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.
