interrupt.rs:
- InterruptRemapTable now owns optional DmaBuffer for self-allocated tables
- new_allocated(entry_count) constructor allocates physically contiguous
DMA memory via DmaBuffer::allocate, returns Result
- new(base_addr, size) still works for externally-provided tables
- private addr() helper replaces direct 'base' field access
- len_encoding() returns AMD-Vi log2-encoded IRT length for DTE entries
- physical_address() returns table base physical address
- Remove unused 'warn' and 'error' imports from log crate
amd_vi.rs:
- Use InterruptRemapTable::new_allocated instead of ::new for IRT init
- Cast len_encoding() from u64 to u8 for DeviceTableEntry::set_int_table_len
Verified: iommu crate compiles clean (0 errors, 0 warnings).
unassign_device: clear DTE and submit hardware INVALIDATE_DEVTAB_ENTRY
and INVALIDATE_INTERRUPT_TABLE commands with completion wait (was
previously only clearing the software HashMap).
TRANSLATE opcode (0x0012): walk IOMMU page tables for IOVA-to-physical
address resolution.
fstat: return proper MODE_DIR/MODE_FILE and sizes for all handle kinds
(Root, Control, Domain, Device).
Remove #TODO from recipe.toml.
