* Re-enable mbtypes statistics in the mbuf allocator. I disabled theseBosko Milekic2001-09-301-32/+31
| | | | | | | | | | | | | | | | | | | | when I changed the allocator bits. This implements per-CPU mbtypes stats by keeping net number of decrements/increments of a given mbtype per-CPU and then summing all of the per-CPU mbtypes to produce the total net number of allocated mbufs of the given mbtype. Counters are carefully balanced to avoid/prevent underflows/overflows. mbtypes stats are re-enabled with the idea that we may occasionally (although very rarely) observe slight inconsistencies in the stat reporting. Most of the time, we should be fine, though. Also make appropriate modifications to netstat(1) and systat(1) to do the necessary reporting.

* - Do not handle the per-CPU containers in mbuf code as though the cpuidsBosko Milekic2001-07-261-8/+5
| | | | | | | | | | | | | | | | | | | | were indices in a dense array. The cpuids are a sparse set and treat them as such, setting up containers only for CPUs activated during mb_init(). - Fix netstat(1) and systat(1) to treat the per-CPU stats area as a sparse map, in accordance with the above. This allows us to properly boot with certain CPUs disactivated. However, if we later decide to re-activate said CPUs, we will barf until we decide to implement CPU spinon/spinoff callback hooks to allow for said CPUs' per-CPU containers to get configured on their activation.

* Introduce numerous SMP friendly changes to the mbuf allocator. Namely,Bosko Milekic2001-06-221-22/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | introduce a modified allocation mechanism for mbufs and mbuf clusters; one which can scale under SMP and which offers the possibility of resource reclamation to be implemented in the future. Notable advantages: o Reduce contention for SMP by offering per-CPU pools and locks. o Better use of data cache due to per-CPU pools. o Much less code cache pollution due to excessively large allocation macros. o Framework for `grouping' objects from same page together so as to be able to possibly free wired-down pages back to the system if they are no longer needed by the network stacks. Additional things changed with this addition: - Moved some mbuf specific declarations and initializations from sys/conf/param.c into mbuf-specific code where they belong. - m_getclr() has been renamed to m_get_clrd() because the old name is really confusing. m_getclr() HAS been preserved though and is defined to the new name. No tree sweep has been done "to change the interface," as the old name will continue to be supported and is not depracated. The change was merely done because m_getclr() sounds too much like "m_get a cluster." - TEMPORARILY disabled mbtypes statistics displaying in netstat(1) and systat(1) (see TODO below). - Fixed systat(1) to display number of "free mbufs" based on new per-CPU stat structures. - Fixed netstat(1) to display new per-CPU stats based on sysctl-exported per-CPU stat structures. All infos are fetched via sysctl. TODO (in order of priority): - Re-enable mbtypes statistics in both netstat(1) and systat(1) after introducing an SMP friendly way to collect the mbtypes stats under the already introduced per-CPU locks (i.e. hopefully don't use atomic() - it seems too costly for a mere stat update, especially when other locks are already present). - Optionally have systat(1) display not only "total free mbufs" but also "total free mbufs per CPU pool." - Fix minor length-fetching issues in netstat(1) related to recently re-enabled option to read mbuf stats from a core file. - Move reference counters at least for mbuf clusters into an unused portion of the cluster itself, to save space and need to allocate a counter. - Look into introducing resource freeing possibly from a kproc.

* Get rid of setgid kmem for systat, and while being there, fix some bugsThomas Moestl2001-03-2310-151/+397
| | | | | | | | | | | | | | and compiler warnings. The data for network statistics are still obtained via the kvm interface if systat was started with the needed privileges, otherwise sysctls are used. The reason for this is that with really many open sockets, the sysctl method is probably slower, but it systat -netstat is probably not really usable in either mode under these conditions.

| | | | | | | | | | | | | | | no longer contains kernel specific data structures, but rather only scalar values and structures that are already part of the kernel/user interface, specifically rusage and rtprio. It no longer contains proc, session, pcred, ucred, procsig, vmspace, pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If any of these changed in size, ps, w, fstat, gcore, systat, and top would all stop working. The new structure has over 200 bytes of unassigned space for future values to be added, yet is nearly 100 bytes smaller per entry than the structure that it replaced.
