Yesterday I outlined the AMD Radeon DRM graphics changes that were queued up for the Linux 3.13 kernel that will soon be officially under development. Now for Intel Linux customers there's an overview of the Intel DRM graphics driver changes for this next kernel release cycle.
With Mesa 10.0 planned for release this month and to be branched from Git master this coming week, a number of exciting commits landed on Friday for Intel's open-source Mesa DRI graphics driver.
As hopefully a sign that Intel will soon be publishing their open-source graphics driver code for next year's Broadwell platform, new patches emerged today for supporting multiple power wells to be present on "upcoming hardware" out of Intel.
Since last week's release of OS X 10.9 "Mavericks", I've begun benchmarking my few Apple systems to see how the performance compares over OS X 10.8. In this article are our first benchmarks of OS X Mavericks final as we look at how the performance changes for a Haswell-based 2013 MacBook Air.
A set of Linux kernel patches have been proposed to improve vblank time-stamping by the Linux DRM/KMS drivers. This is able to improve the precision and reliability of the KMS drivers of time-stamps for handing VBlank support.
Ahead of the Linux 3.13 kernel merge window in a few weeks time, Intel is seeking review of a proposed Power Supply Charging Framework for the Linux kernel.
Chris Wilson of Intel this morning released an updated xf86-video-intel X.Org driver. With this latest 3.0 pre-release comes support for TearFree on transformed outputs. There's also been other changes.
With our investigation into the potentially large performance changes in the Linux 3.12 kernel due to a CPUfreq change that can vastly improve the 3.12 kernel Radeon graphics performance, I also checked for Core i7 Haswell performance changes with this latest kernel. However, if using a low-end Core i3 CPU is the performance any different for 3.12? Here's test results.
Most often when running Intel Linux graphics benchmarks these days we're using Haswell hardware since that's where the most exciting developments are now happening with it being the latest-generation Intel products. However, we routinely go back and test older generations of hardware. With it having been a while since last running Mesa benchmarks with Ivy Bridge, especially now this week Mesa 10.0 receiving OpenGL 3.3 support, it's time for some new benchmarks.
Eric Anholt at Intel has a new Mesa GLSL patch to add a new pass for their compiler that decreases the number of instructions and can result in performance improvements.
For those curious about how Intel's Many Integrated Core Architecture, in particular the Xeon Phi, works on Linux and can be taken advantage of for multi-threaded programming, here's a guide.
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.
