Since late 2020 there had been work by AMD Linux engineers on adding Smart Access Memory (Resizable BAR) support to RadeonSI as the Gallium3D OpenGL driver and improved since that point in the name of performance. However, for this OpenGL driver now they've come to realize the benefits haven't necessarily panned out and the developers went ahead and disabled this SAM/ReBAR support followed by removing the support from this driver...

Back in December initial AMD Zen 4 "znver4" support was merged for the LLVM/Clang 16 compiler. While the "-march=znver4" targeting at least flips on the newly-added AVX-512 instructions with these AMD processors, it was re-using the existing scheduler model from Zen 3. Finally today a tuned Zen 4 scheduler model has landed for what will be found in the LLVM 17 compiler later this year...

This past week saw the first two consumer PCIe 5.0 NVMe solid-state drives released to retail: the Gigabyte AORUS Gen5 10000 and the Inland TD510. I've been testing the Inland TD510 2TB Gen 5 NVMe SSD the past few days. While in simple I/O testing it can hit speeds almost up to 10,000 MB/s reads and writes, for more complex workloads it quickly dropped against popular PCIe Gen 4.0 NVMe SSD options. In my testing thus far of this first consumer Gen5 NVMe SSD it's left me far from impressed.
