Trying Intel OpenCL On Linux For Video Encoding

Following my testing and reporting last weekend about Intel Beignet starting to provide very usable open-source OpenCL support on Linux, one of the most common requests was to next see if this Intel OpenCL Linux supprot benefits x264 encoding at all.

Intel Beignet Is Working Out Surprisingly Well For OpenCL On Linux

Beignet is the project out of Intel's Open-Source Technology Center for exposing GPGPU/compute capabilities out of Ivy Bridge hardware and newer when using a fully open-source Linux stack. While Beignet differs greatly from Gallium3D's Clover state tracker, this Intel-specific open-source OpenCL implementation is working out quite well for Ubuntu Linux.

Another Intel Linux Power Regression Is Being Investigated

Power regressions are still easy to come by with the Linux kernel and other areas of the open-source stack... Multiple users have been reporting of a recent power increase on newer versions of the Linux kernel, which seem to track down to the Intel i915 DRM driver.

Linux 3.17 Doesn't Boost Ivy Bridge Performance Numbers

Last week I ran some performance tests that found Sandy Bridge was faster with the Linux 3.17 kernel and these performance gains with the still in-development kernel extended beyond just graphics. Curious, I ran some tests this weekend to see whether Intel Ivy Bridge processors were also running faster with Linux 3.17 compared to Linux 3.16 stable.

Intel Sandy Bridge Gains On Linux 3.17 Extend Beyond Graphics

Yesterday I shared some benchmarks showing Intel Sandy Bridge HD Graphics performance increasing on Linux 3.17 for this several year old architecture. This came as a surprise but the good news is the performance improvements on this new Linux kernel don't stop with OpenGL but extend to CPU performance too.

NIR: A New IR Developed For Mesa That's Better Than GLSL IR

Connor Abbott, the open-source developer that began contributing to the Lima Linux graphics driver while a high school student, was interning at Intel this summer even before starting college. Over the summer the focus of his Intel Linux internship was focusing on developing a new intermediate representation for Mesa graphics drivers.

Intel Might Finally Have Linux Frame-Buffer Compression Fixed-Up, On By Default

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.
