Redox has been selected for an NGI Zero grant, focusing on implementing POSIX signal handling and process management in userspace. This will allow for significant improvements to the Redox kernel performance. An updated scheme packet format and new syscalls have boosted RedoxFS copy performance by 63%. The kernel is undergoing changes to handle SYS_PREAD2 and SYS_PWRITE2 efficiently. Signal handling improvements have been implemented, with the possibility of further optimizations using shared atomic memory accesses. Not all technical details are finalized, but progress is being made towards a complete POSIX signal support system. Overall, Redox is making strides in improving its kernel and userspace components.
