mycroft 7263209ce6 Make each disk and tape driver define its own read and write functions.
Deprecate rawread() and rawwrite() completely.  Remove d_strategy from cdevsw to
force the abstraction barrier.

cgd 9141ec70a1 change needed for atari; recycle some code for the i386 that was in Lite
that we don't use, but is used by the atari now.  (it should change
to MACHINE_NONCONTIG, too...)

pk 3e4bf211c6 Use vm_object_prefer() to find a good range of virtual addresses to
map a memory object to.
1994-12-10 11:48:12 +00:00
pk d114baba9a Introduce vm_object_prefer(), which interrogates the PMAP layer in search
for an optimal virtual address for a given object.

mycroft 331b95bd8a Garbage collect unneeded variable. 1994-12-01 15:39:17 +00:00
gwr 1a7920257d Make sure vm_mmap creates mappings with page-aligned file offsets.
Handle non-aligned file offsets in the mmap/munmap system calls.
1994-12-01 00:23:11 +00:00
gwr 0a0c02cd38 Allow vm_page_array to have holes in it so systems that use
MACHINE_NONCONTIG can use a fast, simple pmap_page_index().

cgd 0a930e5ce6 redo that last change, correctly. (suggested by mycroft.) 1994-10-30 19:11:09 +00:00

cgd 4eb752cd51 make the "wait on swbuf" message SDB_IO -- it's I/O related, and it's
not at all anomalous (and bloody annoying!) on 4M machines.
1994-10-18 06:42:28 +00:00
mycroft ab9caa0e9a Fix the munmapfd() prototype, too. 1994-09-16 02:01:49 +00:00
mycroft d5fdf729f2 All of the users of munmapfd() expect to pass it
two args.  Make it work correctly.
1994-09-16 01:57:57 +00:00
mycroft 6dd2f9eed2 vm_object_page_clean() expects to be able to use vm_page_deactivate() on a
locked page.  Make that work.  This also obviates the need for vm_fault() to
bogusly activate a page before deactivating it.  Finally, make sure the
semantics of vm_object_deactive_pages() don't change.
