make pageout sleep on vm_pages_needed rather than lbolt. this stops
...
pathological behaviour (freezes) when running short of free pages. see
PR#2755 for a more detailed explanation (from jonathan).
thanks to john dyson for the first cut of this change.

left, rather than panic()ing. This allows callers to set their own policy
for how to handle the shortage. Add a few comments.

fix a printf warning and add pmap_page_index declaration
1996-02-12 21:51:52 +00:00
d0fd3d7e62
Don't declare pmap_page_index for now. It will break the arm port.
...
This clearly needs to be fixed. I would like to declare it:
__pure u_int pmap_page_index __P((vm_offset_t));
but at least the arm port wants it signed [since it tests for -1 all over
the place]. Can we have this fixed please?

Extend use of vm_object_prefer() to vm_allocate_with_pager().
...
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.
Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.
