x86 Straight Line Speculation CPU Mitigation Appears For Linux 5.17

Phoronix - Thu, 01/13/2022 - 08:30
The Linux 5.17 kernel is introducing support for the x86 straight-line speculation "SLS" mitigation with it becoming increasingly clear modern x86_64 CPUs are susceptible to speculatively executing linearly in memory past an unconditional change in control flow...

Please Join Us In The January 2022 SPDX Community SBOM DocFest

The Linux Foundation - Thu, 01/13/2022 - 06:45

SPDX was designed for tools to produce and consume SBOM documents. A decade of experience has shown us that tools may interpret fields differently – a file may be a valid syntactic SPDX SBOM,  but different tools may fill in different values.  

By coming together as a community to examine the output of multiple tools and to compare/contrast the results, we can refine the guidance to tool vendors and improve the robustness of the ecosystem sharing SPDX documents.   Historically, these events were called Bake-offs, but we’ve evolved them into “DocFests.” 

After a successful SPDX 2.2 DocFest in September of 2021, the SPDX community has decided to host another DocFest on January 27th from 7-11 AM PST. The purpose of this event is to bring together producers and consumers of SPDX documents and discuss differences between tool output and understanding for the same software artifacts. 

Specifically, the goals of this DocFest are to:

  • Come to agreement on how the fields should be populated for a given artifact
  • Identify instances where different use cases might lead to different choices for fields and structures of documents
  • Assess how well the NTIA SBOM minimum elements are covered
  • Create a set of reference SPDX SBOMs as part of the corpus for further tooling evaluation.

This event will require “sweat equity” – participants who can produce SPDX documents are expected to have generated at least one SPDX document from the target set (either source, built from source, or an image/container equivalent). Participants who consume SPDX documents are expected to run at least two SPDX documents through their tooling and share any analysis results. 

Those who have signed up and have submitted files by January 21, 2022, will receive a meeting invite to the DocFest.

To indicate interest to participate, please fill in the following form no later than January 16, 2022: https://forms.gle/Mq7ReinTY6gDL4cs9

Intel Core i5 12400 "Alder Lake": A Great ~$200 CPU For Linux Users

Phoronix - Thu, 01/13/2022 - 04:30
Formally announced at CES, the Core i5 12400 and other Alder Lake non-K desktop CPUs are beginning to appear in retail channels. Last week I was able to buy an Intel Core i5 12400 "Alder Lake" from a major Internet retailer for $209 USD -- and one week later there remains availability during these turbulent supply chain times. The i5-12400 has wound up being a very nice processor for Linux use that exceeded my initial expectations.

Linux Serial Console Driver Lands Patch For Possible ~25% Performance Improvement

Phoronix - Thu, 01/13/2022 - 02:57
It's not an area of Linux hardware performance we normally look at, but thanks to a Red Hat engineer discovering very low serial console performance, there is an improvement queued up for introduction in Linux 5.17.....

Linux 5.17 Adds Support For "The First Usable, Low-Cost RISC-V Platform"

Phoronix - Wed, 01/12/2022 - 22:30
In addition to the prompt support for Qualcomm's Snapdragon 8 Gen 1, another exciting milestone for the in-development Linux 5.17 kernel is introducing mainline support for the StarFive JH7100, which has been trying to make its debut as the first usable and low-cost RISC-V platform...
