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

| # |
| # The following properties can be used to override tunables in the emul64 |
| # driver. |
| # |
| # emul64_collect_stats 0 means do not collect statistics. |
| # Non-zero means to collect statistics. |
| # Default value is 1. |
| # |
| # emul64_yield_enable Non-zero means that emul64 should |
| # periodically yield the CPU to allow other |
| # activities to happen. Default value is 1. |
| # |
| # emul64_yield_period Number of emul64 I/O operation between |
| # yields of the CPU. Default is 1000. |
| # |
| # emul64_yield_length Amount of time in microseconds that emul64 |
| # should yield the CPU during its periodic |
| # yields. Default is 1000. |
| # |
| # emul64_max_task Maximum number of task elements in the task |
| # queue for each emul64 controller. Default |
| # is 16. |
| # |
| # emul64_task_nthreads Specifies the number of threads that should |
| # be used to process a controller's task |
| # queue. By default this is set at run time |
| # to the number of CPUs on the system. It |
| # should probably only be set in this file |
| # for special purposes. |
| # |
| # The driver has the default values preset, so it is only necessary to |
| # define these properties in this file if you wish to override the default |
| # values. The following commented lines can be used as a prototype for |
| # setting the properties. |
| # |
| #emul64_collect_stats=1; |
| #emul64_yield_enable=1; |
| #emul64_yield_period=1000; |
| #emul64_yield_length=1000; |
