 # stalld
 
 #### 介绍
-The stalld program (which stands for 'stall daemon') is a
+The stalld program is a mechanism to prevent the starvation of operating system threads in a Linux system.
-mechanism to prevent the starvation of operating system threads in a
-Linux system. The premise is to start up on a housekeeping cpu (one
-that is not used for real-application purposes) and to periodically
-monitor the state of each thread in the system, looking for a thread
-that has been on a run queue (i.e. ready to run) for a specifed length
-of time without being run. This condition is usually hit when the
-thread is on the same cpu as a high-priority cpu-intensive task and
-therefore is being given no opportunity to run.
-When a thread is judged to be starving, stalld changes
-that thread to use the SCHED_DEADLINE policy and gives the thread a
-small slice of time for that cpu (specified on the command line). The
-thread then runs and when that timeslice is used, the thread is then
-returned to its original scheduling policy and stalld then
-continues to monitor thread states.
-There is now an experimental option to boost using SCHED_FIFO. This
-logic is used if the running kernel does not support the
-SCHED_DEADLINE policy and may be forced by using the -F/--force_fifo
-option.

-Startup options
-
--c/--cpu: list of cpus to monitor for stalled threads [all cpus]
--f/--foreground: run in foreground [false but true when -v]
--P/--pidfile: write daemon pid to specified file [no pidfile]
-
-
-Boosting options
-

-Monitoring options
-
--t/--starving_threshold: how long [s] the starving task will wait before being boosted [60]
--A/--aggressive_mode: dispatch one thread per run queue, even when there is no starving
-threads on all CPU (uses more CPU/power). [false]
