While the next-generation Ivy Bridge hardware may not be shown off this week at CES2012 (in public that is, in private that's a different story), what Intel and their partners will be promoting heavily this week in Las Vegas is their "Medfield" platform. But how well supported under Linux is this next-generation Intel mobile platform? Are there going to be more binary blobs coming out for Linux?
It was nearly one year ago to the day that Intel launched their Sandy Bridge processors. While these CPUs with much-improved integrated graphics are now wildly popular for Linux users (and Microsoft Windows users, too), it wasn't without a rough start. But how will Intel's upcoming Ivy Bridge launch fair under Linux as the successor to Sandy Bridge?
Following the September announcement of the Linux-based Tizen platform and that Intel will transition to it from MeeGo, along with other vendors making changes, there's been some controversy.
Intel GMA500 "Poulsbo" graphics have a better out-of-the-box experience under the forthcoming Ubuntu 12.04 LTS release thanks to improvements in the open-source field, but ultimately it's still an ugly mess.
It turns out the semaphore issues for Intel Sandy Bridge Linux users continues to be present and it's resulting in the patch from the recent Intel merge having to be changed at the last minute within the Linux 3.2 kernel.
There's just a week and a half left to the year, but will Intel be successful in their goal of open-source OpenGL 3.0 support in Mesa for their Sandy/Ivy Bridge hardware in 2011? It looks like they will fall just short.
RC6 power-savings is now on by default for Intel Sandy Bridge and Ivy Bridge graphics hardware in the upcoming Linux 3.2 kernel.
Wondering how Intel's SNA acceleration architecture is performing for Ironlake hardware? Here's some benchmarks.
Zhigang Gong of Intel China has published a new Linux patch today that enables the rest of the Glamor acceleration architecture functions to be used by the Intel X.Org driver. Glamor is a new means of accelerating 2D over OpenGL for the DDX driver.
In less than one minute, it's now possible to build the Linux kernel from source on a desktop.
Patches have begun to surface this week from an Intel developer that begin to work on 3D monitor support under Linux.
Keith Packard on Friday evening fired off an email and patch to enable RC6 power-savings support on Intel Sandy Bridge and Ivy Bridge hardware where possible. This hardware feature can decrease power usage while also increasing performance in certain workloads.
Back at XDC2011 Chicago plans were laid by Intel OSTC developers to have OpenGL 3.0 support in Mesa before year's end, but with three weeks left to 2011, will they make this deadline?
A new Intel kernel frame-buffer driver has been published to the Linux kernel mailing list. However, this driver isn't for the current-generation Intel graphics hardware, Ivy Bridge, Haswell, or even for the notorious PowerVR-based Poulsbo.
The 2011Q4 Linux graphics driver package has been released.
Last month there was a presentation in Brazil by Eugeni Dodonov of the Intel Open-Source Technology Center. The focus was on Intel Linux Graphics and the "following the open-source road from kernel to UI tool-kits."
It turns out that the Intel RC6 power-savings feature can be pushed even further.
The Mesa Gallium3D driver for the Intel 965 IGP series and newer (the "i965g" driver) has been deleted from mainline Mesa.
For those wondering what functionality is supported by Intel's open-source GMA500/GMA600 "Poulsbo" DRM driver, here's a list of what works and also what doesn't function.
Intel's finally ready to enable HiZ support by default for Intel Sandy Bridge graphics with their Mesa DRI driver.
Ben Widawsky has published a set of 15 patches as he seeks comments about forced throttling/scheduling support for the Intel Linux DRM graphics driver.
Intel has officially released their xf86-video-intel 2.17.0 DDX driver this afternoon.
While the Intel Mesa DRI Linux graphics driver hit the milestone last week of hitting GLSL 1.30 compliance (for Sandy Bridge hardware) as needed per the OpenGL 3.0 specification, there's still a fair amount of other work to take care of before reaching full GL3 support. There's also some news to report with regard to UXA Glamor acceleration and Intel DRM power management.
For those wondering whether or not the Linux 3.2 kernel will once again up the graphics performance for Intel Sandy Bridge hardware, here are some results.
Intel's Chris Wilson released xf86-video-intel 2.16.902 over the weekend, which brings 126 changes since the last release candidate less than three weeks ago. There's also a new VA-API video acceleration back-end to report on.
Here's quite an unexpected surprise: GL Shading Language 1.30 support in Mesa for Intel Sandy Bridge hardware (Gen6 and newer) is now marked as complete. GLSL 1.30 has been the big item to tackle in obtaining OpenGL 3.0 compliance for this critical open-source graphics component.
Zhigang Gong of Intel has published patches this morning that integrate Glamor acceleration support into the xf86-video-intel DDX driver.
With Intel effectively dropping MeeGo and is investing in the Tizen project instead, many have likely been wondering what's happening with Intel's Wayland situation. After all, Intel had planned to use Wayland on MeeGo Tablet UX this calendar year and they have several developers devoted to this free software project.
The open-source Intel GMA500 driver for supporting Intel Poulsbo, Oaktrail, Cedarview, and Medfield hardware will be moving out of staging.
Intel's Keith Packard and Canonical's Steve Langasek spent some time this weekend working on making the Intel i915 DRM driver to not have its screen flicker at all when booting to Ubuntu Linux.
