Hi All,
Using QNX I am developing a FC-driver for some HBA card(I don’t have the
data sheets all i have is Linux driver code for that card).
In QNX I know that I need to develop a block type resource manager. In
linux we have a SCSI subsytem where you can hook your driver
functions(Scsi_Host_Template).
Qnx documentation doesn’t have any DDK for block resource manager. All I
know is the following hierarchy.
devb-aha8 (Adaptec SCSI Driver Process)
|
±io-cam.so (SCSI CAM Manager)
| ±io-disk.so (SCSI CAM Disk Manager)
| ±io-cdrom.so (SCSI CAM CD-ROM Manager)
|
±io-blk.so (File System Manager)
±fs-qnx4.so (QNX4 File System)
±fs-cd.so (ISO9660 File System)
If anyone have the anysort of sample code/guide lines for writing SCSI
device drivers in QNX is of great helpful for me.
Thanks in Advance

Sudhakar,
I’ll repeat myself in the vain hope that someone at QNX will
tell me that I’m all wrong now, and that there is a DDK, or at
least a schedule for its release.
To the best of my knowledge from communications with QNX, the
disk driver DDK is not released, and will not be released until,
well, no-one is saying as far as I know.
