A question on low-level driver document

A question on low-level driver document

[Lee Xing]

Hi,

I could find <<SCSI mid_level - lower_lever driver interface>> for Linux kernel 2.6.  Is there a similar document for Linux 2.4?  The interface between mid_level and lower_level has quite a few changes from lk 2.4 to 2.6.

I'm trying to find the call stack after a low-level driver is loaded.  For example, after low-level driver calls scsi_register(), what's next, and how SCSI disks are registered with mid-level.

Thanks,


Lee

Pick up a driver and follow the function pointers for 
Scsi_Host_Template. For example, qlogicfc.c,
static Scsi_Host_Template driver_template = QLOGICFC;
qlogicfc.h for definition of QLOGICFC.

The detect fptr is good starting point.
