+
+Driver Compile Time Options and Debugging
+
+The following constants can be defined in the source file.
+
+1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
+
+   Enabling this option adds assertion logic statements to the
+   driver. If an assertion fails a message will be displayed to
+   the console, but the system will continue to operate. Any
+   assertions encountered should be reported to the person
+   responsible for the driver. Assertion statements may proactively
+   detect problems with the driver and facilitate fixing these
+   problems. Enabling assertions will add a small overhead to the
+   execution of the driver.
+
+2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
+
+   Enabling this option adds tracing functions to the driver and the
+   ability to set a driver tracing level at boot time.  This option is
+   very useful for debugging the driver, but it will add to the size
+   of the driver execution image and add overhead to the execution of
+   the driver.
+
+   The amount of debugging output can be controlled with the global
+   variable 'asc_dbglvl'. The higher the number the more output. By
+   default the debug level is 0.
+
+   If the driver is loaded at boot time and the LILO Driver Option
+   is included in the system, the debug level can be changed by
+   specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
+   first three hex digits of the pseudo I/O Port must be set to
+   'deb' and the fourth hex digit specifies the debug level: 0 - F.
+   The following command line will look for an adapter at 0x330
+   and set the debug level to 2.
+
+      linux advansys=0x330,0,0,0,0xdeb2
+
+   If the driver is built as a loadable module this variable can be
+   defined when the driver is loaded. The following insmod command
+   will set the debug level to one.
+
+      insmod advansys.o asc_dbglvl=1
+
+   Debugging Message Levels:
+      0: Errors Only
+      1: High-Level Tracing
+      2-N: Verbose Tracing
+
+   To enable debug output to console, please make sure that:
+
+   a. System and kernel logging is enabled (syslogd, klogd running).
+   b. Kernel messages are routed to console output. Check
+      /etc/syslog.conf for an entry similar to this:
+
+           kern.*                  /dev/console
+
+   c. klogd is started with the appropriate -c parameter
+      (e.g. klogd -c 8)
+
+   This will cause printk() messages to be be displayed on the
+   current console. Refer to the klogd(8) and syslogd(8) man pages
+   for details.
+
+   Alternatively you can enable printk() to console with this
+   program. However, this is not the 'official' way to do this.
+   Debug output is logged in /var/log/messages.
+
+     main()
+     {
+             syscall(103, 7, 0, 0);
+     }
+
+   Increasing LOG_BUF_LEN in kernel/printk.c to something like
+   40960 allows more debug messages to be buffered in the kernel
+   and written to the console or log file.
+
+3. ADVANSYS_STATS - Enable statistics (Def: Enabled)
+
+   Enabling this option adds statistics collection and display
+   through /proc to the driver. The information is useful for
+   monitoring driver and device performance. It will add to the
+   size of the driver execution image and add minor overhead to
+   the execution of the driver.
+
+   Statistics are maintained on a per adapter basis. Driver entry
+   point call counts and transfer size counts are maintained.
+   Statistics are only available for kernels greater than or equal
+   to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
+
+   AdvanSys SCSI adapter files have the following path name format:
+
+      /proc/scsi/advansys/{0,1,2,3,...}
+
+   This information can be displayed with cat. For example:
+
+      cat /proc/scsi/advansys/0
+
+   When ADVANSYS_STATS is not defined the AdvanSys /proc files only
+   contain adapter and device configuration information.
+
+Driver LILO Option
+
+If init/main.c is modified as described in the 'Directions for Adding
+the AdvanSys Driver to Linux' section (B.4.) above, the driver will
+recognize the 'advansys' LILO command line and /etc/lilo.conf option.
+This option can be used to either disable I/O port scanning or to limit
+scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
+PCI boards will still be searched for and detected. This option only
+affects searching for ISA and VL boards.
+
+Examples:
+  1. Eliminate I/O port scanning:
+       boot: linux advansys=
+         or
+       boot: linux advansys=0x0
+  2. Limit I/O port scanning to one I/O port:
+       boot: linux advansys=0x110
+  3. Limit I/O port scanning to four I/O ports:
+       boot: linux advansys=0x110,0x210,0x230,0x330
+
+For a loadable module the same effect can be achieved by setting
+the 'asc_iopflag' variable and 'asc_ioport' array when loading
+the driver, e.g.
+
+      insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
+
+If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
+I/O Port may be added to specify the driver debug level. Refer to
+the 'Driver Compile Time Options and Debugging' section above for
+more information.
