In the discussion about the latest AMD R600g driver improvements by Marek Olšák, the prolific independent contributor shares some of his personal views on the open-source graphics driver itself.
Marek Olšák has continued with his passionate development contributions to the R600 Gallium3D driver, being one of the few independent contributors continuing to make heavy contributions to this open-source AMD Linux graphics driver.
The R600g patches for reworking the atom state emission ordering have landed, after having to infer the ordering sequence from the Catalyst binary blob command stream.
When talking about the state of open-source Radeon driver features last weekend, one of the areas to first be criticized within the forums was the improper power management of the open-source AMD Linux graphics driver.
While the Catalyst Linux graphics driver was overhauled five years ago, not everyone is satisfied with the closed-source AMD Radeon Linux graphics driver. Here's some interesting comments by a prominent Linux developer and his less than stellar Catalyst experience.
It was five years ago today that AMD's open-source strategy for Linux graphics driver support was publicly unveiled.
Today marks five years since the revolutionary AMD Catalyst Linux graphics driver was announced to the world by Phoronix. While the driver still had a lot of work ahead, it was September 2007 that brought the brand new Catalyst Linux driver that shared more code with the Catalyst Windows driver and ushered in a new era for AMD with providing same-day Linux driver support, performance improvements, and new functionality to match the Windows driver.
For those curious about the state of various features for the range of ATI/AMD Radeon GPUs on the open-source Linux graphics driver stack, the feature Wiki continues to be maintained.
For those that enjoyed seeing the RadeonSI Gallium3D driver TODO list but aren't able to contribute due to not owning any Radeon HD 7000 series hardware, there also exists an R600 Gallium3D driver TODO list that is in need of some attention.
Marek Olšák has continued with his "R600g" driver hacking. The latest patch-set coming from this prolific independent contributor to Mesa allows for anti-aliasing and transform feedback for Radeon HD 6900 "Cayman" GPUs.
The AMD Radeon HD 7000 "Southern Islands" graphics cards have been on the market for about nine months now, and while there is AMD Catalyst Windows/Linux driver support, the open-source driver support still leaves a lot to be desired. If you are a developer looking to dive into open-source graphics drivers, a comprehensive TODO list has been written.
KWin, KDE's compositing window manager, will better play with the AMD Catalyst binary blob in the KDE 4.10 release by enabling direct rendering and the OpenGL 2.x back-end for those using the latest Catalyst driver.
Thanks to the great work of Marek Olšák, the prolific independent contributor to Mesa/Gallium3D that is still at university, AMD Radeon HD 2000/3000 "R600" hardware now has MSAA (anti-aliasing) support from the open-source Linux graphics driver.
As expected, with Marek Olšák requesting a delay in branching Mesa 9.0 so that he can land more features, support for multi-sample anti-aliasing (MSAA) for more ATI/AMD Radeon hardware has landed plus there's improved anti-aliasing support for currently-supported GPUs.
Last week we heard news that NVIDIA is at least evaluating support for their binary graphics driver with Wayland, but on the AMD Catalyst binary driver side it doesn't look like they will be supporting the next-generation Linux display architecture "anytime soon", according to a reliable source.
The Radeon DRM driver already has a few features in its development branch that is being prepared for merging into the future Linux 3.7 kernel.
A Catalyst 12.8 proprietary driver release is now available for Linux, but it doesn't pack much in the way of changes.
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.
