The outlook for using Vulkan within machine learning software is quite positive and even able to offer similar performance to NVIDIA's prized CUDA...

Back in 2023 ONNX and AMD announced TurnkeyML as an "AI insights toolchain". There hasn't been too much news about TurnkeyML since then and they now describe the project itself as a "no-code AI toolchain" while this week brought the release of the big TurnkeyML 6.0 software...

A pull request was sent out on Friday that could potentially land for the upcoming Linux 6.15 kernel to transition ARM's kernel entry code from some architecture-specific Assembly over to using the generic entry code path. It means more unification and transitioning some Assembly code over to C, but it also comes with some hits to performance...

Last month I wrote about new code slated to be added for Linux 6.15 that would provide a cross-driver/standardized means of reporting to user-space over hung GPUs. For the likes of the AMD and Intel graphics drivers initially, user-space will be notified via this new wedged event when a GPU is hung in case user-space wants to take additional actions to try to recover the GPU or at least properly note the troubled state of the GPU. There are now proposed patches under review for further extending this functionality...

Last week AMD sent out a big batch of new graphics driver code for Linux 6.15 including new GPU support, OEM i2c support for RGB lighting and other features, and other updates. Another round of AMDGPU/AMDKFD feature code targeting the upcoming Linux 6.15 merge window was sent out on Friday...

A fix was merged to the Linux 6.14 kernel on Friday -- and also for back-porting to existing Linux stable kernels over the coming days -- for fixing an annoying problem with Intel Core 2 processors. The problem, which was introduced to the Linux kernel back in 2019, could lead to system stalls and boot delays for those still using Intel Core 2 CPUs with modern distributions...

Last week I published an article looking at the power efficiency of 5th Gen AMD EPYC "Turin" using the modern AMD P-State driver and the Power Profile options. The AMD P-State driver being used by default now for the EPYC 9005 series processors on Linux 6.12+ and paired with Power Profile option tuning can deliver a nice boost to server energy efficiency with only modest impact to the performance. Today's article are some complementary numbers I carried out recently on a Supermicro server looking at more of the Power Profile Selection options.
