Hi all.
Hope everyone had a great Christmas (or holiday in general if you don't celebrate Christmas).
I've got a couple of questions about scsi devices and scsi equivalents of ioctl() calls.
The HDIO_GET_IDENTITY ioctl() call is very useful for IDE devices, and it has a couple of manpages. But I cannot find a simple-enough scsi equivalent. I've looked at the linux/scsi* headers as well as the scsi drivers in the kernel, even including the code that handles the /proc/scsi tree.
I haven't found any simple documentation (manpage style =P) for scsi_ioctl.
Anyhow, all I am looking for is a scsi-equivalent to ioctl(int d, HDIO_GET_IDENTITY, struct hd_driveid *hd)
Also, there are a couple of scsi-related ioctl() calls (most notably the calls that enable and disable tagged command queneing), but none of the good stuff, like a HDIO_GET_IDENTITY equivalent. Why are such calls not implemented in ioctl() for non-IDE devices? It seems to me that perhaps implementing a SCSI_GET_IDENTITY command in ioctl() would make things easier. But then again, I don't do kernel development. =)
Thanks, Mike
