Linus Torvalds Throws Down The Hammer: Extensible Scheduler "sched_ext" In Linux 6.11

Phoronix - Wed, 06/12/2024 - 08:40
The extensible scheduler "sched_ext" code has proven quite versatile for opening up better Linux gaming performance, more quickly prototyping new scheduler changes, Ubuntu/Canonical has been evaluating it for pursuing a more micro-kernel like design, and many other interesting approaches with it. Yet it's remained out of tree but that is now changing with the upcoming Linux 6.11 cycle...

SUSE Working To Upstream RP1 Southbridge Linux Driver For The Raspberry Pi 5

Phoronix - Wed, 06/12/2024 - 04:51
The Raspberry Pi 5 features the "RP1" as the in-house silicon design for the southbridge to this single board computer. The RP1 driver maintained by Raspberry Pi is just found in their downstream kernel while a SUSE engineer is working to rework that driver so that it can be eventually mainlined in the upstream Linux kernel...

Intel's Glibc Non-Temporal Stores Memset Optimization Extended To AMD CPUs

Phoronix - Tue, 06/11/2024 - 22:57
Merged last month to the GNU C Library (glibc) Git code was a new tunable for non-temporal stores for memset. This optimization for glibc's memset performance was limited to Intel processors given at the time it was only tested/benchmarked on Intel CPUs but now it's proven to be useful too for AMD processors...

Red Hat Developing "eu-stacktrace" For Profiling Without Frame Pointers

Phoronix - Tue, 06/11/2024 - 21:45
While last year we saw Fedora to no longer omit the frame pointer to help in debugging/profiling Fedora packages and Ubuntu 24.04 LTS also enabled frame pointers for better debugging/profiling, among other distributions, there is the known performance implications of no longer omitting the frame pointer. But now in aiming to make the best of both worlds, it turns out Red Hat has been developing eu-stracktrace as a new means of profiling without relying on frame pointers...
