* use __func__ where possible. shaves 4k and makes indentation much better.fgsch2011-01-051-58/+55

* explicitly specify flags to malloc and pool_get instead of relying on 0.tedu2010-07-031-2/+3
| | | | | This is more clear, and as thib pointed out, the default in softraid was wrong. ok thib.

* Make sure we do not loop when allocating an extent region with EX_CONFLICTOKmiod2009-10-131-7/+11
| | | | | | | and the whole extent is used; the current code computations would wrap. Found the hard way by jsg@, fix discuss with kettenis@, and you get a regress test for free (which will spin if you compile it again an old subr_extent.c)
* Make sure we handle all possible ways regions can overlap when EX_CONFLICTOKkettenis2009-09-181-9/+26

* Fix userland regression tests by providing a #define for pool_setipl()oga2009-06-091-2/+2
| | | | | | (just a noop since that doesn't matter in userland). Pointed out by a couple of people, thanks.
* don't use splvm ourselves, use pool_setipl on the pool we're allocatingoga2009-06-041-11/+2

* Add a new EX_FILLED flag to make extent_create() create an extent map thatkettenis2009-04-191-1/+13

* Make extent_print() use printf to avoid the pagination that db_printfkettenis2009-04-041-9/+17
| | | | | provides, while keeping this behaviour for extent_print_all() which is only called by ddb. Based on a diff from deraadt@.
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-261-8/+1
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
* In extent_destroy(), only remove the extent from the global extent list ifmiod2006-06-041-1/+3
| | | | the list is really used, i.e. if option DIAGNOSTIC || option DDB.

* Two patches from NetBSD:jason2002-03-211-16/+25
| | | | | | | | | - extent_alloc_subregion shouldn't allocate a region pasts the end of subregion. - extent_alloc_subregion1(): when a candidate region doesn't fit after being rounded up to respect boundary limits, adjust newstart and last before skiping to the next region. Otherwise we may check the same candidate region against the start of the next region, no the one immediatly following the hole, leading to corrupted map.

* Pool deals fairly well with physical memory shortage, but it doesn't dealart2002-01-231-2/+2
| | | | | | | | | | | | | | | | | | 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 serious bug in extent_alloc_subregion where the subregion startfgsch1998-10-011-1/+20

* Add command to print out extents. This helps in debugging PnP stuff,weingart1998-02-251-3/+9

* Add some more extent stuff, in preperation of PnP. Huh? Did Iweingart1997-07-121-1/+62
| | | | | | | | say PnP? Anyways, this stuff just adds the ability to register the extents on creation, etc, etc... Someone needs to add a DDB command "show extent", to make this really usefull... ;-)
