AMDKFD Driver Still Evolving For Open-Source HSA On Linux

Filed under
Graphics/Benchmarks
Linux

Earlier this month AMD published an open-source HSA Linux driver for exploiting the potential of their much-promoted Heterogeneous System Architecture. This driver, now known as the "AMDKFD" driver, is up to its second revision and continues being analyzed by developers on the mailing list.

The aforelinked article goes over all the basic AMD HSA Linux driver details while its the AMD-specific HSA driver that's being worked on the most and discussed. Version two of the "AMDKFD" driver came out on Thursday and lives under the DRM Radeon GPU driver as the "AMDKFD" to provide the "HSA kernel driver for AMD Radeon devices."

RadeonSI Gallium3D Now Supports GL4 Indirect Drawing Too

Filed under
Graphics/Benchmarks

Just a very short time after Nouveau added support for OpenGL 4 indirect drawing, AMD developers have now added support for the related OpenGL 4.x extensions to the RadeonSI Gallium3D driver.

The extensions newly supported by the RadeonSI Gallium3D code in mainline Git is OpenGL 4.0's GL_ARB_draw_indirect and OpenGL 4.3's GL_ARB_multi_draw_indirect. This work is just about the RadeonSI Gallium3D driver and not R600g. These extensions are also enabled for the Gallium3D Softpipe and LLVMpipe fallback drivers too, besides the Nouveau NVC0 and Intel i965 support too.

CentOS 6.5 vs. CentOS 7.0 NAS Performance Comparison

Filed under
Graphics/Benchmarks
Red Hat

RedHat Enterprise Linux is an enterprise-grade Linux distribution, which is frequently used in corporate data centers as an operating system for NAS storage devices. From the performance point of view, the new Linux kernel and the new default file system may have a significant impact on a NAS storage device and therefore it is very important to understand how the newly released RedHat Enterprise Linux version 7.0 compares to the last stable version 6.5.

NVIDIA Contributes Re-Clocking Code To Nouveau For The GK20A

Filed under
Graphics/Benchmarks
Hardware

One of the biggest challenges with the Nouveau open-source graphics driver for NVIDIA graphics hardware in recent times has been with regard to GPU / video memory re-clocking. As a minor step forward, NVIDIA has contributed re-clocking patches for the GK20A graphics processor.

Re-clocking has long been a big challenge for the Nouveau driver to obtain maximum graphics performance while also maintaining optimal performance-per-Watt and being efficient while idling. With the Linux 3.16 kernel for select generations of GPUs is faster performance but it can be buggy while now today for Tegra K1 owners NVIDIA has come to the table with re-clocking code for the "GK20A" GPU found within this high-end NVIDIA ARM SoC.

Preview: Benchmarking CentOS 7.0 & Scientific Linux 7.0

Filed under
Graphics/Benchmarks
Red Hat

In this article just for putting the initial CentOS/SL results into some perspective, I have some initial data from a single Intel Core i7 system running these new releases plus Fedora and Ubuntu Linux. Just as some initial metrics to get started with our benchmarking, from an Intel Core i7 4770K system with 8GB of RAM, 150GB Western Digital VelociRaptor HDD, and Intel HD Graphics 4600, I tested the four Linux distributions. The hardware and its settings were maintained the same during testing.

Originally for this first article I also hoped to test Scientific Linux / CentOS 6.5 too, but after doing the 7.0 tests and trying to boot the 6.5 releases, there was a kernel error preventing the testing from being realized (on initial boot was the i915 DRM error about detecting more than eight display outputs; when booting without DRM/KMS mode-setting support, there would be an agpgart error.) The i915 issue is corrected on future kernel revisions but for this system it was preventing the 6.5 releases from running nicely. From an older, more workstation focused system I will be running the new vs. old CentOS/SL releases.

NVIDIA 340.24 Linux Driver Has G-SYNC Support, FXAA Control

Filed under
Graphics/Benchmarks
Linux

Succeeding last month's NVIDIA 340.17 Linux driver beta is now the first official release in the 340.xx driver series for Linux / Solaris / BSD. The NVIDIA 340.24 driver was released this morning with new features but is heavier on the fixing side.

The main feature to the NVIDIA 340.24 driver (and carried over from the 340.17 driver) is initial support on Linux for G-SYNC monitors. The proprietary NVIDIA Linux driver now has support for dealing with G-SYNC (NVIDIA's variable refresh-rate technology similar in nature to AMD FreeSync and VESA Adaptive-Sync -- the support came just months after we reported NVIDIA was working on G-SYNC Linux support.

Linux 3.16 File-System Tests On A Hard Drive

Filed under
Graphics/Benchmarks

In complementing the earlier Linux 3.16 file-system tests on an SSD (and the later Btrfs testing), here are benchmarks of EXT4, XFS, and Btrfs from the Linux 3.15 and 3.16 kernels being compared from a traditional rotating hard drive.

As has become common practice at Phoronix, for each new development kernel we end up benchmarking the most commonly used, mainline Linux file-systems on a hard drive and solid state drive. With the SSD results out there in the aforelinked articles, in this article are results using a high-performance Western Digital HDD from a Core i7 Haswell system running Ubuntu and comparing the mainline stable Linux 3.15 kernel against a daily snapshot of Linux 3.16 from this week.

X.Org Server 1.16 Delayed To Let In Non-PCI Graphics Support

Filed under
Graphics/Benchmarks
Server

X.Org Server 1.16 has been delayed. However, it's not been delayed like in some of the more notorious past releases due to outstanding bugs, etc, but over letting in a late feature to this latest revision of the X11 server.

There was a lot of developer interest and pressure to let non-PCI device support get merged for the 1.16 stable release. This non-PCI support is needed for allowing the NVIDIA Tegra (open-source) graphics driver to work properly in an easy manner since it's not exposed as a PCI VGA device. Thierry Reding at NVIDIA along with support from other developers worked out adding this non-PCI graphics support on the X.Org Server side.

Gaming

The Deepin Desktop Environment is written using Google's Go language and makes use of heavy HTML5. DDE also uses Compiz as its compositing window manager. As in the past some desktop environments / window managers have impaired the full-screen Linux gaming performance, I ran some simple Linux gaming benchmarks on Sunday to see if the Deepin 2014 performance differed at all from upstream Ubuntu 14.04 LTS. Ubuntu 14.04 was tested with the stock Unity 7.2 desktop using Compiz, GNOME Shell 3.10.4, and Xfce 4.10 all from the stock Trusty Tahr archive.

NVIDIA Releases 331.89 Long-Lived Linux Driver

Filed under
Graphics/Benchmarks

NVIDIA has today released ther 331.89 Linux, Solaris, and FreeBSD graphics drivers within their long-lived 331.xx graphics driver branch.

The NVIDIA 331.89 graphics driver for Linux (and Solaris/FreeBSD) includes support for the GeForce GT 730 graphics card, support for X.Org Server 1.16, and a variety of bug-fixes. The bug-fixes are great and the GeForce GT 730 hardware enablement is also great while nearly all NVIDIA 331 graphics driver users will be able to appreciate the X.Org Server 1.16 support considering the xorg-server update isn't even scheduled to be released until next month, will make it into the H2'2014 Linux distribution updates, and chances are the AMD Catalyst driver won't even support the new server for some months based upon their historical turnaround times.

For some brief benchmarking during Independence Day in the US, I ran some tests comparing Ubuntu 14.04 LTS stable against a fresh development snapshot of Ubuntu 14.10.

Over Ubuntu 14.04, the Ubuntu 14.10 "Utopic Unicorn" in its current development state has the Linux 3.15 kernel (but will end up using Linux 3.16), Unity 7.3.0, Mesa 10.2 (10.3 should make it in time for Ubuntu 14.10), and GCC 4.8.3 (while GCC 4.9 should make it for 14.10).

Testing Btrfs On The Linux 3.16 Kernel

Filed under
Graphics/Benchmarks

When running my initial Linux 3.16 file-system tests on an SSD I had to skip over Btrfs due to initial problems with the experimental kernel code. Fortunately, Btrfs has been fixed-up in Linux 3.16 and can now serve for some benchmarking.

As F2FS, XFS, and EXT4 were already tested on a solid-state drive using Linux 3.16 Git, in this article I'm just testing Btrfs when using the Linux 3.15 stable kernel against the Linux 3.16 Git kernel from 2 July. This Btrfs testing happened from an ASUS UX32VDA Core i7 Ivy Bridge ultrabook with 128GB SanDisk SD5SF212 SSD. A daily snapshot of Ubuntu 14.10 was used for testing while the kernel snapshots were obtained from the Ubuntu Mainline Kernel PPA for easy reproducibility.

Preview: Fedora 20 Updated vs. Fedora 21 Rawhide Benchmarks

Filed under
Graphics/Benchmarks

While Fedora 21 remains under heavy development, for some new benchmarks to get July started I ran some tests of a stock Fedora 20 installation versus Fedora 20 with all stable updates versus Fedora 21 in its "Rawhide" state.

These tests are just to look at the Fedora 20 updated performance and to offer a glimpse towards Fedora 21. Fedora 21 won't be released until at least October so take the results as you wish. Additionally, Fedora Rawhide tends to enable a lot of debug/development code that can potentially slow down the system compared to Fedora in its release form. Nevertheless, these latest Fedora Linux benchmarks should be interesting in their own right.
