During Intel's quarterly earnings call this week it was warned that Broadwell, the successor to Haswell, has been delayed due to a manufacturing problem. But is this actually somewhat refreshing news to Linux users?
A few days back I delivered Linux OpenGL benchmarks of many different Intel graphics processors spanning the Sandy Bridge, Ivy Bridge, and Haswell generations. In this article are complementary Intel 2D benchmarks of the various generations of Intel processors using the now-default SNA acceleration architecture.
In the preceding days Intel has begun making public a number of Linux kernel patches for supporting their yet-to-be-released Merrifield chip.
Chris Wilson of Intel's Open-Source Technology Center released the xf86-video-intel 2.99.904 driver today to wrap up all the bug-fixes that landed in the past week and to say there's one more feature planned to be completed for the 3.0 release.
Patches are still baking to enable the use of Haswell's Resource Streamer by the open-source Intel Linux graphics driver. The resource streamer that's new to Haswell processors have the ability of accelerating certain commands that otherwise take time on the CPU.
The Core i7 4960X Extreme Edition processor is Intel's new $1000+ CPU built atop their "Ivy Bridge" architecture and features six physical cores plus Hyper Threading. The i7-4960X is running at 3.6GHz with a 4.0GHz Turbo Frequency and is all around a super-fast processor. Under Linux, the performance is fantastic and it runs great on modern Linux distributions.
Intel has already queued up a fair amount of changes for their DRM graphics driver in the yet-to-be-started Linux 3.13 kernel, but there's even more work ahead. A new set of patches were pushed into the Intel DRM driver's kernel testing branch with a lot of "cool stuff" according to its developers.
Intel's Chris Wilson has shared new performance data of UXA vs. GLAMOR vs. his prized SNA acceleration architecture for Intel 2D acceleration on the Linux desktop. To no incredible surprise, SNA is far better than UXA and GLAMOR for an Intel Iris Pro 5200 graphics processor.
Chris Wilson of Intel's Open-Source Technology Center has released the xf86-video-intel 2.99.903 as the latest 3.0 pre-release for their X.Org driver.
There's still several more weeks until the Linux 3.12 kernel release, but Intel's open-source developers already have a number of changes queued up for Linux 3.13.
It's been a while since last hearing anything from Intel engineers about their proposed Power Capping Framework or Running Average Power Limit driver for the Linux kernel, but that changed today. New patches have been released for the power monitoring and limiting kernel code.
It's been a while since Intel last updated their open-source GPU Tools package, but they have now put out the intel-gpu-tools 1.4 release along with a commitment to push out new releases on a quarterly basis.
Following this week's Intel Atom Silvermont / Bay Trail launch and my notes about Intel Bay Trail / Silvermont Linux support, improvements for the new Atom SoCs have been committed to the LLVM tree.
Intel recently released the Ivy Bridge Extreme Edition processors and the benchmark results are incredible.
In the months ahead there's going to be a variety of tablets, 2-in-1 devices, and other low-power systems running off Intel Atom Bay Trail / Silvermont SoCs that were announced yesterday. While the new Atoms are exciting for their use of in-house HD Graphics and low-power design, how's the Linux support?
It's IDF week in San Francisco and Intel has formerly unveiled their Bay Trail SoCs. The forthcoming low-power Intel hardware has what's got excited in recent months on the mobile/tablet front since it features in-house Intel HD graphics over licensed graphics IP from Imagination and their PowerVR family.
Luc Verhaegen, the former RadeonHD graphics driver developer at SUSE and now working on the Lima project for reverse-engineering ARM Mali graphics, has shared his thoughts on the recent developments surrounding Intel backing out their XMir driver support.
In preparation for running Intel Haswell Gallium3D benchmarks, this weekend I ran some fresh Mesa 9.1.6 vs. 9.2.0 vs. 9.3-devel tests on an Intel Core i7 "Haswell" system with HD Graphics 4600.
The "Ilo" driver that began targeting Sandy/Ivy Bridge graphics support on the Gallium3D architecture in mainline Mesa now has initial support for Haswell graphics.
In an interesting change of events, the mainline Intel Linux graphics driver has reverted the patch to support XMir -- the X11 compatibility layer for the Mir Display Server in Ubuntu Linux.
Going back to last year Intel Linux developers have been working on Stereo 3D support for their graphics driver. The support is still a work-in-progress but the code is now up to its third revision.
Beignet is an OpenCL Intel IvyBridge/Haswell implementation that's developed at Intel and using a new code-base not based upon Mesa/Gallium3D like the other hardware vendors are doing for their open-source GPU compute strategy. The Beignet developers are now working on making it possible to properly share GL buffers with the Intel Mesa driver.
If you are an owner of Intel "Ironlake" generation hardware, there is still some good open-source Linux graphics driver news. Intel developers have addressed hardware context support for Ironlake Linux graphics and will be re-attempting to enable RC6 power-savings support.
For those curious whether Intel's queued up driver changes for landing in the Linux 3.12 kernel offer much in the way of better performance, for at least common Intel HD Graphics systems it doesn't appear that way.
Chris Wilson has tagged the xf86-video-intel 2.99.901 open-source Intel Linux hardware graphics driver today after making two significant changes: SNA will become the default 2D acceleration method and Canonical's XMir is now supported by the mainline driver.
The Intel Haswell processors with Iris Pro 5200 "GT3e" graphics sports 128MB of embedded DRAM for maximizing the Intel graphics performance. With the Linux 3.12 kernel, this "eLLC cache" is being enabled in full plus other Intel DRM driver changes for benefiting Intel Linux customers.
The Intel X.Org driver has gained virtual output support to extend the local desktop with remote outputs. Simply put, this can help NVIDIA Optimus/Bumblebee users on Linux.
For those curious about the performance of Intel's 520 Series Serial ATA 3.0 solid-state drives under Linux, here are a couple open-source disk performance benchmarks comparing the 120GB Intel SSDSC2CW12 to a few other HDD/SSDs.
An Intel developer has committed an improved platform command to LLVM's debugger for improved interfacing with remote machines.
Beyond making a whole lot of Intel X.Org driver changes and some recent yet-to-be-merged performance improvements, Chris Wilson has put out a new release of the Cairo graphics library.
