Back in February I wrote about Intel's open-source graphics driver engineers working on a new adaptive sharpening filter capability to be found with upcoming Xe2 graphics starting with Lunar Lake. This new adaptive sharpening filter has minimal power and performance impact and at least according to the driver engineers is working out rather well. Besides the Intel Xe kernel driver support around enabling this adaptive sharpening filter, Intel has also been readying the rest of the Linux desktop stack for exposing this capability...

It's been nearly one decade since Intel began working on 5-level paging support for the Linux kernel to allow for greater virtual and physical address space with expanding memory sizes. The 5-level paging kernel-side bits were upstreamed back in Linux 4.12 in 2017 and enabled by default since 2019 with Linux 5.5. Intel CPUs for a while (since Ice Lake) have supported 5-level paging and AMD CPUs too since Zen 4. The Linux kernel may move to unconditionally enabling 5-level paging support for x86_64 kernel builds...

In some tests this has yielded as much as a ~15x speed-up to performance for user-space obtaining crypographically secure random number generation. It's looking like for the upcoming Linux 6.11 merge window, this work will finally be merged...

Linux 6.10 introduces DRM Panic for providing a new panic screen in case of kernel errors and situations where the VT support may be disabled. This new kernel functionality is akin to Windows' Blue Screen of Death or thanks to open-source can be adapted to take on other forms such as a black screen of death and conveying monochrome logos rather than ASCII art. New patches provide for the ability to show QR codes of error messages within the DRM Panic screens...
