The CPU Performance Of The NVIDIA GB10 With The Dell Pro Max vs. AMD Ryzen AI Max+ "Strix Halo"

With the Dell Pro Max GB10 testing at Phoronix we have been focused on the AI performance with its Blackwell GPU as the GB10 superchip was designed for meeting the needs of AI. Many Phoronix readers have also been curious about the GB10's CPU performance in more traditional Linux workloads. So for those curious about the GB10 CPU performance, here are some Linux benchmarks focused today on the CPU performance and going up against the AMD Ryzen AI Max+ 395 "Strix Halo" within the Framework Desktop.

Adjusting One Line Of Linux Code Yields 5x Wakeup Latency Reduction For Modern Xeon CPUs

A new patch posted to the Linux kernel mailing list aims to address the high wake-up latency experienced on modern Intel Xeon server platforms. With Sapphire Rapids and newer, "excessive" wakeup latencies with the Linux menu governor and NOHZ_FULL configuration can negatively impair Xeon CPUs for latency-sensitive workloads but a 16 line patch aims to better improve the situation. That is, changing one line of actual code and the rest being code comments...

Ryabitsev: Tracking kernel development with korgalore

Konstantin Ryabitsev has put up a blog post about korgalore, a tool he has written to circumvent delivery problems experienced by kernel developers using the large, centralized email systems. We cannot fix email delivery, but we can sidestep it entirely. Public-inbox archives like lore.kernel.org store all mailing list traffic in git repositories. In its simplest configuration, korgalore can shallow-clone these repositories directly and upload any new messages straight to your mailbox using the provider's API.

Remote authentication bypass in telnetd

One would assume that most LWN readers stopped running network-accessible telnet services some number of decades ago. For the rest of you, this security advisory from Simon Josefsson is worthy of note: The telnetd server invokes /usr/bin/login (normally running as root) passing the value of the USER environment variable received from the client as the last parameter. If the client supplies a carefully crafted USER environment value being the string "-f root", and passes the telnet(1) -a or --login parameter to send this USER environment to the server, the client will be automatically logged in as root bypassing normal authentication processes.
