CAM stands for Common Access Method. It is a generic way to address the I/O buses in a SCSI-like way. This allows a separation of the generic device drivers from the drivers controlling the I/O bus: for example the disk driver becomes able to control disks on both SCSI, IDE, and/or any other bus so the disk driver portion does not have to be rewritten (or copied and modified) for every new I/O bus. SCSI Interface Modules (SIM) — a Host Bus Adapter drivers for connecting to an I/O bus such as SCSI or IDE. A peripheral driver receives requests from the OS, converts them to a sequence of SCSI commands and passes these SCSI commands to a SCSI Interface Module. The SCSI Interface Module is responsible for passing these commands to the actual hardware (or if the actual hardware is not SCSI but, for example, IDE then also converting the SCSI commands to the native commands of the hardware).

Because we are interested in writing a SCSI adapter driver here, from this point on we will consider everything from the SIM standpoint. The first thing each SIM driver must do is register itself with the CAM subsystem. Here SIZE is the size of the queue to be allocated, maximal number of requests it could contain. It is the number of requests that the SIM driver can handle in parallel on one SCSI card. Note that if we are not able to create a SIM descriptor we free the devq also because we can do nothing else with it and we want to conserve memory. An interesting question is what to do if a SCSI card has more than one SCSI bus, do we need one devq structure per card or per SCSI bus? The answer given in the comments to the CAM code is: either way, as the driver’s author prefers.
