The current r570.144 firmware images use a mix of binary headers and ELF files that are difficult to parse in Rust. The new TLV format uses iterable tag/length/value fields, with a Python script (extract-firmware-nova.py) handling metadata extraction and packaging. The format is still being refined but aims to simplify firmware handling in the Nova driver compared to the approach used by Nouveau. ## Full article daily.dev links to this article rather than hosting it.
