For years the open-source Intel Linux graphics driver developers have been working on frame-buffer compression (FBC) support but never it's worked out quite good enough to turn it on by default in full. Frame-buffer compression has the ability to reduce power consumption for those using Intel HD Graphics while reducing the amount of memory bandwidth used for screen refreshes. Now though the Intel DRM FBC code has been re-worked and perhaps this time it will be flipped on by default.

Last month I wrote about how the Intel 3.0 X.Org driver has been in development for the better part of a year with no indications of an imminent release. The xf86-video-intel 3.0 release still hasn't happened, but a new development release is out and it packs even more features into this open-source Linux display driver.

For those wishing to better understand more of the internal workings of Intel's i915 DRM driver that provides the kernel-side portion to their Linux graphics driver, Ben Widawsky of the Intel Open-Source Technology Center has written a great blog post that's the start of the series documenting the Global GTT.

The Linux graphics developers within Intel's Open-Source Technology Center have already prepared a fresh batch of changes that will land with the Linux 3.17 kernel -- even though the Linux 3.15 kernel hasn't been released yet and the Linux 3.16 kernel merge window opened early.

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.
