We've known that Linux PC vendor System76 has been investing engineering resources into Coreboot support and while not yet ready for end-users, they are making progress. For once it's ready for their customers, they have also begun crafting a graphical user-interface for these firmware upgrades to Coreboot...

At least for the newest Intel Xeon "Cascade Lake" processors, the LLVM Clang compiler is running incredibly well compared to the long-standing GNU Compiler Collection (GCC). Overall, LLVM clang is now nearly at performance parity to GCC 9 and the in-development GCC 10 compilers. Here are some Linux compiler benchmarks using the dual Intel Xeon Platinum 8280 server built around the Gigabyte S3461-3R0.

With the Linux kernel driver support for the upcoming "Navi" graphics cards only having been sent out last week for AMDGPU/AMDKFD, given it was more than 450 patches and more than 400 thousand lines of code (granted much of that automated header files), there was some risk it could be postponed given the imminent cut-off of new material to DRM-Next for Linux 5.3 given the rigid release cycle. Fortunately, that pull request has been honored...

Here's a look at how the RX 590, RX Vega 56, RX Vega 64, and Radeon VII are performing with the newest open-source AMD driver code compared to the NVIDIA Turing line-up backed by their latest binary driver.

As covered last week, the Linux kernel is finally about to see FSGSBASE support a feature supported by Intel CPUs going back to Ivybridge and can help performance. Since that earlier article the FS/GS BASE patches have been moved to the x86/cpu branch meaning unless any last-minute problems arise the functionality will be merged for the Linux 5.3 cycle. I've also begun running some benchmarks to see how this will change the Linux performance on Intel hardware.
