SVN rev 196838 on 2009-09-04 19:59:32Z by jhb
MFC 193396, 193521, 194331, 194337, 194376, 194454, 194562, 194642, 195033,
195385, 195649, 195660, 195749, and 195774:
Add support to the virtual memory system for configuring machine-
dependent memory attributes:
- Refactor contigmalloc() into two functions: a simple front-end that deals
with the malloc tag and calls a new back-end, kmem_alloc_contig(), that
allocates the pages and maps them.
- Use kmem_alloc_contig() to implement the UMA back-end allocator for
jumbo frame zones.
- Use kmem_alloc_contig() to allocate the top-level page tables for PAE.
- Introduce vm_memattr_t to as a type to hold memory attributes.
- Introduce vm_object_set_memattr() for setting the default memory
attributes that will be given to an object's pages.
- Introduce and use pmap_page_{get,set}_memattr() for getting and
setting a page's machine-dependent memory attributes. Add full
support for these functions on amd64 and i386 and stubs for them on
the other architectures. The function pmap_page_set_memattr() is also
responsible for any other machine-dependent aspects of changing a
page's memory attributes, such as flushing the cache or updating the
direct map. The uses include kmem_alloc_contig(), vm_page_alloc(),
and the device pager:
kmem_alloc_contig() can now be used to allocate kernel memory with
non-default memory attributes on amd64 and i386.
vm_page_alloc() and the device pager will set the memory attributes
for the real or fictitious page according to the object's default
memory attributes.
- Update the various pmap functions on amd64 and i386 that map pages to
incorporate each page's memory attributes in the mapping.
