Fedora's FESCo Rejects The Idea Of "-fno-omit-frame-pointer" As Default Compiler Flag
4 Hours Ago - Fedora - Too Much Lost Performance - 11 Comments

The past few months there has been a change proposal discussed around adding "-fno-omit-frame-pointer" to the default compilation flags for packages being built for Fedora Linux. Adding this option would improve the profiling/debug-ability of the packages but with possible performance implications. The Fedora Engineering and Steering Committee (FESCo) has now rejected this contentious change proposal.

AMD EPYC Genoa, Linux 6.1 & Rust Efforts Excited Linux Users In November
5 Hours Ago - Phoronix - November Highlights - Add A Comment

With November now in the books, here is a look back at the most popular original open-source/Linux content on Phoronix from the 245 original articles written by your's truly over the past month. It was an extremely exciting month given the launch of the AMD EPYC 9004 "Genoa" processors with up to 96 cores per socket, AVX-512, and with all of the improvements meant outright insane generational improvement and currently slaughtering the competition. The Linux 6.1 kernel nearing the limelight, early development work on Linux 6.2, and the continued embracing of the Rust programming language by the open-source ecosystem all made for an interesting November.

xf86-video-modesetting X.Org Driver Sees Patch For "TearFree" Page Flipping
30 November 04:15 PM EST - X.Org - xf86-video-modesetting - 10 Comments

While several X.Org DDX drivers in the past have implemented a "TearFree" xorg.conf driver option to try to eliminate screen tearing when running an X.Org Server without a composited environment, the xf86-video-modesetting generic DDX that is widely used has lacked that option. That is until a developer finally stepped up and has pending support for the "TearFree" option.

Intel Arc Graphics A750/A770 Performance Ahead Of Linux 6.2 + Mesa 23.0
30 November 03:30 PM EST - Display Drivers - 15 Comments

Last month when the Intel Arc Graphics A750 and A770 reached retail availability, there was open-source support available for Linux users assuming you were on a new enough kernel and Mesa release plus having to activate the preliminary/experimental hardware support flag. In the time since the open-source Intel dGPU Linux graphics driver support has continued to mature and with the upcoming Linux 6.2 kernel is where DG2/Alchemist graphics have been promoted to stable / supported out-of-the-box. Given this milestone and the upstream Mesa code for the Intel ANV Vulkan and Iris Gallium3D drivers continuing to mature, here are some fresh benchmarks of the Intel Arc Graphics A750/A770 under Linux.

At the start of the year SDL attempted to prefer Wayland over X.Org/X11 thanks to the maturing Wayland support for this widely-used software/hardware abstraction layer by numerous cross-platform games. But that change was later reverted over ecosystem challenges around Wayland. Now as we approach the end of the year, SDL is again trying to prefer Wayland over X11.

Beyond Intel's well regarded open-source software work deep down the stack on everything from ensuring timely new hardware support to optimizing the Linux kernel with various performance optimizations and investing heavily in the upstream GNU and LLVM toolchains (and much more!), they also make terrific software ecosystem advancements higher up the stack. One of their most promising areas of open-source software work in recent years has been around oneAPI. Next week Intel will be hosting a virtual oneAPI DevSummit for AI and HPC where they will be showing off their latest software advancements.

Readfile System Call Patches Revisited For Efficiently Reading Small Files
27 November 10:08 AM EST - Linux Storage - readfile - 15 Comments

Talked about for over two years now has been a "readfile" system call to efficiently read small files. This should be a win when dealing with small files like those exposed via sysfs while it's taken time to come together and stalled out several times. This week Greg Kroah-Hartman has updated the readfile patches leading to hope that this new syscall might finally be on a path for mainlining.

While these days the Intel-owned Habana Labs Linux software stack is a shining example of an open-source AI accelerator solution with mainline kernel driver support and also helping bring together the new compute accelerator subsystem, it wasn't always so blessed. Initially there was the closed-source user-space bits that fortunately last year was opened up with SynapseAI Core.

Intel's IPU6 Webcam Linux Driver Still A Mess, But Some Patches To Help
27 November 06:46 AM EST - Intel - IPU6 MIPI Camera Mess - 12 Comments

While for years Intel has been very well regarded -- and rightfully so -- for their open-source Linux hardware support, occasionally there are exceptions. One such exception currently is Intel's IPU6 drivers for their MIPI cameras found on many newer Alder lake laptops and presumably upcoming Raptor Lake laptops too. The IPU6 drivers remain outside of the Linux kernel and will still likely be that way for sometime.
