I need to share about 100megs of memory between kernel and userspace. The memory can not be paged and should appear contig in the process's address space. Any suggestions? I need a way to either: map user memory into the kernel's address space. map kernel memory into the user's address space. I was looking at pmap_qenter() but it didn't see attractive because it's for "short term mappings", this mapping will exist for quite a while. -- - Alfred Perlstein - Research Engineering Development Inc. - email: bright@mu.org cell: 408-480-4684
