the APIs are documented in reference form at www.alsa-project.org,
which also has pointers to at least two tutorials on using the API.

Driver Problem

[Mohan Kumar M.]

Hi all,
I have written a low level scsi driver for our scsi/raid controller.

The driver is working fine in Kernel v.2.4.18-3, but its not working in
Kernel v.2.4.19 onwards! (System crashes!!!!!)

I am not using interrupts, SG Lists. 

Is SCSI subsystem has been changed from 2.4.18 to 2.4.19??

Can anyone help me to solve this problem?

          =-=
Thanks n Regards,
        Mohan.

The problem I am facing in the driver is:

When I give
   dd if=/dev/zero of=/dev/sda bs=1024 count=100
It works, if I give
   dd if=/dev/zero of=/dev/sda bs=1024 count=1000 (Samething works in Kernel
2.4.18-3)
System crashes.

I am not using interrupt handler and scatter gather lists.

Here is my driver_template structure:

#define MY_SCSI \
{ \
 name: DRVR_NAME, \
 proc_info: myscsi_proc_info,\
 bios_param:myscsi_bios_param,\
 detect:myscsi_detect, \
 info:myscsi_info,\
 release:myscsi_release,\
 command:myscsi_command,\
 queuecommand:myscsi_queuecommand,\
 can_queue:0, \
 this_id:7,\
 cmd_per_lun:1,\
 sg_tablesize:SG_NONE, \
 unchecked_isa_dma:0,\
 highmem_io:1, \
}

          =-=
Thanks n Regards,
        Mohan.
