Since writing about the features of the Catalyst 14.6 Beta earlier today, the x86/x86_64 proprietary Linux driver has surfaced on a third-party web-site for those wishing to try out this latest AMD Linux graphics driver.
As explained this morning, Catalyst 14.6 Beta for Linux comes with official Ubuntu 14.04 LTS support, driver installer improvements, and various bug-fixes as the primary changes.
The first beta release of the Catalyst 14.6 proprietary Linux graphics driver will soon be available.
The Catalyst 14.6 Linux driver will introduce official Ubuntu 14.04 LTS support, install improvements by having better defaults and prompting to auto-install the packages generated by the driver, and various bug-fixes are landing.
After last week carrying out separate NVIDIA Windows vs. Linux OpenGL benchmarks and similar AMD Radeon Windows 8.1 vs. Ubuntu 14.04 tests, today we are pitting the GeForce and Radeon graphics cards against each other on Ubuntu Linux with the very latest drivers to see how their performance compares now head-on. With this testing we have some Steam games plus are also monitoring the power consumption, performance-per-Watt, and GPU thermal metrics.
Mesa is up to 1.4 million lines of code and has already seen almost 2,500 Git commits so far this year.
With Mesa 10.2 planned for release this week, this morning I ran GitStats on the Mesa Git code to look at the latest development trends for this open-source OpenGL library with the various mainline hardware drivers from Intel's classic DRI driver to the Gallium3D architecture and its many drivers like Radeon, Nouveau, and Freedreno.
The success of the SteamOS Linux distribution is revealing that AMD is going to get a kicking in the future and it just cannot see it.
For a decade it would have been fair enough for a consumer chipmaker to ignore Linux. All those who said
While 2014 is not the year that Linux will take control of the desktop either, the writing is appearing on the wall and it is silly for AMD to ignore it.
SteamOS users are suffering from a lack of proper AMD driver support and it is taking ages for anyone to get games on the OS running.
Following the benchmarks I posted this morning showing Intel Haswell graphics having some OpenGL slowdowns with the newer Mesa graphics driver code, I tested a sharply different Haswell system to see if the performance differential was also to be found on this Intel ultrabook with Iris Graphics 5100...
For those curious about the impact of running Intel "Haswell" HD Graphics 4600 on Ubuntu 14.04 LTS and then pulling in the latest Mesa 10.3-devel code followed by the Linux 3.15 kernel, it's not entirely a happy story if you are looking to maximize your Intel Linux graphics performance capabilities.
Having done a clean install of Ubuntu 14.04 LTS this week on a Core i7 4770K system I figured I would do the usual graphics driver performance update of comparing Ubuntu 14.04 out-of-the-box (Linux 3.13 + Mesa 10.1) against pulling in the latest Oibaf PPA packages to have xf86-video-intel 2.99.911 DDX and the Mesa 10.3-devel Git master code (a big leap from Mesa 10.1.0). Lastly, with the updated Intel user-space graphics drivers I then updated kernel-space by moving to the Linux 3.15 kernel via the Ubuntu Mainline Kernel PPA.
Huang's diligence paid off and at a time when other kids were focused on getting a high score on Asteroids, he was reading DIY electronics guides in Byte magazine and building add-on cards for the Apple II.
Today Huang, who goes by the nickname 'bunnie', has just drummed up more than $700,000 through the website Crowd Supply for his project to build an open source computer called Novena.
Huang is setting out to create a machine whose inner workings are as transparent as the computer that three decades ago sparked his lifelong interest in creating hardware.
Vendors like MIPS owner Imagination, Broadcom and Qualcomm are looking to drive MIPS adoption with the Prpl Foundation.
Two years ago Amit Rohatgi helped bring Google's Android to MIPS processors. Today he wants to bring the rest of open-source software to the architecture.
Rohatgi's latest effort is a consortium called prpl (pronounced purple). (The name was suggested by Rohatgi's wife, a graphics designer, and refers to the logo color of Imagination Technologies, the company that bought MIPS in February 2013.) Its 10 founders include Broadcom, Cavium, Ikanos, Lantiq, PMC-Sierra, Qualcomm, and a handful of smaller companies that use or make MIPS-based chips.
Samsung Electronics is considering joining Qualcomm’s AllJoyn project, but there is some debate over the possibility as Samsung is currently developing its own Internet of Things platform, industry watchers said Wednesday.
NVIDIA GRID Workspace is a virtualized desktop environment from NVIDIA that offers “cloud-delivered graphics acceleration for enterprise applications.” The NVIDIA GRID Windows client was released yesterday for a limited time only. Linux and Mac OS X are said to be in the works, so while I’m waiting for the Linux client to be released, I decided to test-drive the Windows client on an installation of Windows 7 Pro in a (VirtualBox) virtual environment.
Yes, that’s running a virtual desktop on a virtual desktop. I didn’t know how responsive the system will be, especially when I allocated only 1.3 GB of RAM to Windows 7 and it did not have hardware acceleration enabled.
AMD’s “Bald Eagle” R-Series processors offer four 3.6GHz “Steamroller” cores with Heterogeneous System Architecture support, plus Mentor Embedded Linux.
AMD has a dual-platform strategy for embedded: G-Series on the low end and R-Series on the high end. Now, the chipmaker has launched a second generation of AMD Embedded R-series processors in both CPU and APU (accelerated processing unit) variants, with the latter offering integrated, rather than optional discrete AMD Radeon graphics. AMD tipped its Bald Eagle R-Series processors last September, and has launched sales for five new variants. The new R-Series CPUs are designed for gaming machines, digital signage, medical imaging, industrial control and automation, and communications and networking infrastructure, says AMD.
After this week having carried out benchmarks showing Intel's Windows 8.1 OpenGL driver is outperforming their open-source Linux driver but NVIDIA's driver on Ubuntu Linux is commonly faster than Windows 8.1, the time has come to benchmark several different AMD Radeon graphics cards under Ubuntu 14.04 LTS and Windows 8.1 Pro x64 with all available updates and each OS using the latest Catalyst 14.4 driver.
The Linux DisplayPort MST code has been working for nearly one month and it's now undergoing further review by other upstream Linux DRM developers. Airlie wrote in a new mailing list post tonight, "So this set is pretty close to what I think we should be merging initially, Since the last set, it makes fbcon and suspend/resume work a lot better, I've also fixed a couple of bugs in -intel that make things work a lot better. I've bashed on this a bit using kms-flip from intel-gpu-tools, hacked to add 3 monitor support. It still generates a fair few i915 state checker backtraces, and some of them are fairly hard to work out, it might be we should just tone down the state checker for encoders/connectors with no actual hw backing them."
Wayland 1.5 features a new internal event queue for Wayland display events, which allows for the client library to dispatch delete and error events immediately. On the build front, Wayland now uses non-recursive Makefiles.
As usual, the Weston compositor changes tend to be more interesting these days and includes more work on XDG-Shell, the Weston input stack is now split out into libinput, there's support for the new XWayland Server to be found in this summer's release of X.Org Server 1.16, the full-screen shell was added, an animate window closing event, support for different color depths on different outputs, and other changes.
The NVIDIA 331.79 Linux driver was just announced by NVIDIA's Aaron Plattner and it includes fixes for: a crash with the nvidia-installer, a module signing issue with the NVIDIA Unified Memory kernel module, a blank screen/flickering issue when rotating displays with Base Mosaic, a bug that caused errors for big-endian X11 clients with certain RandR requests, a bug that corrupted certain software rendering, and a bug that caused issues with EDID version 1.3 or older for systems using DisplayPort in certain configurations.
There's been many requests to run some new OpenGL and 2D performance benchmarks under different Linux desktop environments. With the imminent release of Linux Mint 17 and it shipping the latest version of the increasingly-popular Cinnamon Desktop Environment, here's a six-way desktop performance comparison using Intel graphics on Linux Mint 17.
The AST DRM driver has seen a few improvements with code that's landed today in drm-next for ultimately making it into the Linux 3.16 kernel.
The ASpeed Technologies DRM driver (AST) just features basic display support for some chips commonly found in servers. The improvements that will land for the next kernel cycle include.
The latest Linux graphics testing under the microscope at Phoronix is comparing the Ubuntu 14.04 LTS vs. Windows 8.1 performance with all available updates. Results from Intel, NVIDIA, and AMD hardware is coming up next week while today is a bit of a preview of the AMD numbers when using a Radeon R9 290 "Hawaii" graphics card. While the open-source AMD Hawaii support remains broken, with the Catalyst 14.4 driver on each operating system, the Linux Catalyst driver with the R9 290 graphics card can outperform Windows 8.1 Pro with some OpenGL games and benchmarks.
