Jerome Glisse has published a new patch to enable HyperZ support for the AMD Radeon (R600g) Gallium3D driver. While this patch could be pushed to Mesa, it's not being enabled by default as it's still causing some GPU lock-ups and developers can't seem to figure out the cause. Jerome is now moving onto other work.
It looks like, thanks in part to an existing shoddy EXA 2D acceleration implementation, that the GLAMOR-based Radeon acceleration support for xf86-video-ati may work out quite well.
There's now open-source GPU-based 2D hardware acceleration support for the AMD Radeon HD 7000 "Southern Islands" graphics cards using the xf86-video-ati driver.
A frequent Phoronix Forums contributor has created RadeonTop, a new utility for users of the open-source ATI/AMD Radeon Linux graphics driver.
It has been fourteen years since the ATI Rage 128 graphics cards were released, but some within the open-source community are still using this vintage graphics hardware and even advancing the ATI driver.
While owners of ATI/AMD Radeon HD 5000/6000/7000 series graphics cards have already had a Catalyst 12.6 Linux driver -- which many Linux users found to be disappointing -- today AMD has released a Catalyst 12.6 "Legacy" Linux driver for those using the older generations of Radeon hardware.
For any independent developers that have been wanting to explore ways to contribute to the open-source Radeon driver but have been intimidated by the lack of documentation within the code, the situation is beginning to improve.
David Airlie announced the xf86-video-ati 6.14.6 DDX driver release today, which will be the final open-source ATI driver release that supports user-space mode-setting (UMS). Going forward, only Radeon kernel mode-setting (KMS) will be supported.
Following the changing of the Catalyst release schedule and dropping old hardware support, Catalyst 12.6 for Linux has been officially released. However, it's already disappointing some Linux binary driver users.
While Intel's Ivy Bridge processors are only two months old, there's already a feature-rich driver and the full programming documentation available. Meanwhile for the Radeon HD 7000 series from AMD that is now more than six months old, the open-source driver is still incomplete and the documentation is lacking.
David Airlie sent in some PCI Express 2.0 patches for the Linux kernel DRM this morning, which will hopefully allow supported Radeon graphics cards to run at PCI-E 2.0 speeds by default.
Last week there were XBMC developers that wrote a public message on Phoronix about AMD's problems with video playback acceleration using their Catalyst Linux driver. The developers called AMD out on their shortcomings and now today there's a response out of AMD.
In its battle against NVIDIA's Kepler, yesterday AMD released the AMD Radeon HD 7970 GHz graphics card. Here's some thoughts from a Linux perspective.
For those intrigued by the article written by XBMC developers after being frustrated by AMD's Catalyst Linux driver, here's a look at some of the other options for GPU-based video acceleration under Linux.
In the discussion last night about AMD not having any plans to suspend their proprietary Linux driver, John Bridgman of AMD shared some interesting information about AMD planning to provide a full execution stack in open-source form.
Since AMD's decision to discontinue HD 2000/3000/4000 series support from the Catalyst driver plus other changes that upset some hardware owners, there's been some rumors that AMD may be discontinuing development of the Catalyst Linux driver and focus solely upon the open-source AMD Linux driver.
The R600 Gallium3D driver is beginning to enable Stream-Out support by default for a greater selection of the Radeon graphics processors.
The open-source Radeon DRM/KMS driver in the mainline kernel beginning with the Linux 3.5 release will finally provide support for HDMI audio on the Radeon HD 6000 "Northern Islands" graphics cards.
AMD developers are planning to remove user-space mode-setting (UMS) support from the open-source Radeon graphics driver.
AMD will be placing an ARM Cortex-A5 on future-generation Fusion APUs as what initially they are saying is for hardware-based security measures via ARM TrustZone Technology.
The R600g LLVM shader compiler back-end that's primarily intended for the Radeon Gallium3D compute support is now working a bit better for graphics support compared to when it was first committed.
The xf86-video-ati 6.14.5 driver was released today with several changes.
Compute (OpenCL) support for the AMD Radeon HD 6900 "Cayman" graphics cards has now landed in Mesa Git master.
While patches have been around for more than one year to support Hierarchical Z on the ATI/AMD R600 open-source driver, the Gallium3D support still hasn't been merged.
Fear not for all of those who have been very angry over AMD dropping the Radeon HD 2000/3000/4000 support in the same release as providing X.Org Server 1.12 support, word on the streets of Toronto is that their legacy driver branch does have support for this latest xorg-server release.
There were more OpenCL/compute-related commits to Mesa Git master on Friday afternoon. The main item is that the Radeon HD 5000 series has its compute support hooked-up.
Hidden away within the new Catalyst 12.6 Linux driver are 2D acceleration improvements. These improvements aren't visible by default but there's a special command to activate this "ShadowPrimary" support.
While AMD is changing their Catalyst driver program and there wasn't any Catalyst 12.5 release, there is a public beta of Catalyst 12.6 for Linux.
Word is breaking today on the Windows-focused web-sites that AMD's Catalyst driver program has fundamentally changed. How does this impact Linux Catalyst users? Unfortunately, it will likely prove to be in a bad way.
A story run on Phoronix yesterday was AMD admitting it has Linux problems and are looking to improve the situation. In large part it comes down to improving OpenCL on Linux with the Catalyst driver, but how does the OpenCL Linux performance stand today? Here's some benchmarks to answer that question.
