Cairo 1.18.2 Collects A Year's Worth Of Fixes

Phoronix - Sat, 09/07/2024 - 18:30
Cairo 1.18.2 released this week nearly one year after Cairo 1.18's debut for this cross-platform 2D vector graphics library -- in turn that was the project's first stable release in five years. Cairo is important for the GTK toolkit, Mozilla's Gecko engine, and dozens of other software projects. With Cairo 1.18.2 there are many fixes that have accumulated over the past year for bettering this graphics library...

Intel Graphics Driver With Linux 6.12 Will Finally Report Fan Speeds

Phoronix - Sat, 09/07/2024 - 01:41
Intel has submitted more kernel graphics driver changes for the upcoming Linux 6.12 cycle. Following the pull requests to DRM-Next last week to enable Lunar Lake Xe2 graphics and Battlemage by default, some more lingering feature patches were merged today. Most exciting with this last round of patches before Linux 6.12? Intel graphics card fan speed reporting is finally wired up for their Linux driver...

AMD Zen 5 Not Affected By Inception/SRSO, mitigations=off Yields No Benefit On Ryzen 9000 Series

Phoronix - Fri, 09/06/2024 - 23:27
One of the security changes with AMD Zen 5 processors that I haven't seen AMD publicly mention at least not prominently is that the new cores are not vulnerable to Speculative Return Stack Overflow (SRSO). Unlike Zen 4 and prior, under Linux I noticed that Zen 5 is no longer affected by the SRSO "INCEPTION" vulnerability. But of course there does remain other CPU security mitigations in place carried over from Zen 4. For those wondering about the mitigation costs or if it's worthwhile running Zen 5 with the "mitigations=off" insane mode, here are some benchmarks.

Updated Patches Allow Compiling The Linux Kernel From Within macOS

Phoronix - Fri, 09/06/2024 - 22:41
Back in 2022 were a set of patches that allowed compiling the ARM64 Linux kernel from Apple macOS hosts. The intent was for developers just wanting to do some build/smoke testing from under an Apple Silicon device running macOS to see at least any kernel changes are successfully compiling on macOS with its LLVM/Clang-based toolchain. An updated form of those patches were posted today for review...

Pre-Ordered The ASUS Zenbook S 14 For Intel Core Ultra "Lunar Lake" Linux Testing

Phoronix - Fri, 09/06/2024 - 22:12
With this week's announcement of the Intel Core Ultra 200V Series "Lunar Lake" processors, I've been very eager to try out the Meteor Lake successor for Linux testing. As sadly is usually the case, for delivering Linux support details and performance benchmarks around launch-time I'm typically left buying a laptop retail for Linux testing. In this case after seeing the Lunar Lake laptops announced this week and their availability, I ended up settling on the ASUS Zenbook S 14 (UX5406SA-S14.U71TB) for the initial Core Ultra 200V series Linux review...

Linux Very Close To Enabling Real-Time "PREEMPT_RT" Support

We're very close to the finish line for the mainline Linux kernel being able to enable real-time "PREEMPT_RT" kernel support...
