* Add META_MODE support.Simon J. Gerraty2015-06-131-0/+19
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | Off by default, build behaves normally. WITH_META_MODE we get auto objdir creation, the ability to start build from anywhere in the tree. Still need to add real targets under targets/ to build packages. Differential Revision: D2796 Reviewed by: brooks imp Notes: svn path=/head/; revision=284345

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Use a pipe for reading devd events as another method of getting the AC lineNate Lawson2005-10-192-28/+179
| | | | | | | | | | | | | | | 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.
