LLVM's HIPSPV Coming Together For AMD HIP To SPIR-V For OpenCL Execution

Phoronix - Tue, 12/21/2021 - 04:45
Last week I wrote about the interesting HIPSPV back-end for LLVM to take AMD HIP code -- which generally starts off as NVIDIA CUDA code to begin with before the HIP-ification -- and to be able to output that from the LLVM compiler stack as the SPIR-V intermediate representation used across OpenCL and Vulkan drivers. The goal with this is to be able to take AMD HIP code and ultimately be able to run it on Intel graphics processors but potentially other vendors/drivers too given the vendor-neutral SPIR-V. More of that HIPSPV work is now hitting mainline LLVM...

Systemd 250 Piles On Yet More Features With New Release Candidate

For the Valve-funded Xrdesktop has allowed GNOME and KDE desktops to be VR-aware, Collabora has been developing WXRD as a standalone Wayland compositor for XR/VR use-cases...

Intel i9-12900K Alder Lake Linux Performance In Different P/E Core Configurations

Phoronix - Mon, 12/20/2021 - 22:06
One of the much requested Linux benchmarks since the debut of Intel Alder Lake last month has been for seeing the Core i9 12900K in different core configurations with its mix of P and E cores. Now that the Linux kernel activity has begun settling down around Alder Lake, here are those benchmarks for reference purposes with toggling Hyper Threading and different P and E core counts enabled.
