Some SCSI 1151 devices don't implement this properly; if you want to disable this 1152 feature, enter 0 or 1 here (it doesn't matter which). 1153 1154 The default value is 8 and should be supported by most hard disks. 1155 This value can be overridden from the boot command line using the 1156 'tags' option as follows (example): 1157 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1158 4, set queue depth to 16 for target 2 and target 3 on controller 0 1159 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1160 1161 The normal answer therefore is to go with the default 8 and to use 1162 a boot command line option for devices that need to use a different 1163 command queue depth. 1164 1165 There is no safe option other than using good SCSI devices. 1166 1167config SCSI_NCR53C8XX_MAX_TAGS 1168 int "maximum number of queued commands" 1169 depends on SCSI_ZALON || SCSI_NCR_Q720 1170 default "32" 1171 ---help--- 1172 This option allows you to specify the maximum number of commands 1173 that can be queued to any device, when tagged command queuing is 1174 possible. The default value is 32. Minimum is 2, maximum is 64. 1175 Modern hard disks are able to support 64 tags and even more, but 1176 do not seem to be faster when more than 32 tags are being used. 1177 1178 So, the normal answer here is to go with the default value 32 unless 1179 you are using very large hard disks with large cache (>= 1 MB) that 1180 are able to take advantage of more than 32 tagged commands. 1181 1182 There is no safe option and the default answer is recommended. 1183 1184config SCSI_NCR53C8XX_SYNC 1185 int "synchronous transfers frequency in MHz" 1186 depends on SCSI_ZALON || SCSI_NCR_Q720 1187 default "20" 1188 ---help--- 1189 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer 1190 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers 1191 are respectively the maximum data transfer rates in mega-transfers 1192 per second for each class. For example, a FAST-20 Wide 16 device is 1193 able to transfer data at 20 million 16 bit packets per second for a 1194 total rate of 40 MB/s. 1195 1196 You may specify 0 if you want to only use asynchronous data 1197 transfers. This is the safest and slowest option. Otherwise, specify 1198 a value between 5 and 80, depending on the capability of your SCSI 1199 controller. The higher the number, the faster the data transfer. 1200 Note that 80 should normally be ok since the driver decreases the 1201 value automatically according to the controller's capabilities. 1202 1203 Your answer to this question is ignored for controllers with NVRAM, 1204 since the driver will get this information from the user set-up. It 1205 also can be overridden using a boot setup option, as follows 1206 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1207 for FAST-20 synchronous data transfer (20 mega-transfers per 1208 second). 1209 1210 The normal answer therefore is not to go with the default but to 1211 select the maximum value 80 allowing the driver to use the maximum 1212 value supported by each controller. If this causes problems with 1213 your SCSI devices, you should come back and decrease the value. 1214 1215 There is no safe option other than using good cabling, right 1216 terminations and SCSI conformant devices. 1217 1218config SCSI_NCR53C8XX_NO_DISCONNECT 1219 bool "not allow targets to disconnect" 1220 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1221 help 1222 This option is only provided for safety if you suspect some SCSI 1223 device of yours to not support properly the target-disconnect 1224 feature.
