* Convert socket structures to be type-stable and add a version number.Garrett Wollman1998-05-151-1/+8
| | | | | | | | | | | | | | | | | | | | | | Define a parameter which indicates the maximum number of sockets in a system, and use this to size the zone allocators used for sockets and for certain PCBs. Convert PF_LOCAL PCB structures to be type-stable and add a version number. Define an external format for infomation about socket structures and use it in several places. Define a mechanism to get all PF_LOCAL and PF_INET PCB lists through sysctl(3) without blocking network interrupts for an unreasonable length of time. This probably still has some bugs and/or race conditions, but it seems to work well enough on my machines. It is now possible for `netstat' to get almost all of its information via the sysctl(3) interface rather than reading kmem (changes to follow). Notes: svn path=/head/; revision=36079

* Fix bug related to map entry allocations where a sleep might be attemptedDavid Greenman1997-01-151-2/+2
| | | | | | | | | | | when allocating memory for network buffers at interrupt time. This is due to inadequate checking for the new mcl_map. Fixed by merging mb_map and mcl_map into a single mb_map. Reviewed by: wollman Notes: svn path=/head/; revision=21737
* Make the long-awaited change from $Id$ to $FreeBSD$Jordan K. Hubbard1997-01-141-1/+1
| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise. Notes: svn path=/head/; revision=21673
* Add an option "EXTRA_VNODES" to cause an extra number of vnode structuresPeter Wemm1996-05-311-1/+6
| | | | | | | | | | | | | | | | | | | to be allocated at boot time. This is an expensive option, as they consume physical ram and are not pageable etc. In certain situations, this kind of option is quite useful, especially for news servers that access a large number of directories at random and torture the name cache. Defining 5000 or 10000 extra vnodes should cut down the amount of vnode recycling somewhat, which should allow better name and directory caching etc. This is a "your mileage may vary" option, with no real indication of what works best for your machine except trial and error. Too many will cost you ram that you could otherwise use for disk buffers etc. This is based on something John Dyson mentioned to me a while ago. Notes: svn path=/head/; revision=16025

| | | | | | | | | | | | | | | in machdep.c (it should use the global nmbclusters). Moved the calculation of nmbclusters into conf/param.c (same place where nmbclusters has always been assigned), and made the calculation include an extra amount based on "maxusers". NMBCLUSTERS can still be overrided in the kernel config file as always, but this change will make that generally unnecessary. This fixes the "bug" reports from people who have misconfigured kernels seeing the network "hang" when the mbuf cluster pool runs out. Reviewed by: John Dyson Notes: svn path=/head/; revision=8747

* These changes embody the support of the fully coherent merged VM buffer cache,David Greenman1995-01-091-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | much higher filesystem I/O performance, and much better paging performance. It represents the culmination of over 6 months of R&D. The majority of the merged VM/cache work is by John Dyson. The following highlights the most significant changes. Additionally, there are (mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to support the new VM/buffer scheme. vfs_bio.c: Significant rewrite of most of vfs_bio to support the merged VM buffer cache scheme. The scheme is almost fully compatible with the old filesystem interface. Significant improvement in the number of opportunities for write clustering. vfs_cluster.c, vfs_subr.c Upgrade and performance enhancements in vfs layer code to support merged VM/buffer cache. Fixup of vfs_cluster to eliminate the bogus pagemove stuff. vm_object.c: Yet more improvements in the collapse code. Elimination of some windows that can cause list corruption. vm_pageout.c: Fixed it, it really works better now. Somehow in 2.0, some "enhancements" broke the code. This code has been reworked from the ground-up. vm_fault.c, vm_page.c, pmap.c, vm_object.c Support for small-block filesystems with merged VM/buffer cache scheme. pmap.c vm_map.c Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of kernel PTs. vm_glue.c Much simpler and more effective swapping code. No more gratuitous swapping. proc.h Fixed the problem that the p_lock flag was not being cleared on a fork. swap_pager.c, vnode_pager.c Removal of old vfs_bio cruft to support the past pseudo-coherency. Now the code doesn't need it anymore. machdep.c Changes to better support the parameter values for the merged VM/buffer cache scheme. machdep.c, kern_exec.c, vm_glue.c Implemented a seperate submap for temporary exec string space and another one to contain process upages. This eliminates all map fragmentation problems that previously existed. ffs_inode.c, ufs_inode.c, ufs_readwrite.c Changes for merged VM/buffer cache. Add "bypass" support for sneaking in on busy buffers. Submitted by: John Dyson and David Greenman Notes: svn path=/head/; revision=5455
