-# stalld
-
-The stalld program (which stands for 'stall daemon') is a
-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.
-
-## Command Line Options
-
-`Usage: stalld [-l] [-v] [-k] [-s] [-f] [-h] [-F]
-          [-c cpu-list]
-          [-p time in ns] [-r time in ns]
-          [-d time in seconds] [-t time in seconds]`
-
-### Logging options
-- -l/--log_only: only log information (do not boost) [false]
-- -v/--verbose: print info to the std output [false]
-- -k/--log_kmsg: print log to the kernel buffer [false]
-- -s/--log_syslog: print log to syslog [true]
-
-### 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
-- -p/--boost_period: SCHED_DEADLINE period [ns] that the starving task will receive [1000000000]
-- -r/--boost_runtime: SCHED_DEADLINE runtime [ns] that the starving task will receive [20000]
-- -d/--boost_duration: how long [s] the starving task will run with SCHED_DEADLINE [3]
-- -F/--force_fifo: force using SCHED_FIFO for boosting
-
-### 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]
-### Miscellaneous
-- -h/--help: print this menu

-## Repositories
-The repository at https://gitlab.com/rt-linux-tools/stalld is the main
-repository, where the development takes place.
-
-The repository at https://git.kernel.org/pub/scm/utils/stalld/stalld.git is the
