Linux 5.8 Supporting Intel TPAUSE Power-Optimized Delays, TSC Fix When Overclocking

TPAUSE is the new Intel instruction for supporting lightweight power/performance optimized and improved power/performance states for sleeping until the timestamp counter (TSC) has reached a desired value. This new instruction with Intel's Tremont architecture will now be used by Linux 5.8+ on supported CPUs for an optimized power state while waiting on a delay event.

Intel Sends Out Patches Bringing Up The "DG1" Graphics Card Under Linux

For months now Intel's open-source driver developers have been working on the "Gen12" graphics support needed most notably for Tiger Lake and more recently is also confirmed for Rocket Lake. But Gen12 is also needed for the highly anticipated Xe Graphics with the discrete graphics offerings to come in the months ahead by Intel. Building off the existing Gen12 graphics driver code, Intel today published the first DG1 patches for enabling their first discrete graphics card under Linux.

Intel CET Support Still Getting Squared Away For Linux In 2020

Various open-source patches have gone back to at least 2017 for enabling Intel's Control-Flow Enforcement Technology (CET) for the Linux kernel and related components. This is the Intel feature for helping prevent ROP and COP/JOP style attacks via indirect branch tracking and a shadow stack. Recently there has been a fair amount of CET improvements to the various open-source components.

Intel Rocket Lake Platform Support Added To Mesa 20.2

Last week Intel open-source developers sent out their initial kernel driver patches for Rocket Lake graphics support and now the Rocket Lake platform support has been merged for Mesa 20.2 on the OpenGL/Vulkan driver side.

Intel's High-Performance VP9 Encoder Sees Its Second Release

When it comes to Intel's high performance Scalable Video Technology (SVT) video encoders, SVT-AV1 is the most well known for its great speed and usage by Netflix and others. But Intel SVT also consists of VP9 and HEVC/H.265 encoders too and today brought the debut of SVT-VP9 0.2.

17 Years Later: Intel 865 Chipset Seeing FBC Enabled On Linux

If you are still running any pre-Sandybridge Intel hardware, you should really consider upgrading to modern hardware for the performance and efficiency gains... But should you still be tied to an old i865-based system, there is an improvement coming in 2020 for Linux users.

Intel Gen11+ Graphics See An Easy Bump On Mesa 20.1-devel

There's been a lot of interesting work hitting Mesa Git this week ahead of the Mesa 20.1 code branching and feature freeze. Merged this afternoon was a rather simple optimization benefiting Gen11 (Icelake) and newer for their open-source Vulkan driver, it's such a simple change it is almost surprising it took so long to benefit.

New Intel "Adaptive" P-State Frequency Governor Volleyed For Better GPU-Bound Efficiency

The Intel P-State driver has been going through a number of improvements recently including transitioning to the "Schedutil" governor by default on some systems so far in this governor making use of scheduler utilization data. But Intel's graphics team meanwhile has been working on P-State changes to improve the GPU-bound energy efficiency and that is now spun as a new "adaptive" governor.

Intel SGX Enclaves Support For Linux Sent Out For A 29th Time

Going on since 2016 has been the long-running effort getting the Software Guard Extensions (SGX) support into the mainline Linux kernel. Sent out this week was the SGX foundation patches for the twenty-ninth time as it works to get into shape for upstream acceptance.
