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 |

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 |
59 | |
60 | The following constants can be defined in the source file. |
61 | |
62 | 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled) |
63 | |
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. |
72 | |
73 | 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled) |
74 | |
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 |
79 | the driver. |
80 | |
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. |
84 | |
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. |
92 | |
93 | linux advansys=0x330,0,0,0,0xdeb2 |
94 | |
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. |
98 | |
99 | insmod advansys.o asc_dbglvl=1 |
100 | |
101 | Debugging Message Levels: |
102 | 0: Errors Only |
103 | 1: High-Level Tracing |
104 | 2-N: Verbose Tracing |
105 | |
106 | To enable debug output to console, please make sure that: |
107 | |
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: |
111 | |
112 | kern.* /dev/console |
113 | |
114 | c. klogd is started with the appropriate -c parameter |
115 | (e.g. klogd -c 8) |
116 | |
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 |
119 | for details. |
120 | |
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. |
124 | |
125 | main() |
126 | { |
127 | syscall(103, 7, 0, 0); |
128 | } |
129 | |
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. |
133 | |
134 | 3. ADVANSYS_STATS - Enable statistics (Def: Enabled) |
135 | |
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. |
141 | |
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. |
146 | |
147 | AdvanSys SCSI adapter files have the following path name format: |
148 | |
149 | /proc/scsi/advansys/{0,1,2,3,...} |
150 | |
151 | This information can be displayed with cat. For example: |
152 | |
153 | cat /proc/scsi/advansys/0 |
154 | |
155 | When ADVANSYS_STATS is not defined the AdvanSys /proc files only |
156 | contain adapter and device configuration information. |
157 | |
158 | Driver LILO Option |
159 | |
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. |
167 | |
168 | Examples: |
169 | 1. Eliminate I/O port scanning: |
170 | boot: linux advansys= |
171 | or |
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 |
177 | |
178 | For a loadable module the same effect can be achieved by setting |
179 | the 'asc_iopflag' variable and 'asc_ioport' array when loading |
180 | the driver, e.g. |
181 | |
182 | insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330 |
183 | |
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 |
187 | more information. |
