SCSI_ADJUST_QUEUE_DE(9) SCSI mid layer SCSI_ADJUST_QUEUE_DE(9)NAME
scsi_adjust_queue_depth - Let low level drivers change a device's queue depth
SYNOPSIS
void scsi_adjust_queue_depth(struct scsi_device * sdev, int tagged, int tags);
ARGUMENTS
sdev
SCSI Device in question
tagged
Do we use tagged queueing (non-0) or do we treat this device as an untagged device (0)
tags
Number of tags allowed if tagged queueing enabled, or number of commands the low level driver can queue up in non-tagged mode (as per
cmd_per_lun).
RETURNS
Nothing
LOCK STATUS
None held on entry
NOTES
Low level drivers may call this at any time and we will do the right thing depending on whether or not the device is currently active and
whether or not it even has the command blocks built yet.

adw -- Advansys PCI 16bit SCSI Host adapter driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device pci
device scbus
device adw
DESCRIPTION
This driver provides access to the 16bit SCSI bus connected to the Advanced Systems Products, Inc. ASC3550 Ultra, and ASC38C0800 Ultra2,
SCSI Host Adapter chips. Both chips support, synchronous transfers (20MHz and 40MHz max respectively), 16bit transfers, tagged queueing, and
up to 253 concurrent SCSI transactions.
Per target configuration performed in the AdvanceWare menu, which is accessible at boot, is honored by this driver. This includes synchro-
nous/asynchronous transfers, maximum synchronous negotiation rate, wide transfers, disconnection, tagged queueing, and the host adapter's
SCSI ID. The global setting for the maximum number of tagged transactions allowed per target is not honored as the CAM SCSI system will
automatically determine the maximum number of tags a device can receive as well as guarantee fair resource allocation among devices.
HARDWARE
The adw driver supports SCSI controllers including:
o AdvanSys ABP940UW/ABP3940UW
o AdvanSys ABP950UW
o AdvanSys ABP970UW
o AdvanSys ABP3940U2W
o AdvanSys ABP3950U2W
SEE ALSO adv(4), cd(4), da(4), sa(4), scsi(4)HISTORY
The adw driver appeared in FreeBSD 3.0.
AUTHORS
The adw driver was ported by Justin T. Gibbs from the Linux driver written by Bob Frey of Advanced System Products, Inc. Many thanks to
AdvanSys for providing the original driver under a suitable license for use in FreeBSD.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.

Hello for all,
I am testing the behavior of a 32 bit application running on Solaris 5.10 (SPARC), and realize it reaches 4GB of memory and then crashes.
