Running PMU-Tools On Modern Intel CPUs

The open-source PMU-Tools package for Linux allows for a number of performance monitoring units / performance counters to be tapped on the latest Intel processors. PMU-Tools builds on top of the Linux kernel's perf subsystem to offer a wealth of information to developers.

Assessing The Current Intel Haswell Linux Experience

Since the Computex launch of Intel's much anticipated Haswell processors at the beginning of the month, there's been much Linux coverage on Phoronix concerning the compatibility and performance of these new Intel processors from both the processing and graphics sides. Here's a summary of all of our discoveries and findings over the past few weeks.

Is Intel Sandy Bridge Getting Faster On Linux?

With the extensive coverage on Phoronix this month of Intel's new Haswell processors on Linux, many articles have shown that when using the latest components (e.g. Linux 3.10 kernel and Mesa 9.2) that the OpenGL performance is a whole lot faster. But are these changes specific to Haswell or benefit Intel's driver as a whole? In this article are new benchmarks from an older Intel "Sandy Bridge" system with HD 3000 graphics to see whether the performance there is also improving with the latest Linux code.

Intel GPU Driver Tries To Rip Out FBDEV Support

Intel's Daniel Vetter is attempting for the Intel DRM graphics driver to remove support for its FBDEV frame-buffer layer with a new patch-set entitled "fbdev no more!", but will this finally usher in the killing of the Linux kernel's FBDEV subsystem?

Intel Gallium3D Driver Now Supports GLSL 1.40

The "Ilo" open-source driver that provides unofficial Intel Gallium3D graphics support for Sandy Bridge and Ivy Bridge graphics cores on Linux now is advertising GLSL 1.40 compliance. The GL Shading Language update comes after landing UBO and TBO support.

Core i7 4770K - HD Graphics 4600 On New Linux Kernels

For the past week on Phoronix since the public debut of Intel's Haswell processors there has been a lot of coverage. The CPU performance is generally great but the Haswell Linux graphics support is still a work-in-progress even though its performance has already evolved a lot. This Sunday are some extra Core i7 4770K benchmarks.

Intel 2.21.9 X.Org Driver Calls Out More Regressions

Chris Wilson of Intel's Open-Source Technology Center is back to pushing out xf86-video-intel driver updates at an expedited rate. Rather than the new releases being about advancing the SNA acceleration architecture or new features, the past few have been about correcting regressions and other bugs.

Intel Works On Intermediate Pixel Storage

A new feature being worked on for the Intel DRM Linux kernel graphics driver is IPS. Short for Intermediate Pixel Storage, this feature should allow modern Intel HD graphics cores to let the CPU enter deeper PC states to increase power-savings.

Benchmarking The Intel P-State, CPUfreq Changes

On Friday there was the controversial news about the Linux "ondemand" cpufreq governor no longer being fit for best performance and power-savings on modern processors. Fortunately, for better handling the CPU frequency stage changes on modern Intel CPUs, Intel recently introduced the new P-State kernel driver.

Linux 3.10 Kernel Benchmarks For Intel Ivy Bridge

Earlier this month I delivered Radeon DRM driver benchmarks and Nouveau DRM driver benchmarks from the in-development Linux 3.10 kernel. Being published this Friday evening are now Intel Ivy Bridge graphics benchmarks from the Linux 3.10 kernel compared to the earlier releases going back to Linux 3.5.
