Some SCSI 1218 devices don't implement this properly; if you want to disable this 1219 feature, enter 0 or 1 here (it doesn't matter which). 1220 1221 The default value is 8 and should be supported by most hard disks. 1222 This value can be overridden from the boot command line using the 1223 'tags' option as follows (example): 1224 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1225 4, set queue depth to 16 for target 2 and target 3 on controller 0 1226 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1227 1228 The normal answer therefore is to go with the default 8 and to use 1229 a boot command line option for devices that need to use a different 1230 command queue depth. 1231 1232 There is no safe option other than using good SCSI devices. 1233 1234config SCSI_NCR53C8XX_MAX_TAGS 1235 int "maximum number of queued commands" 1236 depends on SCSI_ZALON || SCSI_NCR_Q720 1237 default "32" 1238 ---help--- 1239 This option allows you to specify the maximum number of commands 1240 that can be queued to any device, when tagged command queuing is 1241 possible.

The numbers 1258 are respectively the maximum data transfer rates in mega-transfers 1259 per second for each class. For example, a FAST-20 Wide 16 device is 1260 able to transfer data at 20 million 16 bit packets per second for a 1261 total rate of 40 MB/s. 1262 1263 You may specify 0 if you want to only use asynchronous data 1264 transfers. This is the safest and slowest option. Otherwise, specify 1265 a value between 5 and 80, depending on the capability of your SCSI 1266 controller. The higher the number, the faster the data transfer. 1267 Note that 80 should normally be ok since the driver decreases the 1268 value automatically according to the controller's capabilities. 1269 1270 Your answer to this question is ignored for controllers with NVRAM, 1271 since the driver will get this information from the user set-up. It 1272 also can be overridden using a boot setup option, as follows 1273 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1274 for FAST-20 synchronous data transfer (20 mega-transfers per 1275 second). 1276 1277 The normal answer therefore is not to go with the default but to 1278 select the maximum value 80 allowing the driver to use the maximum 1279 value supported by each controller. If this causes problems with 1280 your SCSI devices, you should come back and decrease the value. 1281 1282 There is no safe option other than using good cabling, right 1283 terminations and SCSI conformant devices. 1284 1285config SCSI_NCR53C8XX_NO_DISCONNECT 1286 bool "not allow targets to disconnect" 1287 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1288 help 1289 This option is only provided for safety if you suspect some SCSI 1290 device of yours to not support properly the target-disconnect 1291 feature.
