Intel Core Ultra 7 "Lunar Lake" Performance Up By ~22% With ASUS Linux Fix
Intel Core Ultra 7 "Lunar Lake" Performance Up By ~22% With ASUS Linux Fix
23 October 03:00 PM EDT - Processors - 10 Comments

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.

Gentoo Linux Touts DTrace 2.0 Support
Gentoo Linux Touts DTrace 2.0 Support
23 October 10:53 AM EDT - Operating Systems - Gentoo Linux + DTrace 2.0 - 1 Comment

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
Significant CRC32C Throughput Optimization On The Way To The Linux Kernel
23 October 09:56 AM EDT - Linux Kernel - Faster CRC32C Performance - 15 Comments

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.

Linux 6.13 To Default To AMD P-State Driver For EPYC 9005 CPUs
Linux 6.13 To Default To AMD P-State Driver For EPYC 9005 CPUs
23 October 06:32 AM EDT - AMD - AMD P-State On EPYC - 1 Comment

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's compiler engineers today posted a number of feature patches for the GNU Compiler Collection (GCC) for enabling new ISA features to be found with next-generation Xeon "Diamond Rapids" processors. Excitingly a number of new Advanced Matrix Extensions (AMX) features are coming with next-gen Intel Xeon.

Suggestion Raised For Using PGO + LLVM BOLT To Optimize More Fedora Packages
Suggestion Raised For Using PGO + LLVM BOLT To Optimize More Fedora Packages
22 October 06:33 AM EDT - Fedora - PGO + LLVM Bolt Binaries - 11 Comments

Outside of the likes of the Arch Linux based CachyOS and Intel's Clear Linux there aren't too many distributions that widely rely on aggressive compiler optimizations in the name of bettering the system performance. A suggestion was raised recently though for Fedora to use profile-guided optimizations (PGO) and post-link optimizations with the likes of LLVM BOLT for more packages, but at this stage it's not clear if such a shift in Fedora package optimizations will actually materialize.

Intel Core Ultra 7 256V Lunar Lake With ASUS Zenbook Performing Better After New Linux Patch
Intel Core Ultra 7 256V Lunar Lake With ASUS Zenbook Performing Better After New Linux Patch
21 October 12:00 PM EDT - Computers - 12 Comments

On Sunday there was a new patch posted by an Intel Linux engineer to boost the Lunar Lake Linux performance out-of-the-box for ASUS laptops by adjusting the new ASUS Intelligent Performance Technology "AIPT" feature so that Linux follows the same behavior as Windows 11. My initial testing of this ASUS AIPT patch has indeed shown the Core Ultra 7 256V "Lunar Lake" yielding much better performance with this patch applied.

Linus Torvalds Growing Frustrated By Buggy Hardware & Theoretical CPU Attacks
Linus Torvalds Growing Frustrated By Buggy Hardware & Theoretical CPU Attacks
21 October 06:55 AM EDT - Linux Kernel - Frustrated Torvalds - 122 Comments

Over the past week Linux creator Linus Torvalds has been active on a Linux kernel mailing list thread around avoiding barrier_nospec() in copy_from_user() due to being "overkill and painfully slow." The conversation evolved into low-level discussions over CPU behavior and how to best handle, differing behavior/requirements with new Intel CPUs supporting Linear Address Masking (LAM), and the overall headaches these days around CPU security mitigations.

Intel Posts Patch For Fixing/Boosting Lunar Lake Linux Performance On ASUS Laptops
20 October 09:18 AM EDT - Intel - ASUS AIPT To Blame - 18 Comments

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.

Concerns Raised Over Bitwarden Moving Further Away From Open-Source
20 October 08:54 AM EDT - Free Software - Bitwarden Non-Open-Source? - 59 Comments

Several Phoronix readers have written in this Sunday over concerns of Bitwarden further moving away from open-source. Bitwarden is a password management service that leverages an encrypted vault and supports multiple clients/platforms. Bitwarden operates on a freemium model and has provided some code as open-source while there are new concerns over Bitwarden further pivoting away from open-source.

With ReiserFS having been deprecated for two years with plans to remove it in 2025, the upcoming Linux 6.13 cycle for what will be the first major kernel release of the new year and past the Linux 6.12 LTS kernel is expected to do just that... ReiserFS is set to be stripped from the mainline kernel codebase.

"100% Free" GNU Boot Discovers Again They Have Been Shipping Non-Free Code
19 October 03:11 PM EDT - GNU - GNU Boot - 57 Comments

GNU Boot is a "100% free software project aimed at replacing the non-free boot software" and is a downstream of Coreboot, GRUB, and SeaBIOS. While priding itself on being "100% free", last December they had to drop some motherboard support and CPU code after discovering they were shipping some files that are non-free by their free software standards. Today they announced another mistake in having inadvertently been shipping additional non-free code.
