While AMD's Radeon R9 290 "Hawaii" graphics cards have been out on the market for more than a half-year, the open-source driver support still isn't working quite right when it comes to having GPU hardware acceleration.
Just under one month ago AMD released their AM1 APUs that resurrected the Sempron and Athlon branding for these low-end APUs packing up to four "Jaguar" CPU cores with Radeon R3 Graphics.
After getting the small Radeon DRM changes queued for Linux 3.15, AMD developers have gone ahead and merged their open-source AMD Mullins graphics driver support into the DRM library (libdrm), xf86-video-ati DDX, and Mesa.
AMD has a new Radeon DRM kernel driver patch pending that is able to offer Linux gaming performance improvements by improving the video memory bandwidth performance by the open-source graphics driver.
Another Radeon DRM pull request has been submitted for the Linux 3.15 kernel. While this Git pull request is mostly delivering fixes, it also tries to add the AMD Mullins APU support.
AMD has started rolling out their open-source Linux graphics driver support code for their recently announced Mullins and Beema APUs.
AMD has now revealed their newest APUs, codenamed "Beema" and "Mullins" while their Linux fate remains unclear.
The Linux Foundation will be announcing tomorrow that AMD and Mentor Graphics are partnering up with the embedded Yocto Linux project as advisory members.
After yesterday's testing of the GeForce 700 vs. Radeon Rx 200 Series With The Latest Linux Drivers test results were made available, the official Catalyst 14.4 Linux graphics driver was offered up to the public.
AMD's R600 Gallium3D driver that supports the Radeon HD 2000 through HD 6000 series graphics cards received a number of bug-fixes on Thursday.
AMD has kicked off a new week by releasing the Catalyst 14.4 release candidate for Linux. The big items with this release include R9 295X GPU support and full support for OpenGL 4.4.
For the many owners of "RV770" hardware out there with the once popular Radeon HD 4850 and HD 4870 graphics cards, AMD open-source developers are now proposing the dynamic power management (re-clocking) support be disabled by default to deal with open bugs.
AMD has decided to disable the LLVM compiler back-end by default within the R600 era Gallium3D graphics driver.
One of the more commonly occurring test requests at Phoronix lately has been about testing the open-source RadeonSI Gallium3D driver with the Radeon R9 290 "Hawaii" graphics cards. Sadly, there's a reason why the R9 290 hardware isn't tested on the open driver much under Linux.
At the beginning of the year Lauri Kasanen had issued a call for help via Phoronix for collecting Radeon video memory statistics as he was looking to optimize Radeon's vRAM handling for his university thesis. The code and thesis are now available.
This week AMD announced Athlon and Sempron APUs for their new AM1 platform that's comprised of socketed Kabinis with Radeon R3 (GCN-era) graphics. I delivered a launch-day Linux review of the AMD Athlon 5350 that is the highest-end AM1 APU currently offered while arriving today were the three other AM1 APUs: the Athlon 5150 and the Sempron 3850 and Sempron 2650 APUs.
Alex Deucher sent out a set of three patches today to update the microcode used by the AMD "Southern Islands" graphics processors.
As expected AMD unveiled the Radeon R9 295X graphics card this morning as the "world's fastest" for those with $1500 USD to spare.
A Radeon pull request for drm-next changes was sent in this morning for ultimately landing with the Linux 3.15 kernel.
AMD published two new OpenGL extensions today that the graphics giant has developed.
AMD and Mentor Graphics are teaming up to push open-source Linux development for embedded systems.
The two most interesting things I learned from AMD at the Game Developer's Conference last week were already covered on Phoronix: they're looking at a new Linux driver strategy with an open kernel driver for Catalyst and they are still evaluating the feasibility of Mantle on Linux, but there were also some other random things I learned from various AMD employees.
This week when at the Game Developer's Conference one of the topics that many Phoronix readers wanted me to find out more about was in regards to AMD's Mantle API being supported on Linux.
AMD has released a new Windows and Linux Catalyst proprietary graphics driver. The Catalyst 14.3 Beta for Linux doesn't advertise any new features, but it comes with some bug-fixes.
The xf86-video-ati DDX driver is now able to build against the in-tree GLAMOR code found within the X.Org Server 1.16 code-base.
Next week I will have out some interesting 2D benchmarks between Intel, Radeon, and Nouveau on the latest open-source drivers... Those results are very interesting but for some other interesting data to get out prior to the weekend is a EXA vs. GLAMOR 2D acceleration comparison for a Radeon HD 6870 graphics processor using the Linux 3.14 kernel and Mesa 10.2-devel.
AMD disabled tiling support by default recently for their newer GCN-based graphics cards on the open-source AMD Linux driver. Fortunately, that performance-boosting feature has been turned back on now for the latest Radeon graphics cards under the assumption you are running Mesa 10.1.
Older AMD (ATI) Radeon GPUs can now optionally use GLAMOR for 2D hardware acceleration in place of EXA when using the latest open-source graphics driver.
Fast color clear support has appeared in patch form for the RadeonSI Gallium3D driver as a move that should further benefit the open-source GPU driver's performance.
AMD has launched the Radeon R9 280 graphics card, but don't get too excited just yet.
