Hi fellows, Im working in a project aimed to port Linux virtio to Power Platform, and also documenting vscsi underling operation. While reading ibmvstgt.c driver, I found something I cant understand: The SCSI command is extracted from this transport frame (SRP) and then pushed to the user space daemon 'tgtd' which process it, right? In the case of read/write commands incoming from the initiator (vscsiclient), I guess the command is converted in a new read/write operation which is performed in the physical disk, is it? I couldn't understand how and who calls the read/write function ibmvstgt_rdma() (which effectively put the data from/into the disk) and why this function seems to be called after ibmvstgt_cmd_done() function. Why there isn't a queuecommand function like in ibmvscsiclient.c used by SCSI? I would be very glad if someone could shed me some light.
