Igalia has recently submitted an updated set of patches for the Linux kernel's FUTEX get_robust_list2 and set_robust_list2 system calls. This development is part of an ongoing effort, active since last year, by the open-source consulting firm to enhance Linux kernel support for ARM64 gaming initiatives. The work aims to improve Steam Play gaming performance on ARM64 architectures and optimize the FEX emulator, which allows x86/x86_64 games to run efficiently on ARM64-based devices like the Steam Frame. These FUTEX syscall enhancements are critical for robust multi-threaded application behavior in such environments.
