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.
|
|
* vm/vm_kern.c (projected_buffer_deallocate): Look for `map' being NULL
or kernel_map before locking it.
|
|
The return value from vm_map_min() is already of vm_offset_t type.
* vm/vm_kern.c (kmem_submap) (addr): Remove unnecessary cast.
|
|
* vm/vm_kern.c (kmem_alloc_pages, kmem_remap_pages): Remove forward declarations.
* vm/vm_kern.h (kmem_alloc_pages, kmem_remap_pages): Add prototypes.
|
|
* vm/vm_kern.c: Remove register qualifiers.
|
|
Unlike the zone allocator, the slab code can't be fed with an initial
chunk of memory. Some VM objects used early during startup now have to
be statically allocated, and kernel map entries need a special path
to avoid recursion when being allocated.
* vm/vm_map.c (vm_submap_object_store): New variable.
(vm_submap_object): Point to vm_submap_object_store.
(kentry_data_size): Initialize to arbitrary value.
(kentry_count): Remove variable.
(kentry_pagealloc): New function.
(vm_map_setup): Likewise.
(vm_map_create): Replace initialization with a call to vm_map_setup().
* vm/vm_map.h (vm_map_setup): New prototype.

(kernel_object): Point to kernel_object_store.
(vm_object_template): Change type from vm_object_t to struct vm_object.
(_vm_object_setup): New function.
(_vm_object_allocate): Replace initialization with a call to
_vm_object_setup().
(vm_object_bootstrap): Don't allocate vm_object_template, and use it as
a structure instead of a pointer. Initialize kernel_object and
vm_submap_object with _vm_object_setup() instead of
_vm_object_allocate().
* vm/vm_resident.c (vm_page_bootstrap): Don't initialize
kentry_data_size.
* device/ds_routines.c (device_io_map_store): New variable.
(device_io_map): Point to device_io_map_store.
(mach_device_init): Call kmem_submap() instead of kmem_suballoc().

(ipc_kernel_map): Point to ipc_kernel_map_store.
|
|
* kern/printf.h (printf_once): New macro.
* ipc/mach_port.c (mach_port_names, mach_port_get_set_status): Warn when
returning KERN_RESOURCE_SHORTAGE.
* vm/vm_kern.c: Include printf.h.
(kmem_alloc, kmem_realloc, kmem_alloc_wired, kmem_alloc_aligned,
kmem_alloc_pageable): Warn when failing.
* vm/vm_resident.c (vm_page_grab_contiguous_pages): Warn when returning
KERN_RESOURCE_SHORTAGE.

function prototypes.

* vm/vm_kern.c (projected_buffer_deallocate): Give &map->hdr
instead of map to _vm_map_clip_start and _vm_map_clip_end functions.
2008-12-01 Samuel Thibault <samuel.thibault@ens-lyon.org>
* device/device_emul.h (device_emulation_ops): Turn back reference,
dealloc, dev_to_port, write_trap and writev_trap into taking a void*,
as they do not always take a mach_device_t.
* device/ds_routines.c (mach_device_emulation_ops): Cast
mach_device_reference, mach_device_deallocate,
mach_convert_device_to_port, device_write_trap and device_writev_trap
to (void*) to make them accept a void* argument.
* linux/pcmcia-cs/glue/ds.c (device_deallocate): Rename function
into...
(ds_device_deallocate): ... this.
(dev_to_port): Call ds_device_deallocate instead of device_deallocate.

accept a void* argument.
