commit 3f7ad298fd5dd80c0dc017fdd77be23e7861e547
Merge: 3496138 a12a106
Author: Samuel Thibault <address@hidden>
Date: Sat Jan 28 23:28:48 2012 +0100
Merge branch 'master' into master-slab
commit 3496138ca428a7b2b69fe08e69fb544006a9a2cc
Author: Richard Braun <address@hidden>
Date: Mon Jan 9 10:01:56 2012 +0000
Improve ipc hash/marequest init readability
Use macros instead of raw numeric values.
* ipc/ipc_hash.h (IPC_HASH_GLOBAL_SIZE): New macro.
* ipc/ipc_hash.c (ipc_hash_init): Directly set the global hash table
size to IPC_HASH_GLOBAL_SIZE.
* ipc/ipc_marequest.h (IPC_MAREQUEST_SIZE): New macro.
* ipc/ipc_marequest.c (ipc_marequest_init): Directly set the marequest
hash table size to IPC_MAREQUEST_SIZE.
commit 88382234bb540544a3550d1ddfb84e0d17eec971
Author: Richard Braun <address@hidden>
Date: Sat Dec 17 21:43:48 2011 +0000
Remove arbitrary limits used by the zone system
The zone allocator could limit the size of its zones to an arbitrary
value set at zinit() time. There is no such parameter with the slab
module. As a result of removing those limits, the kern/mach_param.h
header becomes empty, and is simply removed altogether.
* Makefrag.am (libkernel_a_SOURCES): Remove kern/mach_param.h.
* i386/i386/fpu.c: Remove #include <kern/mach_param.h>.
* i386/i386/machine_task.c: Likewise.
* i386/i386/pcb.c: Likewise.
* ipc/ipc_init.c: Likewise.
(ipc_space_max): Remove variable.
(ipc_tree_entry_max): Likewise.
(ipc_port_max): Likewise.
(ipc_pset_max): Likewise.
* ipc/ipc_init.h (IPC_ZONE_TYPE): Remove macro.
(ipc_space_max): Remove extern declaration.
(ipc_tree_entry_max): Likewise.
(ipc_port_max): Likewise.
(ipc_pset_max): Likewise.
* ipc/ipc_hash.c (ipc_hash_init): Don't use ipc_tree_entry_max to
compute ipc_hash_global_size.
* ipc/ipc_marequest.c: Remove #include <kern/mach_param.h>.
(ipc_marequest_max): Remove variable.
(ipc_marequest_init): Don't use ipc_marequest_max to compute
ipc_marequest_size.
(ipc_marequest_info): Return (unsigned int)-1 in maxp.
* kern/act.c: Remove #include <kern/mach_param.h>.
* kern/mach_clock.c: Likewise.
* kern/priority.c: Likewise.
* kern/task.c: Likewise.
* kern/thread.c: Likewise.
* vm/memory_object_proxy.c: Likewise.
* vm/vm_fault.c: Likewise.
commit aef06eb95fdb3e5f5b857a8b641723759e850a85
Author: Richard Braun <address@hidden>
Date: Sat Dec 17 21:25:23 2011 +0000
Remove the defunct kernel_task_create() function
The kmem_suballoc() function, which has been replaced with
kmem_submap(), is called by kernel_task_create(). Rather than update it,
remove this now unused function.
* kern/task.c (kernel_task_create): Remove function.
* kern/task.h (kernel_task_create): Remove prototype.
commit 5988ae8fb41ace936e48e5a972abe1c5acc8f8af
Author: Richard Braun <address@hidden>

commit 7fa0de680bbfed02e09ad517788fe336c0d855cc
Author: Richard Braun <address@hidden>
Date: Sat Dec 17 16:23:33 2011 +0000
Adjust VM initialization
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.

(kentry_data_size): Initialize to arbitrary value.

* vm/vm_map.h (vm_map_setup): New prototype.
* vm/vm_kern.c (kernel_map_store): New variable.
(kernel_map): Point to kernel_map_store.
(kmem_suballoc): Remove function. Replaced with...
(kmem_submap): New function.
(kmem_init): Call vm_map_setup() instead of vm_map_create().
* vm/vm_kern.h (kmem_suballoc): Remove prototype.
(kmem_submap): New prototype.
* vm/vm_object.c (kernel_object_store): New variable.
(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/ipc_init.c (ipc_kernel_map_store): New variable.
(ipc_kernel_map): Point to ipc_kernel_map_store.
