AMD has published their instruction set architecture (ISA) documentation for the "Southern Islands" graphics processors that are used by their Radeon HD 7000 series products.
Support within the DRM user-space library for handling PRIME import and export of GEM buffer objects has been committed for the open-source Radeon Linux graphics driver.
AMD quietly released an update to their preferred compiler, Open64, last week. The AMD Open64 4.5.2 compiler supports their next-generation "Piledriver" Fusion APUs.
AMD's Radeon HD 5000 "Evergreen" graphics processors can now support multi-sample anti-aliasing (MSAA) with the open-source Radeon Linux graphics driver.
Earlier this week the RadeonSI Gallium3D driver hit the glxgears milestone for handling AMD's latest-generation Radeon HD 7000 series graphics cards on an open-source OpenGL driver. There's still much work left, but it's moving bit by bit.
It turns out that minutes after writing AMD Open-Source S.I. Botched, Hope For The Future, a number of "RadeonSI" Gallium3D driver commits landed in mainline Mesa.
We're now going into eight months since the AMD Radeon HD 7000 series "Southern Islands" graphics cards first launched. In that time the Catalyst Linux support has been stable and fine, but the open-source driver support is still unusable.
For those that didn't notice, this week AMD released a new header that defines the AMD ACPI interface used for laptops, PowerXpress, and chipset-specific functionality.
After delivering development statistics on the Nouveau driver and the Intel driver, here's some numbers looking at the development pace of the xf86-video-ati X.Org driver for Radeon graphics cards.
AMD pushed a load of commits this morning into the mainline Mesa Git repository that provide a new state handling implementation for the Radeon HD 7000 series "RadeonSI" Gallium3D driver.
While the open-source ATI driver doesn't have some super fast 2D acceleration architecture equivalent to Intel's SNA or a developer making prolific contributions to the DDX, as of earlier this month the Radeon driver has support for GLAMOR.
While the AMD Linux graphics team is busy proposing an LLVM back-end staging area, the AMD CPU folks have begun work on the GCC compiler and preparing support for the next-generation Bobcat processors.
Tom Stellard of AMD has proposed a staging area for LLVM back-ends, similar to the staging area of the Linux kernel.
Following yesterday's article about Radeon Gallium3D HyperZ support defeating open-source developers, Jerome Glisse has clarified the situation after trying to make this code work properly for more than a half-year.
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.
