We now know that the Linux 3.11 kernel has a heck of a lot of AMD Radeon performance potential through the new dynamic power management (DPM) support in its DRM kernel driver, but how's the Nouveau performance? Here's some new benchmarks.
The patches published one month ago for Nouveau NVIDIA Fermi Compute Support on the open-source driver have now been committed to master for the next Mesa release. More importantly this is the base work for implementing NVIDIA performance counters.
While DRI2 PRIME has led to Optimus-like support for laptops with NVIDIA/Intel GPU combinations, one of the problems making this technology less beneficial is the lack of dynamic power management handling. What's the point of keeping one GPU fed with power when it's being unused and just lowering your battery life? Fortunately, a fix is ahead.
The Nouveau driver project is back to needing reverse-engineering data dumps on select NVIDIA graphics processors, which will help in some new re-clocking work. If you're just a Linux desktop user but wanting to help out this reverse-engineered NVIDIA driver project, providing MMIOtrace dumps is a great way to contribute.
The latest release of the open-source NVIDIA X.Org driver is now xf86-video-nouveau 1.0.9. Features of this new update include multi-screen reverse Optimus support and NVIDIA "NVF0" EXA and X-Video hardware acceleration.
For those looking to utilize hardware-based video acceleration for the reverse-engineered Nouveau driver on NVIDIA hardware, it's become a little bit easier setting up the system.
While Radeon DPM for Linux 3.11 is most of what Linux enthusiasts are talking about, the Nouveau changes in Linux 3.11 include support for H.264 and MPEG2 video decoding. The necessary user-space driver changes have now been made for supporting this accelerated video decode process from Nouveau Gallium3D.
As the latest for our early Ubuntu 13.10 Linux performance benchmarks, here's a brief comparison of the Nouveau Gallium3D vs. NVIDIA binary graphics driver performance from a NVIDIA GeForce "Fermi" graphics processor.
While the reverse-engineered Nouveau graphics driver has limited support for OpenCL/GPGPU support, it's been mainly capped to older "NV50" graphics cards. Published today though for review are patches for the Fermi "NVC0" hardware to expose compute support as well as the hardware performance counters.
The open-source reverse-engineered Nouveau driver now has 2D EXA acceleration and X-Video support for NVIDIA's "NVF0" or better known as the GK110 GPU found in the NVIDIA GeForce TITAN and GeForce GTX 780. Updates to the Nouveau DRM and Mesa Gallium3D driver have also arrived.
After talking about the big DRM changes heading for the Linux 3.11 kernel, the Nouveau DRM driver changes are finally known as they were pulled into the drm-next tree last night.
Patches published this week allow for H.264 and MPEG2 video decoding on certain NVIDIA GeForce GPUs via the VP2 PureVideo HD hardware engine.
It's been a while since the last Nouveau DDX driver update, but xf86-video-nouveau 1.0.8 was released this morning. This updated Nouveau X.Org driver comes with nearly two dozen changes.
Similar to yesterday's early Radeon DRM benchmarks from Linux 3.10, here's some initial OpenGL performance results for NVIDIA GeForce hardware when using the Nouveau DRM that's updated in the Linux 3.10 kernel.
The pull request for the open-source NVIDIA "Nouveau" Linux graphics driver for the Linux 3.10 kernel has been submitted to the DRM subsystem maintainer. While Nouveau has many shortcomings against the official NVIDIA Linux graphics driver, there isn't much to get excited about with this new kernel driver update.
The first NVIDIA Tegra DRM driver changes for the Linux 3.10 kernel are now known.
Initial patches are ready to provide support for OpenGL geometry shaders within the Nouveau NV50 Gallium3D driver.
The developers behind the reverse-engineered open-source Nouveau graphics driver for NVIDIA hardware are still hard at work on preparing new changes for introduction with the Linux 3.10 kernel.
There was a bit of Gallium3D Nouveau activity merged to master this morning.
Nouveau, the reverse-engineered open-source NVIDIA Linux graphics driver, is faster for some OpenGL games when running on the soon-to-be-released Linux 3.9 kernel.
Christoph Bumiller published a set of new Linux kernel DRM driver patches for Nouveau, which includes support for VRAM compression.
For starting off Friday's benchmarking at Phoronix are some numbers when looking at the Nouveau driver with Ubuntu 13.04 against NVIDIA's proprietary Linux graphics driver when both are controlling a Quadro GPU found on a ThinkPad laptop.
With the recent Intel Ivy Bridge graphics benchmarks and the newer Radeon Gallium3D results, the plan was also for some updated Nouveau Gallium3D benchmarks too ahead of the release of Linux 3.8 and Mesa 9.1. Unfortunately, the reverse-engineered open-source NVIDIA support is still very much hit or miss.
The open-source Nouveau driver now has "Reverse PRIME" support.
With Git activity that took place this morning in mainline Mesa, the Nouveau driver now supports hardware-accelerated video decoding for this open-source NVIDIA driver with GeForce 400/500 "Fermi" and GeForce 600 "Kepler" graphics cards using their dedicated video engines.
There's a small point release out for the xf86-video-nouveau X.Org graphics driver.
While NVIDIA has published open-source 2D driver code for their Tegra SoCs, there's DRM library code, and NVIDIA is working with a German company on an open-source driver, there's a small little hold-up in development.
Red Hat's Ben Skeggs pushed out new code this morning into the Nouveau DRM driver repository. In addition to some video BIOS work and other changes, initial support for the NVIDIA GK106 GPU was pushed into this reverse-engineered open-source driver.
One week after NVIDIA published 2D open-source driver code for their Tegra 2 ARM SoCs, which is applied to the Tegra DRM driver that will premiere with the Linux 3.8 kernel, code has now emerged for supporting the NVIDIA Tegra driver within the libdrm component.
More code was pushed to Nouveau's Linux kernel repository for their open-source DRM graphics driver. There's improvements to NVE0/Kepler, a new Falcon engine base class, and a number of other changes that have piled up.
