Profile Guided Optimizations (PGO) Likely Coming To Linux 5.14 For Clang

Sat, 06/12/2021 - 21:00
Recently the mainline Linux kernel has seen a lot of improvements to its feature set when compiling it under LLVM's Clang rather than GCC as traditionally the only supported compiler. The most recent feature being brought to the Linux kernel when using Clang is finally allowing the use of compiler profile guided optimizations (PGO) for squeezing even greater performance out of the system by letting the compiler leverage the real-world profiles/metrics collected to make more informed code generation / optimization decisions...

Real-Time Support "PREEMPT_RT" For Linux Held Up Due To Lack Of Funding

Fri, 06/11/2021 - 19:00
While there was kernel talk of merging the PREEMPT_RT code in 2020 for this real-time functionality for the Linux kernel, among other times in the past that has yet to happen. These "RT" patches have long been maintained out-of-tree but it turns out that while in the past it was seemingly close for merging, that effort has stalled for lack of funding...

Old Motorola 68000 Systems Can Finally Move Away From Linux's Deprecated IDE Code

Fri, 06/11/2021 - 12:00
Earlier this year was talk of Linux finally removing its legacy IDE subsystem that has been deprecated for years in favor of just maintaining the still-supported libata code for IDE support. The libata path is much better supported and matured for nearly two decades, but one of the holdouts was some Motorola 68000 series hardware -- like early Macintosh computers -- not being supported outside of the legacy context. That is finally set to change with Linux 5.14 so in turn the legacy IDE code will likely be able to be removed soon...

System76 Launch - A Very Well Built, Highly Configurable, Open-Source Keyboard

Fri, 06/11/2021 - 00:20
Last month System76 launched their Launch Configurable Keyboard. They sent over this new open-source keyboard for some brief testing and I must say the build quality has been top notch and while this is their first keyboard they are bringing to market, with their US manufacturing expertise that began with their Thelio computer cases, it has carried forward with their Launch keyboard. This keyboard is beautifully crafted and among the most durable (and heaviest) keyboards I've used in the past two decades. It reminds me of the IBM Model M from a quality perspective but with its own unique advantages.
