2015-08-26kern/slab: directmap updateRichard Braun
The main impact of the direct physical mapping on the kmem module is the slab size computation. The page allocator requires the allocation size to be a power-of-two above the page size since it uses the buddy memory allocation algorithm. Custom slab allocation functions are no longer needed since the only user was the kentry area, which has been removed recently. The KMEM_CACHE_NOCPUPOOL flag is also no longer needed since CPU pools, which are allocated from a kmem cache, can now always be allocated out of the direct physical mapping.

2009-11-28Add memory object proxiesSamuel Thibault
Memory object proxies permit to replicate objects with different parameters, like reduced privileged, different offset, etc. They are e.g. essential for properly managing memory access permissions. 2005-06-06 Marcus Brinkmann <marcus@gnu.org> * include/mach/mach4.defs: Add memory_object_create_proxy interface. * Makefile.in (vm-cfiles): Add memory_object_proxy.c. * i386/include/mach/i386/vm_types.h (vm_offset_array_t): New type. * include/mach/memory_object.h (memory_object_array_t): New type. * vm/memory_object_proxy.c: New file. * kern/ipc_kobject.h: New macro IKOT_PAGER_PROXY. Bump up macros IKOT_UNKNOWN and IKOT_MAX_TYPE. * kern/ipc_kobject.c (ipc_kobject_notify): Call memory_object_proxy_notify for IKOT_PAGER_PROXY. * vm/vm_init.c (vm_mem_init): Call memory_object_proxy_init. * vm/vm_user.c (vm_map): Implement support for proxy memory objects.
