Why has this pull request not been merged? Maybe @flowswitch can provide binaries? |
This repo is very dead, unfortunately. I think @r0m30 has been the only maintainer for a long time, and they're almost or entirely inactive. There's so many things that still need to be done, multiple forks that implement various additional functionality (like sleep support, a better hash function, an updated preboot environment) but nothing gets merged back into here or consolidated elsewhere. I lost track of all the different forks and what they add/improve at this point. |
The JMS583 firmware supports SCSI SECURITY PROTOCOL IN/OUT commands (relaying them to NVMe side correctly), but it also handles the ATA PASS THROUGH command (in a vendor-specific way, implementing an NVMe pass through), so sedutil gets an empty response to ATA PASS THROUGH (but no command error) and treats the drive as SATA w/o OPAL support without trying the SCSI method.
This patch adds probing the SCSI method in case of empty ATA PASS THROUGH response, so the drive gets detected as SAS at the end and works correctly.
