While the Intel 830GM and 845G chipsets were first introduced more than one decade ago, their graphics driver support has been botched for much of the time. As of today though, Intel Linux driver developers think they have taken care of the longstanding stability issues with this now ancient hardware.
In prior years there was the i965g driver that was developed independent of Intel and was targeting an open-source Gallium3D driver for Intel's newer chipsets. But unlike the i915g that was developed similar in nature, the i965g driver really never reached a working state and was ultimately removed. There is now a brand new "i965g" Gallium3D driver that is targeting support for Intel Sandy Bridge "Gen6" graphics and newer.
ETC2, the new royalty-free texture compression method that's required by OpenGL ES 3.0, now has support within mainline Mesa. However, for now this ETC2 support is limited to the Intel DRI driver.
Intel should finally have Haswell graphics support on Linux in shape with the Linux 3.8 kernel after earlier admitting they screwed up, not all areas of the open-source GPU driver support are polished ahead of the big Haswell CPU launch in 2013.
Shortly after improving the HyperZ support in R300g, Marek Olšák has now enabled HyperZ support by default for ATI R500 (Radeon X1000 series) GPUs.
Chris Wilson has continued with the xf86-video-intel 2.20.x point releases.
The Intel DRM graphics driver in the Linux 3.8 kernel will feature a number of user-facing changes.
It's been announced this morning that Intel is acquiring ZiiLabs, the subsidiary of Creative Labs that previously was 3DLabs. Intel is gaining "certain engineering resources and assets" plus licensing rights to certain ZiiLabs patents and other technologies surrounding the GPU.
Linux kernel developers have created an Intel PowerClamp driver, which is an experiment with idle injection for Intel hardware to take advantage of power-efficient package-level C-states for power capping and passive thermal control. Separately, Intel RAPL (Running Average Power Limit) support is now exposed through TurboStat.
In addition to NVIDIA and AMD announcing new high-end server/workstation GPUs to coincide with this week's SuperComputing SC12 conference in Salt Lake City, Intel has announced new details and release information on their Xeon Phi co-processors.
Chris Wilson of Intel's Open-Source Technology Center continues releasing new xf86-video-intel 2.20.x point releases.
The Intel VA-API 1.0.19 driver was released on Thursday and it's a feature release with some exciting additions.
While AMD is letting go of their Linux staff responsible for new CPU enablement, there's no slowdown on the Intel side for future hardware enablement under Linux. New Haswell Linux patches were published yesterday, which also reveal a few more details about the video playback improvements to be found on these Intel processors to be introduced in 2013.
If you liked yesterday's post by Daniel Vetter of Intel's Open-Source Technology Center that covered going over the Graphics Execution Manager for memory management, today he's around with a second part that details command submission handling for the Intel open-source Linux driver.
For those not yet familiar with GEM, the Graphics Execution Manager, that Intel's open-source Linux graphics driver uses for in-kernel memory management, here's a brief guide.
Intel Linux developers continue to work on atomic mode-setting and page-flipping support for their Linux DRM infrastructure.
Just minutes after writing about how Intel keeps releasing open-source Linux code for Haswell, their next-generation hardware for 2013, they ended up pushing out their initial video acceleration (VA-API) support code.
Intel continues to push out more open-source kernel code for enabling their next-generation Haswell processors to be properly supported under Linux.
Open-Source Intel developers have long been working towards a tear-free Linux desktop with proper vsync support. For Sandy Bridge and Ivy Bridge hardware there's still been some tearing issues, but they hope to soon finally have it solved.
While Intel is now forcing on S3TC to be advertised for their Mesa driver by default, the ETC2 texture compression scheme holds more hope and support for it within the Intel Mesa driver is also being worked on.
Two patches from Intel's Ian Romanick for their open-source Mesa DRI driver will now enable S3TC extensions always plus floating-point textures. These two features previously were not enabled by default out of patent fears.
After the change yesterday to now hide early Intel hardware support by default to fend off early driver issues for new graphics hardware -- such as mode-setting just outright failing to work -- Intel has commented a bit more on the driver support for the forthcoming "Haswell" hardware.
While Intel is quick to work on enabling future hardware within their open-source graphics driver stack for Linux, the early support is often buggy and problematic on the early code before the hardware is released. Intel now intends to conceal this early hardware support -- for Valley View and Haswell right now -- behind a run-time variable for toggling the support.
Chris Wilson released the xf86-video-intel 2.20.10 DDX driver this weekend and it fixes up a number of core graphics driver bugs, including issues for older generations of Intel integrated graphics hardware.
Following this morning's article about running GStreamer over VA-API on Wayland, Gwenole Beauchesne of Intel wrote in about some new VA-API package releases.
There's a bit of a spat that started between Intel and Samsung developers working on the Tizen operating system.
Aside from knowing about the Radeon DRM driver changes queued up for the Linux 3.7 kernel, there's also lots of good changes piling up for the Intel DRM graphics driver with this next kernel release.
Intel SMAP support has landed in the mainline Linux kernel, which is a Supervisor Mode Access Prevention found on newer Intel CPUs.
The Intel i965 Mesa DRI driver can now handle register spilling.
Chris Wilson has released yet another xf86-video-intel 2.20.x driver. This time around, the 2.20.9 point release brings back X-Video Motion Compensation (XvMC) and also fixes a critical bug.
