Some SCSI 1031 devices don't implement this properly; if you want to disable this 1032 feature, enter 0 or 1 here (it doesn't matter which). 1033 1034 The default value is 8 and should be supported by most hard disks. 1035 This value can be overridden from the boot command line using the 1036 'tags' option as follows (example): 1037 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1038 4, set queue depth to 16 for target 2 and target 3 on controller 0 1039 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1040 1041 The normal answer therefore is to go with the default 8 and to use 1042 a boot command line option for devices that need to use a different 1043 command queue depth. 1044 1045 There is no safe option other than using good SCSI devices. 1046 1047config SCSI_NCR53C8XX_MAX_TAGS 1048 int "maximum number of queued commands" 1049 depends on SCSI_ZALON 1050 default "32" 1051 help 1052 This option allows you to specify the maximum number of commands 1053 that can be queued to any device, when tagged command queuing is 1054 possible.

The numbers 1071 are respectively the maximum data transfer rates in mega-transfers 1072 per second for each class. For example, a FAST-20 Wide 16 device is 1073 able to transfer data at 20 million 16 bit packets per second for a 1074 total rate of 40 MB/s. 1075 1076 You may specify 0 if you want to only use asynchronous data 1077 transfers. This is the safest and slowest option. Otherwise, specify 1078 a value between 5 and 80, depending on the capability of your SCSI 1079 controller. The higher the number, the faster the data transfer. 1080 Note that 80 should normally be ok since the driver decreases the 1081 value automatically according to the controller's capabilities. 1082 1083 Your answer to this question is ignored for controllers with NVRAM, 1084 since the driver will get this information from the user set-up. It 1085 also can be overridden using a boot setup option, as follows 1086 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1087 for FAST-20 synchronous data transfer (20 mega-transfers per 1088 second). 1089 1090 The normal answer therefore is not to go with the default but to 1091 select the maximum value 80 allowing the driver to use the maximum 1092 value supported by each controller. If this causes problems with 1093 your SCSI devices, you should come back and decrease the value. 1094 1095 There is no safe option other than using good cabling, right 1096 terminations and SCSI conformant devices. 1097 1098config SCSI_NCR53C8XX_NO_DISCONNECT 1099 bool "not allow targets to disconnect" 1100 depends on SCSI_ZALON && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1101 help 1102 This option is only provided for safety if you suspect some SCSI 1103 device of yours to not support properly the target-disconnect 1104 feature.
