Intel Core Ultra 7 "Lunar Lake" Performance Up By ~22% With ASUS Linux Fix

Phoronix - Thu, 10/24/2024 - 03:00
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.

Linus Torvalds Comments On The Russian Linux Maintainers Being Delisted

Phoronix - Thu, 10/24/2024 - 02:00
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...

Gentoo Linux Touts DTrace 2.0 Support

Phoronix - Wed, 10/23/2024 - 22:53
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...

Significant CRC32C Throughput Optimization On The Way To The Linux Kernel

Phoronix - Wed, 10/23/2024 - 21:56
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...
