In an interesting move, Braswell support was added to Coreboot.
I'm told my Core i7-5775C "Broadwell" desktop CPU with Iris Pro 6200 graphics shipped out this morning. A.k.a. next week will be a ton of exciting open-source Linux performance tests on Phoronix of this quad-core Broadwell CPU with Intel's powerful Iris Graphics.
Initial support for Intel's Broxton has been added to their Mesa 3D driver.
In May the LLVM Clang compiler reached the state of complete OpenMP 3.1 support after the liberally licensed compiler saw its OpenMP support stagger for so long out-of-tree. Intel had been leading the recent efforts for getting OpenMP working in Clang and they've continued in working towards OpenMP 4.0 compliance.
Results have started appearing on OpenBenchmarking.org of the new Intel NUC5i7RYB that's powered by an Intel Core i7 "Broadwell" CPU.
Besides Phoronix celebrating its 11th birthday, last week Intel's SNA 2D acceleration architecture had its birthday and turned four years old. While the xf86-video-intel 3.0 DDX driver release is to make SNA the default for 2D acceleration over UXA, there's still no signs of this release happening.
Intel's upcoming Skylake and Broxton hardware will require some binary-only firmware blobs by the i915 DRM kernel graphics driver.
While Mesa 10.7 just recently entered development, the Git code is often benchmarked on Phoronix, and with not having delivered any Intel Broadwell Linux graphics tests in some time, here's the latest numbers as of this weekend.
The Intel Compute Stick packs a lot into a tiny package: 2GB of DDR3L memory, 32GB eMMC storage, Intel Atom Z3735F quad-core processor with Intel HD Graphics, Bluetooth 4.0, 802.11n WiFi, USB 2.0, and a microSD card slot... All into a 103 x 37 x 12 mm package, but how warm does it get under full load? Here's some numbers.
The Atom Z3735F is what powers Intel's Compute Stick. The Z373F has a Scenario Design Power of just 2.2 Watts while being a quad-core 64-bit processor with a clock speed of 1.33GHz and a burst frequency of 1.83GHz. This low-power Atom SoC also has Intel HD Graphics that work fine under Linux. In this article are some early test data from the Intel Compute Stick with Ubuntu Linux.
The Intel Compute Stick has begun shipping, a tiny device that plugs into any HDMI TV or monitor and turns it into a fully-functioning computer. This low-power PC ships with Windows 8.1 or Ubuntu 14.04 LTS, though at the moment the Windows version is first to market with the Ubuntu Compute Stick not widely shipping until June. I have an Intel Compute Stick at Phoronix for testing.
Yesterday I ran some fresh tests of Intel Ivy Bridge on the latest Mesa Git code to see if the performance has changed much recently for the slightly-older generation of Intel HD Graphics. Today I've done some similar tests in kernel-space with the Linux 4.1 kernel.
Most often these days when running Intel Linux graphics tests at Phoronix it's with Haswell, Broadwell, or Bay Trail hardware. However, in being curious if there's any performance improvements for slightly older hardware with Mesa 10.6 or Mesa 10.7-devel Git, I've run some fresh Ivy Bridge numbers.
Some Video Acceleration API updates are coming down the pipe.
David Airlie has pulled Intel's latest batch of changes into DRM-Next that they've been queuing up for merging into the Linux 4.2 kernel.
Back in April Intel enabled the NIR IR by default within their Mesa driver but initially only for fragment shaders. Intel has now enabled NIR usage by default for vertex shaders within their i965 DRI driver.
While writing this morning about Intel Cherryview support being added to Beignet, I also noticed Intel developers have been quietly fleshing out OpenCL 2.0 support for Linux.
Intel's been working on open-source Linux support for Cherryview for more than one year while finally one of the last pieces of the hardware enablement puzzle has landed: OpenCL support for Cherryview.
Intel's Open-Source Technology Center continues to hire new developers for working on their Linux graphics stack. Back in 2013, Intel had 20~30 full-time Linux graphics driver developers and since then that number has only risen.
Another OpenGL 4 extension is nearing completion within the open-source Mesa software library. The extension t his time is ARB_shader_image_load_store, which is needed for OpenGL 4.2 compliance.
One of the big extensions of OpenGL 4.3 and also a requirement of OpenGL ES 3.1 is support for compute shaders. While the work isn't complete yet, Intel's open-source developers are making progress on GL_ARB_compute_shader support.
The new Phoronix.com web server is speeding along this weekend after its deployment. Here's a look in the performance difference.
While the big ACPI and power management changes were sent in more than one week ago for the Linux 4.1 kernel, another batch of ACPI/PM work was sent in this weekend. One of these last-minute changes should end up significantly benefiting the performance of modern Intel Atom Bay/Cherry Trail SoCs.
With the release of Ubuntu 15.04 coming this week I've been busy running some fresh comparison benchmarks between the "Vivd Vervet" and former versions of Ubuntu Linux. For Intel HD Graphics users, in this article are two quick results showing how the performance of Counter-Strike: Global Offensive and Team Fortress 2 has improved on the open-source Intel Linux graphics driver over the past six months between Ubuntu 14.10 and 15.04.
The Intel Windows driver is up to supporting the OpenGL 4.4 specification while the company's open-source Linux graphics driver still doesn't yet fully support OpenGL 4.0.
Turbostat, the open-source Intel program for reporting processor frequency and idle statistics along with other Intel-specific CPU information, will see a few improvements with Linux 4.1.
For those interested in XenGT as Intel's form of mediated GPU pass-through support on Linux, the newest quarterly update has surfaced.
Chris Wilson of Intel's Open-Source Technology Center hasn't yet managed the xf86-video-intel 3.0 DDX release, but over in kernel-space, he's just published a set of 70 new DRM patches for the Intel kernel driver.
There's more improvements in Mesa Git to talk about this week for Intel open-source customers, including those still on older "Gen4" graphics hardware.
Daniel Vetter of Intel today sent in more code for DRM-Next that in turn will be merged for the Linux 4.1 kernel. It was also signaled that the initial hardware enablement of the graphics processor on Intel's upcoming "Broxton" SoC might happen for this next version of the Linux kernel.
