| 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. |
