Some SCSI 1038 devices don't implement this properly; if you want to disable this 1039 feature, enter 0 or 1 here (it doesn't matter which). 1040 1041 The default value is 8 and should be supported by most hard disks. 1042 This value can be overridden from the boot command line using the 1043 'tags' option as follows (example): 1044 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 1045 4, set queue depth to 16 for target 2 and target 3 on controller 0 1046 and set queue depth to 10 for target 0 / lun 2 on controller 1. 1047 1048 The normal answer therefore is to go with the default 8 and to use 1049 a boot command line option for devices that need to use a different 1050 command queue depth. 1051 1052 There is no safe option other than using good SCSI devices. 1053 1054config SCSI_NCR53C8XX_MAX_TAGS 1055 int "maximum number of queued commands" 1056 depends on SCSI_ZALON 1057 default "32" 1058 ---help--- 1059 This option allows you to specify the maximum number of commands 1060 that can be queued to any device, when tagged command queuing is 1061 possible.

The numbers 1078 are respectively the maximum data transfer rates in mega-transfers 1079 per second for each class. For example, a FAST-20 Wide 16 device is 1080 able to transfer data at 20 million 16 bit packets per second for a 1081 total rate of 40 MB/s. 1082 1083 You may specify 0 if you want to only use asynchronous data 1084 transfers. This is the safest and slowest option. Otherwise, specify 1085 a value between 5 and 80, depending on the capability of your SCSI 1086 controller. The higher the number, the faster the data transfer. 1087 Note that 80 should normally be ok since the driver decreases the 1088 value automatically according to the controller's capabilities. 1089 1090 Your answer to this question is ignored for controllers with NVRAM, 1091 since the driver will get this information from the user set-up. It 1092 also can be overridden using a boot setup option, as follows 1093 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate 1094 for FAST-20 synchronous data transfer (20 mega-transfers per 1095 second). 1096 1097 The normal answer therefore is not to go with the default but to 1098 select the maximum value 80 allowing the driver to use the maximum 1099 value supported by each controller. If this causes problems with 1100 your SCSI devices, you should come back and decrease the value. 1101 1102 There is no safe option other than using good cabling, right 1103 terminations and SCSI conformant devices. 1104 1105config SCSI_NCR53C8XX_NO_DISCONNECT 1106 bool "not allow targets to disconnect" 1107 depends on SCSI_ZALON && SCSI_NCR53C8XX_DEFAULT_TAGS=0 1108 help 1109 This option is only provided for safety if you suspect some SCSI 1110 device of yours to not support properly the target-disconnect 1111 feature.
