alc 2010-04-09 02:39:20 UTC FreeBSD src repository Modified files: sys/vm vm_contig.c vm_extern.h Log: SVN rev 206409 on 2010-04-09 02:39:20Z by alc Introduce the function kmem_alloc_attr(), which allocates kernel virtual memory with the specified physical attributes. In particular, like kmem_alloc_contig(), the caller can specify the physical address range from which the physical pages are allocated and the memory attributes (i.e., cache behavior) for these physical pages. However, in contrast to kmem_alloc_contig() or contigmalloc(), the physical pages that are allocated by kmem_alloc_attr() are not necessarily physically contiguous. This function is needed by DRM and VirtualBox. Correct an error in the prototype for kmem_malloc(). The third argument had the wrong type. Tested by: rnoland MFC after: 3 days Revision Changes Path 1.74 +97 -18 src/sys/vm/vm_contig.c 1.92 +3 -1 src/sys/vm/vm_extern.h
