# For a simple shield, we can use the shield subcommand as follows;
|
||||
# however, for any setup more comples it is not recommended to use
|
||||
# shield, but instead to use the set and proc subcommands. The reason
|
||||
# is that the shield command has certain side effects which may complicate
|
||||
# the setup. For example, shield marks the cpusets as exclusive.
|
||||
|
||||
##
|
||||
#### Example 1: using the shield subcommand
|
||||
##
|
||||
|
||||
#$CSET_BIN shield --cpu=0
|
||||
|
||||
# Note that this creates CPU 0 as the general processor that runs
|
||||
# everything and all other CPUs are assigned to the shield. This
|
||||
# is a typical simple shielding setup. Adjust if your needs are
|
||||
# different.
|
||||
|
||||
# For shielding kernel threads as well, use the -k switch below instead
|
||||
# of the shield command above.
|
||||
#$CSET_BIN shield --cpu=0 -k
|
||||
|
||||
##
|
||||
#### Example 2: using the set and proc subcommands
|
||||
##
|
||||
|
||||
# To set up the exact same with the set and proc commands, use the
|
||||
# following commands.
|
||||
|
||||
# Note that the CPUs are defined in the CSET_SYSTEM and
|
||||
# CSET_USER variables defined at the begining of this file.
|
||||
# Also you are not limited to call these cpusets "system" and
|
||||
# "user", you can call them anything, just be sure to be
|
||||
# consistent with the names in this script.
|
||||
|
||||
#$CSET_BIN set --set=system --cpu=$CSET_SYSTEM
|
||||
#$CSET_BIN set --set=user --cpu=$CSET_USER
|
||||
|
||||
# And to shield kernel threads, add the following command.
|
||||
|
||||
#$CSET_BIN proc --move --kthread --fromset=root --toset=system
|
||||
|
||||
# Remember status and be verbose
|
||||
rc_status -v
|
||||
;;
|
||||
stop)
|
||||
echo -n "Shutting down cpuset "
|
||||
|
||||
##
|
||||
#### Example 1: using the shield command
|
||||
##
|
||||
|
||||
# To turn the shield off, we use the reset switch to shield. This
|
||||
# will move all tasks to the root cpuset and then remove both user
|
||||
# and system cpusets.
|
||||
|
||||
#CSET_BIN shield --reset
|
||||
|
||||
##
|
||||
#### Example 2: using the set and proc subcommands
|
||||
##
|
||||
|
||||
# Note that we can simply remove the cpusets which will automatically
|
||||
# move the tasks in those cpusets to their parents; however, manually
|
||||
# moving tasks first gives more flexibility to more complex cpuset
|
||||
# configurations.
|
||||
|
||||
#$CSET_BIN proc --move --kthread --force --fromset=system --toset=root
|
||||
#$CSET_BIN proc --move --kthread --force --fromset=user --toset=root
|
||||
|
||||
# And now, destroy the cpusets
|
||||
|
||||
#$CSET_BIN set --set=system --destroy
|

#$CSET_BIN set --set=user --destroy
