* powerd.8: Improve style & fix typosMateusz Piotrowski2020-03-031-23/+26
| | | | | | | | | | | | | | | | - Sort options. - Do not use macros (like .Ar) to specify width for Bl (macros within that string are not expanded). - Use Cm instead of Ar for mode names. - Fix some typos reported by mandoc. - Move the documentation of the PID file from the -P flag description to the FILES section.

* Add -N option to powerd(8) to ignore "nice" time.Colin Percival2020-02-292-10/+26
| | | | | | | | | | | | | | | | | With powerd_flags="-N", this makes powerd(8) exclude "nice" time when computing the CPU utilization. This makes it possible to prevent CPU-intensive "background" processes from spinning up the CPU. Note that only *userland* CPU usage belonging to "nice" processes is excluded; we do not track whether time spent in the kernel is on behalf of nice or non-nice processes, so kernel-intensive nice processes can still result in the CPU being sped up.

| | | | | | | | | | | | | | | | | | | | | | | This change allows to determine power source via sysctl or /dev/apm when devd(8) is running (used by default). Based on patch from PR; other changes on top of it: - '-f' (force) -> '-s' (source) parameter renaming; - allow 'apm' -> 'devd' transition when '-s devd' is set (if APM is enabled); - man page update.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Make it more SMP polite. Previous version uses average CPU load that often leads to load underestimation. It make powerd with default configuration unusable on systems with more then 2 CPUs. I propose to use summary load instead of average one. IMO this is the best we can do without specially tuned scheduler. Also as soon as measuring total load on SMP systems is more useful then total idle, I have switched to it. 2. Make powerd's operation independent from number and size of frequency levels. I have added internal frequency counter which translated into real frequencies only on a last stage and only as good as gone. Some systems may have only several power levels, while others - many of them, so adaptation time with previous approach was completely different. 3. As part of previous I have changed adaptive mode to rise frequency on demand up to 2 times and fall on 1/8 per time internal. 4. For desktop (AC-powered) systems I have added one more mode - "hiadaptive". It rises frequency twice faster, drops it 4 times slower, prefers twice lower CPU load and has additional delay before leaving the highest frequency after the period of maximum load. This mode was specially made to improve interactivity of the systems where operation capabilities are more significant then power consumption, but keeping maximum frequency all the time is not needed. 5. I have reduced default polling interval from 1/2 to 1/4 of second. It is not so important for algorithm math now, but gives better system interactivity.

| | | | | | | | | | | | | | | status. Add a thread that waits for events on the named pipe instead of polling the line status via apm or the ACPI sysctl. Additionally, use robust error handling in case devd goes away or we temporarily can't set a frequency (i.e., passive cooling has preempted our setting). Later, this should be improved so that if adaptive control is not being used, we will block while waiting for AC line events, saving a little CPU.
