Posted today to the Linux kernel mailing list was the patch series for introducing the AMD ISP4 driver to the mainline kernel. This supports the image signal processor IP that to date is found with HP's Strix Halo powered ZBook Ultra G1a laptop. With time, future AMD Ryzen laptops will also likely be leveraging this ISP technology for offloading more webcamera work from the CPU, but for now the HP ZBook Ultra G1a is the main beneficiary of this open-source driver...

While Linus Torvalds doesn't too often like new kernel options being enabled by default, one area where it has proven beneficial and otherwise an oversight by those configuring their own kernel builds is the architecture-optimized crypto algorithm implementations. Some will enable support for different kernel crypto algorithms only to forget or be unaware that there are CPU architecture specific implementations that can also typically be enabled for much better performance over the common code. Google engineer Eric Biggers has been cleaning this up and BLAKE2s is the latest receiving treatment...

Ahead of the upcoming SUSE Linux Enterprise 16.0 release, SUSE engineers are busy finishing up work on their new "Agama" operating system installer.

Earlier this month I ran some benchmarks of Mesa's Rusticl OpenCL driver against AMD ROCm on Strix Halo. Those benchmarks caught many by surprise with how well that Rust-based open-source OpenCL driver was working on AMD GPUs for being a generic OpenCL implementation built atop Mesa's Gallium3D. For those curious about the potential of Rusticl on the Intel graphics side, here are some Battlemage benchmarks for Rusticl up against Intel's official Compute Runtime driver stack.
