To complement the recent ACPI CPUfreq vs. Intel P-State Scaling With Linux 3.15 testing that was done using an Intel Core i7 Ivy Bridge Extreme Edition system, here's some similar tests done using a low-power Intel Celeron N2820 "Bay Trail" SoC within the Intel NUC.

While improvements to Intel's open-source Linux graphics driver that explicitly target Sandy Bridge hardware is rare these days with the Intel OTC crew being busy with Broadwell, Haswell, and Bay Trail, there is an SNB improvement to report this afternoon. A patch-set has emerged for Sandy Bridge to implement layered rendering and in the process it takes care of a long-time OpenGL performance regression.

Beignet as the open-source project to provide Intel OpenCL support that works with Intel's open-source Linux graphics driver stack is beginning to show signs of maturity and progress so that Intel Linux desktop users can finally begin exploiting the GPGPU potential of their hardware.

Following the benchmarks I posted this morning showing Intel Haswell graphics having some OpenGL slowdowns with the newer Mesa graphics driver code, I tested a sharply different Haswell system to see if the performance differential was also to be found on this Intel ultrabook with Iris Graphics 5100...

As I wrote about when Intel launched the Z97 chipset earlier this month in preparation for the Haswell Refresh and Broadwell CPUs, the Linux compatibility for the new motherboards powered by the Intel 9-Series chipsets should be in good shape. One of the motherboards I have been testing since then is the Gigabyte Z97-HD3.

We're anxious to test out Intel's next-generation Broadwell processors but it doesn't look like they'll be out in time for "back to school" shopping but should certainly arrive in time for the holidays.

We're still a few weeks away from the release of the Linux 3.15 kernel but open-source Intel developers have already sent in another drm-next pull request to land more of their kernel graphics driver changes for Linux 3.16.

Intel this week has released their Intel Graphics Installer 1.0.5 for Linux, which ships their 2014Q1 open-source graphics driver stack. Supported with this quarterly update is now also Ubuntu 14.04 LTS while the other primary target, Fedora, is still obviously at version 20.

Last month Intel announced a new, fan-less Intel NUC Kit, the DE3815TYKHE and it featured an Intel Atom E3815 SoC. While at first I immediately planned to buy one, now that they're available, I've changed my purchase order instead to another DN2820FYKH NUC Kit for Linux usage.

Last year on earlier versions of the Linux kernel we've uncovered performance issues around Intel's P-State / CPUfreq driver that was causing adverse performance in certain configurations. While it looked like most of the Intel CPU clocking issues were resolved in more recent versions of the Linux kernel, it looks like some Linux performance problems are present in Linux 3.14.

For several months now Intel has been working on graphics virtualization support for their HD Graphics hardware on Linux for use by virtual machines. One of their big projects has been XenGT for mediated GPU pass-through with Xen, but here's a full rundown of what they have going for them right now.

Intel developers landed the bulk of the support into Mesa for supporting the GL_INTEL_performance_query extension, which should be able to assist Linux game developers and driver developers in better optimizing software/games for the open-source Linux graphics drivers.
