For the recently launched AMD EPYC 9005 series "Turin" processors there is good support out-of-the-box running on the likes of Linux 6.8 as found with Ubuntu 24.04 LTS. The one exception is if wanting to engage CPU power monitoring you need a RAPL/PowerCap patch that was just upstreamed in v6.12. But what about using a newer kernel for greater performance in light of all the upstream optimizations to the kernel in general? Here are some Linux 6.8 vs. 6.11 vs. 6.12 kernel benchmarks on a dual AMD EPYC 9755 server...

Following the ASUS AIPT patch posting this weekend from an Intel Linux engineer that was analyzing my previously-published Lunar Lake results showing rather poor performance on the ASUS Zenbook S 14, the performance has been looking much better. On Monday I posted updated Intel Xe2 graphics results showing strong uplift now that the ASUS Lunar Lake laptop was operating in its standard mode rather than whisper mode. In today's article is data from more than 400 CPU/system benchmarks to see how the Core Ultra 7 256V performance has improved with this new Linux kernel patch and compared to the prior AMD Ryzen and Intel Core laptop comparison data.

Following yesterday's news first featured on Phoronix of several Linux driver maintainers being de-listed from their maintainer positions within the mainline Linux kernel over their connections to Russia, Linus Torvalds has today commented on the matter...

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.

Since purchasing an Intel Core Ultra Series 2 "Lunar Lake" laptop for Linux testing last month, the performance has been coming in below expectations. Among the tests were finding Xe2 graphics on Lunar Lake performing slower that under Windows 11 and in comparison slower than Meteor Lake graphics on Linux. Intel engineers have been able to reproduce my original findings and they uncovered the culprit is a new ASUS laptop feature called AIPT. In turn a patch was posted today for supporting ASUS AIPT controls under Linux to fix this low Lunar Lake Linux performance...
