2014-02-06vm: trigger garbage collection on kernel memory pressureRichard Braun
In addition to physical pages, the slab allocator also consumes kernel virtual memory, so reclaim pages on failure to allocate from a kernel map. This method isn't foolproof but helps alleviate fragmentation. * vm/vm_kern.c (kmem_alloc): Call slab_collect and retry allocation once on failure. (kmem_realloc): Likewise. (kmem_alloc_wired): Likewise. (kmem_alloc_wired): Likewise. (kmem_alloc_aligned): Likewise.
2014-02-04Fix potential NULL dereferenceSamuel Thibault
* vm/vm_kern.c (projected_buffer_deallocate): Look for `map' being NULL or kernel_map before locking it.
2014-01-16vm: remove the declaration of memory_object_create_proxyJustus Winter
It is not clear to me why the declaration was put there in the first place. It is not used anywhere, and it conflicts with the declaration generated by mig. * vm/memory_object_proxy.h (memory_object_create_proxy): Remove declaration.
2014-01-03vm: reduce the size of struct vm_pageJustus Winter
Previously, the bit field left 31 bits unused. By reducing the size of wire_count by one bit, the size of the whole struct is reduced by four bytes. * vm/vm_page.h (struct vm_page): Reduce the size of wire_count to 15 bits.
2014-01-03vm: merge the two bit fields in struct vm_pageJustus Winter
* vm/vm_page.h (struct vm_page): Merge the two bit fields.
2014-01-03vm: remove NS32000-specific padding from struct vm_pageJustus Winter
Apparently, the NS32000 was a 32-bit CPU from the 1990ies. The string "ns32000" appears nowhere else in the source. * vm/vm_page.h (struct vm_page): Remove NS32000-specific padding.
