Building off the work sent out by Google engineers in recent months and merged for Linux 5.8 around RAPL support for AMD Zen / Zen 2 CPUs with supporting the "runtime average power limiting" counters on Linux similar to Intel's longstanding support, that work has continued now with Zen RAPL support in the PowerCap driver...
For those using the Intel ICE Linux network driver that is used for the likes of the E800 series, it's now going to be easier updating the device firmware from Linux...
Worked out in recent months by an Amazon engineer was optional L1 data cache flushing on context switches to allow for greater computer security in an era of data sampling vulnerabilities and other data leakage issues via side channels. It was sent in for Linux 5.8 but Linus Torvalds characterized it as "beyond stupid" and not being convinced by it. Well, now it's been revised but isn't yet clear if it will appease Torvalds for mainline inclusion...
While LLVM 11.0 was branched almost two weeks ago with many new/improved features for this open-source compiler stack, it has taken until today to get into shape for issuing the first release candidate...

With the Intel Core i9 10900K "Comet Lake" processor here are some fresh GCC compiler benchmarks when looking at the performance of GCC 8.4 versus 9.3 versus a 10.2 snapshot while testing with optimization flags of -O2, -O3 -march=native, and -O3 -march=native -flto.
As outlined a few months ago, Intel's future Sapphire Rapids and Alder Lake processors are set to add a SERIALIZE instruction. That SERIALIZE instruction ensures all flags/register/memory modifications are complete as well as draining all buffered writes to memory before the next instruction is executed. Linux is moving forward with preparing to make use of this new CPU instruction in its function for stopping speculative execution and prefetching of modified code...
DragonFlyBSD developer François Tigeot continues his trek of near single-handedly porting the Intel and Radeon DRM graphics driver code from the Linux kernel to this BSD...
MikroBUS is the open add-on board standard aiming for "maximum expandability with the smallest number of pins". MikroBUS already has fairly robust industry support particularly in the embedded space while finally a mikroBUS mainline kernel driver may be near for Linux to improve the status quo of driver support...
Linus Torvalds has performed his usual Sunday dance and released the Linux 5.8-rc7 kernel as one of the final test releases before Linux 5.8 is declared stable in August...
While the current Vulkan API is exhaustive enough to implement full-featured Wayland compositors and X11 window managers, to date there hasn't been too much adoption considering OpenGL is still more pervasive among hardware/drivers and it's obviously a significant effort writing a new compositor from scratch. One of the leading (among few) examples of a Vulkan-powered window manager / compositor is ChamferWM, which does continue to be developed. SWVKC meanwhile is one that has been seeing development this year as an alpha-stage Wayland Vulkan compositor...
Set to be formally introduced next quarter alongside Phoronix Test Suite 10.0 is the long-overdue overhaul of OpenBenchmarking.org -- the biggest upgrade to our public "cloud" platform for benchmark aggregation and result analytics since its debut nearly one decade ago. Before then, a public beta of OpenBenchmarking.org should get underway in the next few weeks while here is an early look at some of the changes...
Last month on Phoronix were 350+ benchmarks of the AMD Ryzen 3 3300X vs. Intel Core i3 10100, including a number of Linux gaming performance tests. Following that I also ran some tests with the Core i5 10600K tossed in for those that may be weighing between the Ryzen 3 / Core i3 vs. Core i5 for gaming. Here are those additional data points...
Making waves just over a year ago in the GNU Compiler Collection community was the "Ranger" project for on-demand range generator that's been worked on for several years at Red Hat. While their goals for GCC 10 didn't pan out, it's looking like in the next few months more of the Ranger infrastructure will land and thus putting it in the window for GCC 11...
