Of course we are ready to support the community if any help is needed. Is there interest in support for the FWHT format only for testing purpose or you want a full-featured implementation on the QEMU side? Please note that the spec is not finalized yet and a major update is now discussed with upstream and the Chrome OS team, which is also interested and deeply involved in the process. The update mostly implies some rewording and reorganization of data structures, but for sure will require a driver rework. Best regards, Dmitry. On Samstag, 9.
