Worked on the nanvix/nanvix repository to address a kernel memory management issue involving MMIO bookings. Delivered a targeted bug fix by implementing a verification step that checks if MMIO addresses are tracked by the frame allocator before booking, using the new frame::is_covered() function. Integrated this logic into book_mmio_regions() to skip non-RAM addresses, which reduced misleading error logs and improved boot-time stability for devices mapped outside the sparse bitmap. Refactored error handling in frame::book() for more consistent diagnostics. Demonstrated skills in Rust, kernel development, and memory management, resulting in safer MMIO region handling and clearer system logging.

Apr 1, 2026April 2026 — Nanvix kernel: delivered a targeted memory-management bug fix for MMIO bookings and added robust verification against the frame allocator. Implemented frame::is_covered() and integrated it into book_mmio_regions() to skip non-RAM MMIO addresses, preventing misleading error logs during boot. Refactored booking paths so book() uses a uniform error! response, reducing spurious log noise and improving boot-time stability for devices mapped beyond the sparse bitmap (e.g., LAPIC at 0xFEE0_0000). Commit f3cb90df799e29ec5e7412bf6024bcf043835481 documents the changes. Impact: more reliable boot, clearer diagnostics, and safer MMIO region handling; technologies demonstrated: kernel memory management, frame allocator, sparse bitmap, MMIO region handling, and improved logging.
