|  | AdvanSys (Advanced System Products, Inc.) manufactures the following | 
|  | RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow | 
|  | (8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI | 
|  | buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit | 
|  | transfer) SCSI Host Adapters for the PCI bus. | 
|  |  | 
|  | The CDB counts below indicate the number of SCSI CDB (Command | 
|  | Descriptor Block) requests that can be stored in the RISC chip | 
|  | cache and board LRAM. A CDB is a single SCSI command. The driver | 
|  | detect routine will display the number of CDBs available for each | 
|  | adapter detected. The number of CDBs used by the driver can be | 
|  | lowered in the BIOS by changing the 'Host Queue Size' adapter setting. |

|  | 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. |
