More than a decade ago the DTrace tracing framework from Sun Microsystems was one of the long sought features from Solaris desired by Linux developers. Oracle ended up porting DTrace to Linux over the years but without too much fanfare outside of Oracle Linux especially since the advent of (e)BPF on Linux and other tracing/debugging open-source advancements. With the recent DTrace 2.0, it's now built atop the BPF engine and other upstream kernel tracing features on Linux. Gentoo Linux today announced their support for DTrace 2.0...
Google engineer Eric Biggers has worked on some very nice performance optimizations for the crypto code within the Linux kernel such as faster AES-GCM for Intel and AMD CPUs, much faster AES-XTS disk/file encryption with modern CPUs, and many other optimizations over the years. His latest work is on enhancing the CRC32C crypto performance for x86/x86_64 processors...
Intel engineers this morning sent out their newest pull request of "drm-intel-gt-next" material to queue in DRM-Next ahead of the upcoming Linux 6.13 merge window. There is a new feature enabled on newer Intel graphics hardware as well as some improvements for very old Intel integrated graphics...
It was just earlier this week that AMD posted Linux patches to switch EPYC over to using the AMD P-State driver rather than the long-used generic ACPI CPUFreq driver. This should lead to better power efficiency out-of-the-box and is a change being made just for EPYC 9005 "Turin" CPUs and future server processors. Already it's looking like this change will be introduced for the upcoming Linux 6.13 merge window...
It was just one and a half years ago that Cloudflare began rolling out OpenBMC on their massive array of servers to replace traditional proprietary Baseboard Management Controller (BMC) firmware stacks. Since the end of last year they've been talking up their successes using OpenBMC and now as we approach two years of their OpenBMC use within production, they continue singing the praise of this open-source, Linux-based BMC software stack...
Intel has upstreamed the firmware for their "BlazarU" core to linux-firmware.git for improving the out-of-the-box wireless experience with newer Intel WiFi adapters...
