While we have looked extensively at the performance of generated binaries of user-space applications built under GCC 9, soon we'll be able to benchmark a complete system image built under this annual compiler update to the GNU compiler as Clear Linux is planning a quick roll-out of the soon-to-be-released compiler...

An effort ongoing for a few years now has been the CONFIG_LOCK_DOWN_KERNEL patches to prevent user-space from being able to modify the kernel image with blocking the ability to load unsigned kernel modules, no writing to /dev/mem, restricting PCI BAR and MSR access, ACPI restrictions, and more. Some Linux distributions are already carrying this work in some form and enabling it with UEFI SecureBoot, but it hasn't been mainlined although could soon change...

The Talos Principle was the launch title for Vulkan 1.0 when the graphics API debuted three years ago as an alternative to Croteam's OpenGL renderer. Since then Croteam has rolled out its Vulkan support to their other games and now they are in the process of finally phasing out the OpenGL renderer with The Talos Principle. Here's a last look at how the OpenGL and Vulkan performance compares for this multi-platform game.
