Linux 6.12 Finishing The Transition For Moving Intel CPUs Past The "Family 6" Era
Linux 6.12 Finishing The Transition For Moving Intel CPUs Past The "Family 6" Era
7 Hours Ago - Intel - VFM Refactoring - 4 Comments

As written about early in the year, future Intel CPUs will be moving past the "Family 6" identification used since the mid-1990s with the P6 micro-architecture. Since then Intel has continued releasing new CPUs under "Family 6" with different model IDs while AMD has been more open to changing its Family ID every Zen generation or two. With Intel using Family 6 for so long it led to a lot of Linux kernel code just relying on Model ID comparisons for determining between Intel CPU generations and the like. Thus a lot of Intel CPU model handling reworks are needed for preparing future Intel CPU generations that will no longer be in Family 6. With Linux 6.12 it looks like that work will be wrapping up.

16 Hours Ago - Linux Security - Attack Vector Controls - 16 Comments

David Kaplan who is a Senior Fellow at AMD focused on security technologies has published an initial set of Linux kernel patches for "Attack Vector Controls" in rethinking the CPU security mitigation handling. The proposed Attack Vector Controls makes it easier to manage desired security mitigations to have enabled/disabled based upon intent of the system rather than having to be knowledgeable about individual CPU security vulnerabilities and the various tuning knobs.

AMD Submits Initial Zen 5 Enablement For LLVM/Clang Compiler
AMD Submits Initial Zen 5 Enablement For LLVM/Clang Compiler
11 September 12:51 PM EDT - AMD - LLVM Znver5 - 1 Comment

Early in the year we enjoyed seeing AMD Zen 5 "znver5" support upstreamed for the GCC 14 compiler in making it into that annual GNU Compiler Collection feature release. It was great seeing AMD Zen 5 support make it into this open-source compiler well ahead of any Zen 5 products being announced. Since then the GCC support for the new Znver5 target has continued to be improve upon meanwhile we've been waiting to see similar treatment for the LLVM/Clang compiler stack. Finally this week that AMD Zen 5 (znver5) support has been submitted for review in upstreaming it for LLVM.

Motherboard vendors have begun rolling out updated BIOS versions for AMD AM5 platforms that allow a configurable TDP on the Ryzen 5 9600X and Ryzen 7 9700X processors to allow a 105 Watt cTDP compared to the base 65 Watt TDP. For those wondering about the Linux performance and power efficiency impact from running these mid-tier Zen 5 desktop processors at the higher cTDP value, here is the full set of benchmarks compared to my original review data on Linux.

With this past weekend's release of Linux 6.11-rc7, the kernel changes for the week were larger than prior RCs and Torvalds was a bit hesitant on releasing v6.11 this coming Sunday due to the upcoming that takes place next week in Vienna, Austria. But after a bit of time and feedback from other kernel developers, Torvalds is now more inclined to release Linux 6.11 this coming Sunday rather than dragging it out for an extra week.

wolfSSL "Immediately Retired" From Fedora Linux For Failing To Follow Packaging Rules
wolfSSL "Immediately Retired" From Fedora Linux For Failing To Follow Packaging Rules
10 September 08:11 PM EDT - Fedora - wolfSSL + Fedora - 35 Comments

WolfSSL is an embedded SSl/TLS library designed for a range of use-cases and available as open-source under the GNU GPLv2. WolfSSL was recently packaged and added to Fedora Linux since Netatalk began building against wolfSSL and in the longer-term plans to require its use. So the Fedora packager of Netatalk went ahead with packaging up wolfSSL. But this in turn has led to issues and as of today is now being "immediately retired from Fedora."

As part of the ongoing AmpereOne testing at Phoronix with the 192-core AmpereOne A192-32X flagship processor, I've been working on several different Linux distribution benchmarks with this Supermicro AmpereOne server. That comparison in full should be published next week while worth highlighting on its own are some of the gains seen with the in-development CentOS Stream 10 that serves as the upstream to what will be Red Hat Enterprise Linux 10. There are some nice performance gains seen on AArch64 with CentOS Stream 10 compared to CentOS Stream 9.

Merged three years ago in Linux 5.12 was IDMAPPED mounts for new use-cases from containers to systemd-homed. IDMAPPED mounts allow for different mounts to expose the same file or directory with different ownership such as for sharing files between multiple users or multiple systems. With time all of the major Linux file-systems have seen support added for IDMAPPED mounts while for Linux 6.12 support is on the way for FUSE file-systems.
