiple ways, either reinterpreting the data format/type as a different format/type with the same element size, or by clamping the mipmap level range or array slice range. The goals of this extension are to avoid having these alternate views become shared mutable containers of shared mutable objects, and to add the views to the API in a minimally invasive way."

OpenStack Juno is out, Debian (and Ubuntu Trusty ports) packages ready

This is just a quick announce: Debian packages for Juno are out. In fact, they were ready the day of the release, on the 16th of October. I uploaded it all (to Experimental) the same day, literally a few hours after the final released was git tagged. But I had no time to announce it. This week-end, I took the time to do an Ubuntu Trusty port, which I also publish (it’s just a mater of rebuilding all, and it should work out of the box). Here are the backports repositories. For Wheezy: deb http://archive.gplhost.com/debian juno-backports main deb http://archive.gplhost.com/debian juno main For trusty: deb http://archive.gplhost.com/debian trusty-juno-backports main Read more

Video: Systemd the Core OS (no coughing)

There has been so much negative stuff about systemd on teh Interwebs lately. It is so sad. Quite a few distros picked systemd because they liked a lot of the features it has. Why do the people who like systemd actually like it? Sure, if you look hard enough, you can find those answers... but I remembered a video where the man himself explains it. Read more

GParted 0.20 also has GRUB2 restoration steps added to the help manual plus various translation updates. Read more

Ubuntu Touch RTM Update Is Out, Has Better Performance and Beautiful New Indicators

Ubuntu developers had some minor problems in the week before with all sorts of bugs that were popping out. They postponed the release of a new update for the Ubuntu Touch RTM and, at one point, they even got everyone to focus on fixing the problems and nothing else. Now they have a new version out and progress really shows. Users who already have Ubuntu Touch on their phones might have noticed that the number of features added to the system have diminished drastically, but that's the way it should be. The system is getting closer to its final stages and there is little reason to add new options now. The current form of the OS is not very far from the official release, so only fixes remain to be made. Read more
