Intel Xeon P-State vs. CPUFreq Scaling Tests Show Some Odd Numbers

As we've seen a lot of variation in results with different Intel processors when switching between the Intel P-State and CPUFreq scaling drivers and the different governors, here's some tests when using a 16 thread (eight core + HT) Haswell-EP Xeon processor and testing the different CPU frequency scaling settings in Fedora 21.

Intel Xeons Running Great On MSI's X99 Motherboard With Linux

The latest exciting hardware we've been testing at Phoronix are two Xeon Haswell processors that are compatible with the MSI X99S SLI PLUS motherboard. Needless to say with being an Intel processor and especially a workstation-class product, the Xeon E5-1680 v3 and Xeon E5-2687W v3 are running great with Linux.

Intel's DRM Driver Changes Coming Up For Linux 3.18

I've been writing for a while already about the DRM graphics changes coming to Linux 3.18 even with Linux 3.17 not being quite out yet while courtesy of Intel OTC's Daniel Vetter is a comprehensive list of the i915 DRM changes to be found for the next kernel development cycle.

A Multi-Year Effort Has Started To Better Document Intel's DRM/KMS Driver

One of the most frequent reasons we here when it comes developers not getting involved with the open-source Linux graphics driver development (or even just driver bug-fixing) comes down to the high barrier to entry due to a lack of comprehensive documentation, etc. As one step towards improving the driver documentation situation, Daniel Vetter has begun a long process of documenting the Intel (i915) DRM/KMS kernel driver.

Intel Haswell HD Graphics With CS:GO On Linux

Besides Radeon Gallium3D tests of Counter-Strike: Global Offensive, I also did one test-run this weekend of CS:GO using Intel's "Haswell" HD Graphics with the open-source Mesa driver.

Intel Userptr Support Added To Mesa's DRM Library

With the Linux 3.16 kernel is Intel graphics driver support for Userptr, allows user-space to wrap up malloc'ed memory and turn them into GEM buffer objects. Besides the Intel DDX support, there's now userptr support within Mesa's DRM library.

Intel Haswell-ULT Graphics Don't Change Much With Linux 3.17, Mesa 10.4

The Linux 3.17 kernel that's currently under development does provide many new features overall but for those using the Intel HD Graphics of Haswell-ULT chips, there doesn't appear to be much in the way of any performance improvements and at least no regressions. Likewise, Mesa 10.4 isn't doing too much for the Haswell hardware on the matter of frame-rates.

Intel Skylake's MPX Is Closer To Providing Linux Memory Protection

Besides Intel publicly working on Skylake "Gen9" graphics support for Linux, Intel open-source developers are also working on other areas of Skylake hardware enablement for Linux. Work on supporting the Intel Memory Protection Extensions (MPX) that are new to the Skylake micro-architecture are still being revised for the Linux kernel and the many other operating system code-bases that need to be updated to work with this security feature.

Intel Publishes Initial Skylake Linux Graphics Support

While Intel's Skylake isn't arriving until the second half of 2015 as the successor to Broadwell, the Intel Open-Source Technology Center has already published their initial Linux enablement for Skylake with its HD Graphics "Gen 9" display hardware.

Intel's Core i7 5960X Is Fast & Wonderful Under Linux

After my first X99 motherboard burned up in a strange situation, since yesterday my Core i7 5960X Haswell-E system started working wonderfully with Linux after using a different motherboard. I've been hammering the system hard for the past day and no X99/i7-5960X issues have come about (albeit I've refrained from doing any overclocking or DDR4 tweaking yet) and this high-end $1000+ (USD) CPU is running great under Linux.
