* info about pools is currently given to userland by copying eachdlg2014-07-021-7/+7
| | | | | | | | | | | | | | | | | | | | | | | pools struct out. however, struct pool in the kernel contains lots of things that userland probably isnt interested in, like actual mutexes, and probably shouldnt get easy access to, like pointers to kernel memory via all the lists/trees. this implements a kinfo_pool structure that has only the data that userland needs to know about. it cuts the sysctl code over to building it from struct pool as required and copying that out instead, and cuts userland over to only handling kinfo_pool. the only problem with this is vmstat, which can read kernel images via kvm, which needs some understanding of struct pool. to cope, the struct pool definition is guarded by if defined(_KERNEL) || defined(_LIBKVM) as inspired by sysctl which needs to do the same thing sometimes. struct pool itself is generally not visible to userland though, which is good. matthew@ suggested struct kinfo_pool instead of struct pool_info. the kinfo prefix has precedent. lots of people liked this.

* tweak the mclgeti algorithm to behave better under load.dlg2010-09-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | instead of letting hardware rings grow on every interrupt, restrict it so it can only grow once per softclock tick. we can only punish the rings on softclock ticks, so it make sense to only grow on softclock tick boundaries too. the rings are now punished after >1 lost softclock tick rather than >2. mclgeti is now more aggressive at detecting livelock. the rings get punished by an 8th, rather than by half. we now allow the rings to be punished again even if the system is already considered in livelock. without this diff a livelocked system will have its rx ring sizes scale up and down very rapidly, while holding the rings low for too long. this affected throughput significantly. discussed and tested heavily at j2k10. there are still some games with softnet we can play, but this is a good first step. "put it in" and ok deraadt@ ok claudio@ krw@ henning@ mcbride@ if we find out that it sucks we can pull it out again later. till then we'll run with it and see how it goes.
