| 62 | # Define Different emul64 HBA instances and children: |
| 63 | # |
| 64 | # We don't define HBAs by default, other tests that live under pshot |
| 65 | # (like the devfs testsuite) will fail if emul64 is enabled by default. |
| 66 | # The test scripts that use emul64 should enable the required |
| 67 | # emul64.conf configuration (and restore a disabled emul64.conf). |
| 68 | # |
| 69 | # NOTE: As of %E% the sd target driver does not support |
| 70 | # devices >= 2TB. If you configure one format will |
| 71 | # complain: |
| 72 | # The capacity of this LUN is too large. |
| 73 | # Reconfigure this LUN so that it is < 2TB. |
| 74 | # |
| 75 | # Example: |
| 76 | # |
| 77 | #name="emul64" parent="pshot" bus-addr="1" |
| 78 | # targ_0_0= "wombat-drive-1GB", "WOMBAT 1_0_0:1GB"; |
| 79 | # |
| 80 | #name="emul64" parent="pshot" bus-addr="2" |
| 81 | # targ_0_0= "wombat-drive-1TB", "WOMBAT 2_0_0:1TB" |
| 82 | # targ_1_0= "wombat-drive-1_5TB", "WOMBAT 2_1_0:1.5TB"; |

| 87 | # The following properties can be used to override tunables in the emul64 |
| 88 | # driver. |
| 89 | # |
| 90 | # emul64_collect_stats 0 means do not collect statistics. |
| 91 | # Non-zero means to collect statistics. |
| 92 | # Default value is 1. |
| 93 | # |
| 94 | # emul64_yield_enable Non-zero means that emul64 should |
| 95 | # periodically yield the CPU to allow other |
| 96 | # activities to happen. Default value is 1. |
| 97 | # |
| 98 | # emul64_yield_period Number of emul64 I/O operation between |
| 99 | # yields of the CPU. Default is 1000. |
| 100 | # |
| 101 | # emul64_yield_length Amount of time in microseconds that emul64 |
| 102 | # should yield the CPU during its periodic |
| 103 | # yields. Default is 1000. |
| 104 | # |
| 105 | # emul64_max_task Maximum number of task elements in the task |
| 106 | # queue for each emul64 controller. Default |
| 107 | # is 16. |
| 108 | # |
| 109 | # emul64_task_nthreads Specifies the number of threads that should |
| 110 | # be used to process a controller's task |
| 111 | # queue. By default this is set at run time |
| 112 | # to the number of CPUs on the system. It |
| 113 | # should probably only be set in this file |
| 114 | # for special purposes. |
| 115 | # |
| 116 | # The driver has the default values preset, so it is only necessary to |
| 117 | # define these properties in this file if you wish to override the default |
| 118 | # values. The following commented lines can be used as a prototype for |
| 119 | # setting the properties. |
