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.
