AMD EPYC 7343 / EPYC 7443 Linux Performance
Since the AMD EPYC 7003 "Milan" series launch back in March we have carried out many benchmarks with their flagship processors like the EPYC 7763 and 7713 processors and some of the frequency optimized SKUs, but what about the performance lower down the product stack? Up for benchmarking today is a look at the AMD EPYC 7343 and 7743 processors in 1P and 2P configurations against other AMD EPYC Milan processors as well as Intel's Xeon Platinum 8380 Ice Lake processors.

GCC 11 Compiler Performance Benchmarks With Various Optimization Levels, LTO
Given the recent forum discussion stemming from the -O3 optimization level still too unsafe for the Linux kernel (in part due to older, buggy compilers) and some users wondering about the current -O2 versus -O3 compiler optimization level impact, here is a fresh round of reference benchmarks using GCC 11.1 on Fedora Workstation 33 looking at various optimization levels and optimizations tested on dozens of different application benchmarks to see the overall impact on performance.
ACPI Platform Runtime Mechanism Support Is Getting Underway For Linux
Platform Runtime Mechanism was incorporated into the ACPI 6.4 specification earlier this year and allows moving some system management interrupt (SMI) handlers out of the system management mode (SMM) "black box" and into the OS/VMM execution context. With Linux 5.14 initial work on ACPI Platform Runtime Mechanism is set to land...
Another Intel Sandy/Ivy Bridge Motherboard Now Works For Coreboot (ASUS P8Z77-V)
While Intel engineers have been working on Alder Lake support for Coreboot as with other recent CPU generations that open-source firmware/BIOS support remains focused on their reference boards with a particular focus on meeting necessary requirements for Google Chromebook devices. Sadly, there is not much or any in the way of consumer retail motherboard support at this point. For those looking for retail desktop motherboard support for Coreboot, aside from the open-source POWER9 systems out of Raptor Computing, on the x86_64 front it largely means using aging Intel and AMD platforms...

KWinFT Going Through Code Refactoring, Working On WLROOTS-Based Usage
Announced last year was KWinFT as a fork of KDE's KWin to focus on improving the Wayland support more rapidly and incorporating other modern technologies. KWinFT has been making progress on advancing its code-base while in recent months it was seemingly more quiet. However, it turns out KWinFT is alive and well and has been going through some code refactoring while preparing for the next wave of feature work...
Linux 5.14 To Begin Enabling The Intel Graphics TTM Memory Management Bits for dGPUs
While a decade ago Intel's open-source Linux graphics driver engineers resisted TTM at the time and instead devised the Graphics Execution Manager (GEM) for kernel graphics memory management needs in its place, now with discrete graphics cards and dedicated video memory, Intel has been working on making use of TTM memory management for those purposes. With Linux 5.14 the initial bits are going to be there for using TTM by the Intel driver when running with discrete graphics having local memory...

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