Having noticed that there is not a big interest in it, among the fellow FreeBSDers, I was about to set off and hack up the scsi subsystem to implement spindown on suspend and spinup on resume of the da devices, when I realized that there seems to be no hook in the SCSI code for this events.
I'm not a device driver expert, so I'm looking for clues. What I mean is that the ata-pci driver, for instance, specifies hooks via the device_method_t structure which is not available in the scsi_all or scsi_da modules. I understand that they are simply different kind of beasts (sitting on different layers of the kernel code), but I was wondering if there might be a similar mechanism to do what I want. So, what is the recommended way (if there is one), to hook a function of the SCSI subsystem to an event like suspend/resume? I would most appreciate if anyone could point me to a suitable document or even anything related to FreeBSD kernel hacking.
