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
