# Define Different Drive Sizes:
#
# Compute MSB blocks of X GB disk with dc(1):
# X 1024 1024 1024***512/2 32^/16op10op
# Compute LSB blocks of X GB disk with dc(1):
# X 1024 1024 1024***512/2 32^%16op10op
# With nhead = 128 and nsect = 128, Compute ncyl of X GB disk with dc(1):
# X 1024 1024 1024***512/128 128*/16op10op
# Example: for wombat-drive-1_5TB:
# # dc
# 1024 512+1024 1024 1024***512/2 32^/16op10op
# 0

#
# 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;
#emul64_max_task=16;
#emul64_task_nthreads=<ncpu>;
