1 AdvanSys (Advanced System Products, Inc.) manufactures the following
2 RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow
3 (8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI
4 buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit
5 transfer) SCSI Host Adapters for the PCI bus.
7 The CDB counts below indicate the number of SCSI CDB (Command
8 Descriptor Block) requests that can be stored in the RISC chip
9 cache and board LRAM. A CDB is a single SCSI command. The driver
10 detect routine will display the number of CDBs available for each
11 adapter detected. The number of CDBs used by the driver can be
12 lowered in the BIOS by changing the 'Host Queue Size' adapter setting.

58 Driver Compile Time Options and Debugging
60 The following constants can be defined in the source file.
62 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
64 Enabling this option adds assertion logic statements to the
65 driver. If an assertion fails a message will be displayed to
66 the console, but the system will continue to operate. Any
67 assertions encountered should be reported to the person
68 responsible for the driver. Assertion statements may proactively
69 detect problems with the driver and facilitate fixing these
70 problems. Enabling assertions will add a small overhead to the
71 execution of the driver.
73 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
75 Enabling this option adds tracing functions to the driver and the
76 ability to set a driver tracing level at boot time. This option is
77 very useful for debugging the driver, but it will add to the size
78 of the driver execution image and add overhead to the execution of
81 The amount of debugging output can be controlled with the global
82 variable 'asc_dbglvl'. The higher the number the more output. By
83 default the debug level is 0.
85 If the driver is loaded at boot time and the LILO Driver Option
86 is included in the system, the debug level can be changed by
87 specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
88 first three hex digits of the pseudo I/O Port must be set to
89 'deb' and the fourth hex digit specifies the debug level: 0 - F.
90 The following command line will look for an adapter at 0x330
91 and set the debug level to 2.
93 linux advansys=0x330,0,0,0,0xdeb2
95 If the driver is built as a loadable module this variable can be
96 defined when the driver is loaded. The following insmod command
97 will set the debug level to one.
99 insmod advansys.o asc_dbglvl=1
101 Debugging Message Levels:
103 1: High-Level Tracing
106 To enable debug output to console, please make sure that:
108 a. System and kernel logging is enabled (syslogd, klogd running).
109 b. Kernel messages are routed to console output. Check
110 /etc/syslog.conf for an entry similar to this:
114 c. klogd is started with the appropriate -c parameter
117 This will cause printk() messages to be be displayed on the
118 current console. Refer to the klogd(8) and syslogd(8) man pages
121 Alternatively you can enable printk() to console with this
122 program. However, this is not the 'official' way to do this.
123 Debug output is logged in /var/log/messages.
127 syscall(103, 7, 0, 0);
130 Increasing LOG_BUF_LEN in kernel/printk.c to something like
131 40960 allows more debug messages to be buffered in the kernel
132 and written to the console or log file.
134 3. ADVANSYS_STATS - Enable statistics (Def: Enabled)
136 Enabling this option adds statistics collection and display
137 through /proc to the driver. The information is useful for
138 monitoring driver and device performance. It will add to the
139 size of the driver execution image and add minor overhead to
140 the execution of the driver.
142 Statistics are maintained on a per adapter basis. Driver entry
143 point call counts and transfer size counts are maintained.
144 Statistics are only available for kernels greater than or equal
145 to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
147 AdvanSys SCSI adapter files have the following path name format:
149 /proc/scsi/advansys/{0,1,2,3,...}
151 This information can be displayed with cat. For example:
153 cat /proc/scsi/advansys/0
155 When ADVANSYS_STATS is not defined the AdvanSys /proc files only
156 contain adapter and device configuration information.
160 If init/main.c is modified as described in the 'Directions for Adding
161 the AdvanSys Driver to Linux' section (B.4.) above, the driver will
162 recognize the 'advansys' LILO command line and /etc/lilo.conf option.
163 This option can be used to either disable I/O port scanning or to limit
164 scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
165 PCI boards will still be searched for and detected. This option only
166 affects searching for ISA and VL boards.
169 1. Eliminate I/O port scanning:
170 boot: linux advansys=
172 boot: linux advansys=0x0
173 2. Limit I/O port scanning to one I/O port:
174 boot: linux advansys=0x110
175 3. Limit I/O port scanning to four I/O ports:
176 boot: linux advansys=0x110,0x210,0x230,0x330
178 For a loadable module the same effect can be achieved by setting
179 the 'asc_iopflag' variable and 'asc_ioport' array when loading
182 insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
184 If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
185 I/O Port may be added to specify the driver debug level. Refer to
186 the 'Driver Compile Time Options and Debugging' section above for
