Some SCSI 1164 devices don't implement this properly; if you want to disable this 1165 feature, enter 0 or 1 here (it doesn't matter which). 1166 1167 The default value is 8 and should be supported by most hard disks. 1168 This value can be overridden from the boot command line using the 1169 'tags' option as follows (example): 1170 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1171 4, set queue depth to 16 for target 2 and target 3 on controller 0 1172 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1173 1174 The normal answer therefore is to go with the default 8 and to use 1175 a boot command line option for devices that need to use a different 1176 command queue depth. 1177 1178 There is no safe option other than using good SCSI devices. 1179 1180config SCSI_NCR53C8XX_MAX_TAGS 1181 int "maximum number of queued commands" 1182 depends on SCSI_ZALON || SCSI_NCR_Q720 1183 default "32" 1184 ---help--- 1185 This option allows you to specify the maximum number of commands 1186 that can be queued to any device, when tagged command queuing is 1187 possible.

For example, a FAST-20 Wide 16 device is 1206 able to transfer data at 20 million 16 bit packets per second for a 1207 total rate of 40 MB/s. 1208 1209 You may specify 0 if you want to only use asynchronous data 1210 transfers. This is the safest and slowest option. Otherwise, specify 1211 a value between 5 and 80, depending on the capability of your SCSI 1212 controller. The higher the number, the faster the data transfer. 1213 Note that 80 should normally be ok since the driver decreases the 1214 value automatically according to the controller's capabilities. 1215 1216 Your answer to this question is ignored for controllers with NVRAM, 1217 since the driver will get this information from the user set-up. It 1218 also can be overridden using a boot setup option, as follows 1219 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1220 for FAST-20 synchronous data transfer (20 mega-transfers per 1221 second). 1222 1223 The normal answer therefore is not to go with the default but to 1224 select the maximum value 80 allowing the driver to use the maximum 1225 value supported by each controller. If this causes problems with 1226 your SCSI devices, you should come back and decrease the value. 1227 1228 There is no safe option other than using good cabling, right 1229 terminations and SCSI conformant devices. 1230 1231config SCSI_NCR53C8XX_NO_DISCONNECT 1232 bool "not allow targets to disconnect" 1233 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1234 help 1235 This option is only provided for safety if you suspect some SCSI 1236 device of yours to not support properly the target-disconnect 1237 feature.
