* Remove more '\n's from panic() statements. Both trailing and leading.krw2002-10-121-4/+4
| | | | Diff generated by Chris Kuethe.
* Fix yet another braino.art2002-07-231-2/+11
| | | | | | | | Just because the pool allocates from intrsafe memory doesn't mean that the pool has to be protected by splvm. We can have an intrsafe pools at splbio or splsoftnet. pool_page_alloc and pool_page_free must du their own splvm protection.
* Please tell me what crack I've been smoking when I did that.art2002-07-231-7/+7
| | | | | | When trying the drain hook just in pool_allocator_alloc, don't leak memory when the drain succeeds and don't avoid draining other pools if this pool doesn't have a drain hook.

* If the allocator has the PA_WANT flag set, return whole pages immediately.art2002-02-231-2/+3

* Fix up some functions. Don't have static all over the placeart2002-02-231-14/+17
| | | | | and don't static inline big functions that are called multiple times and are not time critical.
* Honor the printf-like function argument in pool_printit(), instead ofmiod2002-01-291-3/+3

* GC PR_STATIC and PR_MALLOCOK.art2002-01-281-26/+4
| | | | | PR_MALLOC wasn't used at all in the code and PR_STATIC was missing pieces and should be solved with allocators.
* Add a drain hook to each pool. This hook is called in three cases.art2002-01-251-2/+52
| | | | | | | | | | | | 1. When a pool hit the hard limit. Just before bailing out/sleeping. 2. When an allocator fails to allocate memory (with PR_NOWAIT). 3. Just before trying to reclaim some page in pool_reclaim. The function called form the hook should try to free some items to the pool if possible. Convert m_reclaim hooks that were embedded in MCLGET, MGET and MGETHDR into a pool drain hook (making the code much cleaner).
* Kill PR_FREEHEADER, not used anymore and confusing.art2002-01-231-4/+1

* Pool deals fairly well with physical memory shortage, but it doesn't dealart2002-01-231-102/+206
| | | | | | | | | | | | | | | | | | well (not at all) with shortages of the vm_map where the pages are mapped (usually kmem_map). Try to deal with it: - group all information the backend allocator for a pool in a separate struct. The pool will only have a pointer to that struct. - change the pool_init API to reflect that. - link all pools allocating from the same allocator on a linked list. - Since an allocator is responsible to wait for physical memory it will only fail (waitok) when it runs out of its backing vm_map, carefully drain pools using the same allocator so that va space is freed. (see comments in code for caveats and details). - change pool_reclaim to return if it actually succeeded to free some memory, use that information to make draining easier and more efficient. - get rid of PR_URGENT, noone uses it.
* Fix a locking error in pool_drain. Misc cleanup.art2002-01-101-30/+63

* Bring in a bunch of improvements from NetBSD.art2001-06-231-268/+548
| | | | | | | - pool_cache similar to the slab allocator in Solaris. - clean up locking a bit. - Don't pass __LINE__ and __FILE__ to pool_get and pool_put unless POOL_DIAGNOSTIC is defined.
