The `Drop` impl calling `unmap_pages()` is good RAII practice. Concern: `BarAccess::bar_offset()` adds `PRAMIN_BASE` (0x700000) to the calculated offset, which seems wrong for BAR1 access. Wait -- looking more carefully, it computes `(vfn_start * PAGE_SIZE) + local_offset` as the raw BAR1 offset. This should be correct since the VFN corresponds to the BAR1 aperture's virtual address space. --- Generated by Claude Code Patch Reviewer
