Canonical To Distribute AMD ROCm Libraries With Ubuntu 26.04 LTS

AMD previously talked of simplifying the in-box Linux support for ROCm during the second half of 2025. So far we haven't seen any groundbreaking changes from that initiative besides AMD working on various package archives/repositories to make it easier to install the latest ROCm on different Linux distributions. But today a big announcement is now public that Canonical with next year's Ubuntu 26.04 LTS release will provide official ROCm packages along with other libraries...

Scheduler Woes: Bisecting Early Performance Regressions Found In Linux 6.19

Yesterday I noted some early performance regressions I've found on the Linux 6.19 kernel compared to Linux 6.18 LTS stable. Those initial benchmarks were on an AMD EPYC server. Since then I've seen many of the same workloads regressing similarly on an AMD Ryzen Threadripper workstation between Linux 6.18 and Linux 6.19 Git. Given the significant impact and AMD Threadripper processors always helping out to speed-up Linux kernel build times to make for a quicker and more manageable kernel bisecting experience, here is a look at some of the results for the Linux 6.19 performance regressions.

Bug-Catching "Smatch" Static Analysis On The Linux Kernel Under Threat Due To Funding Gap

For the past 15 years the Smatch static analysis tool has been routinely run for uncovering countless bugs within the Linux kernel. Dan Carpenter who authored Smatch and has been routinely analyzing the Linux kernel with it has authored more than 5,568 patches over the years to become one of the top bug fixers for the kernel. But his funding at Linaro has been cut and the project's future now in question...
