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.

121#emul64_collect_stats=1;
122#emul64_yield_enable=1;
123#emul64_yield_period=1000;
