Developed the foundational memory mapping subsystem for the pincerOS/kernel repository, enabling dynamic kernel memory allocation and management. This work involved implementing mmapv2 support in Rust, introducing new system calls to establish a user and kernel memory mapping interface, and refactoring process memory handling to utilize spin locks for improved concurrency safety. By focusing on kernel development and memory management, the changes enhanced subsystem stability and set the stage for future features such as advanced allocation strategies and paging improvements. The approach prioritized predictable performance under load and provided a robust baseline for ongoing enhancements to the kernel’s memory management capabilities.
