2001-12-05If we assume (just pure speculation) that there will be a pmap sometime inArtur Grabowski
the future that wants to allocate pv entries for every pmap_enter and wants to allocate those pv entries from kmem_map, it might be a good idea to init the kmem_map before initializing the kmemusage struct (because kmemusage allocates memory).
2001-12-05make nkmempages dynamic based on memory. okay art@ from netbsd:Niels Provos
date: 2000/02/11 19:22:52; author: thorpej; Add some very simple code to auto-size the kmem_map. We take the amount of physical memory, divide it by 4, and then allow machine dependent code to place upper and lower bounds on the size. Export the computed value to userspace via the new "vm.nkmempages" sysctl. NKMEMCLUSTERS is now deprecated and will generate an error if you attempt to use it. The new option, should you choose to use it, is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and NKMEMPAGES_MAX allow the user to configure the bounds in the kernel config file.
2001-12-05Oops forgot to regen.Artur Grabowski
2001-12-05Break out the part that lowers v_holdcnt in brelvp into an own functionArtur Grabowski
and make it and vhold into public interfaces.
2001-12-04Yet another sync to NetBSD uvm.Artur Grabowski
Today we add a pmap argument to pmap_update() and allocate map entries for kernel_map from kmem_map instead of using the static entries. This should get rid of MAX_KMAPENT panics. Also some uvm_loan problems are fixed.
2001-12-04Readd VOP_MMAP, will be used soon. Right now it's just a question toArtur Grabowski
the filesystem if we're allowed to mmap the file.
2001-12-04Add declaration of "state" to _simple_lock_assert(). Since it isTodd C. Miller
an int this can safely be omitted but it is bad style to do so. Closes PR 2223.

This time we're getting rid of KERN_* and VM_PAGER_* error codes and use errnos instead.

2001-11-27fix an error in sosend() that could make a transient error permant.Niels Provos
verified with both netbsd and freebsd. from netbsd: Tue Jun 8 02:39:57 1999 UTC by thorpej In sosend(), if so_error is set, clear it before returning the error to the process (i.e. pre-Reno behavior). The 4.4BSD behavior (introduced in Reno) caused transient errors to stick incorrectly. This is from PR #7640 (Havard Eidnes), cross-checked w/ FreeBSD, where Bill Fenner committed the same fix (as described in a comment in the Vat sources, by Van Jacobsen).
2001-11-27change socket connection queues to use TAILQ_Niels Provos
from NetBSD: Wed Jan 7 23:47:08 1998 UTC by thorpej Make insertion and removal of sockets from the partial and incoming connections queues O(C) rather than O(N).

2001-11-27regen for UBC changesArtur Grabowski
2001-11-27Merge in the unified buffer cache code as found in NetBSD 2001/03/10. TheArtur Grabowski
code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>. Tested for the past few weeks by many developers, should be in a pretty stable state, but will require optimizations and additional cleanups.
2001-11-21Added vfs_isbusy. Useful for verifying that a mount point is lockedConstantine Sapuntzakis
Added vfs_mount_foreach_vnode. Several places in the code seem to want to traverse the mount list and they all seem to handle locking differently. Centralize traversing the mount list in one place so that we only need to get the locking right once.

2001-11-15Remove creds from struct buf, move the creds that nfs need into the nfs node.Artur Grabowski
While in the area, convert nfs node allocation from malloc to pool and do some cleanups. Based on the UBC changes in NetBSD. niklas@ ok.

2001-11-15Don't zero v_bioflag when recycling a vnode in getnewvnode.Artur Grabowski
Sometimes the vnode can be on the syncers list. While that is a bug, it's just a minor annoyance. A vnode on a syncer worklist without VBIOONSYNCLIST set is a disaster.
2001-11-15Make sure that stuff on the syncer worklist has VBIOONSYNCLIST setArtur Grabowski
and stuff that isn't on the worklist doesn't have it set.

Use where VTEXT was set in vnode flags before. Doesn't do anything else (yet).

UBC, but prerequsites for it. - Create a daemon that processes async I/O (swap and paging in the future) requests that need processing in process context and that were processed in the pagedaemon before. - Convert some ugly ifdef DIAGNOSTIC code to less intrusive KASSERTs. - misc other cleanups.
