For those wondering whether there will be any exciting improvements with the Intel DRM graphics driver in the Linux 3.18 kernel, here's some OpenGL performance benchmarks.
After two years of development by the Intel Open-Source Technology Center China crew, Beignet 1.0.0 was released this week for providing open-source OpenCL support on Linux.
Intel has sent in another round of graphics driver changes to be queued up in DRM-Next for the Linux 3.19 kernel.
We're still likely about one year out before seeing any Skylake processors released from Intel, but their open-source Skylake graphics enablement continues to flow.
This week Intel updated its Linux Graphics Installer for Fedora 20 and Ubuntu 14.04, but as usual, it's really nothing too special and doesn't earn my high recommendation as there's better ways for users to be running the latest open-source graphics code.
As we've seen a lot of variation in results with different Intel processors when switching between the Intel P-State and CPUFreq scaling drivers and the different governors, here's some tests when using a 16 thread (eight core + HT) Haswell-EP Xeon processor and testing the different CPU frequency scaling settings in Fedora 21.
There's a crazy discount right now for those wishing to buy an Intel Xeon Phi MIC card that's equipped with 57 cores running at 1.1GHz, 8GB of onboard memory, passively cooled, and over 1 TeraFLOP of double-precision compute power. All of this on a PCI Express card for less than... $200 USD!
LunarG in cooperation with Intel discovered a very important performance fix for their DRM driver that will significantly boost the OpenGL performance for "Haswell" HD Graphics on Linux.
The latest exciting hardware we've been testing at Phoronix are two Xeon Haswell processors that are compatible with the MSI X99S SLI PLUS motherboard. Needless to say with being an Intel processor and especially a workstation-class product, the Xeon E5-1680 v3 and Xeon E5-2687W v3 are running great with Linux.
Daniel Vetter has sent in his latest drm-intel-next pull request for DRM graphics driver code targeting the Linux 3.19 kernel.
While drm-next closing in a few weeks for Linux 3.19, Daniel Vetter of Intel's Open-Source Technology Center has written a status update concerning the long ongoing work concerning atomic mode-setting.
Linux video expert Gwenole Beauchesne has landed some Video Acceleration API (VA-API) improvements for the open-source Intel driver.
Now that Linux 3.18-rc1 is out, Intel's Open-Source Technology Center developers responsible for their graphics driver work have begun submitting their changes to drm-next for landing with Linux 3.19.
Jarkko Sakkinen of Intel has published his revised patch series for providing Trusted Platform 2.0 (TPM2) support for the Linux kernel.
Well, this is an exciting way to start off Monday morning... Intel developers published an open-source DRM driver for Imagination Technologies PowerVR decoder hardware.
Intel OpenCL Linux compute support has landed for the forthcoming Broadwell processors.
I've been writing for a while already about the DRM graphics changes coming to Linux 3.18 even with Linux 3.17 not being quite out yet while courtesy of Intel OTC's Daniel Vetter is a comprehensive list of the i915 DRM changes to be found for the next kernel development cycle.
One of the most frequent reasons we here when it comes developers not getting involved with the open-source Linux graphics driver development (or even just driver bug-fixing) comes down to the high barrier to entry due to a lack of comprehensive documentation, etc. As one step towards improving the driver documentation situation, Daniel Vetter has begun a long process of documenting the Intel (i915) DRM/KMS kernel driver.
The latest open-source component of Intel's Linux graphics driver stack receiving hardware enablement for Skylake is libdrm.
Intel's Haihao Xiang has announced the version 1.4.0 release of the VA-API library along with the company's updated VA-API driver.
Besides Radeon Gallium3D tests of Counter-Strike: Global Offensive, I also did one test-run this weekend of CS:GO using Intel's "Haswell" HD Graphics with the open-source Mesa driver.
Earlier this month Intel published initial Skylake Linux graphics support for their DRM kernel driver. Today they have released the Mesa 3D driver support for Skylake, their next-generation architecture coming out by the end of 2015 to succeed Broadwell.
A significant patch-set was published on Saturday night that implements the driver-independent bits of OpenGL 4's ARB_tessellation_shader extension inside Mesa.
Now that OpenGL geometry shaders landed for Intel Sandy Bridge hardware in Mesa and the OpenGL version bumped to 3.2, OpenGL 3.3 has arrived.
For those able to spend $1000+ (USD) on a processor, the Intel Core i7 5960X is a fantastic offering that is still leaving me pleased with the performance after extensive Linux testing.
Those still running Intel "Sandy Bridge" processors with integrated HD Graphics will be ecstatic this morning that the Mesa driver has taken a leap forward.
With the Linux 3.16 kernel is Intel graphics driver support for Userptr, allows user-space to wrap up malloc'ed memory and turn them into GEM buffer objects. Besides the Intel DDX support, there's now userptr support within Mesa's DRM library.
With the drm-next merge window for Linux 3.18 closing, Intel's open-source developers have submitted another round of changes for ultimately landing with the Linux 3.18 kernel.
The Linux 3.17 kernel that's currently under development does provide many new features overall but for those using the Intel HD Graphics of Haswell-ULT chips, there doesn't appear to be much in the way of any performance improvements and at least no regressions. Likewise, Mesa 10.4 isn't doing too much for the Haswell hardware on the matter of frame-rates.
Besides Intel publicly working on Skylake "Gen9" graphics support for Linux, Intel open-source developers are also working on other areas of Skylake hardware enablement for Linux. Work on supporting the Intel Memory Protection Extensions (MPX) that are new to the Skylake micro-architecture are still being revised for the Linux kernel and the many other operating system code-bases that need to be updated to work with this security feature.
